| Zenith Data Systems - Z-39 Terminal (1985) |

I got this terminal the same time as i got the icl terminal (i saved both of them from being thrown away, about 11 years ago), on the back of the terminal is two 25pin ports (one male and one female) plus one Rj11 socket for the keyboard, i think the two 25pin ports are serial ports (one for a printer and one for data), it powers on and shows a blinking cursor, an on-line timer and a keyboard error, but thats because i don't have a keyboard for it, so i can't properly test it out, i've tried to find out what the pins do and from what i can see, pin 1 = +12v, pin 2 = +5v, pin 3 = ??, pin 4 = ??, pin 5 = 0v, pin 6 = 0v, i tried connecting the keyboard from the icl terminal, the icl keyboard pins look to be, pin 1 = +12v, pin 2 = 0v, pin 3 = +5v (may also carry data), pin 4 = 0v, but when i connect up the icl keyboard, i just get some kind of data come up on the screen (still showing the keyboard error) but it just looks like garbage, i even tried connecting up an old pc keyboard, but again i only get garbage but this time it looks like binary, it might need some kind of serial/TTL keyboard or something like that, if anyone can help me out with this, i would be really grateful.

i thought you might like to see the computer (that i built about 3 years ago) that i use on a daily bases, it's a Pentium 4 @ 2.4GHz HT 800MHz FSB, 512MB DDR 400MHz RAM, 80Gig hard drive, MSI GeForce4 MX 440 64MB, for my main OS i use OpenSUSE 10.2 Linux. To make this site i use a PHP script i made to allow me to build this site by putting together all the parts of the site for me, i.e the top and bottom sections of the page plus all the middle parts in the right order and to upload everything by FTP.
