some history

20240819 had an awesome chat with merlyn yesterday and have many things to begin remembering. will just focus on decwar here. my starting point - ‘new’ raspi5 prepped and ready to integrate into pidp-10 front panel. pidp-10 software is installed and running great for months now. first played with its - emacs, lisp, spacewar, adventure, etc. then switched to tops-10 - sos, macro, fortran.

yesterday merlyn shared the disk image he’s built up. it has a working decwar, old fortran iv needed for that, tops-10 7.03 monitor, etc. here’s a minimal simh script which roughly speaking could boot it

set cons telnet=1025
at rpa0 dskb.dsk
at rpa1 dskc.dsk
at rpa2 dskd.dsk
boot rpa

was curious how the pdp10-kl binary in pidp-10 package would react - the package binaries were built by richard cornwell? here’s what that looked like

noah@raspberrypi:/opt/pidp10/bin $ ./pdp10-kl dsk.txt %SIM-INFO: Created blink_thread warning: failed to set RT priority %SIM-INFO: PiDP-10 FP on

KL-10 simulator Open SIMH V4.1-0 Current /opt/pidp10/bin/dsk.txt-1> set cons telnet=1025 %SIM-INFO: Listening on port 1025 /opt/pidp10/bin/dsk.txt-5> boot rpa %SIM-INFO: Waiting for console Telnet connection %SIM-INFO: Running Killed

it didn’t crash and burn immediately - but didn’t really boot either.

next step seems to be to build a simh pdp10 binary matching what merlyn uses!:)

wootwoot! quick update - plain vanilla simh pdp10 binary built and booting from merlyn’s disk image first try:)

set cons telnet=1025
at rp0 dskb.dsk
at rp1 dskc.dsk
at rp2 dskd.dsk
boot rp
