View Full Version : Jope's A1700..
I had a spare A1200 mobo kicking around that I originally bought "broken for spares" from a friend of mine here in Finland.
One day I remembered it and thought I might as well boot it up and see what happens.
Well wouldn't you know! It actually boots up..
The keyboard controller area looked rather bad + the keyboard connector was melted due to someone carelessly replacing the U7 CIA with a hot air gun..
Oh well. Plenty of broken A500s in my cupboard. Whip the motherboard out of one, and insert A1200 mobo?
After some knife work, I now have the A1200 motherboard fitted inside the A500 case. The motherboard is mounted down with copious amounts of rolled up duct tape. Duct tape is not as permanent as double sided, but I can take the mobo out easily if need be.
What next, thinks our intrepid protagonist..
Well a keyboard would be nice, I guess?
So I removed the LED + GND wires from the A500 keyboard connector and just stuck them in the A1200 motherboard's led pin strip. Power it up and hey I have power and drive leds.
It sure would be nice to be able to type on that thing too so I dig out some pin strip and wire and solder the remaining four connections (CLK, DAT, _RESET, +5V) from the pin strip onto the A1200's CIA and KBD controller. This way I can easily remove the keyboard later. :-)
What's this, just '''' when I type. Well, you as well as I know that CLK and DAT are reversed. Quickly desolder and swap them around, connect everything up, boot, and whee I can type legible text and reset the machine from the keyboard.

Oh yeah I guess you want a picture too? Here it is, with a tall A4000 HD floppy mechanism on my very cluttered desk:
http://jope.fi/amiga/a1700/a1700.jpg
What next? I don't know. It has a 28MHz 020 turbo with 4MB ram and 3.0 ROMs.. I guess I might be arsed to burn some 3.1 or 3.9 ROMs for it and I have a bunch of CF2IDE adapters lying around, just need some CFs and a 44pin IDE cable. WHDLoad machine or what ever. That clock port also beckons me somehow on the motherboard .. what should I plug in there?
Oh, it's ever so fast..

Good work m8y, a nice see indeed..
A1200 in an a500 chassis would be interesting to see an optical drive in there too!
can we all have a nice close up of the keyboard adapter and u7 soldering :D

Heh.. Perhaps I'll just forget about it.. An optical drive does sound doable, however..
I remember seeing some ancient laptop mechanisms with a 44pin connector at the local recycling center. Sounds like something suitable for a low-budget project such as this. :-)
Re-housing an A1200 into an A500 case - great idea - loads more room!
indeedy i have wanted to do this for some time...
in there would a be a rom, two hard disks (a 4GB boot and 120GB ) and an external CF backplane built into it some where.
an 030@50 with 32/64MB with a prelude sound card and a USB so i could network it with a dongle or two..... hmmm i wonder if there is enough room to add a simple zorro2 pass through an a right angle zorro2 adapter lol ...

Good work chap, what do the ports look like at the back as IIRC they're laid out differently on the 1200 are they not?! :D
@jope
we demand more quality pics. :D
please
Where would you like pics taken?
The ports at the back are now surrounded by one wide rectangular hole in the plastic.. I just used wire cutters and a knife to remove some plastic.. (I don't have a dremel)
I purchased the optical drive this morning. 10 euro from the local recycling center.. I got one with a 44pin interface, so I don't have to buy a separate adapter board for it. There's a huge pile of old laptop CD mechanisms there, so I just had to dig around a bit. I don't know how fast it is .. probably around 4x-8x. Doesn't really matter.
Now I'm waiting for some 44pin IDE cables with three connectors.. I decided I can't be arsed to crimp them myself, so I bought a set of four off ebay.
The optical drive is probably going to be installed on the left hand side of the machine. I want to keep the floppy drive inside the case too.

Then a couple of macro shots.. I didn't really pay attention to making it look nice, as it was more of a "proof of concept" type modification than anything else.

At least you can see how much the A1200 motherboard is wider. I had to elongate the hole at the back almost the width of the DB9 port and half the width of the power connector.

well done (especialy for some one without a dremel)
c'mon jope-a-licious you can get one for less than £15 on fleabay... where ya excuses!? lol.
My excuses are many, but the most important one is that I'm very lazy. I could just go down to the hardware store to purchase one, but I choose not to! :-D
You wouldn't believe how often I'd have needed one, though.. Perhaps I'll buy it when I walk past one next time. :-)
Methanoid
06 July 2007, 13:38
and so it begins!!!... as proof of concept... consider it proofed!
I own Dremel and I'm buying the bits off the Bay or wherever. My aim is the same but with an internal PSU (ST stylee). If there is more room left then we'll do the CD,HD, accelerator etc route afterwards.
Given that 90% of A500s are old and discoloured I think a respray in a nice bright white satin finish is also in order. And in homage to the A530 Pimping the whole thing to be buffed up as well.
And as long as it says A500 on the outside the wife will think it was "some bootfair bargain" and not moan at the money it costs!
Win-Win situation!! (at least thats my plan!)
@Methanoid,
consider a 60watt PicPSU solution (i have a 120watt on my current project and its awsome!)
its very tiny, provides all the voltages a growing amiga needs, and runs from a laptop plug-pack!
so you should be able to get these NEW for arround £20 - £30 and laptop plugpacks (6v - 19v @ 10 - 3amps) respectively :D
theres plent-o room under the floppy drive to mount the mechanism, and you can remove the exising power plug connector and mount the standard two pin connector in its place.. all you have to do then is decided where you want your ON button :D

Great work jope - I agree with Zetr0 - A Dremel would be a bonus, also you can buy some really small, fine files that really help when you need to take the rough edges off the casing - I did quite a bit of delicate filing when I put the USB ports for the Subway into an A1200 casing ... I have nearly finished my Tower set up ... this is making me think what to do next... maybe some more A1200 case cutting and DVD Rom installation I think - where's the dremel...?

I don't get it. Your 28 MHz 68020 is exactly as fast as my 33 MHz 68030 A1200?? (1.05x A3000)
What goes on here....??
rkauer
18 September 2009, 05:02
Without activating all the 030 extra features the behave of it is comparable of the 020.
In fact, they are almost the same CPU, where the 020 just lacks the built-in MMU.
As a matter of curiosity: Motorola used a scheme to name teh chips on that era. the final two digits are even for major upgrade on the line, odd digits to minor differences.
68000 - 68010: '010 fixes some small bugs in the '000 and improve some few instructions. Can break old programs who relies on the buggy '000...
68020 - 68030: built-in MMU and higher clock rates
68040 and 68060 don't have minor revisions CPU upgrades.

18 September 2009, 07:20
What?
A 040 25MHz is faster than a 030 50MHz....
Explain?
Shadowfire
18 September 2009, 15:27
Yeah, the '040 introduced a whole slew of new features (copyback cache, larger cache, and multiple pipelines).
Zetr0
18 September 2009, 16:22
@8bitbubsy
a 25mhz 040 is aproximately twice as fast as a 50mhz 030, as shadowfire points out the 040 had a lot more in it, like the integration of an MC68030-compatible integer unit (IU) and two independent caches. the none EC models also contain dual, independent, demand-paged memory management units (MMUs) for instruction and data stream accesses and independent, 4-Kbyte instruction and data caches.
hence a lot more powerfull than a traditional 030.
there was some white paper design for the 68050, but (IF) i remember correctly they changed manufactoring processes and reduced the nanometer size of the construction, so they skipped the 050 and went straight to the 060 adding super scalar integer (100mips at 66mhz, thats nearly 4 times faster than an 040@50mhz ), branch predicticing ,the 060 also employs a deep pipeline, dual issue superscalar execution, a branch cache, eight Kbytes each of on-chip instruction and data caches, with dual on-chip demand paging MMUs (MC68060 and MC68LC060 only). The MC68060 allows simultaneous execution of two integer instructions (or an integer and a float instruction) and one branch instruction during each clock!!!
the 060 is an amazing cpu.... i love it =D

18 September 2009, 17:43
Suddenly I'm beginning to think Motorola made 3 CPUs in 15 years...
Anyway, would be interesting to drop a 68020 core in a gate array and see how fast you can get with today's frequencies, caches and stuff.

Well, ok. I had a memory 040 was at least 5x the speed of 030 at the same clock. Well, pretty close.
My A500-040 (28MHz) is 4.28 x A3000 (25 MHz 68030). Dunno if faster chipmem on the A3000 affects the comparison.
So um we're both right ... or something :)

Just asking here in case you didn't see my post in keyboard membranes thread: Will the n-key rollover thing become better with an A500 keyboard? In case the little glitch doesn't affect a simple 5/6-pin connection...
Unless the problem is with the A1200 keyboard flatcable... I had that problem where all keys worked separately but combos like alt+amiga didn't (locked out each other)

It does, as it is not a problem with the mechanics of the A1200 keyboard, but the controller that lives on the motherboard is shit.
Unless the problem is with the A1200 keyboard flatcable... I had that problem where all keys worked separately but combos like alt+amiga didn't (locked out each other)
Nopes, the membrane and flat cable are 99% the same as in the A500. The major difference is, that it comes out from the middle of the keyboard, instead of above Del/Help. Just be sure not to use one of the less common A500 keyboards with two flat cables. The majority have just one, and this is what you want.
It's easier to just plug the A500 controller into the A1200 flat cable, then wire it up. If you use an A500 keyboard in the A1200 case, it will hit the power and drive leds in the A1200 case and not fit together.
Photon
21 October 2009, 15:45
Yes, well that collision can be avoided with a saw and and hammer. I mean modding :)
"Plug the controller into the A1200 flat cable" makes no sense to me :) but I guess I can go by the photo of your mod and replicate it?
Apparently I don't have to remove the chip? Won't that chip interfere with the controller on the A500 keyboard? Or did you simply nip off the +Vcc pin?
Jope
21 October 2009, 15:56
Yes, well that collision can be avoided with a saw and and hammer. I mean modding :)
Please, no. The A1200 has a perfectly fitting keyboard + led board, why on earth would you want to ugly it up?
"Plug the controller into the A1200 flat cable" makes no sense to me :) but I guess I can go by the photo of your mod and replicate it?
Well you can look at my photos for how the wires hook up to the A1200 motherboard, but the similarities end there..
Let's go through the A500 controller board into A1200 keyboard thing again:
There's a wide plastic cable snaking out from the back of the A1200 keyboard that plugs into the A1200 motherboard. This much is agreed upon, I'm sure.
Now take the A500 keyboard into your hand and look closely between the keyboard controller and the black plastic in the top right corner. There is a very short piece of plastic cable visible between the controller board and the keyboard itself.
Unscrew the little PCB from the corner of the A500 keyboard, then unplug this short piece of cable you see between the mechanism and the PCB so that you have the little PCB free in your hand. You may also need to cut a cable tie that holds the rainbow coloured wires down before it comes loose.
The A1200 keyboard's cable plugs into the same slot on the little PCB (instead of going to the A1200 motherboard), then you just connect the rainbow coloured wires to the correct places on the A1200 motherboard.
If you do it like this, you will not have to hacksaw the case or the keyboard, nor do you have to transfer the white keys to the A500 keyboard..
Apparently I don't have to remove the chip? Won't that chip interfere with the controller on the A500 keyboard? Or did you simply nip off the +Vcc pin?
If it doesn't work with the controller left in, the best way to do this is to cut or bend up the CLK and DAT pins from the A1200 keyboard processor. Don't leave it hanging on the bus unpowered, this might still interfere with the signalling.
Photon
22 October 2009, 19:41
Yeah, it seemed like the leds would fit in the holes, but well, I just had a quick look so wasn't 100% sure.
And I suspected you had disconnected some pins from the mobo - right. Point taken about the bus.
Although it's pretty hard to see all of it on that pic after the previous owner's hot-air gun massacre :) One side of the keyboard controller looks like it's been attacked with hammer and chisel (!)

Hey Jope, did you get to install the CDROM into your A1700?
Jope
04 February 2010, 18:36
I did, yes. I ended up creating a bracket for it that screws into the lip at the back of the computer. To make the bracket, I cut up an A500 AmigaBus grounding strip and soldered it together so that the holes lined up with the laptop drive.
Fits nicely. I originally tried to mount the CD-ROM onto the top cover with hot glue, but naturally it didn't stand transport at all.
I meant to take new pics once I get around to modifying an AmigaBus hole cover to sport a PCMCIA slot opening, but I haven't bothered with that yet, so now pictures and thread updates either. :-)

Jope
18 September 2010, 18:37
So .. long time, no pics. I did something to the machine and decided to snag some new shots while I'm at it.
Its been in use on and off, always a conversation piece at demo parties. I upgraded the crappy TRA turbo with a B1230-IV pretty soon after I took the machine into use. I also found a used Indivision A1200 for a reasonable price some time last year and installed that too.
But that was then, today's project was the PCMCIA hole I was talking about before.
First off, here's what the insides look like at the moment:
http://jope.fi/amiga/a1700/a1700_cluttered.jpg
It's a bit cluttered, since there's a lot of spare flat cable. Makes taking it apart easier.
Here's the hole. :-)
http://jope.fi/amiga/a1700/a1700_pcmcia.jpg
Here's the CD-ROM bracket I mentioned before, fashioned out of a cut down A500 AmigaBus grounding strip:
http://jope.fi/amiga/a1700/a1700_cdbracket.jpg
And it rests in place like this. I also opted to mount the Indivision's VGA port in place of the useless RF modulator.
http://jope.fi/amiga/a1700/a1700_cdromindi.jpg
Everything fits comfortably and it's time to put the cover back on. You can see the two screws that hold the CD-ROM bracket down at the rear of the machine if you squint, it's a little out of focus in that area. :-)
http://jope.fi/amiga/a1700/a1700_alltogether.jpg
Mmm, NMB keyboards.. <3 (still looking for more of these.. A500/A2000 models both accepted. :-)
No-one knows what lurks within.
http://jope.fi/amiga/a1700/a1700_top.jpg
Unfortunately I mounted the CD-ROM too far towards the front at first. I'll do something about it later. Maybe.

I'm still inspired by your A1700, mate. Only thing I want to do with a spare A1200 board (when I get one, as my 1200 died an horrible death) is mounting the CD to the back of the machine using the original grills to hide where the CD/DVD is mounted (routing the eject button to the under side of the back side is the goal, here). I'm still plenty of non-wanted A500 cases on my house (wife complains about the space)...
BTW: my house have more than 300m² of constructed area (the swimming pool is not counted!)...
I think I can help on the subject, but we live too far away...

Hello, love the A1700. Considering doing this to an A1200 I'll be getting soon, so I have maximum room for pimpage. Here's my question, can the A500 case hold an A1200 keyboard? If not what are the mechanical problems.
The keyboard bottom plate is the same shape. The only things I can think of is that the A500 case has holes for only two LEDs, so you can't use the A1200 LED board without modifications, and the A1200's keyboard ribbon cable might not reach the connector, since the motherboard sits a bit further from the keyboard.
Haven't tried it though, as I prefer the older style keyboard controller.

Haven't tried it though, as I prefer the older style keyboard controller.
I have used the A1200 LEDs but you only can see 2 of the them,The power is the HD and the Disk drive is the same,I bent the power LED a bit so so the two LEDs fit in the holes and stuck them on with sticky tape.The power Led still lights up so you see light coming from them when the Amiga is on..;)

Yeh, that will work. :-)
I bodged separate LEDs into my A1260 with hot glue, because I used an A500 keyboard without removing the controller board in it. There was no room for the LED board.

Great, thanks gents. I knew about the extra LED. I might try to slice a nice neat hole in a 500 case for the 3rd one. I just didn't know if the keyboard backplate bit would be held properly by the 500 case. (I don't actually have any of the bits yet you see). :great

Cool,like how you did it.nice work.
Here is a pic of mine,I did it this way cos I don't what make a crapy hole in the top of the case,it only works this way cos of the hole in the keyboard metal frame..;)
I noticed that your bottom part of the case is yellowing like mine,well i got a new-ish one for mine from airey36 on ebay..;) http://www.ebay.co.uk/itm/ws/eBayISAPI.dll?ViewItem&item=310418606732#ht_1118wt_1037
