Has anyone ever heard of theProtec Microsystems PRO-83?

Hi Robert, Earlier this morning I was trying to program an AT90S1200 and got fed up reading the data sheets. I delving in my old box in search for my ZX80 spectrum and with it came out Protec Microsystems Pro 83 single board computer. The board is intact with eprom in place. One capacitor has come loose but it is easy to see where it has come off from, so I think it is fixable. The Pro-83 was given to me way back in 1983. I have never fired it up. I see on the casing the supply voltage is 9v and there is voltage regulator attached down stream. On the PCB near the regulator the manufacturer has printed +8 on the positive side. this is the best information I have. Have you powered your? and is it working. Please share any info that you have on this as I would like to fire it up one day. Regards Susantha Jayawardena Surrey UK
