UNDOCUMENTED VIDEO FEATURES
FOR THE KAYPRO 10
By Ron Mozer
The KAYPRO 10 has several undocumented features available to the
user which are undocumented in any of the Kaypro manuals. These
features include a 25'th line and the ability to save and recall
the cursor possition. If you look at the owners manual for the
computer you will find a section which describes character attri-
butes commands. These commands allow inverse video, blinking,
reduced intensity, etc. This is documentation on two more of the
commands.
The table of commands can be updated to the following:
To Turn ON: To Turn OFF:
Inverse Video ESC,"B0" ESC,"C0"
Reduced Intensity ESC,"B1" ESC,"C1"
Blinking ESC,"B2" ESC,"C2"
Underlining ESC,"B3" ESC,"C3"
Cursor ESC,"B4" ESC,"C4"
Save Cursor Pos. ESC,"B6" To Recall ESC,"C6" <--- New
25'th line ESC,"B7" ESC,"C7" <--- New
As you can see there is an obvious gap for the "B5" - "C5" attri-
butes. I have not found out what these do and would be interested
in hearing from anybody that does via the Mesilla Valley RCP/M
(505)522-8856.
What follows is a sample MBASIC program which demostrates these
features:
