First power up

Postby wmh71 » Wed Mar 20, 2019 1:00 pm

Hello, just got my hands on a ql and it’s been in a damp, cold shed for a few years. What do I need to before powering it up? And what checks etc I should do?
Many thanks

I think I would open it up and check the condition inside. Check for git big spiddas and corrosion etc. But, opening the case will probably finish off the old keyboard membrane (if it was still working).

Put it in a dry and warm place for a week, then simply power it on. (At least if it doesn't rattle when shaken)

If it works after the first 10 seconds, fine (it probably won't completely work).

If it doesn't, quickly switch it off, then come back to us for tips on repair.

There are computers out there that are known to literally self-destruct when faulty (like the ZX Spectrum). My recommendation would absolutely not be valid for those. But the QL has no such intricate circuitry in there - It either works or doesn't, in my experience.

As VP said, the keyboard membranes are becoming brittle with age - Opening the computer can do more harm than good on them. Apart from the membranes, QLs are a pretty sturdy kit.

Thanks Tobias,
That’s really helpful. If you hear a loud bang, you’ll know things didn’t go to plan :(

I usually get someone else to turn them on, while I stand in the corner with my hands over my ears >_<

I 100% back Tobias here.

Do you plan to use a monitor or plug it into a TV? If a TV, will you use UHF aerial cable or a SCART lead?

Tv at first, I have a few spectrum Aerial cables, so assume they will do? If not I have a monitor, but it has a video input so not sure if I can get an adapter for it. Can they have a composite mod done like the spectrums? Thanks

I don't know what this composite mod is, but they have colour and mono composite available on the RGB socket.
