…and other stuff.
I’ve got Michael Evenson’s SWTPC emulator up and running, so now I’m slowly working from the top down (writing FLEX drivers) and the bottom up (drivers in EPROM to do SD disk reads/writes). More and more of the disk logic is going into EPROM as it’s being properly tested and debugged. Maybe by next weekend I’ll have something running. The actual board hasn’t been designed yet but it’ll be easy to lay it out once the software is working.
The other big project is my son’s Eagle Scout project in a couple weeks, so that is high priority for now and consumes a fair amount of time.
I’ve also been using the 3D printer a lot more recently. There are some vintage computer pieces that just aren’t made anymore and hopefully I can fabricate them myself.
