Actually, mine was maroon, although the slipcase was gray; and as for "Not
yet a classic," the pub. date was of course 1984. You'd be welcome to mine
if I still had it, but I don't....think.... I do.

While moving the 11/34 to a more lighted area, I broke the power switch
off the back. Now it doesn't power on. I need a WHOLE NEW POWER SUPPLY!
Damn! I hate myself sometimes!
That was a Stupid, Stupid, Stupid Mistake!

What the hell.
I used to work for DEC and DEC didn't sell ALPHA they sold the fab unit
that does alpha. It's cheaper to have some other silicon foundry make the
part to your spec. WD, intersil, AMD and Harris have over then years made
parts for DEC that were designed by or for DEC. DEC plans to keep cranking
the Alpha for bet your business systems than PCs have fallen short for.
In the mean time I'm running a few old VAXen to remind me how much better
an OS VMS (OK, OpenVMS) is.

Hi folks. I picked up a Tandy Model 100 laptop computer from a local
thrift store a few days ago, for about $9. So far so good, but it doesn't
have any ROM's in it (both sockets on the bottom of the machine are empty)
When I switch it on, then off , the "Low Battery" light flickers, but
that's all (the LCD stays blank)
So, are these ROMS (which I think I need) something I can still order from
Tandy (without paying an arm and a leg)?
Thanks in advance (Oh, and I saw, but didn't buy, an Amiga Joyboard . . .)

> I just passed on the optical mouse and some keyboards for the Sun's.
Passing on the optical mice or keyboards (type 3 or 4) is no great shakes.
However...
Passing on Sun optical mouse pads for type 3 or 4 mice is a crime
punishable by death. They are unique _two_ color pads (the horizontal
stripes are a different color from the verticle ones) that Sun does not
make anymore (contrary to Sun Direct's sales people, the pads they sell
are for the normal type 5 mice).
In short, the things are getting quite rare.

You can boot the thing off a network - no local disk required.

I remember when I wouldn't take a 286. I needed POWER. Like a SERVER.
How 'bout a 486??? THAT WOULD LAST UNTIL THE 21st CENTURTY TOO!!! IT COULD
RUN WINDOWS 3.1 with NO RAM ERRORS!!! And then when upgrading to Windows
95, I remember the guy there specifaclly falling down laughing, resulting
in purchasing 16MB of RAM (Then at $10 a MB), to add to the 12 I had, along
with a 486 DX/2 processor. I doubt that the 432 would actually take it.
But I think that Intel aimed it at the wrong market. The Digital Alpha
(Recently aquired by Intel, with it's RISC... yes, RISC technology) has had
some success, with 600 MHz of power in a single chip and x86 "translation
software" written by Digital. Also, there is a version of Windows NT 4.0
made ONLY for Alpha's, so the translation software is not used there.
Microsoft writes programs like Internet Explorer for Alphas, but they're
usually "a month late". Intel might have just bought it to stamp it out,
but my guess is they're aiming to do something with the RISC market, they
could be attempting to lower the Alpha's power down to H/PC levels and then
WINDOWS CE. Maybe they'll take the 300 MHz version, that was avaible in
1995. If Apple can get 150 Mhz into a handheld, why can't Intel? But back
to classics. Would the 432 be capible today if it were given a second
chance?
One last thing. I remember something about a huge warehouse filled with
classics. Has anyone heard since?

fast parts...
keep this in mind: Good, fast, cheap, pick any two.
In 1982 NEC and Intel sold 1kx4 (2149), 4kx1(2147) and 16kx1(2167) these
were static mos parts that were anywhere from 35ns to a slow 70ns. They
were widely available and about 7-9x the cost of the 4116 16kx1 dram. The
problem was that '83 brought 64kx1 parts that were as cheap as the 4116,
faster than the 4116 but were about 270ns-Tcy/200ns-Tcas. When your
building a system the 4164 (8 of them) used roughly 240ma. the same memory
using the super fast 2167 (32of them) would eat a whopping 2.16 Amps! Speed
costs! It would also produce more heat.
In late '83 I built a system using a 8088/8mhz with 256k of 2167s besides
being amazingly fast. However 128 of those 2167s tended to heat up the
place and their cost was $768 compared to $128 for the fairly new 4164 and
the $96 for the very new 41256. Also using the newest 256k part would fit
4mb of ram where 256k of static parts fit and still use less than half the
power.
By 1990 32kx8 static rams were in the sub 30ns region. Drams were fairly
fast for page mode but their requirement to have the address stuffed in in
two pieces will add time to the ability to access in exchange for power
savings, pins and packing density. Dram was never as fast but usually
their density was the win. For the current generation of 200mhz and faster
systems cache is barely able to keep up. look at the cost of 16mb of dram
compared to 512k of fast cache ram.

Anybody have any information pertaining to a Visual Technologies unit # Visual
1083? I think its also called a "Commuter".
Thanks in advance.

1. Depends greatly on where you are. (TI & Tandy common as dirt in Texas,
less common in, say, Bahrain.)
2. Depends greatly on the audience. (Common bloke: Apple I, Osborne 01,
Altair, a couple others. Me: Atari Portfolio, Model 100, NEC Starlet,
Outbound Laptop, etc.)
I would seriously recommend checking around on the web for the various
virtual museums out there. If you don't know where to start, try
