Paul,

Why buying faulty ICs? I can send you a bunch of faulty EPROMs and Z80 for your surgical procedure if you wish. Only postage you would pay. :lol:

Re: Yet another ROM adapter

What about buying a cheap IC, cracked up und pins reused?
To be honest I prefer to desolder the socket and solder the adapter directly to the PCB. :geek:

Re: Yet another ROM adapter

Yes Mark
You are absolutely right.
It's a solution to the problem which I wasn't aware of (the problem, not the solution :ugeek:)

Re: Yet another ROM adapter

If you are happy with desoldering the socket you can desolder the Adapter as well :mrgreen:

Re: Yet another ROM adapter

I would not agree that the soldering the adapter to the ZX81 board directly is the solution. In my opinion any modification should reversible as far as practically possible. I don't like any mods that require traces cutting, drilling additional holes, and so on. I've repaired a few boards (mainly Z...

Re: Another BASIC demo

The fastest version in Basic I know of is using a single print with a string variable containing all the characters of the screen. I used this to show a large walking man on the screen by 100 PRINT AT A, B;A$ 110 PRINT AT A, B;B$ ... 200 GOTO 100 this wasn't tested on a Zeddy so can contain errors. ...

Postage to UK is a very reasonable $2.33 - Probably as cheap or cheaper than buying a bulk lot and re posting within the UK.
Agreed.
Do you order one for me as well?

Re: Yet another ROM adapter

Yes. I'd like to have one as well.
If there were any more left I'd take the rest
You can send mine to Charlie, we will sort out the rest.
Kind regards Paul

Re: ZX80 3K Ram Pack memory

After some discussion with Charlie, finding the proper card edge connector with the long pins may be the biggest challenge with my re-creation project. Hopefully it won't be a show stopper, but so far my searches have not been fruitful. More searching to be done. Why do you need long pins? I have s...
