Re: 68K/OS "ROM" based disk attempt
Would doing a cartridge dump using FORMAT RAM1_MDV1 be possible? (assumes at least map is same as normal QL mdv.)

Re: Identity of PiHER 8C2K2 chip?
Surely nothing more than DIP resistor packs (pull ups?).

Re: CST Ram Plus eproms - CST QDisc v4 issue
I would at least try a logic probe on eprom select (pin 22 /OE) to see if after a reset it is at least polled to help start narrowing problem down.

Re: Announcing the new "Gold Card" - QIMSI Gold
Surely only by having a job running on BBQL to periodically copy 32K screen dump through FIFOs to QIMSI Gold

Gets even betterPeter wrote: ↑Sat Apr 27, 2024 1:11 pm You may have noticed 2 x 2 extra pins in addition to the QL ROM port (the smaller ones near to the edge).
One of them is leading QLNET and one is a "detection" pin.
The other two could be used with such a connector board. Possibly one as R/W and one as a chip select.

Re: FPGA replacment for the ZX8301 ULA and more
Oh I hadn't noticed the 68HC001FN16, so in the 8 bit data bus mode it provides the all important A0 for the QL (IIRC Gold card ingot has to deal with that).

Re: Announcing the new "Gold Card" - QIMSI Gold
Wow, that looks great. Like a QL compute module (conjures up a few ideas) 
An simple internal DIN41612 to ROMport connector board might be useful
