Yes, the so called basic software is executed always from EPROM. The ROM
board, ...-450 or 0150 holds basic software on 2764, and if "PC-Model
B" board is not present, there are also 6-8 sockets for PLC program. No.
1 & 2 are Fanuc programs, No. 3..6 is the PLc program itself. If a.m.
board is present, than PLC software is there, and again No.1 & 2 (G241,
G242 mark) is basic Fanuc software, 3 .. 8 is PLC program.
NC and PLC parameters could be entered of course by hand, if a listing
is present.
