Hi,
great work, thank you.
I would like to give it a try for my own 65C02 homebrew computer I‘m about to assemble.

But I‘m a bit lost regarding the EPM7128.
Would you please explain how to program the „Altera EPM7128 CPLD“ chip?
There are 3 files in folder VHDL. I guess thats the firmware!?
But what device to use to get this firmware on the chip? I own a xgeco t48 eeprom programmer but EPM7128 is not on the supported devices list.

Do you have any advice?
Best regards
Udo

Hi @uesser

The files in the repo are the source files only, the .jed is not included - but I will build it and add to the repository

Programming the CPLD can only be done via JTAG, the easiest way is to get a cheap Altera Blaster clone on eBay and use Quartus to program the CPLD

The version of Quartus needed is 13.0sp1 which can be found here but I don't know if it works on recent windows versions

Thanks a lot.
I already saw an USB Waveshare blaster on Amazon but was not sure if it is the right tool. It is a JTAG blaster and supports, among others, MAX7000.

Again, thank you very much.
