Tashtari's latest activity

Volunteer get! Thanks @David Cook ! Unfortunately the limiting factor here is the ROM rather than the interface - to my knowledge, no...

It's time for another Tashtari shenanigan. (You don't see that word used in the singular very often, do you...) So here's the...

These are things that I'm not going to be able to explain very well (I'm not an electronics engineer either), but I'll try - anyone who...

The 2.8 volts figure is what I measure between ground and Vcc, is that what you're asking? I'm not sure I understand the question.

Success! With a little help (okay, a lot of help) from @zigzagjoe, TashSync is now working on the IIsi without an external power...

Lot of shifting goalposts in this project. Partially the fault of my own particularities, but as usual I'm also learning more minute...

The Toby firmware is working! ...From a simulated signal, at least. Don't have a real Toby card to test with (or a Mac II, for that...

So far so good! I have PIC10F320 firmware now that I've confirmed to work on the IIsi on at least one monitor which I know doesn't...

Yeah, most likely. I was mainly intending to use it over the flat interval in the Toby card's composite signal where the signal has to...

As I continue to chip away at this, I'm getting more into the mindset that a single adapter to do All The Things is not the approach I...

Oh, interesting, the 12F1501 doesn't have OSCTUNE (for that matter, neither does the 10F320/322)... that's strange, I never noticed that...

Ah, interesting. The PIC can take as little as 2.5V, so that has potential... the only worry would be that the logic levels go down...

I took a small break from the main project to make a sync processor for the Apple IIgs (and just the Apple IIgs) and was astonished to...

Rambling ahead, you've been warned. Continuing to chip away at this. Rewrites are always a bit disheartening, but I have to remind...
