What cards exist that you can plug into the VT-100 backplane?
Has anyone any experience with making your own card to plug into it
for a graphcis overlay feature?

What immediately comes to mind was thet DEC RgGIS graphics
was available as an upgrade (and also bundled as the VT-125),
and a Digital Engineering (3rd party) graphics board called
"Retrographics" VT640 that did Tektronix codes.

they called it Retrographics back then. How ironic.

You could purchase an upgrade kit which includes the CP/M boards and a new
backplate for the unit to accomodate the additional I/O connectors. From what I've
read, the kit also included a replacement "VT-180" badge, although my 180 still
has the VT-100 badge and a little red sticker that says "special option
installed".
I have photos of the individual boards on my site.

Wasn't the VT-180 basically a VT-100 with an added Z80 board and external
floppy? Was there a VT-100-to-VT-180 upgrade path?
