I have Lunar Lander (in Focal) working again on my PDP-8/A with two RL02
drives (about which you have been reading a lot lately). It's been so long I
don't remember where I got the text file (LUNAR.TX) from, but it's on both
my RL02 OS/8 image and the physical pack...
The rather unusual way I got the Focal program saved onto the RL02 was to
punch the text file to paper tape on the Teletype, start Focal, read the
paper tape from the Teletype, then save the "typed"-in program to disk.
Think that's how I did it quite a few years ago when I got the system, too.
So far my best game is 0.20 mph "perfect landing - lucky!" :) Takes me back
to junior high in the 70's...
Anyway, I'd like to do the same thing in SIMH (get the text file into Focal
and then save it as a Focal program). Is there any way to do this with SIMH?
Can I assign the text file to a paper tape reader, for example?
thanks

I have connected my Teletype Model 33 to the SIMH console via a DECserver 90M using
reverse telnet. I *think* you can connect SIMH directly to a serial port now, if so that
might be a simpler way.

Rob

This should work fairly easily using the high speed paper
tape peripherals of SIMH. You can equip an output file
for the punch, punch the "tape", then equip that file for
the reader, and I believe the asterisk command or some
such Focal feature will read it in. Save to disk, and you'll
have your text file converted.
Low speed paper tape on SIMH is more problematic, as
you don't really have an 8 bit channel, flow control isn't
implemented, etc. (At least on the console that is shared
with the SIMH command prompt.)

I have also used 'expect' to drive SIMH to have my 'expect' robot play
tic-tac-toe vs the PDP-8 (endlessly ...) and to drive files into FOCAL and BASIC

Vince from the command line as typed text.
