    Yeahhhh, I was looking at the eZ80 too, but it just doesn't look like it's compatible enough to be a drop-in super-replacement in these old boxen. All those built-in peripherals get in the way.

    Alright, so. There has been a good bit more interest in people getting these.

    But, given that USPS is all screwed up right now, apparently with 4-5 week delays...

    And given that, while I am...

    I was thinking about that to begin with, but when I started laying it out I got to feeling like it was taking up too much of the prototyping space. My plan was to use a 688 and some jumpers to...

    That sounds like what I was thinking of. IIRC in my case it was something further into the video generation circuit, but whatever it was was pretty much directly tied to the line driven by that soft...

    Yea probably. I want to make sure everything measures just right first though. I used a Model II 64k RAM card as a template and measured very carefully with a digital caliper to make the edge cuts...

    Ahhhhh, I ran into this like 20 years ago but I can't remember what the fix was!!

    There's a line somewhere that switches something on and off that puts the circuitry that produces the composite...

    With just doing HASL, I am fairly sure they will be less than $10, unless they charge extra for all the drilling. I am pretty sure I am still within the size constraints for the budget 2-layer...

    Hmm, I don't have a cell phone (I live in the middle of the NRQZ), and I didn't have any problem registering, and I don't get nagged for more info. But maybe they have changed their stuff since back...

    You could probably post your stuff to github and link to it from here. Or if you don't want to mess with all that, PM me and I'll give you my email address, and then I'll host it somewhere for you.

    Mirrors the trend of the bloat in Linux these days with everyone using appimage packages now, because wahhhh dependencies are so hard. So they include all of the library code, all the way down to...

    I just set up an Odysee account and initiated the transfer of all my YouTube content over there. The site is quite a bit better than the last time I investigated it. I am very impressed.

    Can I preemptively call dibs on a type 4 HDC if you have one? :P

    I think the slowest computer I've used TLS on is a Macintosh IIci. 25MHz 68030.

    I know the 8-bit Arduinos won't do it, so..... I 'spect an 020 or 286 would be iffy. I think Minix 1 would run on...

    This is something that is on my project list, too.

    The timing diagram for the keyboard serial protocol is on page 65 of the Model II technical reference manual, and the scancodes that the various...

    Zoom does some kind of hinky ALC that makes one of my mics hotter than a $2 pistol, too. Which is a shame, because it's a very expensive desktop audioconferencing mic, heh. I tried 4 different mics...

    They are both certainly network cards.

    The top one is extremely likely to be an ethernet card. If that DB-15 connector has a sliding latch on it (unclear in the photo), then it definitely is. ...

    We still have a few around here. Right in the midst of the NRQZ. There are some places where there is basically no cell coverage for miles.

    I think they are all COCOTs, though.

    I liked Eccleston best, despite his short run. He was a darker sort of Doctor. Very intense.

    I quit watching during the Capaldi run. It got way too woke for my taste, sadly. :( Thanks, BBC.

    Yes, at least mine are.

    There are some different case revisions on the HX, though. I think the only change is the volume knob, but there may be others.
