    For what it's worth, I've had success imaging the 2gb CF card from my 5160 under Windows, and getting PCem to boot from the image.
    May not be relevant to your case, but others might find this...

    Looks like one of those CGA clones that can be jumpered for monochrome output (http://www.uncreativelabs.de/th99/v/C-D/52640.htm), but only with a single level/intensity of green, so the result...

    Well... what video card are you driving that monitor with?

    The 5151 was intended for MDA/Hercules resolutions (720x350), but the screens in your photos look like something out of a CGA or similar...

    Ah yes, the BASIC manual also makes it clear that "medium resolution" refers to the TV/Joystick option. More than 40 columns/320 pixels wouldn't have been very useful on a TV... 4 colors still ain't...

    Nice!

    I was considering Pillow for something very similar (generating the bitmap font previews found here), but I ended up being even lazier, and wrote my script using ImageMagick (and ffmpeg,...

    Tandy 2000 text display

    A couple of questions I have about how text output works on the Model 2000. I don't own one so I can't answer them myself, but call it historical research.


    In text mode, is 10x16-pixel...

    Turns out that PCE is no slouch even with Teledisk images. I tried those HP-150 disk dumps as they were - wasn't expecting much, but MS-DOS with HP150.SYS loaded read the files just fine. :)

    Some very early Model Ms support the XT protocol, and maybe some were even XT/AT-switchable.

    However I think the BIOS *also* needs to have Extended Keyboard support to handle them. The Rev. 3 XT...

    Ha, the 8x8 charset in this one is the Hebrew code page (862). Nice find.

    Was this sourced here in Israel? I don't think I've *ever* seen a PC-1 around here. :)

    86box uses a more accurate 808x CPU core (reenigne's XTCE) than PCem. It also does a surprisingly good job of running almost the entire 8088 MPH demo, so the proof is in the pudding.

    For most...

    I'd be surprised if this isn't somewhere in one of the big shareware collections like PC-SIG's, PC-Blue(/Green/Red), RBBS-in-a-Box etc.

    Those are huge piles of disks to wade through, but they're...

    Gotta say, even the no-buffer version with bit-0 polling looks good! True, it's visibly slower but that's really not a big deal with a game of this type. You could say it's faithful to the...

    Thanks. Those are HP 150 disks; code extracted from those may be useless, but data not necessarily so. ;)

    Do you guys happen to know how data can be extracted from such images? They're seem to be out there in Teledisk format, but attempts to convert them to IMD or raw formats for extraction (e.g. using...

    That's correct... you can use either one of those bits, but the behavior is different:

    Bit 0 is the real indicator for when it's "safe" to write to CGA RAM. It signifies "blanking", which is...

    Hm, yes, this is a different problem. But that might depend on more than 512 KB being *available*... I do recall something about a bug where a signed comparison is done on the amount of free memory...

    Having less free memory might actually help. Some old compilers, packers, etc. produced buggy code, which fails to allocate memory if DOS finds enough space for the program in the first 64K of RAM....

    Hm, I assume it doesn't do anything funny to INT 16 (hooking/revectoring) before it makes those calls?

    IIRC there was nothing to suggest that it can do any switching at all under software control - only manually. But then, that thing came in a used 5155 with no documentation whatsoever. The actual...

    Might the freeze be related to the keyboard (unhandled keystrokes filling up the buffer so the 5155 ends up beeping at you)?

    See, I just remembered this age-old question:...

    Okay, that looks like a consequence of the MBC-775's text mode font being a bit different from that of the IBM CGA. Which is something I already mentioned, so I should've connected the dots there....

    Possible clock discrepancies aside: did you try playing with the settings on the initial calibration screen some more? in particular changing "CGA model" to "new"?

    Since you were going to run 8088 MPH: I don't know much about the MBC-775, but it looks like the internal CRT shows RGB video - does this thing have composite video out?

    If so, it'd be nice to...
