I've only been dipping in and out of StarDot recently, because I've been squirreling away writing a RT11 Host interface for PDP11 BBC BASIC. It's been a lot fiddlier that I expected, coding for RT11 is like CP/M but without the friendliness. Yesterday, I achieved a major milestone, got LOAD and SAVE working (via OPEN, READ/WRITE, CLOSE).

For extra excitement, I've been testing on an emulator for a Soviet PDP-11 clone, the UKNC:

The next step is to work out how to do system() so OSCLI can call RT11 commands and I can *DIR the disk.

Code: Select all

First looks at Vectrex Elite, author has a good predigree (although don't know him on Vectrex).

Maths precision seems a little too low, but 6809 should easily be able to do a good job of this game as long as text is kept to a minimum.

There's a great demo I once saw showing how return currents in a ground plane follow - or try to follow - the forward path in the signal layer. I've tried and failed to find it. But I did find this demonstration, probing a deliberately defective ground plane with an inductive probe:

That's good, but not it! It was short, it involved some sort of transparent acrylic sandwich, and it lit up according the return current path, either because of tremendous voltage or because of embedded LEDs. I might be confusing two demos...
