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.

Re: New release of EightyOne available
Just a quick one. Are there any plans for porting EO to macOS?

Re: Timex Sinclair 2068 faults
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.

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

Re: Timex Sinclair 2068 faults
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

Re: ZX81 rebuild
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.
