Regards,

Here are the files for the Keyboard PS/2 hack, it includes the source and can be used to fix the rev5 riser.

Please read the readme file.
Many thanks to Solo761

Hells yeah, thanks!
I'll have to bother you some more after I am done, because I'll need a PIC :P
Or are there any services that sell pre-programmed PICs like there are fr EPROMs?

Tried to get that file, I got an error: Not Found [CFN #0005]

Really appreciate the files mate, regarding schematic to wire her up to a cd32 edge connector do you have that handy? or will that be released soon

Best regards,
Chris.

i will put that up later, the cd32 expansion header info is on google if you want to prelook. there are very few connctions

I will post the gerbers once i get the final boards in, i made a change to the height so i need to verify i never screwed it up

Can somebody post an image of that diagram? I don't have Eagle and I will not start having it now since it's not of my interest.

Plain old schematic as an image with connection names would be enough. I can map out the rest, since I am doing it all on my own anyway.

Also would help to know how the current one is wired on this board kipper, sorry man, just trying to get this so I can fix it myself, and I believe I am not the only one. I am sure some of this is already implemented in the board and I have a socket there of which I can use 8 pins to connect to an intermediary home made veroboard thing hosting the 16 pin PIC.

The readme doesn't even have the BOM so I have no idea if this is just straight wiring or i I need components that might already be on the riser board.

Throw us a bone kipper, it's not like we are sending this shit back to you to bother you more. We just want to fix it ourselves, but we need proper instructions for people who don't delve into board design (ie we don;'t have EAGLE, we need images)

@brian

I really appreciate your efforts here my friend, honestly!

@akira
If you get it working pal let me know, I'd like to make a solder-over solution to the back of any riser board inc my own board. (for reference to my idea: http://1.bp.blogspot.com/-WFW0QNuQps...oFixes%2B9.jpg )

Yeah that sounds great! The thing is, this riser already has some of this mod done I believe, and wired to the 8 pins of the bad PIC, so I would like to try to fix it that way, but if you make a solution that just works by doing what is shown in the pic, it'd be rad, especially if you add more features.

But the solution I want to reach here can be done at home with veroboard without the need to etch a PCB!

here are the pins...

Looking at the 182 pin CD32 riser. you can see what pin numbers are by looking at the numbering sequence.


chip pin 2 (KBDAT) = riser pin 122
chip pin 3 (KBCLK) = riser pin 121
chip pin 5 (GRound) = riser pin 9 (lots of other choices)
chip pin 6 (PCDAT) = goes to mini din plug
chip pin 7 (PCCLK) = goes to mini din plug pin
chip pin 8 (KBDAT) = riser pin 120
chip pin 14 (VCC) = riser pin 80 (also a few choices)

use the diagrams in the zip for minidin plug pinout

Well just placed an order at UTSource, hopefully get building these TF328's and the TF530's I bought from you next week?
Also grabbed 10 XC95144XL for any further models you produce.

@brian you're a legend mate thank you

@akira Yeah that's the plan, as soon as my riser comes from china I will be turning her behind into some kind of Frankenstein's wife before committing it to a PCB amongst other features.

@plasmab will be interesting to see how much they go for, good luck with the sales

I was looking at what it cost me and I was thinking around Ģ45 per gold board for ISSI ram and Ģ35 with Samsung RAM. Realistically i'm just getting the money back for some stock at that but I was hoping to put the money towards a Cam for my new AmScope...

Just wanted to check on the boards' i've shipped. is everyone happy with the packaging and speed of delivery? Any issues message me on eBay.

Although Iīve already bought the boards from your eBay sale itīs very tempting to own complete TF328 made by its designer. Hopefully, Iīll be fast enough to get one.

I'll do the complete boards on amibay. Low enough volumes for that.

@plasmab packaging and delivery were fine for the 2 cards mate. As for that price, that's a really fair price and I doubt anyone would complain about it.

i made a wee mistake, thats what i get for copy pasting...

chip pin 2 (KBDAT) = riser pin 122

chip pin 5 (GRound) = riser pin 9 (lots of other choices)
chip pin 6 (PCDAT) = goes to mini din plug
chip pin 7 (PCCLK) = goes to mini din plug pin
chip pin 8 (AKEYRESET) = riser pin 118
chip pin 14 (VCC) = riser pin 80 (also a few choices)

use the diagrams in the zip for minidin plug pinout


here is the picture to show where to insert the diodes (3 required), cathode (white line) closest to the RAM. cut and insert the diode where i marked with yellow circle.

Before someone corrects me, you can simply cut the track in the left hand circle as power is coming in from the top right.


Edit, i cleaned it up a bit. Red lines indicate traces on top, Blue on the bottom



In theory, any future updates of this board can have a 0 ohm resistor on the main 5v rail for those boards that require it for 5v ram, and you could swap out the 0 ohm resistor for a diode for those boards using 3.3v ram as the remainder of the board uses 3.3v. I think the CF card would get along fine with 4.6v
