Sinclair ZX80 / ZX81 / Z88 Forums

All,

I found what I believe is a USB to TTL Serial cable (6 pin colored) cable for a past micro-controller project (5vdc).

This should be the connections: (EDITED in CODE window)

I'm hoping I can use the new SERIAL command and baudrate to use HyperTerminal or something to communicate to the ZX81/TS100 and also the Parallax Serial LCD I will connect to the IDC connector on the ZXPand+

Interesting test. My ZXPand+ should arrive any day now.

Tim, the forum software makes a mess of tables, so put your tables in a "code" box (the </> icon above the edit box) like so...
Note you do still have to play with the spaces a bit...

Perfect. That's a FTDI USBSerialTTL that is. I have a couple. Great kit. It's the same pinout as my 'super serial' board that is on GitHub if you care to peruse
