The Sinclair QL Forum

Hey all,

I picked up a Minerva+TKII EPROM adapter board from Chr$ and went to install it in my QL - it's an issue 5 board with the 2 JM EPROMS with the 74LS00 and the rats nest of wires going from the EPROM's to the 74LS00..

Have anyone fitted a replacement ROM board to an issue 5 QL like this? I'm not sure if I just need to remove the JM EPROMS, 74LS00 and the associated wiring and pop the adapter board in the left socket or?

Cheers,

KbJ

Lookup the AH section, should probably be the same with your JM.

Thanks! I'll go have a look.

Quick update...

SO removing the 74LS00, both JM EPROMS and the associated wires and re-installing the 0R links, it did the job. Thanks for the info!
