Special Interest Points
There are a few other things about the Diab lo printer that
should be mentioned. If you want to use it with another
computer, as for example an Apple / / / or a Commodore
8032, you must first correct one of the wires on the HPR04
board inside the unit to insure proper handshaking. The
Apple II will work properly with or without this modification,
but those of you with two computers may want to make this
change.

IAC, and is the present Software Chairman. He started

Biii Budge, creator of
"Rosier Blaster," needs It:
Follow the maintenance schedule closely according to
the manual to insure long term operation. The printer is
known for long term operation with a minimum of breakdowns,
and most of the people 1 know (including myself)
have never had a repair, unless they spilled a milkshake
down inside the machine. Lightly oil the "rail" periodically
for smooth print operation, as the manual recommends.
Always keep the unit covered when not in use, and provide
good air circulation for cooling when it is in use. If you plan
to buy a tractor feed, as 95% of us do, pay a little extra and
get the bi-directional unit. It makes life a .lot easier both for
normal use, and if you want to do something fancy like
reverse printing.
You could operate the unit with the cover off if you pull up
the cover switch, but watch out for fingers, or hair getting in
the works. Never touch the print wheel while the unit is on. It
tries to put it in the proper sequence, and the slightest touch
will cause it to jump. This includes the wheel-ribbon assembly.
By the way, the entire wheel-ribbon assembly moves
easily right or left only when the power is off, to change
ribbons, wheels, etc.
And last but not least, I have included two HI-RES dumps
using the Graphics Printing System by Paul Mosher M. D., of
myself and Donald Duck (I'll let you guess which one is me).
As we have .seen, this printer can do just about anything, and
the applications are limited only by your imagination.
