Surprisingly, my lower offer for this computer was accepted. I now have a "Rare Motorola 6800 EXORbus? System Micromedic MACC II Assay Compucenter Boots Up" Might be Motorola Exorbus system but that's not important. I'm pretty sure I can run Flex and that the 'Boots Up" is the Motorola MIKBUG rom monitor prompt. I see 4 serial ports (RSR232, current loop and parallel port). I need a bit of info on the keyboard. It appears to be a serial keyboard. Since I don't have one I expect I can build something that sends ASCII at 110 or 300 and it will work. If not, I disassemble the 2716 (5V). I'm good with that. Any ideas? BTW, the Micromedic MACC II Assay Compucenter interfaced to Nuclear Medicine test equipment. -- Linux Home Automation Neil Cherry kd2zrq@linuxha.com http://www.linuxha.com/ Main site http://linuxha.blogspot.com/ My HA Blog Author of: Linux Smart Homes For Dummies KD2ZRQ
