    Consider a TSR that is lazily programmed. It hooks some BIOS interrupt. It can't invoke the original BIOS routine with an INT anymore. Of course the proper way is to store the old address and call...

    The method I have found to be most compatible with "modern DOS" (including NTVDM) is a combination of Int 21/AX=4409h (IOCTL - Check if block device remote) and Int 2F/AX=150Bh (MSCDEX - Drive...

    Are you using a PC/XT keyboard? AT keyboards will plug in but not work.

    Once you get the keyboard working, typing "key on" will turn on the function key display.

    You can also increase the sample rate of PS/2 mice to 100hz+ to get a smoother cursor. Serial mice usually max out around 40hz. I like the concept of an add-on PS/2 port, I just don't think there's...

    It's open source, you can print your own PCBs. As has already been stated, DIN connectors are too large for expansion slots. You can go MiniDIN, but you still need special adapters or cables. So...

    Cool stuff. I find an EPROM emulator is very useful for test and development on real hardware. I use a Moates Ostrich 2.0 which is geared towards automotive tuning but works with any binary image.

    3.5 and 1/4 TRS inputs on consumer gear are usually unbalanced, which means noise...make sure you get something with balanced inputs, preferably XLR. Don't waste your money on a Sound Blaster.

    The 5150 uses 2364 chips, which are incompatible with the 2764 used in XT clones or the 27256 used in the 5160. So the user can't be completely clueless and needs to know what system he has when...

    What model PS/1? I use 72-pin FPM PPD in my 2133. KTM-0130 is the Kingston 8MB version and there are several on ebay right now. IBM p/n 92G7203, 92G7520, and 92G7202.

    I understand your perspective. My point is it's misleading to state the age of the deceased in the present-tense. Mozart isn't 35. He was 35. You aren't older than your parents. You are older than...

    You remember him as he was at age 17, sure. But you would never tell someone "my brother-in-law is 17", because that would lead to the assumption he's alive and your sister is a cougar. :p

    That's a strange way of putting it. Mozart no longer exists and therefore is not any age.
