    That thing has a completely different motherboard compared to a standard Model I; it looks like it has a printer port built in, an onboard power supply, etc. And what’s with the sidecar disk...

    Errors would be expected behavior if you pulled the DMA controller off an original memory card; no DMA chip means no RAM refresh. (Modern cards that use SRAM are fine without it.)

    So, yeah, that’s...

    On a 1000/1000a with a period-correct memory card removing the memory card will do it. Of course then you only have 128k to work with but it should be enough for formatting a disk.

    As I said, my...

    While it still boggles my mind that a dirty 286 selling for over $300 isn't particularly noteworthy these days (dang, do I wish I had the contents of my garage circa 1998-ish to sell right now...) I...

    I tried setting a disk image on my USB stick read-only with ATTRIB +R and this is what I get on that image with flashfloppy. (Which according to the docs honors this attribute as a write-protect...

    The character ROM is "hardwired" to the pixel output chain in all PETs, the CPU physically cannot read it. But it doesn't really matter because all PETs have both the "business" and "graphics"...

    For whatever it's worth I don't think I've had any issues with any version of DOS formatting disks on my DMA-less 1000 EX and HX, so I'm kind of skeptical of this being a BIOS issue. For sanity's...

    The CT1336A chip on it is a Soundblaster 2.0 part, so it is almost certainly a "genuine" OEM product. There's no silk-screening on the board anywhere with a "CT-xxxx" model number? (Or an FCC ID, or...

    There are some disassemblies of several Tandy 1000 BIOSes here:

    https://github.com/ricardoquesada/bios-8088

    But there's not a lot of work done yet on actually commenting them.

    Pretty sure I tried it on my DMA-less 1000hx and, yeah, no dice. One of the few programs that cares about that.

    The Kmart website's store locator doesn't own up to any locations still being open in Connecticut, but apparently figuring out how many locations there are still operating in some capacity is an...

    If it didn't work in any computer I'd suggest trying to reseat the DAC and BIOS chips, I resurrected all of a batch of "dead" OAK VGA cards by doing that, but since it works in the AT bus machine I'm...

    I actually sort of like the tick noise. It's audible proof my amazing wooden heap of a computer actually got past POST. ;)

    I dunno, you'd be surprised/saddened how many people think they're "buying American" when they purchase these zombie brands.

    The one that really made me laugh was when the Curtis Mathes name...

    Some of the pinout differences are positively weird, like single address lines shuffled out of order in a block that mostly match up. They apparently wanted to make *sure* nobody accidentally dropped...

    I kind of doubt a disk cache will add much speed to an XTIDE that's configured with a flash drive, honestly. For laughs I once tried setting up an EMS RAM disk on my Tandy 1000 HX (yes, I have 1MB of...

    It works on the PC-DOS 2000 install on my HX, but I guess that isn't the same thing.

    You could always resort to "mem /c | more", I guess.

    Are you sure that your "RCA" TV wasn't made in Korea? In the consumer electronics space RCA hasn't been any more than a label since, man, like 1988. Any television with an RCA label made in the last...

    But they're not identical, at least if a Google Image Search is a reasonable guide. Only the LC II motherboard has that unpopulated footprint for (presumably) a 68881/2, and the big fat ASIC that has...

    Basically the same one-and-only advantage that you get with any gaming console, IE, the game designers get to optimize for one known universal hardware configuration so you can be *reasonably* sure...

    My 2013 "Smart TV" stopped being "smart" sometime around 2017 or so after it stopped receiving software updates, causing it and YouTube/Netflix/et al to start growing apart. Considering how much an...

    4K TVs look amazing when you're in the showroom right up next to the screen and it's playing a high-bit-rate demo, but I know I'm personally far too blind to tell the difference from the ten feet-ish...

    The Phoenix BIOS copyright date is 1988, which post-dates that revision of the Tandy 3000. (The original "3000 HD" with the 8mhz/512k motherboard as pictured was replaced in the 1988 Tandy catalog...

    The picture's a bit blurry but it looks to me like the motherboard only has 512k of socketed 41256s on it. Error is probably from the SIMM expansion card, unless the machine has a separate 128k...
