Re: Making Keyboard Membranes

It stared out as a conversation about replacing TRS80 CoCo membranes, and then branched into other old machines like the Mattel Aquarius. I'm not sure there's a huge demand, as someone had looked into it and was saying he couldn't offer them for less the $60 USD. I did run into one low cost alternat...

Re: Making Keyboard Membranes

I was actually looking to see if anyone had any information about, or experience with, making membranes... I have a number of retro machines for which no one's producing replacements, so I'm doing some research to see how feasible it would be to do runs of them.

Making Keyboard Membranes

I'm looking to make some keyboard membranes similar to the replacement that are available for the ZX 81's Spectrums. Does anyone have any advice, or the name of a good company to consider?

Shipping from the UK to the US

I wasn't sure where to ask this, so this ares looked close. Bit of an odd question, but I've bought a number of things from member of the forum in the past so I figured someone might know. Of those of you in the UK that have used Royal Mail to shipped items to US Postal Service Boxes, have you ever ...

You're not a salesman are you :lol: Mark Is that a statement or a question? :lol: ... either way I'll stick with (8 bit) masochist.

Re: ZX81/TS1000 and/or Spectrum?

I'm in the US as well, and I had been curious about the ZX Spectrum since I'd heard of them in the 80's. Finally got around to buying a few off of ebay, and several of the modern SD interface card... and all totaled, with the international shipping and PAL/RGB converters, it would have been about th...

Re: zx81 Keyboard...Sort of

I had the same idea and used those small clear cap keys mounted on a perf board. They're the right size to fit with in the ZX keyboard area, but the problem with the ones I recieved was that they had a lot rotational play in the key heads... They really twist around... Out of 100 switches a little m...

Save & Load Data

Maybe I'm thinking of another of my old rigs and/or SD interfaces, but I could have sworn there was a way on a ZX81, either from standard BASIC or with ZXpander, to SAVE/LOAD a variable to/from a file. It might be the method of getting the variables address and using the ZXpand's address range SAVE/...
