Vax is hardware. VMS is an OS. Unix also run on vax. VMS is a fairly
conventional albeit complex file system that can do sequential, indexed
or random accesses. It deals with files, directories and volumes.

<>find fragmentation a nightmare even on Linux.
Some file systems do more poorly than others with fragmentation. For the
best fragmentation is a mild performance hit, in that it will take more
disk seeks to find all the peices. For others (RT-11, NS*DOS)
you can have an almost empty disk that is effectively full as the OS
cannot allocate space peicemeal. VMS, DOS and CP/M perform well with
fragmented files.

On the bottom of the Mac Portable I have sitting right here, it says 7.5v
2.0a. The injection molded plastic never lies... or does it?
This is a model 5120, non-backlit. Maybe the backlit version took 1.5a?

Anybody have any of these? Any experience with them. I would love some

To quote the 2nd edition: "While Outbound continues to floursh-thanks to
a wisely-forged legal agreement and clever positioning of their Macintosh
portable versus the Apple PowerBooks-I question their long-term staying
power."

In general, I've found that things like TVs are almost never repaired,
at least in the US. Back in the USSR, we repaired everything,
including alarm clocks destroyed by trashy batteries that leaked.

Do you mean you've never left a problem unsolved or never left a

Again, the original was 1.5a, which was not enough to power the
machine w/a dead battery. 2.0a came w/ the first powerbook, and works
fine.

Gotta be 2.0a though, at least that's what it says on the bottom of the unit.

that works off of 4 c batteries. No power came with it, cost $10. It has
CP/M 2.2 in ROM from DRI 1982; Bios date is ver 1.0 1984; has a built in
modem 300/1200; software in rom is WS, CALC, TELCOM, and FILER. This baby
powers up very fast and seems work very well. I even put in some PIP commands.

Likely not, never tried it's stripped some. It was also used to push the
idea of device independent page descritpions that were capable of text and
graphics. One product that came from that was RETOS (ReGIS to Sixel)
translator. I later modified fancyfont as part of runoff to give font
capable runoff with bitmap output. It could really give a disk a workout.
