EPROMs are Alive and Well … and Living in Redwood City

Well alive yes, but not moving too swiftly. Burning a program into an EPROM, headers needed for auto run, and hardware requirements have all been worked out. Now EPROM applications are needed.

EFROMS can replace the internal ROM(s) to provide bug fixes, customization and expansion of the computer’s operating system. Replacing the internal ROM(s) with EFROMS requires some rewiring but all the internal ROMs are in sockets. Unfortunately, the TS-1500 ROM is in a 24 pin socket which does not lend itself to replacement by EPROM.
