Yes. It was educational.

Don’t worry. Buying a ZX81 pretty much meant you didn’t have to talk to anyone for most of the 1980s.

Yes, it was an odd duck - and there was little point to it when the main focus was the Speccy. But it is a really nice wee computer.

On Saturday's stream I switched to ZX80 for one of the type ins but quickly became stuck. Done some digging and in the 4K ROM (the one I was using) those functions dont actually exist - only in the 8K ROM.. Problem there is we lose that pretty ZX80 font 😔

Alex Pretty, who was killed by federal officers.

I'm sitting here crying.

Watching the footage and reading the accounts of what happened to Alex Pretti has broken me...

Great review and demo of the @futurewas8bit.bsky.social SD2BBC.

I am going to claim full credit for the use of the RJ12 connector on the cable. That worked out really well, and as a bonus, the same cable can plug into a different adapter for the DE-9 userport connector on the BBC Master Compact.

It did but I still don’t see how your version would work. Try in a ZX81 emulator.

PRINT AT was a Sinclair BASIC thing; other BASICs probably did it in a different way.

I’m sure there is the possibility you could calculate every term in a nested loop in an alternative way using a bunch of extra maths, but why? It’s not going to be faster or more legible. Nothing in this code is printed more than it needs to be

Don’t think so.

QR Codes on the ZX81 My first job was as a support analyst at Xerox Brazil for their high-speed printers, the kind that you plug into a Bus and Tag interface to connect to an IBM mainframe. Their use varied from reports and code listings to bank checks and invoices printing.
