========================================================================
1. After installing SIMH HP2100, you may test it using the included
basic1.abs as indicated in the simulator documentation.
2. From http://oscar.taurus.com/~jeff/2100/index.html, get the following files:
algol.abs
bcsioc.rel
bcslib.rel
bcsloadr.rel
bcsprep.abs
bcsptp.rel
bcsptr.rel
bcstty.rel
sio16k11.abs
BE SURE YOU HAVE PERMISSION TO USE THESE FILES.
3. Prepare a bcs16k.abs tape (linker) using bcsprep.abs and the .rel
files you got. (See below on how to do this).
4. The downloaded file include a configured sio tape. It is configured
for 16k words using the following units:
tty 11
ptr 13
ptp 20
5. change the default device numbers and load the sio tape, as follows:
set clk dev=12
set ptr dev=13
set ptp dev=20
load sio16k11.abs
6. Load the Algol compiler:
load algol.abs
7. Compile your HP Algol program from an ASCII file helloworld.alg:
-----------------------------
HPAL,B,"PROG"
BEGIN
WRITE(2,#("Hello world"));
END$
-----------------------------
att ptp helloworld.rel
att ptr helloworld.alg
run 100
8. Link your .rel file(s) with the bcslib.rel. You need to reaassign
the device numbers to the default values:
set clk dev=13
set ptr dev=10
set ptp dev=12
load bcs16k.abs
att ptp helloworld.abs
att ptr helloworld.rel
Set bits 15 and 14 of the switch register to 1:
de s 140000
run 2
Repeat the following steps for any other tape you may
have (other procedures for example):
de s 140000
att ptr OTHER_FILE.rel
run
Finally, link the library, also setting bit 2 of the
switch register:
de s 140004
att ptr bcslib.rel
run
de s 140004
run
det ptr
det ptp
9. You may now run your standalone program.
load helloworld.abs
de s 000000
run 2
------------------------------------------------------------------------
10. To prepare a BCS tape, duplicate the commands shown in this log:
