Hi Noel, >> Any chance it could be put into 'production'? Sure, if there is interest, I could make a run of boards.
>> Also, what FPGA board are you using? I assume it's one that has an SD >> card socket or something, for actually storing the bits on? My project is just an interface board for an existing RL02 emulator project: www.pdp11gy.com There are a multiple project revisions listed on the pdp11gy.com site that use different Altera FPGA dev boards: DE0 Nano, DE0 Nano SOC, and BeMicro CV. I was planning to use a Terasic DE0 Nano dev board since these boards can be found on eBay from $50 to $100. The DE0 nano does not have an micro-SD card socket which is why there is a socket on my interface board. http://sierracircuitdesign.ddns.net/temp/RL02 The DE0 Nano SOC, and BeMicro CV dev boards have micro-SD card sockets, so if you used one of those, then you would not need to populate the micro-SD socket on the interface board. According to the author of the www.pdp11gy.com RL02 project, the 40-pin headers on DE0 Nano, DE0 Nano SOC, and BeMicro CV are compatible, so you could use my interface board with any of these boards.
