The Dots Program
- I've posted a zip file (dots.zip) in the files section with an
assembled version of the Tom Pittman DOTS program (source code
provided by Lee Hart and converted to PSUDASM format).
The program accepts keyboard input and displays it as proportionally
spaced dot matrix characters via the 1861. It is a version of the
output side of the i/o drivers for the Pittman tiny basic.
Besides being a neat hack it's an excellent example of the kind of
programming Pittman could do. It's full of all kinds of things we
would never dream of doing today but just had to have in memory-
This code was the subject of two long articles in Kilobaud in early
1979 which are also a great example of Pittman's style and obsessions.
Thanks for the source Lee, this was fun. I had to make a couple of
small changes by the way to get low memory initialized properly.
