C64 PLA to ROM adapter
I have been looking at this project for a while and there are several boards around , however nobody has shared them so i decided to create my own.
For more information please see eslapions thread.

Thank you eslapion for all your hard work and insight.
The ROM is a 27c512 , however i am having some good results with eproms.
As people seem to be having trouble finding the file , you can download it here .
I will add more photo's as the project develops!

Once you have the parts together.
Start by inserting the pins into the socket like so:-
Then place the board on top with the writing upwards and the pins in the pins columns
with a gentle push the pins should go into the socket completely.
Then proceed to clip all the pins as close to the board as possible.
you can now solder all the pins.
Seperate the socket and place on top in the ROM columns keeping the notch on the socket in line with the notch on the picture on the board.
Turn it upside down and solder.
Then fit the capacitor and that is it Adapter Made.

Forget it. The "pla.901664-01.bin" on Zimmers.net is exactly the same of "906114-01.bin". It didn't work because I made a mistake, I used a 104 (100 nF) capacitor instead of the 68 pF as marked in the BOM (since I haven't a 68 pF, I used a 47 pF and it seems to work fine too).
I'm using an ST 27C512 -10F1 Eprom, just in case it could be useful for somebody
I have added a zipped file for download , Remember that not all roms work and yours might not be compatible with this hack . Hope you have what you need now. Alan Leverett
Very pleased to get the feedback , it is nice to know that it will work in some of the other commodore machines as well!
Ras is the one that tends to cause problems , cas is not delayed in the PLA.
