A1200/600 Clockport?

Amiga1992 · 13 July 2002, 06:13

Just been browsing Eytech;s site and I found many devices that use the "A1200 Clockport" to connect.. .Which port is this? I presume is not the one where my accelerator is conencted to, right?

Id like a Prelude card

The A1200 clockport is this little chap here:

Amiga1992 · 14 July 2002, 03:19

Ohh shite, nice! what was that made for anyway!!??

I think I'd like one of those Prelude soundcards... Are these the ones that decode MP3s by hardware?? oh how sweet

D

Though I'll have to let it be hanging from outside the case :P And perhaps I need a new PSU... damn...

Thanks for the info mate!

Heh, a clock perhaps?

Amiga1992 · 14 July 2002, 09:01

Would be quite strange for a clock to have so many direct accesses to the cpu and a1200 stuff!

i dont care what it was meant to as long as I can put it to good use

adolescent · 14 July 2002, 10:34

Actually, I read before that there was supposed to be chip RAM expansion (like only A501) that could plug into this also. But, that never happened so it's left with I/O devices, sound cards, and ??? It isn't a full feature/speed bus like the trapdoor. Which is why you can't do anything really remarkable with it.

rgen · 14 July 2002, 17:57

Yes Commodore had the very clever plan to deliver A1200s with only one meg chipram. The plug socket of my C= A1200 is even the double size than the one from blackcornflake.

14 July 2002, 17:58

The A1200 was intended to ship with 1MB only, upgradable to 2MB via the clockport expander (which was also designed to accept a realtime clock). It shipped with 2 MB and practically all RAM expansions and turbo cards come with a realtime clock, therefore the clockport was never used for its intended purpose.

It was used for I/O expansions (buffered serial/parallel ports) and soundcards. There are even clockport "expanders", which give you multiple clockports. Several Zorro cards even feature a "clockport-clone", to enable owners of big-box Amigas to use clockport expansions.

Here's a funny one from the Amiga Hardware Book...

http://www.amiga-hardware.com/a1200clock.html

Also, some information about the port itself...

Don't buy one just yet, Akira.

Bad news time: the Prelude comes in two varieties; clockport fitting and Zorro 2. Neither has onboard MP3 decoding hardware as standard. A daughterboard (MPEGit) is available for just this purpose...but only for the Zorro 2 version.

Good news time: Eyetech have produced a clever little MP3 unit, called the 'MAS Player', which connects externally, and works on all Amigas. It connects to both the parallel and serial ports (with pass-through on serial port). No significant CPU usage, no external libs required. Might be worth checking out.

Sorry about the slow info time, but I had to do some research as I do not own any of these items myself.

Amiga1992 · 17 July 2002, 06:12

WOW, thanks for all the GREAT info guys. Things you learn, huh?

I read Eyetech's bit about that external MP3 decoder... sounds interesting!

RetroMan · 17 July 2002, 12:55

Maybe it would be better to get a 1240 or 1260 Turbocard for the A1200 then the MAS Player

You can play mp3´s then as wenn AND you got a REALLY fast A1200

Amiga1992 · 17 July 2002, 15:32

I'm planning to go for an 060 soon, but Im debating if I should get another 1200 mobo and get a PPC card, or wait to see if I get an A3000 and put a PPC inside it instead.

Are you mad?

For retro-stuff, a 68030 is sufficient. There's practically nothing that requires the custom chips and more power than a 1230 can deliver. If you need horsepower, buy Amithlon. Don't buy a PPC card, these beasts are unreliable, extremely expensive and don't give much of a performance boost (unless you want to play ports of PC games...). Even those 1260 cards are still extremely expensive.

Btw., It's probably cheaper to buy an AmigaOne + Voodoo3 (or a cheap 2D only GFX card) than an A3000 + PPC card + Amiga GFX card (this is way better than an A1200PPC). And the A1 is much more powerful

And those Amigas that are upgraded to the max are not much fun anyway - the typical "it's an Amiga, so it's easy to use and doesn't make problems" feeling is lost. I'll be more than happy when I can replace my A1200PPC with an A1. No more crashes at power on (due to the PPC card eating up to much power), no more reboots at cold boot (to get rid of the stupid powerpc.library), no more "machine doesn't boot so let's open the case and make sure that none of add-ons got loose" sessions every few weeks, no more.. well, you get the idea.

Well, if you're going to buy such a setup just because of the cult factor, you're much more fanatic than I though

Well, since the AmigaOne isn't available (or is it now? I can't find one) and it's Amiga compatibility hasn't been proven, then how can this be better? Right now all I've seen are Workbench photos, and nothing else. Sure, it's got better looking menus, and neat gimicks, but there's nothing tangible as of yet.

And, what is a A3000 + PPC + GFX card better for? Office applications, web browsing, what? It's definately not better for running most games (especially AGA

).

Akira was talking about "soon". The A1 will be available soon.

Amiga compatability? It runs modern software that supports RTG and RTA standards. Same goes for Amithlon, so Amithlon prooves the A1's "Amiga compatability" to a certain degree.

Speak for yourself please [strokes the mysterious big grey box standing beneath his A1200T]

It's a much more reliable hardware setup. It's faster. You can use Zorro cards.

Akira already owns an A1200.

Yes there is .... DEMOS

But it's not Amiga custom chip compatible! so I dont want it

I sont use modern Amiga apps. buts Id love a PPC inside a 3000! pimped up 3000s are luvverly

[/B]

I just want the 060 for the DEMOS

I dont need the PPC but I thought "WTF, Ive got a MAD A3000, let's pimp it up to the MAX".

Now I think Ill just get an 060 card

cv643d · 23 July 2002, 17:34

Hmm... new generations demos that requires 060 isnt as much fun as first generation AGA demos or A500 demos in my opinion.

Amiga1992 · 23 July 2002, 20:01

Could be, but the 030 needy demos will run much faster with an 060 beast

cv643d · 07 August 2002, 20:00

Hehe yeah true

Though its crazy that some demos wich are recomended to run on 060 are running choppy

(Thinking about the latest TBL demo)
