The 6500/1 should be some sort of a microcontroller, not a simple CPU. This makes sense, since the 1520 has virtually no other components except that MPU. A datasheet of the 6500/1 should be on funet, I think I saw it there. Now I wonder if it is possible to read the internal ROM of that chip? For this purpose one of Ruud's loose chips would be nice, so I don't have to desolder the one from my plotter. I think I'll have a look at the datasheet to see if the ROM is readable from outside.
