I think it's quite important that you power them up occasionally, and kick the tyres, so to speak Tony or Nasta may chime in here, but I believe there are electrolytic capacitors on the QL board, and these don't age very well if they're not used I believe [my brother told me - I'm a mathematician] summat like the chip doping [also] goesI've got a StarChess machine that takes ages to warm up, and it hasn't got a single valve - thanks for the reminder, must go and power it up; interesting smell arising from it, but at least it's still working

Hello Steven, I wonder how many more of us are lurking on this list and only occasionally putting our heads above the parapet? I am sorry that the repair wasn't reliable. If you send it back I will either fix it, replace it, or give you a refund. I still have some spares somewhere. I am attaching a Zip file for general information which contains what I have found so far of my superQboard files. They are all ASCI files for viewing in a QDOS window, but WordPad in Windows seems to handle the formatting OK. Just a note to Nasta to confirm that I have sent the files he wanted. Best wishes to all, Keith. (Drops head down below parapet!) sQb.zip Description: Zip archive

Re: [ql-users] SuperQ Board
There were two types of mouse interface... One was a 9 pin serial mouse, and the other was a DIN socket that also used a serial mouse, but I don't have the pinout. I recall most were the 9 pin connectors. I don't recommend using one in an In Car Entertainment Ssstem ;) Dave On Wed, 27 Feb 2002, Phoebus R.

Does the US QL have any hardware differences, or just OS differences and a different modulator? Dave ql.spodmail.com

Hard to imagine that they would do serial mouse protocol to QIMI register translation in hardware. Bye Richard

I haven't even seen an SQB in 15 years :o( QIMI rings bells too. Dave ql.spodmail.com Nasta is right. The SuperQ Board mouse was an Atari type just like the QIMI, but with rearranged pin connections on the 9 pin D type plug/socket.
