Thanks again - I see it is storing it in LAST_K but I do not have any change on the screen so I have to dig a little deeper. This is what the system variables look like:

A new ZX81 Emulator
Hello All, I am currently working on a ZX81 emulator with a twist. This one runs in on a Coleco Adam. I have a good chunk of it working, I get it up to the 'K" prompt but I am stuck with keyboard input. Since the Adam is a Z80 system with free RAM in the right area I am able to load the ZXROM at 0h,...

Looking for a printer
Looking for a working printer with a roll of paper for the ZX81 to complete my setup. Prefer a ZX81 branded one if possible - anyone have an extra for sale?

Re: T/S1000 Turbo Switch
Back in 2005 I did some testing on various ways of speeding up the TS1000: The program that I used for benchmarking the ZX81, TS1000, TS1500 and ZX81 emulator grew out of a conversation on the board about speeding up Sinclair Basic: 5 LET A=40 10 LET S=PEEK 16436+256*PEEK 16437 20 FOR K=1 TO 1000 40...

Why the difference in TV out port?
I have a USA version of the ZX81 (not the TS1000) and it has the TV out like the picture below but it also has a recess where you could remove the cut out for TV out closer to the EAR & MIC like the 2nd picture - why the difference?

ZX81 Letters
Has anyone repainted the ZX81 raised letters and the ZX81 16K RAM raised letters before? I have tried but I keep getting ink on the sides and it originally was only on the top of the letters.
