The 6525 would be very straight forward, you could also do it using a schematic as entry as it's latches and buffers. The tools are all free, I switched from Xylinx to Altera many years ago, and the there are relatively cheap dev boards, from $70-$200 that can have a general purpose I/O breakout. -----Original Message----- From: email@example.com [mailto:firstname.lastname@example.org] On Behalf Of Michal Pleban Sent: Monday, April 23, 2012 3:38 AM To: email@example.com Subject: Re: FPGA (was: 6809 / 6702 puzzle) Hello!

What about a board with the most > common ICs and a FPGA/CPLD covering the glue logic and the 6525? Well, the 6525 chip is also rather hard to get nowadays. It would be much better to have it on FPGA than to hunt for old CDTV or 1551 machines to cannibalize them... I guess there is no available 6525 core to reuse. Maybe I should go back to my long-forgotten Verilog skills and create one? ;-) Regards, Michau.
