Thank you :-) I can't quite remember why I started collecting so many
different versions of Star Trek, but if anyone has any other
interesting versons, I'd be happy to put them on the page.

Thank you Gene for coming up with the name of the movie that had the CDC equipment in it. This board can get answers to ANY question I do believe.

OK.

Makes sense.

That makes sense too.
Thanks to everyone who has replied. Now all I need is a machine to run
it on (or an emulator). Any suggestions?

This makes sense.

where my listing came from, I'm pretty certain it was intended to be
run using a Teletype [AK]SR33. On that machine, SO (decimal 14 is
Shift Out) would, as far as I remember, switch to the second colour if
you had a two-colour ribbon. And SI (decimal 15) would shift back.
OK, I can see a use for that, though it's slightly odd in that the
lines where it occurs aren't particularly special, and the text is
bracketed by a pair of '14, not by '14 and '15 as I'd expect. My ASR33
only has a black ribbon, so I can't check if SO is cancelled at the end
of a line (I have a feeling it might be). Oh, well, I better finish
typing and find a way of trying it out...

OK, I guess it's just line noise, and I'll remove them. There's
another place where there's something that doesn't quite make sense to
me (yet) so I'll have a closer look there too (line 740 in TREK1).

I wondered about octal, but decimal 14 is Shift Out which makes more
sense. Sort of. See my reply to John K.

I'm sure that's it. The code has provision for various null inputs
too.

Oh, I have a few of those online, too :-)

Actually, Apple has a testing lab that has a pretty wide range of old
Macs running assorted mac OS versions. Its even free to use if you are an
Apple Developer. The catch is, its in Cupertino, and you have to do the
testing yourself, so unless you are local, or have a good budget, its
tough to use. Poor shareware developers like me have to depend on our own
collection of old macs (of which I just liquidated 95% of my own).

Hi!
I once again tried to get my PDP-8/L to run this weekend. Unfortunately
I am not not yet a PDP professional - I don't have a clue what most of
the modules are doing. I started to read the Maintenance Manuals but I
do not quite know where to start. Maybe you can give me a hint:
I tried the "simpler" instructions like set accumulator, or accumulator
with switch reg. etc.
What I did not yet try are the different jump instructions. I will be
more specific as soon as I tried more instructions.
CLA and STA work, i can set all bits in AC. IAC (increment) and all the
rotate instructions however always set AC to 1 completely ignoring the
previous value.
Where should I start looking for the problem? What information do I have
to gather to narrow down the source of the problem?
Regards,
Sebastian
Does anyone remember the name of the movie that came out in the mid 60s that had a CDC 3600 (I think) as a background in part of it. I had a friend who told me he was the CDC rep during the shooting of the movie, but it's been so long ago I've forgotten the name of it. He said all he had to do was go in each morning and bring the system up and make sure all the lights were flashing, that was the important thing about it. It was definitely a CDC computer, since my friend worked at CDC, but I am not real sure about the model. It was, of course a sci-fi movie....
Thanks for any help and there are movies other than TRON.
Bill Machacek
lo,
are we talking about the Tron movie from 1982?
I just grabbed it in digital format.
