Thanks to our member Suzy for designing and making this new coreboard available. Suitable for both standard and premium PC85 Microbee. Basically it can now handle 128 PAK locations (0 to 127) compared to the original 16 only and now used 16 x 27512 eproms, so that means lots of games My SRAM hasntt arrived yet, so I just used some old PC Cache ram that was physically the same size but larger capacity.
Burnt out a couple of Basic 5.29e eproms as I'm using a Premium baseboard. Powered it up and bingo, boots to Basic
The board so far looks like
and when powered up, I get to Basic as no other EPROMS fitted yet, thats the next job to write up a Menu and start creating some Games roms.
