If you really need to use a pure USB keyboard (for a wired keyboard you probably don't) it is better to use an active USB-PS/2 adaptor.

I haven't all the posts but could it be possible to use your PCB and design an adapter board with the socket for CPU and 8301 routed to a DIN41612, this instead of having to reroute the PCB? This can make sense for just two or three boards. But if a little series production is intended, I would not...

PCEN peripheral chip enable. Surely any ZX8301 replacement will need to provide it for ZX8302 on pre issue 6 QLs (also TXOE). Thanks, I forgot and just looked at the issue 6 schematics. Pity an expansion port solution fails just because of that. Another thought might be whether the ZX8301 needs to ...

Not obvious to me why you'd need that.

As the SD card is not accessible, I wouldn't see the internal QL version as self-contained. With the QL case closed, one requires a PC and Wifi connection to exchange data. Sure. And what do you use to write/read to/from SD cards? QL and QL and Q68 and Q60. The SD card works as a removable medium b...

For the QL, there's also an internal version (again self-contained). As the SD card is not accessible, I wouldn't see the internal QL version as self-contained. With the QL case closed, one requires a PC and Wifi connection to exchange data. Nice for those who prefer remote-controlled retro-computi...

And also this way it works also as a ULA replacement (I mean without the need of a ULA). Can't remember the details of your ever-changing projects, but you seemed to have your own RAM on this one. So I can't see why the board needs to sit in the ULA socket to replace it. RGB and the SYNC signals ar...

If you prefer an internal reader and have no interest in a mouse port, then QL-SD is also a nice option.
QL-SD is just no longer made, so you'd need to find it second hand.

If I understand correctly... ...the board uses an add-on at the expansion port space to bring out connectors ...the board does not work with other cards at the expansion port anyway ...there are concerns about internal mounting with lots of socket contacts Which makes me question why it does not sit...
