The answer is true. the difference in the charsets is what the non-ascii
mapped chars look like. (symboles and arrows and other neat glyphs.).

The ROM images are available as C character stucts in my Solace

characters sets (I don't know if that is true or not). Both are
available at:

Download the source. Look in charset_6574.c and charset_6575.c You have to be kidding me. All you need is a
2764 and a programmer.
It's a ROM and the pattern is in the manual, what could be easier?
Actually if someone were building I'd suggest using a 2764 over the
part used on the VDM1 as that was a two or three voltage part and
27C64(or even a 27C256) is common as flies plus lower power.
Well if I still had the manual let alone the the VDM ... :(
