Looking for a printer

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?

ZX81 Letters

Re: Hello again

I have a Zx81 with 16K on its way to me - supposed to be USA version - so should I expect it to be 60 frames and 2K or? Also I will want to make the composite video conversion soon after receiving so can someone point me to the very easiest way of doing such?

Well that kinda sucks but I guess it makes sense if you are only saving the sound and not caring about the content. :(
