Re: Power Supply switching between ZX81 & Speccy

Composite mod with a 100uf cap in the circuit :) I've just had a tip on WOS to replace TR1 & 2, and install some 1uf caps in C5-8 to reduce the effects of the crawl, and will see whether it dwindles sufficiently when that's done ;)

Re: Power Supply switching between ZX81 & Speccy

Interesting stuff... well hopefully our computer room won't have any massive shifts in temperature or humidity like you describe ;)

Kind of like formation dancing of ants on the screen. Is that what people mean when they say "dot crawl"?

Re: Power Supply switching between ZX81 & Speccy

:? Deep joy :roll: The Speccy is completely re-capped now, and working well, apart from a little shifting interference on the screen when I'm processing summit. I'll bear in mind the gold-plated thing, but I thought that gold-plated was the bee's testiclons? Why is everyone going on about how good i...

Re: Re-capping a ZX81

I've done the Speccy, some of which were looking a little "iffy", and last night I even re-capped the old logic board out of my fridge freezer while I was replacing some blown components after it failed a few years back. Long story. :roll: I've got three 16k RAM packs to my name, one being the Memot...

Re-capping a ZX81

I've just finished a re-capping frenzy on my Speccy and Amiga, and was considering it for the Issue 3 Zed, but wanted to ask whether there are any issues to be aware of when re-capping one. There aren't a great many caps on board, so if I have to buy some in, I might try & get radials, as I don't li...

Re: Power Supply switching between ZX81 & Speccy

:lol: ok... I will try. There's not much more I can do to the Zed now, but I'm currently girding up my loins to tackle the re-cap of my Speccy. I did my A1200 last night, which was quite fraught, mainly because most of the caps were SMDs and they were leaking, so I lost a couple of pads and had to b...

Re: Power Supply switching between ZX81 & Speccy

I tested the lead with a multi-meter before trying it live, and you'll be apathetic to know that it works just fine http://www.britmodeller.com/forums/public/style_emoticons/default/yahoo.gif The new plug on the Speccy lead also fixed its random resetting/going off problems http://www.britmodeller.c...

Re: Power Supply switching between ZX81 & Speccy

Job done. Immitation is the sincerest form of flattery ;)

Shame I couldn't get a gold plated socket, but as I had 20 of them in stock, it would have been churlish to order another 1-5 just for the gold plating :ugeek:
