Re: The Sinclair ZX80/81 and TS1000 taught more efficient programming

I agree. I wrote some very good 1k games in BASIC on the ZX81 (I wish I had them now, but they were lost years ago) and it did encourage you to write efficient code. Biggest problem with the C64 was the BASIC was far too primitive considering the advanced capabilities of the machine. To do anything ...

Re: Hello from the Netherlands..

To be honest I like dot-crawl on the speccy from a nostalgia point of view, as all the speccys I used back in the day had that, so it feels like genuinely part of the experience. I also use my ZX81 and Speccy on old CRT TV, as I feel LCDs pictures can be too sharp and clean. Nice to know there's a s...

Issue 1 ZX81, some keys not working - keyboard looks ok, also RAM packs don't work

Hi, I've got a rather battered Issue 1 ZX81 that I'm considering restoring (I already have another fully-refurbed one I bought from Ebay) It powers up OK, but some keys don't work - HJKL and NEWLINE. I opened it up and checked the keyboard connectors and they look ok - no obvious breaks, so I'm not ...

In my defence it was an auction and nobody else bid!
You're lucky, every one I bid on had loads of other bidders. I eventually managed to get a fully refurbed one for a bit more than I wished to pay, but it's a lovely machine and I've been having great fun re-living the old days.

Re: Lardo buys another zeddy

Ah so you're the one who was buying up all the ZX81's on Ebay and making it hard for me to get a decent one. :roll: :mrgreen:

Hello!

Hi, I first got a ZX81 in 82 or thereabouts. I wanted a Spectrum, as that was due to be released, but I just couldn't afford it, being 16 years old, in sixth Form, and my family couldn't afforded to buy me one. So I scrimped and saved and bought a ZX81from WH Smiths, and taught myself BASIC programm...

Re: ZX81 with vLA81 and composite mod has black screen while loading

Wow! That Chroma interface looks amazing. Unfortunately it's sold out otherwise I'd be buying one right now.

Thanks for the info. I'll keep looking out to see when it becomes available.

Re: ZX81 with vLA81 and composite mod has black screen while loading

Thanks for the quick reply. What confuses me is that an old analogue composite video monitor from 1984 doesn't display a proper picture while loading either. I'd have thought that this would work as it doesn't have any fancy signal processing. I've not seen any mention of this issue anywhere else. I...

ZX81 with vLA81 and composite mod has black screen while loading

Hi, I recently bought a reburbished ZX81 which has the vLA81 modern ULA replacement, 32K RAM and a composite mod. Now I'm really happy with this as it mostly works great, and I've had a lot of fun playing all the old games I played as a teenager, and typing in some programs for fun. With the composi...
