Actually, yes, I was thinking along the lines of
something which
actually made use of the original firmware. That quite possible isn't
practical though as presumably at least some vendors did something
really oddball rather than using an off the shelf CPU :)
But yes, "warts and all" through use of the original ROMs would seem
ideal to me (from an accurate as possible emulation point of view).
There's almost certainly far less of an issue with publishing these
ROMs for terminals I would have thought - lots of the companies in
question have either gone under or are hardly likely to care (unlike
the situation with MAME and games manufacturers)
Along these lines -- does anyone have ROM images (preferably program &
character roms) for the firmware in, say, a VT100? This discussion has
piqued my interest in writing a hardware-level VT100 emulator (just what
I need, another software project to distract me from the dozen or so I
haven't yet finished...). I own a VT100 but I have no means to read the
firmware off of it -- if anyone out there has an image I'd love to play
around with it. Any good sources for hardware info on the VT100?
Thanks,
Josh
