Re: Zx81 from death to life??

RS232, You gave your ZX81 a complicated and hard life. :o WOW! Keep it simple, s______ by gutting a RF modulator's innard. And put a very cute little circuit board inside the metal box.

Re: NOOO.. My just arrived TS 1500 is flakey!

Hello diskman,

I am also a American. How does your TS1500's voltages read? There are soldered 8 DRAMs inside the TS1500. These DRAMs demand GROUND, +5 VDC, -5 VDC and also +12 VDC. If not, then check these electrolytic capacitors.

Have a nice day.

Cheers,

I still have that device with its clear plastic box, its assembly instruction paper and its loading/saving instruction sheet.

Re: ZX81 - White Screen No Cursor

Check for a potential "missing" jumper around LK1. :?: I clearly understand that your motherboard has its 1k (2) RAM chips. Thank you for the picture of your board.

Re: New release of EightyOne available

Does the EightyOne have its own assembler section or program?
