  1. More Versa Work.....

    Just got the Ultralite in, I got a REAL basketcase, lol. Rusty oscillator, looks like water damage, ticks when the battery is installed, no status on the LCD display, LCD panel thrashed but control boards good, AC Adapter is down for the count as well, and the plastic is cracked. When they said "for parts" they were not kidding. Managed to use a few parts to fix the M/75 I just got.

    The M/75 was also a bit of a basketcase - overpaid. But the chassis on this one is flawless ...

  3. More Versa Shennanigans......Cool Idea to rehouse the M/75

    So, while the M/75's case is crumbling like Feta Cheese to the point I can't use it anymore (that's why I said it "died") - at least not in it's current state.....I got a crazy idea......old computers don't come to the Creeping Network to die, thjey come to the Creeping Network to be reborn as something better than they could have been in their time.

    The #1 problem with all these vintage laptop computers is the darn cases. I've owned about 10 of them, and they would make ...

  4. M/75 Is Fixed, SHSUCD Shennanigans.........

    Well that was a long wait on stuff......NOT

    Turns out I just knocked the power board loose when I Dropped it.....so I added additional insulated foam support inside the case....that thing isnt coming loose again.

    So most of my tinkering since has been with the SHSUCD suite of utilities for optical drives in DOS. I'm doing all this under FreeDOS 2.1 for the time being (really tempted to put RC 1.3 on though).

    So anyway....I've got five or so game's I've ...
  5. M/75 Dead, My Explorations in Board Level Repairs, P/75 as main?

    So last night I was playing Hoyle Soliatire on my NEC Versa M/75 and of course somewhere along the lines I had to move, screen shifted, and then the computer shutdown and would not come back up, acting fully dead. So I guess it's time to do some board-level 486 autopsy. Kind of a shame, that was my favorite one, but I guess the P/75 has not been getting enough "love" lately so I'll tune that one and tweak that one, plus give it a chance to be a FreeDOS beast, and maybe also bring the ...
