Re: System 34

All we had was Autocoder, and of course machine language. I still have a
couple of 1-card (80-col) programs sitting around.

For those interested, here's a note from the Systems Unlimited Online
Software Museum (http://www.sysun.com/):

"Bob Supnik of Digital Equipment Corporation has written, over the last few
years, a series of wonderful "computer history simulators", which are very
accurate simulations of real computer systems of the past. Included in his
package (available free on the net at Digital Equipment Corporation's FTP
site (ftp://ftp.digital.com/pub/digital/sim/) are Digital PDP-1, PDP-6,
PDP-8, PDP-11 simulators plus a DG Nova simulator and one for the IBM 1401.
We use a slightly modified set of these simlators for OS/8 (on the PDP-8),
RT-11 and UNIX 7th Edition (on the PDP-11), and RDOS (on the Nova). In
addition, we've written an Altair simulator and a Z80 simlator using the
standard design criteria and run Altair Basic and CP/M on those."

As I recall there are actually two different simulators for the 1401. Plus
the original Autocoder compiler source code.
