448455/* VT1xx models:
449456 * VT100 - 1978 base model. the 'later' rom is from 1979 or 1980.
450457 *    The vt100 had a whole series of -XX models branching off of it; the
r19454r19455
499506    The DPM01 supposedly has its own processor and roms.
500507 * vt125 - 1982? base model (stock vt100 firmware plus extra gfx board
501508   firmware and processor) vt100 with the ReGIS graphical language board
502   (aka GPO) installed (very advanced full framebuffer raster graphics, with
503   color, text rotation and scaling, etc. , has backwards compatibility mode
504   for vt105), AVO optional; Includes a custom STP board.
509   (aka GPO) installed (almost literally a vk100-on-a-board, but with added
510   backwards compatibility mode for vt105/WG, and 2 bits per pixel color),
511   AVO optional; Includes a custom 'dumb' STP board.
505512 * vt131 - 1982 cost reduced version of vt132, no longer has the vt100
506513   expansion backplane; has the AVO advanced video board built in, as well
507514   as the parallel port interface board, and supports serial block mode.
r19454r19455
513520   installed;
514521   The daughterboard has two roms on it: 23-017e3-00 and 23-021e3-00
515522   (both are 0x1000 long, 2332 mask roms)
516 * vk100 'gigi'- graphical terminal similar to the vt125, but somewhat more
517   primitive; more or less a vt125 without the screen;
518   very little info so far, more research needed
523 * vk100 'gigi'- graphical terminal; the vt125 GPO board is a very close derivative;
524   relatively little info so far but progress has been made.
519525   see vk100.c for current driver for this
