@j4james asked about the nuances of mouse input from archaic terminal emulators and included a Python test script.
I got results from VWS VT200/ReGIS terminal emulator via [simh][] VAX emulation. I don't expect Python runs under VMS 4.7, so I pulled some shenanigans. In brief: I ran the test script on the host computer,
| This presumes you are using the disk image from bit.ly/smalltalk-80-vax | |
| and the 2019 version of SIMH from https://www.9track.net/simh/vax4xx . | |
| To run simh: | |
| $ bin/vax42b | |
| If you have simh's autoboot turned off, you'll need to do: | |
| sim> boot |
This is a work-in-progress collection of notes I've been making as I'm exploring the Heathkit H89.
When you turn on your machine it will beep twice: Once for the main motherboard and once for the terminal board.
Before you boot a disk, you'll see the H: "monitor" prompt. To run a memory test from the monitor, use G 7375. To boot a disk, type B and hit RETURN.
If a program hangs and ^C (Ctrl plus C) doesn't help, try pressing right Shift plus Reset.
