The Programmer's manual for the vt102, vt131 speaks of something
called "an alternate ROM character set". Apparently there's the
ability to define a character set on an eprom, place it in some
reserved slot on the terminals motherboard (I've seen the slot, it
exists), key in an escape sequence and set the vt102, vt131 to use a
different character set. I heard the vt220's and vt240's have a
similar option. 

In foreign countries this was a standard "add on", and I suspect they
may have an APL chip too ... but the vt102, vt131 are pretty old, and
I wasn't able to find specs for the eprom, the format they use for
coding the character set, etc., etc.

So ... If anyone has any information about the alternate ROM character
set, I would be most interested; especially for the vt102, vt131 which
do not take downloadable char sets. By "information" I mean docs on
the coding scheme and the eprom, a sample of a chip for some character
set (I could figure out the coding myself), a printout of the contents
of such an eprom, etc., etc.
