Re: ZX80 3K Ram Pack memory
Mark, thanks for the suggestions. None of the chips are socketed, but having received a new batch of 2114's in today was planning on doing a little soldering this evening. Instead, I will follow your plan and see what happens, taking it one step at a time. Will first install the capacitors and the e...

Re: ZX80 3K Ram Pack memory
Thanks for getting back to me Mark. Unless I just don't know what to look for ( a distinct possibility) there does not appear to be anything going to 23B on the Brenner design I am using. Take a look below and see if that is correct.

Re: ZX Printer Belt
The 0.01" music wire has arrived, and have done the measurements of the stylus. Will hopefully get a couple of prototypes done this evening.

Re: ZX80 3K Ram Pack memory
Will do, Paul, and thanks for the 4K reminder. The SMR listing has been updated.Hi Mike, I had to search a while. Would you be so kind to also list it in the ZX80 section?
And it extends the internal ram by up to 3 k giving a total of 2 to 4 k of RAM.
Thanks,
Mike

Re: ZX Printer Belt
Man, that is great to see! And I thought I had your only stylus. Please send a close-up of how you attached them to the posts.
Without your generous help it couldn't have happened!

Re: ZX Printer Belt
Great looking belt! I really like the way the teeth fit. Good to know that about cleaning.

Re: ZX Printer Belt
Thanks for pitching in, Moggy. Since I have Francois' styli held captive for the moment we'll have to wait until I get them back to him before a real test can commence. I searched for hours to find the .016" music wire that came in and it is noticeably thicker than the wire used on the stylus. Not o...

Re: Sinclair ZX80 Computer / collectable item with 16k RAM adaptor On Ebay
Was that RAM pack actually available at the time of the ZX80?

Re: ZX Printer Belt
That is great news, especially the fit of the teeth in the sprocket grooves. I couldn't have gotten them that close without the actual pieces you sent. As for not having the styli attached during your test, I would suspect that the printer doesn't know (or care) whether they are there or not. With t...
