For years, it was *THE* disk operating system if you had a 6800/6802 based
system. Originally written in the late 70's, it powered the majority of
the SS-50 computers until the 6809 came out. Then came FLEX/09, StarDOS,
UniFLEX, OS/9. . . .
There were other (some better) DOS's that were available at the time from
Smoke Signal, Moto, and a couple of others, but FLEX gained alot of support
>from developers, and had alot of applications. I'm trying to get one of my
s-50's working again so I can play with FLEX (I won't settle for emulation
when I can have the *real* thing).
It was a bit limited, but it was small enough to fit within the 6800's 64K
address space, with *plenty* of room to spare!

Well, yeah, but still faster then 1Mc (or 800kc if you didn't modify the
cpu board).

Umm, yeah, but being a 6800 enthusiast, this carries with it some
especially interesting possibilities!

Yes. How the implemented the microcode would be of particular interest.

It's most likely the same as the Mac Portable's power adapter, which is
7.5vdc, 1.5A.
Paul Kelbaugh <kelbaugh(a)aol.com> has Mac Portable power adapters for sale
for around $25, I believe.

Nah, these were frenchmen, (independents) known throughout the state as the
best in Citroens. That's all they did. They had no problem working on the
citroens and keeping them running.
I, on the other hand, couldn't understand the inner or outer workings of
those vehicles. I still think that whoever designed 'em must have been
jealous of swiss watchmakers, but with all the design skills of the
samsonite gorilla.

Yeah, but you have to remove the (rear) fender to get the wheel off, (I'm
not kidding!) and who wants to do that when you've got (what I at the time
considered) a major celebrity in the car? I limped along back to Moscone
and dropped everyone off before skulking off to a nearby parking lot...
P.S., I still have scars on my right hand from another time working on
those #$&*@( things... Give me a Land Rover any day! 8^)

Still in need of a few microchannel (for PS/2) ethernet adapters with
the BNC 10base2 setup. Doesn't matter if they have AUI or RJ45 with it
as well, as long as it has the BNC/10base2 setup. I don't need 3270
cards so check any cards you think you have with the BNC connector to
see what they are.
Looking for donations, trades or reasonable priced cards for a parochial
school network project that's overdue. I've gotten a few good reponses
and have a couple on the way but I'm going to be about 4 or so short
yet. I've also gotten one or two ridiculously high quotes for used
cards. This is a project on a shoestring budget so no $30 or $40 cards
please.

Here's a question... I get a lot of laptops minus their PS's. The ones
that are 12vdc or 9vdc with a standard plug are no problem, but the ones
like the outbound (I'm lucky enough to have a PS) or the GRiD's (17.5vdc?)
or whatnot aren't even covered by the select-a-warts from Radio Shack.
So, does anyone make a box where you can set it for whatever voltage you
want from, say, 1vdc to 50vdc or something, with some way of hooking up
different plugs? Does anyone know where to get such a beast *cheaply*?
Thanks...

Hi,
If any of ya'll out there are interested in a Kaypro 4
"suitcase" computer, I have one on the ol' "trading block".
The machine itself is complete and working but I do not
have any diskettes for it. On power up it displays a
"please insert system diskette in drive" type of message.
Per my previous postings I'm mainly interested in
calculator stuff (and have a detailed "want" list on my
Web site). Please write me directly if you have any
interest in this machine.
Regards,
Alex

You could use a camcorder or camcorder charger to charge the battery. It
would be a lot safer. You could overload the supply if it's not the right
volt/amperage, worse yet, you could blow something in the computer.
