    I vaguely remember you recently got a Tandy 1000 working, I think it’d be worth it, just for the heck of it, to install the Tandy 2000’s drive as drive “b” and see if you can run it through its...

    We ignored the whole Black Friday thing at my house; personally spent the non-chore/non-completely-vegetating portions of the day working out the kinks in integrating a new clock divider circuit into...

    I second either using Xlib or using some kind of “display proxy” layer in between your home brew code and the display. Likewise it’s been a long time since I even thought about it, but my...

    The 2000's drives are double-density 80-track, same as a 720k 3.5" drive, so they at least theoretically could work in a PC if properly configured. When your friend tried this in 1987 did you first...

    Do the "TED" Commodores (C16 and Plus/4) have the same serial timing issue as the C64? If they don't then I'd think a 1540 would work with a C16, but I honestly have no idea.

    So... starting from the divide by three I came up with above I hacked together a switchable divide by three/six circuit. Normally I'd think it'd make the most sense to either divide by two and use...

    That magnetic record bears an eerie resemblance to "3M Sound Page" system from the 1970's. (The latter is just "flipped"; the recording medium stays in one place while the recording head both moves...

    You *can* have a computer that behaves essentially identically to one, since the contents of that software is well documented (MOS even published the assembly source), so I wouldn't come down too...

    I don't know myself how *common* it really is for the RRIOTs specifically to fail, but they seem to have a reputation. (The older Commodore disk drives for the PET used them and they're listed as a...

    Maybe a little off-topic, but sometimes I use a really trash method to allow my Tandy 1000 to telnet into my Apple Macbook: I installed "socat" with Homebrew and when I want to telnet in I run this...

    People should start including sockets for these on XTIDE cards. They're easy-peasy to tack onto things like that.

    It's been a long time since Windows Server was even remotely my bag, but if I had to hazard a guess the Windows 2000 telnet server is probably trying to use kerberos or NTLM instead of password...

  15. Question for the GAL Gurus: Most efficient Divide by three?

    I'm still sort of a newb at this whole "programmable logic" thing, so I have this strong feeling I'm probably missing a really obvious and cool way to accomplish a thing. So here's a question for the...

    No comment on what a KIM-1 is actually “worth” as a collector’s item, but offhandedly I will observe that it might not be the best ancient computer to actually try to use recreationally today. My...

    I was going to suggest Eadweard Muybridge’s work as a possible candidate, but his rigs used the Collodion process.

    Also, I suspect that dedicating a whole camera for each burst frame is stretching...

    I think the reason that's there is to ensure signal integrity of those signals across a cable. I don't bother buffering those on my homebrew cards, but the assumption with those has always been that...

    I'd definitely agree with not worrying about the drives yet and concentrate on getting the computer itself breathing; you're not going to be able to meaningfully do anything else without video output.

    The PCjr's tech manual says it's compatible with 2716 or 2732 EPROMs. I'm sure the PCjr folk probably know where the BIN for it is, although I imagine you might be able to find it in a MAME ROM...
