Two existing products are having new spins, one already in-house being tested and another due to arrive in a day or two.  As I’m building boards I always accumulate a list of things that should be changed, so each spin of each board has a few improvements over the previous one.

Right now the SD Shield version 4 is waiting for a hardware test and then software updates.  The new card has a couple new features, some of which can be applied to earlier boards.  Later this week I’ll post a photo and discuss what new can be done with it.

The other change is the good ol’ SS-30 Serial board.  This was the very first SWTPC compatible board we made, and while it was rather simple and did its job well, there were two pins left floating that should have been grounded.  I also switched from a MAX232CPE to a MAX233, so a slightly larger chip but four less capacitors.

In the background I’m continuing efforts to automate more processes and get all the code, CAD files and documentation into a remote source code control system.  This afternoon I’m working on makefiles to create the thumb drive image.

Not Much Going On

Sorry about the lack of posts showing some progress.  The last few weeks have been pretty busy with other projects and not much time was spent at the workbench.  Some new blank PC boards came in, but they’re just revisions of existing projects.  This week looks very busy but maybe next weekend there will be more time to work on products again.

History of Personal Computing Interview


At VCF East, I had the pleasure to meet and talk with David Greelish and Jeff Salzman from the History of Personal Computing podcasts.  We talked about the 6800 and 6809 machines, shows and other vintage computer related topics.  About a week later they asked if I’d be interested in doing an interview for the show… you bet!

On Sunday night we debugged audio problems at my end (rebooting sometimes fixes a lot of problems) and had a nice conversation.

Anyway, here it is!

I started listening to other editions and found it very interesting.  Laid back, no heavy production, just a couple of guys having fun while talking about vintage machines.  Please stop by their website and have a listen.

David and Jeff… thanks!  It was fun!
