My name is Eric Johnson and I recently joined this group. I'm
interested in hearing a little more detail on your cartridge ideas.
Back in the 80s I did extensive modifications to Larken, Oliger,
Orfelt and other cartridge boards. I added a 32k static ram to a
Larken cartridge and was able to load the Spectrum Emulator or OS64
Opsys from disc by shadowing between the upper 32k or Exrom bank and
the lower 32 k of the dock bank. I then made it logically
(hardware) writeonly to exrom and readonly in Dock. I have a piece
of rare hardware in my collection. A virgin 128k memory board from
Tom Bent. This is a bare board that has never been populated. If
your interested I'll tell you about the other goodies in my stock.
