I always fancied a Sinclair QL back in 1984 I think when the adverts appeared but never got round to having one until now that it.
It’s a bit grubby and has a couple of keys missing and no PSU and no idea if it’ll even work.
I do know they need 9v DC and also 15VAC? Does anyone know if I can get it to boot with just the 9VDC? Guess I’ll find out shortly

Re: Sinclair QL - wanted one since 1984
Looking at the schematic, it should be safe.
The Microdrives won't run. I can't see +9V, +12V or -12V going to any of the main chips.

Re: Sinclair QL - wanted one since 1984
Thanks for the info @stephen_usher. I’ve done a bit of Googling and it looks like you need +12v for the video circuit? And as you say -12v for the micro drives.
I’m not too worried about this QL looking standard, so I’m going to see if I can make up a new PSU or maybe get a meanwell one that’ll do the +9, +12 and -12v required.
Can anyone spot a slight issue with the keyboard membrane? Nothing some scissors won’t cure.

A sucker for Sir Clive in a scarf, eh?
Looks a beaut. Good luck!
I know nought about using a QL but like the fact they had a better expansion system than all the 'wedge' ST range.

I feel the need for a purchase from RWAP Software via Sell-My-Retro or maybe eBay coming on. (Keyboard membrane)PhilC wrote: ↑Wed Jun 08, 2022 7:50 pm Thanks for the info @stephen_usher.
