Cigerette stink is worst I know but this one I'm bit lucky doesn't
stink like one EXCEPT that Mac II has collected so much regular dust
in it's life then pushed to storage is bad location where there's
humidty is high for long time. That's before I rescued that Mac II
from goodwill for $5.
Now it stank of must and dust. What is your process to destink that
Mac II? Scubbing is part solution but this case is full of
cravities and crannies, lot of hidden carvities under that tin sheet
fastened in place by melted mushroomed plastic pins. Best way I
think is soak it in some kind of chemical. including that PSU minus
fan.
The worst of that stink is in PSU and whole case. I'll have to take
apart that PSU but the case is another matter.
Hey, it's 1987 machine so classiccomp applies! :-)
What's the solutions to attack this? Bleach dip, ionized chamber
(for smoke damage repair) etc? Comments please and where to
find some de-stink services locally?

In my experience musty smells like something is growing in something else
can be dealt with with rite guard. No kidding, it's mostly alcohol. Mind you
I haven't tried this with electronics, this was how I dealt with the heater
in my VW smelling like mildew after the car got filled with water in a flood.
But a deoderant like riteguard is, after all, an anti-bacterial with a fragrence.
Mind that you don't get the antipersperant kind - aluminum salts aren't going
to help anything and I suspect they'll conduct...

Alcohol do very little to dislodge junk and only kills bugs and
mildew but the remains stays there and still smell.
Even the windex help very little it's consumer grade. Very weak.
What I'm looking for is real thing that oxidizes the stink and get
all the dirt and junk floating out of hidden cravities with a flush.
10 years ago I used freon spray once on several cards out of a one
computer before putting that computer into friend's home was spray it
down with freon stuff. Amazing stuff, icky stuff simply slides off
leaving shiny boards like new, too bad it's not good to hole and it's
banned.
That one would do *perfectly* like mine.

I wonder if you could use ozone to oxidize the crud in it? Perhaps
you can set the open case on top of a laser printer or something else that
generates ozone. Ozone oxidizes the same way that chlorine does but it
doesn't bleach things out or smell the way that chlorine does. As for
cleaning the debris out, I would take the case to one of the high powered
spray car washes. It may take a while to dry all the water out of all the
cracks and crevices afterwards! A vaccuum oven is great for drying things
like that.

Compressed air for the bulk of the unit, soap and water on most of the
case, and the stinker is typically the power supply which needs to be torn
down and chemically cleaned.

I picked up a machine from a restaurant that instead of
having the dust bunnies inside had greasy blobs. It stunk
so bad I had to move it to the garage until I had the time
to strip it down and give it a washing in soap and water.
I've also had a machine that had clumping cat litter spilled
into it. The shop vac took care of that problem.

I use partial disassembly, vacuuming, and spot wash.
The partial disassembly is 99% just take the cover off
and wash it.
The worst smelling stuff is usually just the dust (in
extreme cases mouse nesting) which is easily removed
with the vacuum. (If it really is nesting then don't
breathe it and Wash your hands frequently.
P.S.This has never been in computer equipment)
I might do spot dusting with a Q-tip wetted with Window
cleaner, mostly just to lift the dust.
Don't be too afraid to take it apart, you get to learn
how its constructed, that's a fun part.
Also don't give up on the spray dusters. Here in the U.S.
they've just mutated to a less Freonic form.

In addition you pretty much have to experiment in areas not visible with
different things. If I had a fire in my shop the whole block would likely go
up with the varying array of chemicals and solvents I have. When I have a
unit that will be stored and needs to stay dry, bug free and mold free I
take 6 or 8 moth balls (paradichlorobenzine) in a cotton cloth and set that
inside the unit. Mice don't like it, bugs don't like it, it keeps it dry
like camphor does with tool storage, and it makes the unit smell a great
deal better. Of course it's not a quick or permanent cure to smells from
previous mold/tobacco contamination but it works to prevent things from
extended storage.

I've had good luck using Pursue to kill odors. Pursue is sold by
Amway and it comes in a spray can. In general, it works better than
anything else that I've tried. I haven't tried it on a computer so be
carefull. It may attack plastic. You may want to put some on a rag or
something and then close it and the puter up in a large box for a day or
two to give it time to penetrate. A small fan in the box would probably
help. Let us know how it works.

The bad thing with Amway is once you're on their customer list you're
destined for life to be bugged by them. The few Amway products I've
purchased were added to someone else's purchase and I repaid them when
delivered, keeping my name totally off the list. Many of their products work
well but you pay a premium for them.

Plain rubbing alcohol is excellent for removal of the gung of both mildewed
or tar/nicotined equipment and it's cheap. Walmart and other chains carry
quart bottles, I buy them at a local pharmacy by the case at a 5% markoff).
Use it liberally but with the unit powered down, since you still have to be
concerned with shock/short since there's 30% water in it. Don't buy the
useless alcohol that's less than 70%, it doesn't work well at all. It also
freshens the smell of machines once the tar/nicotine or mildew/mold is gone.
If you have vents, circuit boards, etc you can get a good horsehair or parts
cleaning brush soaked with it and scrub them (try first on an area to insure
it won't hurt anything) and that removes stuck gunk off the components.
If you're cleaning a cdrom that was used in a smoking area, use lens tissue
(photo grade) to final polish the laser so that it has all of the stuff off
and the alcohol doesn't leave a streak/haze on the lens. I continually clean
cd players for people's stereos as a side job and they are an easy fix. This
is a heavy tobacco use area (Ky, why of course) and also very moist/prone to
mold/mildew. I get both mildewed/musty items and tar/nicotined items all of
the time - and the contaminent is usually the cause for the item's failure.
Denatured alcohol can be used many times too but be careful of how it reacts
as it's not water based and can remove stickers, decals, etc. I also use
green Scotch scrub pads many times with isopropyl to scrub the units or use
a vegetable/nail brush with iso to scrub the outer cabinets that have the
mottled finish. They generally come out looking near new, if not like new.
409 also works well on outer cabinets but isn't much on certain stains such
as tar/nic or toner stains. Citrus cleaners are good too but act like a
solvent on many articles, dependant on the cleaner and the item. Some citrus
cleaners are made from the oils in citrus peels rather than from the citrus
juice and the oils are in the same category as toluene or lacquer thinner on
many plastics (isn't lacquer thinner made from a fruit product?)

My A4000 came out of the household of an aging smoker, who was losing his
tests of grey hair. Not only did the machine smell (a lot!), it was also
coated with tar and other airbourne substances, into which his hair had stuck.
Then there was the coffee and dead flies in the keyboard.
In any case, I and a mate stripped the machine down as thoroughly as possible,
then proceeded to use a brush to wipe the dust off the PCBs and remove the
sticky film with some kind of clinical alcohol and tops (the kind you put in
your ear). The case was put in the shower, can't remember whether we used
anything to rub it, but I suppose that steel wool would be fine in the case of
metal parts.
Ah yes, we washed and scrubbed the case like you would with any dirty plate in
the kitchen sink.
If it stinks after this treatment, I'd have no idea what to do next.

In that case with A4000 case it's simple smooth case with few

with this task. I once cleaned plastic grills for a household fan
(that type that used round rotating vanes to direct air around via
small motor.) Very tedious and hard, imagine that brushing hard with
old toothbrush on small square of hole getting all grime and dust
out. Mac II case is like that most of cavities are hidden.
To few who have stinky cigarette-coated and others that is
spoiled with grease films (as from kitchen enviroments) machines,
mechanical cleaning and harsh chemicals and active chemicals is only
way to break down those dried tough rancid oils (hardened like
linseed oil on wood).
Once I tried the major cleaning on a minitower peecee case (just
that it, threw out working PSU. (!!) ) of cigarette smoke stain.
Plastic sucks up stain+stink while painted surfaces does to
small degree. Even well scrubbed and very C-A-R-E-FULLY few times
with many cleaners and alcohol, lots of paper towels. I can't get
smell totally out. Actually still emits stink strongly even surfaces
is spotlessly clean and towels came up clean after last few
days of off and on attempts. Gave up and traded it away for small
"cash" towards other stuff.
The multi-year of kitchen grease coating is TOUGH! Nothing we can
find will touch it, boiling it in water and some soap got it softened
enough to scrape'n scrub off with some work. That yuck was on
kitchen plastic fan to get noise and viberation down in a college apt
kitchen fan once, clean fan ran much better and quieter on oiled
motor. :-)
Mildew and fungus growth matter are stuck to the all surfaces and has
to be removed by oxidizing action, scrubbing merely remove some of
them.

What about this idea:
Taking all the parts that can be "dipped" and making them sit in very hot
water in a large plastic garbage can with some kinda "citrous based"
cleaning product mixed in?
Will the hot water not "open up" the plastic "pores" a bit and let in
leech
a bit of the smelly stuff out.
I used to be able to dye plastic parts (teflon and similar) easy with
boiling water and Tintex clothing crystal dies. I think the hot water really
"opens up" the plastic and can really get into the top layers...
And this idea : how bout trying to bring back a yellowed (UV light) computer
case by dying it with white TINTEX crystals in hot boiling water...???
Ill have to try that one...
Up here, nooks and crannies get the treatement from a brush with long
brissles..."flings the crap out"...

The last 3 weeks have been a bit busy. We recieved a very nice B series
IBM AS/400, plus docs. A System 36 PC is also promised later.
We picked up an abandoned Wang VS-85 system in Wells River, Vt. BNo
power in building so everything had to be broken down with a trouble
light on a long extension cord. 3 CDC 9766 drives, one for parts I
think, plus the cpu, an 8 inch archiver and some unknown bits. A nice
find was an Apollo MSD cabinet cabled into the system. We also found a
new type of Wang terminal, the 2866, which we had not seen before.
We visited Syosset, NY to pick up a Datamaster that Rich Cini gave us,
and this morning receieved a frantic e-mail about some DEC equipment in
Danvers. The owning company was transferring some of its operations to
Texas, and we were given what amounted to a small DEC computer room -
platters, tapes, platter cabinets, a CDC 9762 drive, a micro-Vax, a
PDP-11/53, and a 3-cabinet PDP11/83, plus a large number of orange and
grey manuals.

Jerome Fine replies:
I have access to a PDP-11/83 in a BA123 cabinet. Although the ESDI hard
drives run outside the box due to cooling problems, unless I added a cabinet
for some RL02 drives just for compatibility, what could an 11/83 consist of
that would need 3 cabinets? Also, which OS were the PDP-11 systems
running? And anything available to be shared or sold?
I guess that if the 11/83 was very old, a few tape drives and RA81s could
occupy even more than 3 cabinets. I guess I am thinking in terms of hardware
which is just 10 years old. Those ESDI hard drives are 600 MBytes each
and are only the 5 1/4" full height drives on a Sigma RQD11-EC controller.
Even Seagate put out the ST8760E more than 10 years ago.
Of course, the actual real hardware 11/83 rarely gets any use now that
the a Pentium III can run all that code at ten times the speed of the 11/83.
What will happen when we switch to a Pentium IV running at 1.7 GHz.?
Note that I am not saying the Pentium IV is better - only that it ends up
running the programs written for the real PDP-11 hardware so much
faster that it is no longer efficient to develop and test code on the 11/83
except for a final checkout just to say it has been tested on the actual
real PDP-11 system.

I'll try to remember. There was one RX02 drive. There was a TK50 tape
drive. There may have been a DSP800 drive. Most of the rest of the
space was RL02's. There were at least 3.
We probably have some spare RL02 platters and some TK50 tape cassettes.
System ran RSX-11M.

We visited Syosset, NY to pick up a Datamaster
that Rich Cini gave us,
and this morning receieved a frantic e-mail about some DEC equipment in
Danvers. The owning company was transferring some of its operations to
Texas, and we were given what amounted to a small DEC computer room -
platters, tapes, platter cabinets, a CDC 9762 drive, a micro-Vax, a
PDP-11/53, and a 3-cabinet PDP11/83, plus a large number of orange and
grey manuals.
Jerome Fine replies:
I have access to a PDP-11/83 in a BA123 cabinet. Although the ESDI hard
drives run outside the box due to cooling problems, unless I added a cabinet
for some RL02 drives just for compatibility, what could an 11/83 consist of
that would need 3 cabinets? Also, which OS were the PDP-11 systems
running? And anything available to be shared or sold?
I guess that if the 11/83 was very old, a few tape drives and RA81s could
occupy even more than 3 cabinets. I guess I am thinking in terms of hardware
which is just 10 years old. Those ESDI hard drives are 600 MBytes each
and are only the 5 1/4" full height drives on a Sigma RQD11-EC controller.
Even Seagate put out the ST8760E more than 10 years ago.
Of course, the actual real hardware 11/83 rarely gets any use now that
the a Pentium III can run all that code at ten times the speed of the 11/83.
What will happen when we switch to a Pentium IV running at 1.7 GHz.?
Note that I am not saying the Pentium IV is better - only that it ends up
running the programs written for the real PDP-11 hardware so much
faster that it is no longer efficient to develop and test code on the 11/83
except for a final checkout just to say it has been tested on the actual
real PDP-11 system.
Sincerely yours,

New subject: destinking the computers.
The case was put in the shower...
OK, I did this once too. I once had the extreme pleasure of finding a
uVax3100+VS3100 left out on the curb with the trash. Turned out they
were both filled with fine silt. I figured that it could've been 1 of two
possibilities: We had a bad hurricane 2 years ago that probably flooded
the guy's basement (or, his frustruated wife could've frisbee'd the things
into a lake <g>). Anyway Dr. John was too late. Some fragile parts had
corroded through and there was residual water in the HDD's.
But I tried anyway. </Ramble off>.

New subject: Diablo 3200
I've been told that a local computer scrap warehouse has run across
something called a Diablo 3200 apparantly built into a custom Desk. I'm
afraid the guts will be removed as trash so the unit is probably history
but it got me to wondering what this machine was all about. I had worked
for Diablo during the Daisy wheel days and had heard references to other
equipment made by Diablo prior to being bought by Xerox but didn't know
specifics.
I'm told that the equipment consisted of a CPU and at least 1 8 inch disk
drive.
Anyone have an idea what OS might have used. Was it CP/M or something
less universal?
Best regards,
George Rachor

I just picked one up within the last month. I don't have a picture of it
but I can get one today.
It's an 8080-based machine that was marketed as an office data processing
system. I company I pulled it out of used it to do payroll and stuff up
until a few years ago. The machine was sold in the late 1970s. I think
it first went on the market in 1977.
The computer part is stuffed underneath the desk on the right-hand side.
The disk drives (mine has four 8" floppies) are on the left. The terminal
is built into the desktop. It also came with a separate daisy-wheel
printer.
It reminds me very much of the IBM 3741 Display Station that I picked up
about a month prior to this. In fact, I'm speculating that the 3200 was
Diablo's attempt to better the 3741 and compete against IBM in the small-
to medium-sized business realm. The 3741 has a small terminal built into
the desktop (very small, only like 4" across) and two 8" floppies mounted
vertically on the surface of the desk. It also came with a separate dot
matrix printer. The 3741 was sold as a data entry terminal, but it
actually had a BASIC interpreter and most likely other languages could be
gotten for it (mine came with BASIC).

The Diablo 3200 ran CP/M.
It would be a shame to let this beast go to its death. I've never seen a
Diablo 3200 before or after the one I got, in fact I'd never even heard of
it, and I'm a bit surprised to see mention of another. My guess is that
they are extremely rare. You should do what you can to rescue it,
although it is a bit sizeable and would take up a little space in your
garage or what not.
Diablo was a San Francisco Bay Area company that was more than likely
named after Mount Diablo, a rather large mountain east of the hills
separating the Oakland east bay area from the inland east bay area
(locally known as the Tri-Valley area :) Up until I found the 3200, I
didn't know they made anything other than disk drives and printers.

Sellam,
Stay of execution on this Diablo 3200.....
We have bought a bit of time as my wife has convinced them not to hack it
up until I get to see this critter.
Obviously we have no software for the machine and I'm assuming you don't
either.
The computer recycler has agreed not to remove the original components
until it can be determined if the box is usuable in some rudimentry
function as is. (They were going to gut the original components and
replace the guts with something more modern).
Now the challenge is to find software that might boot the machine up.
slightly hopeful...

Physically, it's a large desktop case with a 12" mono CRT on the left
side of the front panel and 2 vertically mounted 8" drives on the right.
The separate keyboard is wired into the unit with a cable that can't be
unplugged at either end without dismantling the machine somewhat. On the
back of the main unit is a DB25 connector that I assumed was an RS232
port for a daisywheel printer (probably a Diablo 630 or similar).
It would seem to be later than the 3200 since it uses an 8085. But no,
never heard of it. Interesting though!

From what I remmeber of the insides, the drives
and monitor are what
you'd expect. There's a little cardcage behind the
monitor that contains
4 (IIRC) boards. One of them has an 8085 CPU on it, another was RAM, and
another was a disk controller (I think there was an 8039 microcontroller
on this one -- I don't remember a standard FDC chip). The power supply
was in the base of the machine under all that lot. I don't really
remember any more details.
