    You could always print one for now, then later replace it if/when you find an acceptable replacement.

    I got a good look in there, and the chip is an NEC UPC1031H (datasheet HERE, I think).

    Unfortunately, I'm away from home at university right now, and don't have access to my scope.

    Do you have the schematics? I haven't been able to find any for my version -- a BM-12au.
    Interestingly enough, LGR actually found and restored one of these.

    As I said, it's the entire raster. A second video showing this is

    I've tried fiddling with the vertical hold, vertical size, and another control that...
  5. Monochrome monitor picture "bounces" intermittently

    So I recently purchased a monochrome green monitor at VCFMW, to go along with another purchase, an Apple ][. It seems to work well enough, but the picture seems to, every once in a while, bob up and...

    Man, what roads are you driving on? I'd love to start finding IBMs on the side of the road.

    The Tandy Model 100. 'twas the most portable computer of the early '80s.
    Still more convenient than many laptops today -- what modern laptop can you run for a month on a single charge, boot in...

    Hugo is correct, the SCREEN pot is on the back of the CRT tube.
    However, once you do that, the picture is likely to be out of focus, and you'll have to adjust the focus knob (on a plastic thing...

    I'm not Chuck, but I'd recommend posting a thing in the "selling" section of the market-place forum.

    Nice! Was this from that typesetting business? I got a Nova clone and a TTY from that guy. Unfortunately, mine didn't come with the IO board, so I'll have to find one... somewhere.

    Toshiba Libretto floppy compatibility

    Will a Toshiba Libretto accept (i.e. boot off of) non-Toshiba PCMCIA floppy drives, such as THIS one?

    Try it! If it doesn't work, try a null-modem connector. I doubt you'd need to go so far as to use breakout boards.

    At the absolute worst, you could probably find all the original signals on the...

    That is RS232 serial. The Compact Printer, IIRC, runs off of 2400 baud serial, rather than parallel.
    Consider THIS pinout of DB25 RS232. Pin 1 is ground, pin 2 is transmit (from the computer's...

    mAh, or milliamp-hours, is a measure of capacity, not of current. An 1800 mah battery can supply 1800 milliamps (1.8 amps) for 1 hour, or half that for twice as long, or double that for half as long,...
  17. WTB - Toshiba Libretto dock and/or floppy drive

    Title pretty much says it all.
    Got a Libretto 50CT off Ebay, but I hadn't considered how few thingies it has, and now I need a way to transfer files, unless I can somehow boot off the IR blaster. ...

    Shipping won't be a problem for me; I'm going to be there. Dead battery almost goes without saying in these things, though the screen disability is worrying. Have you a picture of it running?

    That DG sounds interesting to me...
    I recently got a Digital Computer Controls D-116, apparently an almost exact clone of the DG Nova 1200. Irrelevant perhaps, but I also really like DOS...

    Huh. I sit corrected.
    Apparently, according to CPU World, it also has some instructions from the 80188, another CPU I did not know existed. Which explains why I was able to run Monuments of Mars...

    I don't think I have specifically an 8086 system, but I do have a Zenith system (EaZy PC) which has an NEC V30; basically the 8086 version of the popular NEC V20, used to replace 8088s. I could run...

    Typo on my part. It is a 1.




    No. What I presume is the ROM chip is marked:

    I could be interested in picking some of this up.

    Never had a mini before, but I'd be eager to learn! Teletype looks tempting too. : )

    The MFM controller is a Western Digital WD1002A-WX.
    According to the board "jumpers" (the ones in question are connected with a PCB trace) and stason, it has a 32K ROM. However, CheckIt tells me...

    I think I agree. After some experimentation, it appears to be a ROM conflict: when I disable the ROM BIOS of the MFM controller, the XT-IDE gains functionality, and when I disable the ROM BIOS of the...
