The Sinclair QL Forum

On offer here are 2 sort-of working QLs. Sort of, due mainly to non functioning microdrives. Both are in used condition but cosmetically generally ok with all keys present. No. 1 is an issue 5 PCB with serial D09-024322 (with the socket for a 74LS00, so a bit more flexible with EPROM usage - if you ...

Bother. Chr$'s XBAD03 image is the same as mine, suggesting that there's another fault on the OPD causing Housekeeping to crash when attempting to format a cart. I remember being able to format a cart, but it was with my main OPD with a different set of ROMs.... the ones I dumped were from a spare ...

My XBAD03 ROM, and the others are in this zip file.

The other zip file is the phrase ROM that I captured using a BBC B.

Thanks Tony. Yes, it's 'fast' RAM. I hope your Trump card works (no reason it shouldn't, they are quite reliable).

You won't need the 5v on the 12v line. And one ground should be enough (use the one next to the 5v).

Worth more than £100 Derek. I'd buy all you have for £100 each! It's subjective of course and there are a few factors (like any thing old and offered for sale).

Next week I will finish making the programming adapters, then I can try both my bad board and the new one with existing and newly programmed chips. T...

I'd never seen one for sale in the last 5 years, until that recent one on UK eBay for which the seller is asking really silly money despite it being untested It's dropped to £800 now... Think it was already down to £800, then he/she put it up again. Rare item no doubt, but I can't see it being in t...

I have the following available. Disclaimer: You know how it is with 40 year old mdv carts and reliability - they might work for 5 minutes or 5 years or they may not even make it fully working on arrival! I will test all of them before I send anything and will liaise with perspective buyers. I can po...

I was very happy to pay €65 + postage for mine. It's worth double that for the convenience! Which is just as well, as I'm about to pay €65 + postage again, for another QIMSI after trying to make a vacuum formed housing for it and breaking it in the process. Then making it even worse be attempting to...
