If you still want to read that ROM instead of capturing the patterns
Anyone out there have a dump of the VT100
character ROM? (This is the
ROM located at E4 on the VT100 PCB, labeled as 23-018E2-00)
The patterns are shown on pages 4-78 and 4-79 of EK-VT100-TM-003, "VT100
Series Video Terminal Technical Manual". It also explains why the
characters you see on screen don't look exactly like the ROM pattern,
due to dot stretching.
from pictures in a doc, it appears that ROM has the
same pinout as a
2716. If that ROM was in a socket instead of being soldered in
place
I would pull it out of my VT100 and try reading it as a 2716 myself.
What sort of hardware are you planning on building for an emulator?
