Very interesting. Are the approx. 6 rows X 20 "modules" relays? Looks like
something that could be built without too much difficulty.
I assume you have it to have made the scanned image. Have you powered it?

In the case of file viruses it only needs the CD to contain an affected file.
In the case of bootable CDs all it needs is for them to be mastered on an
infected PC. In theory they can act just as well as vectors viruses but, of
course, it is less likely that you will get a boot sector infection from one

fdisk /MBR is very dangerous unless you are absolutely sure what you are
doing. If the machine is affected by any virus which moves or encrypts the
partition table then this method will lose you all of your data. The same
will happen if you are using any disk remapping software such as DM to get
around size limits.

If I understood, this could be summed up as:
When an interrupt happens, the interrupt line is pulled low by the
interrupting device. If it's edge triggered, the CPU can't tell how many
devices are causing the interrupt and only services the first one.
And are you saying that if they were level-triggered, I could have two
devices on IRQ 7? And is it easy to design a level-triggered equivalent
to the PC on paper? Are all PS/2 s level-triggered or only the MCA ones?

Yes, I've noticed that too. All variations on a theme. Except the GUIs
which are somewhat more variable, and the BASICs which often come up with
different ways of accessing drives.

I've used Caere OmniPage in the past, and it seemed pretty good, but
I wasn't trying to scan old computer docs, just nice typewriter pages.
I'm very interested in the collective wisdom about this, so of course
it seems quite on-topic to me. I'd like to scan the ASR-33 Teletype
manuals, which contain plenty of odd hand-set type, drawings, off-size
pages, schematics, etc. I'd also like to restore the UCSD Pascal
manuals, of which I've heard the only electronic copies at UCSD were
lost a long time ago.
Given these problems of line art and odd character sets, I suspect
the most useful first step would be to scan all docs at a given
resolution, then store them as bitmaps in a format most easily
loaded into any present or future OCR / PDF-ish program. Someone
mentioned the multi-page TIFF format. As for which resolution,
I think 300 DPI might be too coarse.
I like Doug's idea of shooting for HTML. I recall the multi-res
buttons on IBM's patent server, which allows you an easy way
to browse thumbnails, then zoom in on the desired page at various
resolutions. Is there an off-the-shelf tool for doing this?

Actually, Netscape still goes wacky with 32 MB RAM, and a 4.3gig HD on a
P200. I think that some of the free browsers (IE, Opera, Mosaic, even
NETTAMER) outperform the overpriced netscrape.

two notes here:
you can use the /mbr switch, but if you are doing it off the hard drive, its
useless. of course you'd have to boot off a clean floppy. i know in the case
of pcdos7, sometimes you can run ibmavsh.exe which will immobolize some
viruses like the D3 one. in that case you can run ibmavsh, run /mbr and then
cycle the power and it's clean. in the case of monkey virus 2, if you run /mbr
you'll lose everything on the hard drive!

The SpectraVideo series, particularly the SVI-328, had a version of CP/M
available and lots of CP/M software (languages, Wordstar, DBase II etc) were
available from Spectravideo for this unit. The SVI-328 was not quite MSX
(but it was what Kay Nishi based the MSX design upon). The SVI-728 was a
pure MSX machine.

Nope. It was IE. It was back when the Internet was just starting to be a
big thing. I think maybe 1993 or 94? I saw it in an article in an old
computer magazine (PC-World?) article that was comparing OS/2 browsers.
There was IBM's, IE, Netscrape, and a few others. I knew it was a while
ago, because how many articles do you see comparing OS/2 software anymore?

I ran 1.4 and it was cranky. the next version I used was 2.0 better and

O.K. I decided to use my TRS-80 Mod III to type a story (about 100 pgs or
so) that was an assignment for my Communications class in school because it
has a good keyboard for lots of typing, and it has a clear printer. I get
it all typed up (three SCRIPSIT files), switch on the trusty DWP II, and
start printing. As the first two pages are done, I reach onto the shelf
(above the computer) to get a paperclip to hold the whole thing together
when it's done. Now the paperclip that my hand happens to grab is secretly
joined to another paperclip, which (naturally) decided that it didn't want
to leave the little cup they're all in. The whole thing spills out, sending
9 of them INTO the computer.
The screen blacks out, printer stops, I hear two sharp pops, a puff of
smoke, lights dim, and I hear the snap of the circuit breaker from across
the basement. I say a quick string of explicitives directed at the
paperclips while I'm searching for the flashlight, which (again -
naturally), has dead batteries. I start pulling all the plugs in the area
of the computer, and carefully make my way to the breaker box. I find the
tripped switch, flipped it back on, and went back over to the computer,
which was surrounded in a bit of a haze.
I grabbed a screwdriver pulled the case apart, removed the paperclip that
was shorting the main power transformer. I plugged it in, and turned it on
(at that time not knowing that 9 paperclips had went in). Smoke bomb.
White smoke was pouring out of the M/B compartment. I removed the cover and
found the other 8 clips, one partially melted into the Z80. The serial
board was almost totally black (never worked anyway). I was thinking four
words: Why me. Why NOW?!
Naturally, I have a spare P/S board, video board, and floppy controller, but
no spare M/B.
Does anyone have a spare board that they wouldn't mind selling for a couple
of bucks, or I could take it off your hands so you don't have to throw it
out :) My board had 48k RAM. Or was it 32? I forget, but it wasn't 16,
which is what the case says. I don't really care how much it has (16 will
run SCRIPSIT, won't it?), and I probably have chips laying around that'll
work in it, anyway.
If anyone has an RS-232 board laying around, I may be interested in that,
too (not a rush, though), so I can connect the 300baud acoustic modem and
have the "world's slowest computer connected to the Internet" :)
ThAnX in advance,

the way i understand it is that the pc interrupt system is edge triggered. i
think an interrupt went low only momentarily and if the machine happened to
overlook that interrupt, the machine would hang. on the ps2 models, the
interrupts on that are level sensitive, meaning that an interrupt request goes
low and stays low until it's satisfied. there is much less possibility of
level sensitive interrupts going unnoticed. ps2 models can also share IRQs.

It was free for educational use (including home users) since at least 1994,
when I obtained version 2.something to replace the 1.01 that was on the
machine I was using then. IIRC, you were supposed to register it, but
there was no fee if you "signed" a declaration that you were in education.
I remember that the download was a massive 2MB and I had to split it
across two floppies...

Last time I checked on it, Netscrape Communicator was somewhere around $45
in the stores, where IE was free with about 10 different programs.
Netscrape came with the program that I bought, and it was a stripped version
that kept wanting me to sent $30 to Netscrape, and it stopped working after
6 months (date stamped). Let's see...IE only wanted me to sign up with MSN
once, and that was because I used an MSN trial CD to install it. First time
I ran it, I simply went into the settings, set the start page as blank, and
Bingo! no MSN. If you ever noticed, When you got Netscrape on an AOL CD,
it _really_ wants you to sign up for AOL AND pay $30 to them.

AS to which is better, neither when broken and both when working with one

Huh? The solder melted in a lot of the places, and the paper clips stuck to

Ah, not really. the production start dates for both chips are within two

cost of 8bit wide everything but still needed more performance than the 8085
could deliver and also gave a migration path for those that grew out of the

The 8088 and 8086 were both second sourced before IBM did the XT. thats

Yes. I've been using a 386DX with 128k cache with Win3.1 and Netscape 3.0.
Doesn't seem significantly slower than my friend's P90 with W95. Sometimes
Netscape crashes with some .JPG files (GP fault in the VGA driver) and I
have to start over.
Haven't tried much newer, it doesn't seem right to require a 300MHz
processor and 64MB ram to mostly read email, much less type mail messages!
I did adjust several things, like remove smartdrv's "buffering" for the HD, etc.

Okay, so it's a little new for the list...
Next week I'm going to try and finally rebuild the 80386SL-based notebook
that's been a pet project for a while. Since I'll have it open, I thought
I might go ahead and install a math coprocessor. My only question is...
which one?
The 386SL was Intel's "notebook" CPU. Does it require a 387DX, 387SX, or
something else altogether? If it's the 387SX, can I use a Cyrix FastMath,
as I have a spare.
Thanks...

No clue. It was back when OS/2 was one of the "good OS's that I didn't

My first view was from the cover of the October 1978 Popular Science:
http://www.goldrush.com/~foxnhare/PSPETSM.JPG
The PET there was obviously one of the prototypes (note the rounded case, from
what I understand it was wooden, also note the cheap wood-grain contact paper
over the case. kinda looked neat though.)

Yeah I think that sums it up for most of us classic computerists... (grin)

Yes it does; so far so good. (Never seen a white trim myself unless you are
referring of the plastic frames on the later plastic-cased PET models (there
was still a black trim around the picture tube though.)

Many stealth viruses can hide from virus checkers as well as not showing the
memory they occcupy as used. When you ran the scanner did you boot from a
_known_clean_ write protected floppy, this is essential for reliable scanning.
Also, you do not say what virus scanning software you are using bear in mind
that MS anti virus doesn't detect many common viruses.

Oh. I didin't know that. You've got one of the cassette models. Wanna
sell the M/B??

I think I've narrowed it down to the controller being the problem. I
remember seeing somewhere that the WD-XT-GEN won't recognize the original
ST-506. I'll have to try it with another controller sometime, and if it
doesn't work, I'll try to find another HD.

*One thing I ASK: HOW come those clips can slip in those slotted
*vents (it's blocked by screening too!) and trap into their deadly
*short circuits act on that _VERTICAL_ board?! I thought that would
*be more possible if the boards were horizontal.
Well, there was no screen on the vents in _this_ TRS-80. Also, when I got
the computer (it had been in a flooded basement), the rear CPU board
shield/cove had rusted fairly bad, and when it was on, the computer wouldn't
boot, so it wasn't there. I'm not sure of the exact path the paper clips
took, but once they hit electric current, they stayed there. The one that
fell across the 120v main PSU power connector actually fused to the
connector, and I had to use a wire cutter to remove it.
*That is what I'm talking about in those silver-grey clamshell with
*9" mono monitor, space for 2 5.25" FDs, orange reset key, great
*keyboard, cutouts for 2 extra add on cards to interface with outside

*underside.
Sort of. It's got a 12"mono TV tube in the case. Clamshell? Isn't that
what they called the Zenith laptops? Or are you referring to the color?
Mine had the two floppies, and the two cutouts for the add-on cards were for
serial and floppy (serial was optional, the floppy one was just the bottom
of the FDC). Mine had both, although the serial card (which never worked
right) is a charred mess. I'm not sure how it happened, either. There
weren't even any paperclips in it.

I did. I'm using Mac PPP, with System 7.5. The program still wants an init

I just make sure nothing is writing to the disk and switch off. If
everything is idle just kill it. I have never had one come back to get me
in over 18 years. This works if you are the only user.

Just throw in any old 360k drive. It'll work. Mine had one original TRS-80
drive, an IBM drive pulled from a PC, and the external drives were an IBM
4869 with a toshiba 360k drive pulled from a Leading Edge duct-taped on top
of it, using the 4869 P/S. The controllers for the externals were salvaged

On RT-11 does DUSTAT care what kind of a disk controller you've got? I
just spent a bunch of time fighting to get it onto my RT-11 system only to
find out that once I got it assembled, it doesn't like something about the
system. I suspect it's either the WEQSD ESDI Controller, or the ESDI
drives I'm using. It gives the following error:
?DUSTAT-F-No translation for this unit! (?)
Or am I confused and using the wrong syntax?

Probably. No paper clips had fallen into it, and no signs of external
damage. I really won't know if it's good or not 'till I get a new board.
Even if it is blown, I have a good, spare one.

It still turns on, but makes the CPU board seem more like a fog machine than
a computer, and it stinks up the house pretty bad.
I have a scope that someone was going to trash that appears to work, but I
don't have any cables but a couple of old multitester cables.
I doubt there would be any _useful_ activity on the Z80 pins. The chip is
basically melted. Most of the chips are like that. There's paper clips
permanantly fused to other parts of the board.

But then, how many PCs are there of which this can be said? I can think
of:
*IBM PC - tony said it, not I
*Altair - I think the general consenus is that it was a cheap design
*IMSAI - The PSU and cooling design
*Apple /// - I guess the main problem w/these was the high-density board
*Mac Plus - The PSU and probably other stuff too
*VICs and C-* - I've heard almost everything about these
Of course, I would have included many modern computers, but one can hardly
give someone the techrefs for those :)

Any dangerous parts, like in the Mac Plus?
