    You mean that some programs "can" use EMS; MSCDEX doesn't require EMS by any stretch. Generally, on my MSDOS 6+ systems, I load himem.sys and don't bother with EMM386. MSCDEX can always be loaded...

    I find that getting the corners right is a big help when doing larger (>=144 pin) TQFPs on 0.025" pitch. If I don't, inevitably something shifts slightly and I end up making a mess out of things...

    This thing?...

    This thing?

    At best EMS was a kludge (I wrote for it). When the 386 came along, it was pretty much a dead topic.

    That looks right--you can copy over (in this order) IO.SYS, MSDOS.SYS and COMMAND.COM and you'll have a bootable floppy.

    If the .SYS files aren't visible on your hard drive, you can use the DOS...

    Does this work better than placing the component in some solder paste and zapping it with some hot air?

    But yeah, using a fine tip to stick down an SMD (especially things link fine-pitch TQFP...

    Are you certain? One can always copy over MSDOS.SYS and IO.SYS and COMMAND.COM manually.

    I saw those guys early on. My customer would prefer that the discs not leave the country.

    DOS 6.22? Try FORMAT A: /F:180 /U

    Otherwise, DOS will try to use any format already existing.

    There isn't even a standard tip setup within brands. For example, the Weller TCP tips fit only the TCP iron. Other Weller models use different tips.

    Depends on the model (there were several). But the models with the built-in acoustic coupler could be operated either as a CL/EIA interface terminal or with the coupler. e.g. the tech manual for...

    If you don't mind running MSDOS look for COTDOS on SIMTEL20. It's a device driver that allows standard DOS access, and formats using the standard Apricot boot sector. You'll need a 5.25" 1.2M or...

    Depends--is it operational? Recall that it does use thermal paper, so an intact printhead is very important. I think that you can still get thermal FAX paper.

    Then there's the model. I'd...

    There should still be quite a few TI Silent 700s around. That was probably the most popular portable one.

    I didn't like the angle of the screen and the non-detachability of the keyboard. I could live with both, but there were better choices.

    The naked keyboards were available NOS on the surplus...

    I doubt that it makes much difference in most cases. IIRC, the original XT-IDE used LS373 latches.

    I've wondered myself if the XT-IDE could be re-done using a 74LS646 bus register. Probably--but...
