I had a business meal tonight and after some discussion I found out that
one of our guests is sort of into collecting old computers (basically he
never got rid of any of the systems he's bought over time). One of the
systems he mentioned he had was a Video Brain. Apparently this is a
video game system. I *think* I vaguely remember hearing about this
system. At any rate I'm curious about it and was wondering if anybody
knew what it was as we both had too much tequila for him to describe and
for me to comprehend it.
I told him of my plans for the First Annual Vintage Computer Festival
(which, by the way, is still on...I'm still in the planning phases) and
he mentioned that he had close contacts with a show called The Computer
Guys on the Discovery Channel and would arrange for me to meet with them
to discuss possible coverage of the show. Very nice!

At one time I had a PDP8/e and a PDP11/44 _on my desk_. They were thus desktop
computers :-). The 11/44 is now elsewhere, since I now have the 8/e's
peripherals on my desk....
Hi all,
I just acquired a Lisa 2/10 and I'm trying to figure things out.
The system starts to boot from the hard drive and comes up with a
MacWorks/Sun Remarketing logo, then asks for a diskette. Looks like
it's running MacWorks XL, is that correct? The system still has regular
Lisa H/88 ROMs so it's not messed with hardware-wise.
How come it wants a diskette and won't boot from the HD? I tried
putting in a System 1 diskette from my Mac 128 and it gave me the
"Welcome to Macintosh" splash and then died with a Sad Mac FE0002.
Do I need a special Mac System version diskette to boot this sucker?
Any info appreciated!!
(anyone have a spare keyboard? I need a few keys)
thanks
Kai
Does anyone know if one can still get Flex for the 6809 or 6800?
There're people archiving and using CP/M stuff but it seems a waste to
let a very simple and neat OS like Flex go the way of the dinosaur.

I am still sorting through my stuff and have a few odd items up on the
eBay auction. These type of things go pretty cheap (a buck for 3 power
supplies and 4 RF adapters? Cheaper than the Goodwill!) but are
sometimes hard to find (especially when you need one...power supplies?).
Anyway, all you have to do is go to the link listed and check the price.
Remember to figure shipping into what you want to pay. I'm in CA.

Are old (classic) computer magazines worth more now than the issues price?
Example: original first issue of BYTE magazine? Or can I tell my husband
to throw them out and give away the tin shed?

Sounds like the software is not seralized properly and it wants to see the
diskette to validate the software. (the Lisa serialized the software to
the machine on initial load)

=============================================================================
1.1 I just picked up a new machine. What should I do?
Don't power it up yet! All of the following should probably be done
before that power switch gets flipped.
Open the case - clean and visually inspect components. You're
looking for traces of smoke, water, corrosion, loose screws, blown
caps and resistors, cold (broken) solder joints, bent pins, etc. It
may be a good idea to remove and re-seat all socketed components and
connectors. If anything burned or overheated it will probably pay to
replace it before powering up the unit. You can avoid a number of
problems just by taking a peek inside.
If you have the tools (and the machine is sufficiently rare) pull and
dump backups of all EPROMs, ROMs, and PALs. If you have really cool
tools (like a logic analyzer) it has been suggested that you use them
to record critical information from those oh-so-hard-to-find custom
chips. Specific information on how to do this is beyond the scope of
a FAQ, but you probably know what you need to if you own the appropriate
tools.
Disconnect the power supply from the rest of the computer and start it
up on a "dummy load". A six volt headlight bulb has been recommended as
a convenient load. These should be available from any decent Volkswagen
shop. Running the power supply without a load could result in damage to
it. You may want to check the voltage output before you do this as it
could be no where near the 5V average in micros. Even if you don't want
to connect a load it's still probably a good idea to power it up
separately from the computer for the first time. If you have a really
rare beast it may be worth powering up some of the key capacitors out of
circuit just to get them warmed up.
Now you can power it up. Assuming it works, take a blank disk,
format it, write some data to it, and read it back before using your
precious software with it, as a bad disk drive could really ruin your
day.
1.2 What's the best way to clean these dingy tan boxes?
Cases: It seems best to start gently with such old equipment. Try
soaking in a little water and dish soap and then scrubbing. This takes
care of most jobs. For removing stickers try mineral oil or Goo-Gone
(available at most hardware stores - in the US at least). If those
don't work, acetone can be good but, if overused, can do more harm.
For removing marker, almost any solvent is good (alcohol, naptha, etc)
but will definitely discolor or dissolve plastic if not carefully
applied. Lava soap is also good for removing marker but can smooth off
textured plastic. For removing sun or tobacco discoloring a product
called Purple Stuff available from auto parts stores (again, in the US
at least) seems to do the job almost effortlessly.
Recommended commercial products:
Purple Stuff from Kragen [for discoloration]
Brasso [ink/marker] (can discolor plastic)
Antistatic Foam Cleaner from Electrolube [for discoloration/markings]
Citra-Solv [for discoloration] (can dissolve plastic if undiluted)
Cameo Copper Cleaner [ink/marker]
Naptha [for stickers/goop/spooge] (very flammable)
3M GP Adhesive Remover [for stickers/goop/spooge]
CRC 226 / CRC 556 [for stickers/goop/spooge]
Fulcron [for discoloration]
Blue Shower / BS II [for stickers/goop/spooge]
Connectors: For edge connectors a plain pink eraser seems good
for removing corrosion. Apparently other colors of eraser indicate a
different texture - which may be damaging. Make sure to wipe the
connectors with a clean cloth after erasing on them. There are a large
number chemicals on the market that "magically" remove corrosion from
components but as I don't know how safe they are, I'm not anxious to
promote any of them. For pin style connectors a toothbrush and some
softscrub or other mildly abrasive cleaner do wonders.
Recommended commercial products: Electrolube contact cleaning sprays.
Keyboards: I find a cycle through the dishwasher does a really nice
job on keyboards. Just be sure they're completely dry before you
put any power to them. If there is reason not to use a dishwasher
(some key labels can come off) it is usually possible to remove each
keycap and clean conventionally.
[][][][][][][][][][]
2.1 What's a hard sectored disk? What's a soft sectored disk?
We'll start with soft-sector since they're simpler to explain. On a
soft-sector floppy disk the information that marks where a sector
begins and ends is written to the disk by the computer (part of the
formatting process). This means that various computers can use
the same floppy disk types because the format of the disk is control-
led by the operating system.
Hard sector disks use a system of perforations in the media to mark
the beginnings and ends of sectors. This means that computers
which used hard sectored disks required the exact disk type they
specified rather than a generic soft-sector floppy. A number of
differently sectored disks were available - at least 10, 13, and 16
sector formats. 8 inch and 5.25 inch disks commonly used hard
sectoring. 3.5 inch disks never came hard-sectored and, in fact,
it would not be possible.
2.2 What's SS/SD, DS/DD, DS/QD, DS/HD, etc.
These all refer to the number of useable sides on a disk and it's
density (how "efficiently" the magnetic bits are pushed together).
SS/SD is a Single Sided - Single Density disk, the earliest available
type I believe. The storage afforded by a single density disk was
very small compared to today's standards. Single Sided disks were
popular because they were cheaper than DS and could be easily
modified with a hole punch into double sided disks. SD was followed
by Double Density which, amazingly, doubled the amount of storage
space. Double Density was followed by the extremely short-lived
Quad Density which doubled a DD disk. QD was short lived because
High Density was right on it's heels and nearly doubled disk capacity
again. DS/HD was as sophisticated as 5.25" disks became. 3.5"
disks have progressed as far as DS/EHD double-sided / extra-high
density.
2.3 Can these formats be interchanged?
Well, that may depend on what computer you are using, but in general
the following substitutions may be made:
Desired Format Substitute
---------------------------------------------------
Single Density Double Density
Double Density none reliably
Quad Density DD, HD (sometimes work, not advisable!)
High Density none
Other substitutions may be made, but due to physical differences in
how the disks are made they are generally unreliable. It can almost
be guaranteed that data written to a proper density disk of poor quality
will last longer than data written to a good quality disk of the wrong
density. In the case of quad density no substitution should be
considered reliable. DD and HD disks both can be forced to work. One
may work better than the other given the peculiarities of various drives.
2.4 What disk sizes are there? Disk Types?
Physically?
Standard Disks Unique/Proprietary Disks
---------------------------------------------------------
8" (Floppy) 5" (MiniFloppy)
5.25" (MiniFloppy) 3.25" (MicroFloppy)
3.5" (MicroFloppy) 3" (MicroFloppy)
2.5"
2"
In addition to odd sizes - there is at least one type of disk which
was physically different. "Twiggy" disks for the Apple Lisa 1 were
regular 5.25" disks with the exception that they had two read/write
windows. One was oriented "north" of the center hole, the other "south".
2.5 How do I take care of old media?
Step one is Back It Up! After that, make sure it's kept in a clean, dry,
temperature-controlled environment (I keep mine in a broken freezer).
With disks it seems important to keep them standing on end rather than
lying flat - the same goes for cassette tapes. I like to exercise disks
and tapes at least once every six months although I have no real
evidence that this has any positive effect. I have modified an old C64
floppy drive to simply spin when a disk is inserted and send large
stacks of disks through it on a regular basis just to make sure they're
not starting to stick up internally.
An exciting and somewhat recent development is that availability of
classic computer emulators that can make disk images of old media
on PC's and Macs. This seems to be a very good way to backup
disks since they will eventually go bad no matter how well we take
care of them.
The official line seems to be that floppy disks have a shelf-life of
approximately 10 years. With proper care many are lasting a lot longer.
[][][][][][][][][][]
3.1 Do EPROM's go bad?
Definitely. They apparently are considered to reliably contain data for
(on the outside edge) 15 years. This amount can be considerably
reduced if, for example, the sticker over the window has dried out and
fallen off. Luckily EPROMs were not used too extensively but they're
out there. An EPROM writer/reader is a relatively cheap investment
and an easy fix. Even if an EPROM has "forgotten" it's data it is still
fine for being "re-educated".
3.2 How about ROMs and other chips?
Things wear out. It's likely that even components which have not been
fried by catastrophic failure will simply start to die someday. ROMs can
be dumped to a file and re-written if they die. Other custom chips which
are all too common in micros will be far more difficult to replace. The
best advice is to stockpile these chips when you can - but someday even
unused chips will probably start to turn up bad. In this case the best
defense is to stockpile information in the hope of being able to modify
an existing component to meet your needs.
3.3 How about capacitors?
This seems to be another large concern, but rather than being an
unreplaceable component a capacitor will take your unreplaceable
components with it when it goes. It's a good idea to check out all the
caps in a system if you haven't fired it up in a while. Caps go bad
with time (even tantalum caps, apparently - although they are more
reliable) and should be replaced if they are suspect. It's unlikely that
it will be impossible to find a replacement capacitor as they are much
more standard electronic components.
3.4 Anything else?
Documentation: If there's anything which is entirely unreplaceable its
the docs for uncommon equipment. Once they're gone, they're gone.
I regularly pick up docs I find for equipment I don't have just because
I may someday. Paper will, of course. go bad over time but it will be
obvious and they will be easily duplicated.
Hard Disks: ST-251s, ST-502s, MFM, RLL... old hard disks are going
to go bad. Then they'll be gone. Theoretically, I suppose it's possible
to crack a hard drive and replace a dead bearing, realign, relaminate,
etc... but I've never heard of anyone doing these things in their base-
ment. Perhaps in another 5 or 10 years many of us will be experts at this.
3.5 So, how do I back up all this stuff like you suggest?
This answer will undoubtedly get longer as I learn more. The best ways
seem to be to dump the particular ROM (or whatever) using the approp-
riate equipment to a floppy disk (which most of this equipment allows).

=============================================================================
1.1 What is ClassicCmp?
It's a mailing list for the discussion of classic computers. Topics center
on collection, restoration, and operation. It is also an appropriate place
for stories and reminiscences of classic computers. Lofty discussions
dealing with the philosophical and/or metaphysical aspects of computers are
often better handled in private e-mail.
1.2 Why is ClassicCmp?
Uh, why not? There are lots of people who love these old machines and it
seems like a fun idea to get together and talk about them.
1.3 What is a Classic Computer?
_Any computer_ that has not been manufactured for 10 years is a classic.
This definition is one I made up and it's entirely arbitrary. It seems to
work OK, so I've kept it.
1.4 Who runs this thing?
That would be me, Bill Whitson - email bcw(a)u.washington.edu.
1.5 How come I can never reach this so-called list operator?
Sorry. It does often take me several days (sometimes weeks!) to respond
to e-mail. I am often away for days at a time and when I'm not I'm still
probably busy doing real work. I receive more than double the amount of
mail that goes to the list in the form of spam, bounced messages, odd
user requests, general bitching, etc. and I still have to filter out the
messages I actually have to respond to, to remain employed ;). I will get
back to you eventually.
1.6 Do you know you're just duplicating work other people have done.
I get a "reinventing the wheel" e-mail at least once a week. If you show
me another group of computer collectors that claims a membership as large
as this one I'll show you a group that must be very hard to find. Obviously
there are other groups of collectors and I'm cheering them on - I don't see
a problem with duplicating and reduplicating lore that's quickly disappearing
anyway.
1.7 How much mail should I expect to get on this list?
The daily load varies widely from about 10 messages to over 100. Average
seems to be about 44 messages a day. There are times where the message
load peaks for as much as a week.
[][][][][][][][][]
2.1 What can I talk about?
Anything related to classic computers as defined above. There are many
people on this list that really know what they're talking about, so you might
want to check facts before you start shooting off messages. It's also a
good idea to actually read the FAQs and check the archives a little before
posting.
2.2 Can I talk about PCs?
Yes. PCs which haven't been manufactured for 10 years. Even then, be
aware that in many cases you would get a better response posting to PC
newsgroups.
2.3 Can I talk about Minis/MainFrames/WorkStations/Gigantic Talking Boxes
with Flashing Lights & Coundown Timers/Robots from Alien Civilizations?
There has apparently been some misconception that this is a list for
micros/home computers only. You'll note I said "misconception".
2.4 Can I post advertisements?
Sure. As long as they're related to _classic_ computers. And, of course,
use your brain - don't spam. Also, please state up-front whether or not
you are willing to ship the items you sell outside your country as there
are members of this list in a number of different countries.
2.5 Can I ask people to sell/give me their computers?
Sure. But you're not likely to get a very nice response. Mine, for example,
would be: Get your own f***ing computer! There are several people on
usenet who will vouch for this. When someone posts about one of their
machines without offering to sell it - it's really a pretty good bet that
they're not secretly trolling for offers. See section 5 for info on how to
find yourself a computer.
2.6 Can I ask for help fixing item x.
Yes. Be aware that it may be difficult to help you fix things if you don't
have much knowledge of how computers work or of how to use basic
electronics tools (VOM/DMM, soldering iron, EPROM burner, etc). I'm no whiz
with this stuff and the little knowledge I have has come from asking
questions and then buying books to find out what "Simple... Just check
the voltage on the caps in the PS to make sure one of them isn't flaking
out!" exactly means.
2.7 Where can I look before posting a dumb question?
It might be a good idea to take a look at what's available in the Archive
section of the ClassicCmp web site (see below).
2.8 Can I type obscenities about Microsoft in ALL CAPS!?!
(Or, in general, be unreasonable with reagard to advocacy posts?)
Check your anti-MS baggage at the door, please. For that matter, drop
any posts that serve only to perpetuate the holy wars.
2.9 Can I post trophy lists?
Ahem. Er... I'm not going to go to the extent of banning this practise
but it is considered bad manners. Don't whine to me because I used to be
guilty of this and curbed myself ;). Post lists of newly acquired goods
if you actually need info on them, not just to show off.
2.10 Can I use obscene language in my posts?
Yes. Although I'm sure many people would prefer you did not. A number of
people have complained about this. I'm not going to outlaw swearing - now
that I've informed you that it bothers people you can make your choice.
[][][][][][][][][][]
3.1 How many subscribers are there?
Around 180 and changing daily.
3.2 How many subscribers use machine x?
Check the web site (see below). The Classic Computer Encyclopedia shows
the number of machines registered by subscribers.
3.3 Is this list archived?
Yes. The archives are available on the FTP site (see below) in the
directory /pub/classiccmp/archive. The file name format indicates
the month/year of the archive. Keep in mind that they are quite large.
[][][][][][][][][][]
4.1 Does ClassicCmp have a web site?
Yep. http://weber.u.washington.edu/bcw/ccl.html
4.2 How come the web site is so ugly?
How come a PET is so ugly? Who cares as long as it works?
4.3 Does ClassicCmp have an FTP site?
Yes. Anonymous FTP at 140.142.225.27. Look in /pub/classiccmp. There's
not much there that's not available on the web site. I'm starting to
load old drivers and system disks on occasion. There is an incoming
directory which subscribers may use for ClassicCmp-related file transfers
if needed.
[][][][][][][][][][]
5.1 Where can I find classic computers?
The best places seem to be thrift stores and swap meets. These are
closely followed by pawn shops and mom and pop computer stores.
The holy grails are electronics scrap yards - but they tend to be wary
of individual pick-and-choosers. Oh yeah - garage sales!
5.2 How much is machine x worth?
Precisely as much as you'll pay for it. Oh, you're selling it? Then,
precisely as much as I'll pay for it. Seriously, no one prices these any
more. I have an old Computer Blue Book that lists many classic
computers but the prices are just ridiculous. Some machines (Apple
Lisa's, old old Mini's, and unreleased prototypes) are starting down
the road toward their original selling prices but it's unlikely that
most will ever be worth more than the cost of their components.
5.3 Will 1000's of innocent machines be scrapped if I don't save them?
Yes. This is the impetus behind every collector's tireless and selfless
effort. Each machine we fail to save has it's gold parts mercilessly
hacked off and sold (just like rhino horns - and look at the rhinos).
The remainder is then sent to China to be made into bicycle spokes (you
probably think I'm joking). Save a computer! Act now! Remind your
SO of the rhino and cuter, fuzzier animals. It might work.
In all seriousness - there are a large (and growing) number of so called
"computer and electronics 'recyclers'" who take usable computers and
recycle them into "reusable scrap". Small amounts of gold, silver, and
platinum are extracted and the remainder of the material is generally
just marketed to less wasteful countries.
5.4 I don't understand anything. Help!
Don't worry - you're not the only one. Reading this list, old magazines,
books and whatever else you can get your hands on is the first step.
