I no longer have my Percom Electric Crayon, but have some software I wrote in the early 1980s that made us of it. (The Electric Crayon attached to the printer port of the TRS-80 Model I, and generated composite color graphics on a separate monitor via EGOS commands.) The manual, as I recall, included programming instructions and an assembly listing of the EGOS firmware embedded in the unit.
I was thinking about building one using modern parts, but would like to look at the EGOS manual and/or EGOS assembly listing (preferably both), to make sure what I put build is 100% compatible with the original.
If you have readable a scan of this material, I'd be very interested. I would even pay for it.
