    I guess finding a DEC Rainbow would have been a bit of a stretch for the prop department.

    (Nitpicky observation: in the movie the printer was *next* to the system unit, not on top. Obviously that...

    Perhaps the cache adds a little latency? In any case, unless it's a large difference I can't imagine any improvement in those scores you might get from replacing the original CPU would outweigh the...

    How large is the difference in the benchmarks?

    One thing to remember about the 386sx is if you have most 386 memory managers (emm386 or whatever) enabled it's going to slow memory access down a...

    That benchmarking PDF from Intel specifically mentions interleaved memory and other go-fast bits present on the super-secret lab platform that was used that I am pretty sure weren't in your average...

    Nobody said it was. The 80286 also has the same size queue. The question was how much would the fact that both CPUs have said queue reduce the impact of the longer bus cycles on the 186 relative to...

    It's kind of goofy because the manual for Freestyle Light says that to work right anything that runs underneath it has to be limited to modes 3h, 10h, and 12h, which are standard modes any VGA card...

    Of course, if you were comparing a Tandy 2000 to the *first* rev of the IBM AT that machine ran at 6mhz, only 75% the clock of the 2000, and both it and the later 8Mhz revision had one wait state....

    The reason for the 5v line is it's needed to drive an opto-isolator circuit; the Model I monitor was a *barely* adapted and very cheap "Hot ground" TV chassis. I doubt it draws much power but I can't...

    The counterpoint is that the 80186 does have a small instruction prefetch buffer, so if it’s running an instruction mix that lets it keep that relatively full instead of tearing through memory at...

    Weird.

    Would it be possible to connect the working card to a monitor that has a menu system that will tell you what frequency and refresh the monitor is running at? In principle I'd guess it...

    Certainly understandable; in between temporary drafts when I commandeer extra space the active portion my retro junk hobby is generally confined to about six square feet of permanent real estate.

    A CF should work fine. I'm pretty enamored with a common 44-pin to SD adapter that I've found works more reliably than most CF cards with my 8-bit XT-CF adapter, but you shouldn't have the same sort...

    I would second that it makes more sense to just replace the internal HDD of a 486 laptop with flash storage; you can use a 44-pin PATA to CF adapter (which is essentially a passive wire adapter), or...

    So in the meantime... ;)

    By any chance, assuming you have a working 2K handy, have you ever tried running the Topbench stub on a 2000? Supposedly it uses standard DOS I/O calls to route the core...

    Could you explain how Tandy could have used less external logic? I feel like you're under the impression that the 80186 has more built into it than it actually does. It is *not* a "System on a Chip"...

    From the previous page:



    It seems pretty plain that youíre saying the Tandy 2000 is crippled by not utilizing the capabilities built into the chip (which is not true), with the only evidence...

    I’m not disputing that most 808x machines of roughly the 5150’s vintage shared a lot of the same off the shelf chips. (Being cheap and off the shelf was kind of the unique thing about the 5150 by...

    What onboard peripherals do you think are *not* being used? We can go through these one by one, starting from the back:

    8237: It does *not* have this. It appears nowhere in the parts list in the...

    Uhm, it doesn't utilize the onboard peripherals? I don't have the manual sitting handy, but I don't think that's true. There were some rare pottsylvanian PC clones that used the 186 alongside a...

    My experience with upgrading two Goteks to FlashFloppy was completely painless. (I used the USB method.) The only thing I would recommend as an add-on is swapping out the stock numeric 7-segment...

    Again, the model number you quoted was for a 1.44mb Gotek. *Unless they improved the firmware and didnít tell anyone* that Gotek isnít going to care if you format your USB stick for 720k, itís still...

    The 9 sectors per track formats should run at the 250Kbs datarate. Which I'm pretty sure a 1.44MB Gotek won't do with the stock firmware.

    For probably irrelevant comparison the generic ISA RTL8019A I have dangling precariously inside my 1000 HX-based mutant spdtests at about 73KB/s transmit, 87KB/s receive. Machine has a V20 if that...

    Hey, that's cool!

    I was vaguely thinking about trying to lay out a Plus card with the full RTL8019AS because it seems to be semi-readily available for only around $4 a pop. It has decode circuitry...

    The way the default Gotek firmware works is it relies on having the USB stick "partitioned" into a bunch of RAW floppy-sized slots. The ICAS software lets you select the different sizes so you can...
