Sinclair ZX80 / ZX81 / Z88 Forums

Yeap,

To be honest you need 3 wires only. A10 line is connected via L2 (link) to the new memory chip.



And don't forget about 10k resistor between pins 27 & 28.

Good work! I like happy endings.

Just a quick one. Are there any plans for porting EO to macOS?

Having some experience with TS2068 I would also recommend a full recap of any electrolytic caps. With my TS2068 I was fighting with wash out colours and after recap they were back to NTSC normal. I would not worry about tantalum one as this type can last forever.

$15 for the belt with styli is very good price. I would be interested in 2-3 units.

Thanks for sharing. I like it and other old fashion games from the link.

For Timex Sinclair 2068 you should use a 15Vdc/1A power supply, 9V supply is too low.

Hi Mark

Now you can laugh out loud, because Lardo asked me for a faulty unit

Good work.

BTW I’ve got a few RF modulators in my spare parts drawer. Some of them should work fine, the others are broken. If you need one drop me a line.

Yes, 3 sets were listed for sale there.

No, just normal video output. See below.
