Hi,
I would like to no if there is a way to connect a serial terminal to a pc with this.
I t does have serial TTL output.
NZB80.html


And help or comments would be appreciated.

Hi that was a quick reply,
I do have the schmatic's for the NBZ80. My version of it comes with a 20mA current loop terminal.(Not sure what this is.?) And it shows a table with jummers for setting with TTY,RS232,TTL. Which one would I set it to.?
Kind regards
Vernon
I added another photo of a little bit on the schmatic.

The schematic explains everything. As does Table 8. Set the output to RS232 (jumpers 60-54-59) and if you're using a PC with a serial port as your terminal, connect the serial output from the PC to J5-18, the serial input to the PC to J5-5. The ground form the PC serial port should be connected to whatever pin (your clip doesn't show that part) to the GND on J5 (whatever pin that is). Your baud rate on the PC, as well as the number of data, parity and stop bits should match between the PC and your Z80 board.

You didn't say what you were using for a terminal, but the site http://pinouts.ru has the common serial port connections for various PCs.
 
It's interesting that you in NZ wound up with a fairly uncommon Italian-origin CPU. SGS, at least in the Z80 world, was pretty much unknown outside of Europe (and particularly Olivetti). You can easily find Z80s from SGS-Thomson from the merger with the French national company, but SGS itself was founded in 1957 by Adriano Olivetti himself.
 
My father used to work for a company in the late 70-80's and they did Olivetti typewriters and computers. I think it was my older brothers computer. Thats how I ended up with it. I'm happy it still goes.
 
Wow .. that's the first time I see one "for real", I remember seeing photos of it when I was reading some books like "Programming the Z80" and such.

SGS I can't even remember all the various "transformations", I think the one doing electronic components ( chips ) now is called "ST" and is a merge between SGS and Thomsons electronics, I remember vaguely something like SGS-Ates can't remember what components we were using of them.

Z80 ( and 6502 ) stuff is almost "unbreakeable", it always works :)
