    MCLV20_Max / MCL86+ as a debug tool

    This looks like a good candidate for another project. You could write a generic diagnostic pre-POST system especially for the MCL86+/V20 that could give the 5150 a verbose POST mode. The Teensy could check out the system at top speed and then pass control onto the normal BIOS POST. This way...

    Open source equivalent of INTERLNK / INTERSVR

    Here's the source code to another programmer's net-based Interlink like program: https://github.com/jrohel/NetMount The work is inspired/based on etherdfs.

    Drop-in NEC V20 CPU Emulator with EMM and MicroSD - MCLV20_Max

    I would think that hooking into the warm boot routine and automatically switching to ACC1 before proceeding to warm boot would be the best way to do this. Perhaps it would even be feasible to have the Teensy code do this automatically.

    PartUtil: Dual boot DOS without a boot manager

    Thanks for making this available with the source. It reminds me of an even simpler program that allowed you to dual boot between DR-DOS & MS-DOS. But where is the source code to your original's big brother? ;) Isn't the "lot of features" you started adding worth sharing too?

    Making Your Own Kaypro Replacement Parts

    Thanks for the work you've put in! These parts are hard to find. (I'm not even sure they're still being made.) I've never been able to verify this, but I believe these power cord holders are used for most or all of the Kaypros. They certainly look the same as the ones I've seen on the Kaypro...

    Is COMPUTE!'s Gazette really being revived ?

    Oh come on. Be honest, you're only interested in something like this because it showcases your heritage in the Upper Triassic. :) (Was that one of your relations on the cover?)

    what makes you use cpm

    I'm amazed every time this topic comes up! First of all, the order of the parameters is a question of "which makes more sense to which user", not which is "better." English speakers, for example, find SOURCE and then DESTINATION more natural because English also orders them that way. Speakers...

    Joystick crashing

    If you really want someone to help you, ;) don't lie to them like that! ;) Or like that! :)

    Joystick crashing

    @tech58761 is on the right track, I think. Personally, I've had this same problem and it was what @Ruud said could happen. Do you have another joystick or another computer with an Atari style port you can try?

    Well, it looks like you've generated some interest now.

    Can a very early PC BIOS boot anything other than a diskette drive?

    It seems to me that a straightforward approach to using this HD-controller-masquerading-as-a-floppy-controller idea would be to have the drive provide the PC with a minimum of two drives: one a bootable virtual floppy and the other a "regular" HD. This is similar to the approach some external...

    Warning to Posters on this Forum: TRIANGLE SCAM

    I don't think anyone meant to even imply that YOU were a scammer. I'm sorry if what I wrote gave you that impression. Sorry to hear that. I've been there and I know how it can affect you. Understood. Knowing your own problems is half the battle, as they say. I'm glad there are no hard...

    Olivetti M24/ AT&T PC 6300 Keyboard Disassembly

    The secret is that the keys can be removed by themselves. The keyboard doesn't need to be opened to be cleaned. Using a small screwdriver, carefully pry under a keycap until it comes off. (Two small screwdrivers on opposite sides of the keycap can help lift it off the key more easily if you...

    Can someone translate the Japanese documentation for this DOS REXX software?

    That's what I wanted the (human) translation for, to find out. But, from the Google Translate output, there is enough understandable English to be certain that REXXD is a memory resident program that intercepts the command line from COMMAND.COM and checks to see if a batch file is about to be...
