TF CD32 Riser Revision 2 Design Complete

[terriblefire]

I will fire over the CPLD firmware.. Its very basic and just passes PUNT via the CPLD at this stage.

Great.

What cpld do I need 144?
and if you had some time could you tell me what resistors I need to change/fit to get video out working?

CPLD is a XC9572VQ64

All the resistors that are there need to come off and 3 0R resistors need to go on.. i'll post a picture of what to change later.

I redone some stuff in amiga.c to make sure we don't miss any depressed keys. Works ok. I haven't noticed any issues on Doom or Pinball Dreams (and Amiga Test Kit)
Need to still test keyboard reset.

PS.
Code is dirty and inefficient, but works.

EDIT.
CPLD in place I even didn't know that I still have 4 spare ...
keyboard reset works ok.

I still haven't managed to crash either cd32 or ARM ...

Hi guys,

Will this riser support VGA out or "just" DB23?

Thank you

DB23 only.

I was on the fence for the VGA vs DB23 but most people just wanted DB23.

It would be the same thing at a signal level anyway.

By going with DB23, we then have to add a buffered RGB --> VGA adapter anyway.
Could buffers be added and then a VGA 15 pin connector be offered. Would save the need for an additional adapter....

It is open source project. Anyone can to modify it, if they wish.

Im considering a buffer anyway but i'm not going to do any converters. Too many things already on my plate.

Yeah I probably worded that poorly, I meant the buffers and 15 pin connector only...

I think given that i'm going to pull the video of EXT_A[RGB] it probably wise to buffer. What i'll end up with is buffered DB23 most likely.
