Re: ZX-IDE Tutorial for programming assembler and ZX BASIC

Document formatted by application? RTF? Probably not DOC. I'll start looking.

It is not RTF, RTF does not appear to have binary headers.

Re: T/S1000 Turbo Switch

Is that "WhyWait" or "NoWait"? "WhyWait" is only 10% improvement. As Andy said, switching between 60Hz and 50Hz ... in real terms the speed increase up to 30% in SLOW mode. In the FAST mode it does not make any difference at all. If you are looking for a real speed-up solution, go for the modificati...

Re: Different ROMs for Lambda 8300

Sounds like someone with decent assembler skills would need to go after this one.

Addendum: The Futura 8300 was the unit for the U.S. so maybe it is built into the original ROM code/ULA to switch video?

Re: TI99/4A KEYBOARD ADAPTATION

Re: Different ROMs for Lambda 8300

Your Lambda is probably PAL?... and your ZX81 does PAL or NTSC based on... what is it PIN22 of the ULA? Using R30 pullup resistor? Lambda probably doesn't have that type of ULA...hmmm. ROM code changes on that maybe? https://k1.spdns.de/Vintage/Sinclair/80/Clones/Lambda%208300%2C%20Hong%20Kong/ROMs/...
