Not really a PIC topic. > a whole bunch of intel chips - 8085, 8255, 8155H-2 8253-5 CPU, 3 port IO, ram+(ep)rom, timer. This is the Intel chip family that powered the Mars Rover vehicle. It is totally obsolete except as spare parts for medical and other equipment that uses it (the 8085 is certified for this, many other cpus are not afaik). Assemblers etc for this are still available. You can probably work out the interface and use the printer as is for something (like driving a simple CNC machine which you get to build - you already have steppers, drivers, a parallel interface (or is it serial ?) etc). It could be a long but rewarding learning project imho. At least that's what I'd do with it if I'd have the time ;-) Peter -- http://www.piclist.com#nomail Going offline?
