HEPAX-0C Prototype version ROM images.

Hi Steen,

Seems you've found the treasure chest! ;-)

I've noticed that the EPROM version in your (heck-of-a-breadboard) prototype is the "1B", seems that you kept using it after the first prototype chips from Fujisu were available.

Which is pretty reasonable at design stage since the breadboard allows full access to any point and signal while the (CPLD?) MB671209U is just a "black box".

BTW, if some spare MB671209U are still available I'd love to design a new PCB with some "improvements" (may be non-volatile RAM?) :-D

Look forward to seeing what other "jewels" you find inside the chest.

Best wishes from Canary Islands.

Diego.
