OK, so an old guy dropped off a box of "computer stuff" as a donation at our front desk (I work for a charity). In the box there are an assortment of components, some Veroboard and stuff like that. There were also three Sinclair QL computers and a further two in pieces with evidence of modding/tinkering, along with a bunch of QL ROM cartridges and an unknown card hanging out of the expansion port of one of the complete QLs, picture below. insert standard potato pic apology I played with QLs at school and "inherited" a dead one from a family friend, but I never owned a working one. Can anyone Identify the card in the pic and does any body have a old/spare QL PSU I can buy/borrow? I'm guessing it's a IO card for a drive. One of the dismantled QLs has a weird, possibly homebrew, floppy drive with a 2.5" HDD slung underneath. I want to test these machines before I send them to our ebay centre for listing but, if they don't work they get binned unless I send them as spare repairs, which means they get listed for pennies as a job lot. The incredibly flawed logic of our ebay hub doesn't allow for listing as spares unless we specifically state it and there's no option of and/or with them. i.e. you can't send something and ask them to list it as spares if it turns out to be dead when they test it. Don't get me started - I recently sent them a virtual presence robot as spares/repairs because I couldn't source a power supply to test it. I want to maximise what these will earn for the charity, so I often have to jump through a few hoops to achieve that. I'll tag @Gareth Halfacree just in case he can drop some knowledge, but I really need a PSU, if anyone can help. Cheers all.
