- The following is the original 'announcement' of the availablility of the
- pdp8 and pdp11 simulators to a private list. It has been edited to
- remove certain sensitive pieces of information:

-
- I am pleased to announce the (internal field test) for the PDP-8 and
- PDP-11 simulators. To get the sources and the simulated OS8 and RT11
- disks, copy xxxxxx to your system and proceed as outlined in these notes.
- Sketchy documentation on the simulators is in file 0simdoc.txt
- [ed. - the OS8 and RT11 disks are not available due to
- licensing issues ... if you have a disk, simply copy
- the disk to an image file and use that.]
-
- 1. The simulators work on both VAX/VMS and on Alpha/OSF1.
- [ed. - and on mips/ultrix]
-
- 2. Each simulator includes a CPU, memory, reader, punch, terminal, line
- clock, RK05 disk, and RX01 disk. (The PDP-8 has an RF08, and the
- PDP-11 has an RL11.)
-
- 3. There's a VMS build file for each simulator:
-
- pdp8_build builds PDP8.EXE
- pdp11_build builds PDP11.EXE
-
- [ed. - A preliminary Makefile is provided which will build
- the simulators, but may not be as concise or as full-purpose
- as it could be]
-
- The build files include the debugger, remove that if you want.
-
- For OSF/1, the build command lines are:
-
- cc pdp8*.c scp*.c -lm -o pdp8
- cc pdp11*.c scp*.c -o pdp11
-
- 4. The simulators are only partially tested.
-
- I would APPRECIATE YOUR FEEDBACK. Feel free to try small programs
- to test the EAE, FP11, and devices. If you find bugs, feel free to
- look through the sources and send me the fixes...:-)
-
- [ed. - The author has set up a mail alias to receive such
- mail. You can send mail to him at dsmaint@pa.dec.com]
-
- 5. To get the simulated operating systems up and running (OSF/1 shown):
-
- % pdp8
-
- PDP-8 simulator V1.0
- sim> att rk0 os8.dsk
- sim> boot rk0
-
- . <-- OS/8 prompt
-
- This is pretty much instantaneous on either VAX or Alpha. You
- must first set the date (note that OS/8 REQUIRES CAPITAL LETTERS
- FOR INPUT) and then you can type HELP or DIR to explore further:
-
- .DA 14-MAR-94
-
- .DIR
-
- For the PDP-11 and RT11:
-
- % pdp11
-
- PDP-11 simulator V1.0
-
- sim> att rk0 rt11.dsk
- sim> boot rk0
-
- RT11SJ (S) V5.04
-
- .
- . <-- RT11 prompt
-
- Note that on a slow VAX (eg, a 3100) it takes 45 seconds to get to
- the banner, and another 15-20 seconds to get to the prompts. On
- Alpha/OSF1, it takes a few seconds to reach the prompt. You can
- then set the date, type HELP or DIR, and so on. RT11 accepts lower
- case input.
-
- The simulator is stopped by typing ^E (control-E). This can be
- changed through the WRU register.
