Does anyone know how to access the BIOS of an old Toshiba 2200sx
laptop? It is Pheonix, but I can't tell what version, etc., as it
flashes on screen very fast. I need to set up the COM ports of this
thing and can't seem to figure it out.
Any help would be greatly appreciated!

I know, Ive done it before, the back panel is not a pretty site
afterwoods.............
I remember a program, actually a sound driver, that was written for
computers without sound cards. I think it was intended for Windows
3.1 or something like that to allow simple .wav files to be played
--- in lue of a sound card -- simply used the internal pc speaker.
If you have any information on something like this, could you respond
to me via private e-mail?
Thanks,

Greetings,
I saw a very large Wang box at a thrift store yesterday, I *think* the
little sticker on it said "PC-002". I didn't see the keyboard, but I
didn't look.
The machine was really big, I think about twice the height of an old
IBM-PC and about the same width. It was longer than it was wide.
It had two full-height 5.25" floppy drives.

I know this isn't a 'vintage radio' list, but . . .
So, were you in the Motorola camp (Twin-V, T-Power, Motrac, Motran) or
were you GE (Prog Line, TPL, Mastr? Or possibly one
of the few in the RCA arena (CarFone, SuperCarfone, etc.)?
I was Motorola, in the Mid 80's myself . . .

I'm one to both restore and modify. I ahve two CCS s100 systems one is
stock and the other is in the proces of recieving some mods like a IDE
adaptor. Why? The second is sans hard disk and for what I do it would
be a nice box with a hard disk as it's small. it's also reversable as
the front pannel that will also be modified will really be a new one and
not the original one.
If I had a PDP-8 and no disks I'd likely make a IO interface for a modern
drive becuase PDP-8s are easy to hack that way and it's also reversable.
The real trick would be using whatever micros so that the new disk
interfaced and behaved like an older one so I could run old code as is.

It can be done on most CPUs no matter how small. Dynamic multitasking

same.

LN01 training, I goosed the trainer that I could create a fault he

going later. the bug, lead pulled off the fuse holder in the main PSU.
I earned my keep fixing commercial VHF and UHF radios which from call to

Considering the size of the data file and the DVI result... floppy? Nope.
Hard disk or large ram disk(1mb better).

Bit of a different note here. I've got someone that is interested in
shipping me some RL02 packs for my systems, but is concerned about packing.
Does anyone have any advice on the subject.
Well if they arent keeping it, it should go to a museum like the one at
Boston.....
One question though, wasent the Xerox 820 basically the same as the Alto?

A few months ago, PC World did a similar thing, only they made real
hardware problems. Cutting the IDE cable on some machines, and
rearranging RAM in others (so the SIMMS were no longer paired). Noone
solved this. Better yet, the next issue, they published a letter
saying that these were clearly artificial problems, and I quote,
"IDE cables just don't fail". The guy said that a tech would never
think to look at it.
BTW, do you train service techs?

Ahh yes, the Minifon. Yes, it's off-topic, but it is/was indeed a cool piece
of technology. German from the early 1950s. Wire recording had all but died
out, but this machine was smaller than any TAPE recorder, so there was a
niche market. Yes, it was used by spies, law enforcement, and such. (There
was a version of the microphone built to look and be worn like a
wristwatch!)
It used subminature tubes 1 1/2 inches long.
If you find a 1953 Allied radio catalog you'll find it listed for sale there
for $289.50.
A transistorized version of this wire recorder was being built after 1960!
There's some info on this and about a zillion tape recorders from the 1950s
and 60s in a book called "Evolution of the Audio Recorder" by Phil Van
Praag. A book I thought I'd never see written - I guess it took an old audio
technician to write it.

nice to know there's still some Tower users about - there seemed to be
quite a following a few years ago but interest in them seems to have
dried up (although there's probably a few posts to comp.sys.ncr still -
one day I'll get proper Usenet access here :)
do you know if NCR (or AT&T, or whoever's responsible for these things
these days!!) can still supply OS tapes? I got my '700 with all sorts of
software on the disks - the guys it came from we in to developing
programs for X-windows so there's quite a lot of cool stuff on there.
Sadly no OS tapes and no manuals (I borrowed field service manuals from
someone a while back so have all the useful info from there).
mind you, last time I tried to power up the machine it was completely
dead. I only had a few minutes so checked obvious fuses etc, but without
any luck. Hopefully something simple - I don't fancy trying to trace a
fault on one of those system boards :*)

<But there's a difference between a Z-80 running a text-mode interface,
<and an 8088 running a GUI. Also, remember that Bill Gates didn't know
Not much. Some z80 systems were faster, considering by time thge 4.77
mhz 8088 was making inroads around 84ish the z80s were cranking at
8mhz some faster. Also the 8088 was anout the same efficientcy as the
z80 for byte data. There were a few z80 system with 128k or more of ram
running at 6mhz around the time of the PC introduction.
I have a Visual1050 (early 1984) that is z80 128kb ram and GUI capable
running CPM and GSX-80 all competing with PC GUI systems. Nice box with
10mb hard disk and two 400k floppies and mono monitor.
<very much about operating systems, as opposed to languages. MS Windows
<is the only OS MS programmed ground up, something they only started
No. The internal file system (disk operating system <dos>) used on the
TRS80 disk basic was amoung the many that preceeded it that was before
1979. The file system was FAT based.
<after the A1000. And, I've never seen Windows multitask under 8MB in the
<way the Amiga or a UNIXoid computer can.
W3x was not preemtive nor very good coopertive multitask. And even
with 32mb didn't change that. It would take w95 to get to that point.
CPM in the guise of MPM was doing for years by then. I'd also had CP/M
multitasking in 64k in '81. No majik.
There was also multiuser basic for Altair and NS* had a multiuser version
of the NS* OS.
<>> and Gates replied that multitasking really wasn't possible in
<>> anything under 8 megs of ram. To which the same reporter replied,
The PDP-11s running RSTS (or TSX-11) in the 70s didn't multitask
either... sometimes with several dozen users usually in 64kb and maybe
256kb of ram. But heck the PDP-8 was doing in before that in 8kw (RTS-8
or os/8). Of course if you want something modern that can multitask in
less than 8mb VAX/VMS (runs fair in 4mb!).
