FOUR FREE PROGRAMS!
As a special bonus, here are four programs which are fun to have.
We hope to include proper assembler listings of these programs in
the software library soon, so that you will be able to see how they
work. Some of you who have bought games tapes from Henry’s Radio
will have seen some of them before, but there should be some which
you haven’t yet seen.
You should find all the programs self explanatory, given the notes
printed with them. The last column of numbers on the listings is
a checksum, so don’t type it in!
The programs will run under NASBUG T2, B-BUG or NASBUG T4. We hope
to reassemble them for NAS-SYS one day.
One point about REACT. It uses its own special keyboard scan
routine, and it is essential that the spare keyboard input pin be
tied to +5V, not to earth. (This is the same modification required
for the Tiny Basic.) Connect pins 7 and 8 to pin 16 of the keyboard
socket to solve the problem. This prevents the spare input lines
To play OTHELLO you need to know the rules, but you may be able to
deduce them since the program doesn’t let you cheat and shows you
where you can move. It scores the game and provides quite good
opposition. Remember to press the space bar to let it move. It can
also simply supervise a two human player game.
STOP PRESS: This preliminary board layout was found by our own Investigative Journalist
on the desk of NM’s ace designer Heath Robinson-Crusoe. Concealed beneath a copy of
International Times was also a breadboard prototype, but this disintegrated before it
could be photographed. Robinson-Crusoe was unavailable for comment, but sources close to
the Industry suggested that the device was actually available some time last year.
