Re: '81 keyboard error - all keys in columns 5&6 and below

Have you replaced the keyboard with a new one? You can get them on Sell My Retro for around a tenner.

As nobody else seems to be doing it, I'm considering supplying sets of the decals via sellmyretro in case other people want to finish off their ZX80 in the same way.

A rather good idea. My ‘80 is in lovely condition but I would buy a set as spares.

Re: ZX81 install new keyboard

All the modern ones do that in my experience (and I’ve fitted quite a few, from various suppliers).

One I’m currently selling:

Re: ZX21: CERAMIC RESONATOR

Good luck with the resonators. When I rebuilt a zeddy from scratch (viewtopic.php?p=27533#p27533) I had endless fun with them.

Re: ZX21: CERAMIC RESONATOR

From the top from a photo I took of a zeddy I desoldered and rebuilt:

Hopefully I counted the ULA pins numbers correctly.

Pretty sure looking at it the top pin is not connected. It looks like it in the photo but I think that is just a scratch.

Re: Spectrum 128K toastrack jail bars?

Thanks to (a lot of) assistance from Paul Farrow one cable delicately bodged modified and I have a great picture and full sound!

Wish I had found a longer cable for the MIC socket. Ah well, cable take 2 I guess.

Re: Spectrum 128K toastrack jail bars?

In the short term it turns out I can use my SpectraSCART with the toastrack and it produces a perfect picture.
It only produces beeper noises directly though so it looks like I need to enter the world of butchering modifying cables. :D

Re: Composite boards for sale.

Always interesting to see another comp mod board. It also always makes me wonder how Pokemon can do such a good board for so little!

Re: Attic 81's - My collection and attempts to repair

Mostly because I replace the regulators with these murata ones: https://retroleum.co.uk/spectrum-repairs-mods I’ve bought a few PSUs from here: https://www.oldskoolconsoles.com/product-page/power-supply Ask for the ...
