Recreating the Ferguson Big Board

Speaking of floppies...finished up my custom Flash Floppy compatible PCB that plugs directly into the the Big Board's floppy port last night. Details on how to build your own are at https://github.com/djtersteegc/OpenFlops-Ferguson and also linked in the main reproduction repo's README. Now that I've reduced my workbench clutter (sounds like a good excuse) when using these boards, I can finally build and release the v1.1 board design. :)

Sure looks like the SWP board. If so, it should be supported by the "SmartROM" by MICROCode Consulting, https://www.microcodeconsulting.com/z80/smartrom.htm

I can copy/duplicate the PROM and one of those cute TTL testers should identify the IC's (or confirm they are the same as Enrico's pic). I about 10 spare FD1791's here too which should be 8876A compatible.

Finding bios source might be a bit tougher!

Could you please send me a message? I have a few eprom questions for an mc68hc711
 
Hey, got any of those OpenFlops-Ferguson boards left? I'd like to have one for my beloved BigBoard.

Nevermind that request, I've made a few changes to the PCB layout (mainly to replace the unobtainium SD card socket) and am ordering some. Thanks anyway, though.
