Re: Today…

Peter, Derek, for SMSQMulator, its most probably pretty straightforward. For uqlx, it might be a bit more tricky, if not impossible. uqlx doesn't support SMSQ/E, so you might (most probably: will) run into a lot of tiny incompatibilities between SMSQ/E SBASIC and Minerva SuperBASIC (you will need to...

Re: QL USB Keyboard Conversion Kit

I tend to go the other way and use PS/2 keyboards for use with some of my retro computers... I do so as well. Torturing yourself with a non-optimal keyboard is all-right if everything is original. But I really don't see the point doing that when modern hardware is involved.... I normally type a lot...

Re: Identifying a QL disk interface

I didn't realise that Sandy released just a bare disk interface (with parallel port). http://www.rwapadventures.com/ql_wiki/index.php?title=Sandy%20Super%20Disk&lang=en :D The SuperQBoard version 2 was apparently produced in a severely downgraded (crippled?) version only partially populated as ...

Re: Identifying a QL disk interface

There were, as far as I know, 2 revisions of the SQB - I used to have an earlier one, that was as described above (large heatsink along the DIN connector). The mouse one (that I never had) apparently had a memory daughterboard. In this case it must be one of the later "SuperDisk" boards be...

Re: Identifying a QL disk interface

No Sandy board, IMHO.
The SuperQBoard had the 7805 + long aluminium heat sink towards the QL end.
Apparently, there's also a parallel port and no memory expansion (and no connectors to an optional memory expansion that later SuperQBoards used to have)

Re: SERial line reset

Maybe I didn't make myself clear enough: <CTRL><ALT>7 does re-set the IPC. But as the communication between IPC and "main" QL is in no way secured and breaks as soon as one of the two partners is not compliant with it (which happens if the IPC stops to transmit in the middle of a transfer ...

Re: SERial line reset

Not to my knowledge. You can press <CTRL><ALT>7 , that will reset the 8049. But also resets (and thus, confuses) all comms with the IPC, so it's not really useful because it will also kill your keyboard normally. If all channels to the serial ports are closed and it still doesn't work, I'm afraid yo...

Re: SimSER SRX not working on BBQL

Martyn, the fact that you get some bytes across when opening and closing the channel on the receiving end hints - to a misconfigured cable. Opening and closing the channel will toggle DTR - If this is connected to CTS on the PC end instead to DSR where it belongs, you'd see exactly the effect you ar...

Re: DOM

Yes, as Peter has pointed out, DOMs normally have a non-standard IDE connection that connects them to +5V. The QubIDE re-make supports that. If you want to connect the DOM to a PC, however, you will usually need a separate Power Supply - Normal USB-IDE adaptors do not normally supply the DOM on this...
