Re: Hello again

I got my ZX81 USA today - from the son of the original owner. Complete (except missing box) and works great.

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?

Re: ZX81CRSS.ASM

I wonder if it will be possible to put the 10 line (RAND USR) in the printer buffer, and assign the NXT_line to the prt buffer!
