Sinclair ZX80 / ZX81 / Z88 Forums

Welcome to the jungle.

So are regulated the same as switching? If not are the methods of controlling voltage the same?

I noticed the original is better resolution. I shouldn't have placed inline. Maybe this one is better. Remove ".txt"

Found this.

That is the issue. I used the PSU that was in the original box without checking that it was the right one. Now no telling since it probably was the wrong one, unless I misplaced it. So far nothing that I have is 15V and still looking.

Maybe why it was inconsistent. I believed I used a 12V PSU.

I was getting ready to wash in the dishwasher or replace all the caps.

Fixes Apple Macintosh boards from cap leakage. See YT videos.

Keeping in mind that the units have both a RF and a composite output, and that I used the same power supply. TS-2068-ONE has no color but does black and white cartridges just fine. TS-2068-TWO shows vertical bars and other video failure symptoms. Checking for the powersupply: http://www.old-computer...

It will be a great knock-off. I wanted to make a similar case for a ZX81 and an enlarged membrane keyboard. It was around $1000 for minimum quantity of membranes from the suppliers I found.

Of course! Do what works for you... I, for what it counts, like this method.

I have seen this in U.S. (SOME) coding if I am not mistaken. Also with Linux bash scripts.

If your working on a team though, they might squeal!!

Both of mine have video problems...caps?
