Last week i had to fix a cut and bend machine of that kind ( essentially it cuts steel sheets to a specific lenght with a guillotine and bends it into shape with an hydraulic press); it was originally just a cutter and the bending half was added afterwards: the cutter with the HID ran on a 486 board with a dos clone and was connected to the bender’s controller board via an isa card; i checked the bender’s board and it turned out to be a 6502 board… Talk about ol’reliable. I ended up needing to replace the 486 board with a pentium board and running everything trough freedos because someone slammed the steel sheets in the control cabin while feeding them in the machine. I was surpised to find a 6502 based embedded computer running with equipment that came standard with a flat panel monitor for the HID, but i guess when the machine’s minimum lifespan is marked in decades you go for well tested stuff.

I am still resisting the temptation to go back there, dump the roms and reverse engineer the whole thing though
