The Kaypro 4-84 boards (new kaypro 2's, kaypro 4's and kaypro 10's) --those
with reverse video, etc. -- use screen memory that is accessible only
through the video controller.  The Kaypro factory roms are rather slow and
fall behind when scrolling (e.g. when the cursor gets to the bottom of the
screen and a linefeed is sent). 1200 baud is about the limit for
continuous-stream text.

Plu*Perfect Systems is writing a new rom for Kaypros that includes a
snappier video driver.  I've  used a test version effectively at 4800 baud,
and with almost no glitches at 9600. That seems to be the limit of what can
be done in firmware, given the hardware memory interfacing.

When ready, it will be available from them and Advent Products.
