It could have been.  I think EACA were looking at something people could
just pick up, take home and use without extra cables and "other bits".
This is why as well as a built-in tape deck there was also and RF
modulator, so it could be plugged straight into a (or "the) home TV.

Oh yes, the styling is clearly very similar. I like the built-in tape drive. Do

I bought the lovely SOL-20 system yesterday. Picture:

https://twitter.com/nf6x/status/790631315695513600

It will probably be a week or three before I work with it in detail, because 
right now I'm nominally working on my absurd Retrochallenge 2016/10 project of 
making a USB interface for an RL02 drive.

Now I'm on the lookout for a small, monochrome, composite monitor of late 1970s 
vintage to set on top of it. I have other monitors which will be functionally 
just fine, but which won't look Just Right sitting on top of the SOL-20. I'll 
probably do initial work with my little Apple IIc monitor, just because it's 
small and easy to carry.

This system came with an 80x25 video card, but I plan to initially use it in 
its original 64x16 glory. I'll either upgrade to 80x25 later in the natural 
progression of getting to know the new system, or use it in the other S-100 
chassis that I am building up.

I don't know about the system's operational status yet. I'm going in to the 
project assuming that the capacitive keyboard is dead, the electrolytic caps 
are dried up, the drive heads are filthy, and the bearings are gummed up. Maybe 
the condition is a lot better than that, but those seem like reasonable 
assumptions for a computer of its age that hasn't been used recently.

Viruses.

The Latin word _virus_ means "slime, poison", and is a collective noun, like
English _milk_ or _flour_ or _sugar_.  It did not form a plural at all.

Furthermore, it is a neuter (neither masculine nor feminine) o-stem noun, very
very odd because it ends in -us rather than -um in the nominative.  -us is
overwhelming the marker of a masculine o-stem, or occasionally of a masculine
or feminine u-stem (whose plural would be in -us), and very rarely of a
feminine o-stem, or often of a neuter s-stem (like _genus_ "kind", whose plural
is _genera_ "kinds").

The -i marker of nominative plurals is restricted to those masculine and
feminine o-stems; -ii is restricted further, to o-stems in which the stem vowel
is preceded by -i-, so _domus, domi_ "house, houses" vs. _genius, genii_
"tutelary spirit(s) attendant on a person from birth", _Julius, Julii_ "a
_gens_ (clan) name, members of the Julian _gens_", _Cornelius, Cornelii_, etc.

Neuters in all ancient Indo-European languages, such as Sanskrit, Greek, and
Latin, end in -a (or a regular development from *-a).  Presumably, if one were
able to specify a plural in Latin of the word _virus_, it would by rule have to
end in -a.  But the speakers of Latin did not speak of discrete slimes, it all
being one to them, so we will never know.

The word _virus_ was used as a synonym for _venom_ as late as the early 20th
Century in English, as in Burroughs's description of the deadliness of the
_virus_ of Martian serpents (in _The Gods of Mars_), which confused me no end
when I was reading the Martian novels for the first time at the age of 14.  The
modern usage derives from the medical term _filterable virus_, referring to a
disease-causing agent which was unresolvable under a microscope but which could
be mechanically filtered out of water, unlike a poisonous chemical dissolved in
water.  The word _filterable_ was dropped at some point in the literature, then
electron microscopes came along which *could* resolve viruses, and we come into
the modern world.

More than you ever wanted to know, I'm sure.

  MS-DOS had CP/M at its heart, and it had its fair share of virii (viruses? 
What is the plural of a computer virus?).  The discussion Liam linked to
(https://groups.google.com/forum/#!topic/comp.os.cpm/V1-zYzA6Uzg) seems to
echo my own thoughts here---technically, it's possible, but not probable due
to the resource constraints (mainly memory) inherent in CP/M.  There is
nothing that also requires a virus to run a background process---it can
certainly modify the existing program to infect other programs, but again,
on CP/M because of the contrained resources (and lack of speed) such actions
might be noticed by the user.

  And in my experience [1] most viruses would infect executable programs and
it wasn't until Windows, when Microsoft went out of its way to find any form
of code in any file type and execute it, did viruses start infecting other
types of files (at first, I didn't believe reports of viruses spreading via
JPEGs, but yup, it was true.  Thanks, Microsoft!).

  -spc 

[1] Never got any in my day-to-day activities, but there was an outbreak
at the university I attended in the late 80s.  I managed to snag an
example and decompile it.  I have no idea what virus it was, but I
think I still have a copy in my floppy archives somewhere.

What, really? Wow. You were lucky!

I never owned a Mac of my own 'til my "Road Apple" Performa 5200...

http://lowendmac.com/1995/performa-5200/

... in about '96, thanks to Apple's "Platform Club" for UK journos.

However, in the preceding nearly-a-decade, I supported & maintained
plenty of 'em. Virus infections were plentiful, by a wide variety of
viruses, and there were a wide variety of anti-virus apps in use.
Symantec Antivirus for Macintosh -- SAM -- was the most common
commercial one, but there were others. Virex and Disinfectant were the
most common freebies. There were both disk and file viruses, as well
as Trojans.

And when Mac Office 98 came along, there were macro viruses too.

Exactly. This. I agree. MS-DOS was a single-user OS without background
processing, but it had legions of viruses.

I don't think CP/M had TSRs as such...

Win 3.1 on a 386SX, no problem.

Win 95 on a 386SX: sheesh. You'd need the patience of a saint.

Early in my time at PC Pro magazine, I actually benchmarked 95 versus
Wfwg on a 386 with 4MB. We had to hunt for a PC that old, and borrowed
it from a friend of the editor.

Amazingly, app loading was a hair quicker -- 95 had smarter cache
management. But it wasn't fast.

Well, TBH, I did some of that consultancy myself. I didn't dump any

At the time of the "Michelangelo" panic, it did not appear to be in the

Berkeley student computer labs were retained for analysis)
The AV companies had copies, and they provided them to each other 
and to the media.  It wasn't until later that copies started to leak out 
into the wild.  In fact, we speculated that what was being found were 
wannabe variants, created from "Stoned", and INSPIRED by and after the 
panic.
The ones that we finally ran into were blatently obviously simply slightly 
modified versions of "Stoned", but THAT aspect was never mentioned by the 
AV companies nor the media during the panic.



Oh and the local guy that was involved at a high level with the DOS Virus 
group, he said at a party that had a bunch of DOS virus authors John 
MacAffee was there partying with them. No proof and he probably wouldn't 
admit saying that today (was told to me in the early 2000s).


Wouldn't be surprising.  I knew one fellow, with journalistic ties, who 
partied with both groups.  He threw a Comdex party at the Landmark Hotel 
with a lot of strange people.


There were rumors at the time, that McAfee was involved in creating 
"Michelangelo" and the panic.  But, until there is some evidence, I would 
give him the benefit of the doubt; and there's no way to ask him now (he's 
currently a murder suspect fugitive).




Creation of the "Michelangelo" variants that we saw did not require any 
expertise, just some disassembly of "Stoned" and some trivial patching.

Creation of the PANIC was an impressive feat of showmanship.

THAT (creation of the "Michelangelo" panic), and Harold Hill of Meredith 
Wilson's "Music Man" ("You've got TROUBLE, right here in River 
City") really helped train a lot of people how to make money off of Y2K.
The college probably spent more than $300 average PER MACHINE testing and 
preparing for Y2K!  (Since there were friends and relatives of upper 
officials working with the contractors, exact amounts spent were not 
clearly revealed)

Lest this turn into another chapter in Mac vs DOS:

- Yes, classic Macs did get viruses. But as a user of a classic Mac since
  1987, I think I encountered one exactly once and my experience was not
  unusual. They just weren't all that common and nearly everyone ran Virex
  anyway until Mac OS 8 days when the platform had little or no relevance to
  virus authors.

- You may not have had a command line, but it was perfectly possible to get
  under the hood. You could mess with resources in MacsBug or ResEdit, shuffle
  INITs and CDEVs, whatever you like. Such tools were easy to get and freely
  available. Whether you *liked* the resource/data fork split is a matter of
  preference but they certainly didn't prohibit mucking around by the
  knowledgeable and the structured nature of the resource fork in some ways
  makes it easier.

- No, pretty much everything was *not* just shareware/commercial. Look at
  UMich or Info-Mac for a nearly total refutation of your statement. Freeware
  existed in quantity commensurate with the platform's penetration and Apple
  certainly did not discourage it in those days. I have mirrors of them which
  you can check out:

was at least 8 of these from one author who was just a bored Navy guy. So 
take the # of viruses with a grain of salt. But BBSes did have collections 
of them, and I'm sure you can still find the huge zip files of them 
somewhere.


There were utilities like Virus Creation Lab that had checkboxes and would 
crap out assembly code or something that you would then take the output 
over to MASM or the Borland Assembler and compile. So who knows how many 
of the DOS viruses came from this.


I remember doing a lot of BBSing, and trading stuff with friends and never 
saw a virus. There was a case where the computers at Sears had the stoned 
virus or something and everyone in the area was excited to go over there 
and get a disk infected with it.


Of course BBSes always had the virus scan door. Ahhh fprot. And also the 
zip files that never stop expanding :-)


Oh and the local guy that was involved at a high level with the DOS Virus 
group, he said at a party that had a bunch of DOS virus authors John 
MacAffee was there partying with them. No proof and he probably wouldn't 
admit saying that today (was told to me in the early 2000s).

Its highly unlikely as first it would have to install itself and do so
without corrupting the OS.
CP/M-80 is a machine monitor with a file system and lacking most of the
usual
read the disk and "do something" automation.  The only automation in CP/M
is logging a drive which is reading the directory and mapping used blocks.
So the initial load would have to be performed by the user.  Trogan maybe,
social engineered for sure, virus no.  The key is you have to actually
execute
a file for action to happen.  In CP/M you can disk dump sectors and never
execute them, formatting is even more benign, the disk is never read save
for a post format verify.

There is no boot block save for system tracks and even then the OS is not
wired to write them without a utility so other than boot in rom(usually)
its kinda hard to pollute the disk though powering off with it in the
drive usually
will kill a sector making it unreadable.

There are many other OSs that equally as crude such as Northstar Dos or
for that
fact OS/8.  Old machines do not evaluate like current winders, linux,
OSX in that
perspective.

The extreme opposing end of the spectrum is a VAX running VMS/OVMS the
level of protection is high enough that you would spend much time and
effort to
find the way to get something above the user account level.   In that
case you
can pollute your self maybe share with friends assuming you don't user
crash first.

 If its a PC and running M$ it has it...  I don't collect them but have
a few oldies for the utility they present.
Even the mainstay PCs in use are linux based.  For those times I need
winders VMware/Openbox virtualization
keeps it well contained.

The rest of the hardware is DEC PDP-8f, Qbus PDP11s (11/03 through
11/73) and Qbus VAX plus 3100series.
The S100 gear runs CP/M as do the 8080/8085/z80 SBCs so no risk there
the remainder are odd things like
IMSAI 3035 control computer Ti9900, 6502 and others that virus/trogans
mean nothing.  I can't Imagine
malware for my AmproLB+ or Kaypro4/84  would look like.  In general if
its not internet connected its  very
low risk and if it can't run M$ OS on intel its even less risk.When
I find a bug using the PDP-11 running RT11
or the Vax running VMS makes it really easy to dissect the code without
worry of it escaping.

For those times I wish to visit a site that is flagged as dropping
malware using an expendable virtual machine
(copy of one) has proven both safe and handy.

I disagree.  I see nothing about "a single-user OS without background
processing" that would prevent a virus from infecting other programs,
even including the OS, when it's run, and potentially doing something
else as well.

Perhaps you are using some meaning of "virus" other than "piece of
software that infects other software to propagate itself"?  That's the
only meaning that makes any sense to me.

> Just wondering are you guys not running AV SW on your old HW?

I am not.

But then, because of my interests, the old hardware I keep is stuff
like Sun SPARCs that are powerful enough to run a real operating
system.  These are (a) inherently invulnerable to most of the malware
(including viruses) out there because they're not x86 Windows and (b)
difficult to attack with targeted malware because they are real OSes
with real interprocess protection, file protection, and the like.

Probably not impossible; all nontrivial software has bugs.  But I have
no reason to think I'm likely to be targeted by anyone with the
resources (= skills, mostly) to effectively attack my OSes.  And I'm
familiar enough with their operation that most successful malware is
likely to be noticed relatively soon.  And if I am somehow targeted by
the likes of letter agencies, there are much weaker links in the chains
for them than the things malware attacks.  And "AV SW", even if someone
produced one that ran on what I run and I were willin gto run it,
generally isn't going to notice custom-designed malware anyway.

No no no -- hang on.

Classic MacOS was appallingly vulnerable. It had no user-account security at 
all, and every disk had a tiny bit of code read and executed when it was 
mounted, AIUI, to customise the icon etc.

Personal computer viruses more or less originated on the classic Mac.

But OS X is effectively immune to all of them, and AFAIK there are no true 
viruses for OS X even now. But you need to use a narrow strict definition. 
There are many Trojans, but they need to social-engineer or trick the user into 
agreeing, clicking OK and entering a password.
That's not a virus if it requires user interaction to propagate.

Ditto there are sploits and worms that attack OS X servers, but since OS X 
servers are fairly rare, so are the sploits. And OS X has a much-modified 
FreeBSD userland underneath it, and some of those componets are vulnerable too.

So it's a bit of a hair-splitting argument.

What it is _not_ is plain marketing lies, such as "Windows NT is a microkernel".

I still have sealed packs of installation software for very early laptops with 
DOS. Some of them probably have the Stoned virus on them. I used to have 
factory original CD install disks from Zip drives, but I threw them all out, 
because they were all infected with viruses. Iomega was kind enough to send me 
clean install disks, after I mailed them back one of the infected disks. That 
prompted a huge recall, back in the 90s. I remember seeing web screens in the 
early 2000s from viruses; one was a picture of Zeus holding a lightning bolt 
with the caption "Watch out for Zeus, he will kick your ass!" Another was a 
picture of the old Kilroy was here, but had the caption of Kiljoy was here. 
Kiljoy would stay on for about 5 seconds, and then gradually all the network 
services would be stopped and then deleted from the computer.

I wouldn't dismiss it if you're using images or any used software. Yes some 
platforms are more susceptible than others but unless you have no hard drive, 
power your system off after every use, and never switch disks while system is 
running it's still something that can infest your originals or archive.
Dan's great collection of cpm is a good example of something that ended up 
passed around the community and had a few infected images.  Depending on 
whether it's a file, boot sector, MBr or TSR it will different and potentially 
detrimental impact.
I stopped archiving my Amiga disks but at a place I worked that had Amiga 
systems some kids brought in lots of games (some cracked) and while we didn't 
allow that it was spring break and they had finished their work. What's the 
worst that could happen? Kids slowly starting to walk up and say their computer 
says it's infected with a virus.
Probably one disk but who knows how many were infected after that. Took me 
longer just to find an antivirus for the Amiga than to get the systems cleaned 
lol but still, an unexpected pain.
One of the best preventative methods if the software doesn't need to write to 
the originals is write protect the floppy.  But buying used, who knows if the 
previous owner was computer savvy or safe.

Fred,

You nailed it, panic in the streets by people that should know better.

Back when I always though he was a criminal and behind it.

Also if anyone destroyed a drive or media with it it was out of shear
stupidity as a wipe/reformat
was all that was needed as the boot-block was not special it was just
another block on the media.
Floppies with it were bulk erased and reformatted.

My favorite formatter was my S100 crate with CP/M,  Its impossible to
give a single user OS
without background processing a virus.

I got a lot of free drives around then.  A few are still in use.

Well, no.

My vintage machines are, TBH, rarely powered on and I'm considering
getting rid of almost everything. I don't have my own house any more.
Most of the collection had gone already. My vague plan is to mostly
restrict it to portable/battery-powered kit from now on -- as they're
much smaller!

For things like Cambridge Z88, Psions, Amstrad NC100, Sinclair
Spectrums etc., it's academic. I'm not aware of either malware or
antimalware for them. Most don't support disk drives anyway -- or as
in the Spectrum, there were dozens and no standard, so software
couldn't adapt and none were so dominant as to be worth targeting.

I don't have more than 1-2 vintage machines able to run DOS or Windows
and mostly wouldn't want to!

The Macs should do, yes -- but then most of those are going, I'm
afraid. I don't have the space any more, and when I did, I never used
them except when fixing them up to sell. :-(

Just wondering are you guys not running AV SW on your old HW? I personally run 
period specific AV SW on my older machines. Granted I have mostly IBM 51xx

Since I get most of my stuff for these machines from dubious sources (e-bay,

I used to work for AVG; I can ask if you like. But yes. Also, they
include malware signatures from other systems, in case of attachments
etc. which can't infect the host machine but could if passed on to one
of the target OS.

Side note...maybe 6 or 12 months before the big virus scare I called McAfee
on the phone and spoke with him about a virus I found on a GRID laptop that
I found was copied to 4000 similar  machines out in the field where I
wokred. He emailed me his latest test iteration of his software, a copy on
a scratch disk.  It was a very early version.  I had no idea of course of
his future, but I was impressed with his software because it was light, no
install disks and he knew his stuff.   We were talking about how to inject
his antivirus prpgram into a program I wrote to update laptops remotely by
modem, and how we could send virus updates via this process.   It was
getting impractical to keep sending me disks and we needed a better way.
You could not buy his software
Viruses were starting to get more numerous.  I don't know if he had just
started his company, it was not public or anything yet.  In fact I got his
number inmformally from a manager at a company called Sales Tchnologies out
of Atlanta, I w as working with their sales tracking program they were
already using my "mass update" system to manage their software and data
updates.  That's where the virus came from.   Fun times all MS DOS based,
btrieve database, Sprint Internet exchange for free phine calls inbound
from anywhehre in the USA... I also remember building and compiling Sales
Tech software version updates on a xerox workstation.  When I left they
offered me the Xerox but I remember thinking what would I ever do with
*that* old piece of junk?  "Well Bill you're the only one who knows how to
use it so we will just throw it away then, are you sure".."yah, my

I didn't think modern A/V products included complete historical sets of
signatures. I'm sure they can deal with ancient, simple bootloader
infections and such, but at some point I'd be concerned there's a gap
where something might be too new to be detected by the simplest

to clean old viruses that way.  Scan before you use on an older machine,

Not to rain on anyone's parade, but speaking as an owner of probably one of
the first Sol-20's in the UK I would have to comment that the wood (which we
always thought was a nice touch) was actually quite light in appearance and
weight and if anyone had suggested wharf wood at that time I am fairly sure
the suggestion would have been met with a degree of scepticism as would the
suggestion of gun stock wood (I had achieved my marksman status by then and
had some small experience of the feel of the stock in the hand and
shoulder). For all that, I liked the SOL-20 as the best word processor on
the planet at that time (with the Electric Pencil ROM) as it took great
advantage of the VDM-1 memory-mapped display board to achieve what products
like WordStar struggled for years  to do. In fact, we often used to marry
the VDM-1 to the Horizon for that very reason - that and the fact that we
could then play ATC (Air Traffic Controller) on the North* which was a great
mapped video game unavailable to serial terminals.

It was also liked because it had a great keyboard with a good feel and, turn
and turn about, could also have the North* drives bolted on to make a great
little twin drive system. Another advantage was that we didn't have to
solder up all the boards and assemble it like the IMSAI and some of the
North* boards. I did love my IMSAI though, but the 8080 CPU was a drag as
everyone was gung-ho for the 'new-ish' Z80 even though CP/M was still in
8080-land. Then came Cromemco and everything changed with CDOS and Cromix.
People still wanted CP/M though - I recall even now assisting with porting
CP/M to a Cromemco Z2 I took down to the Byte Shop in London one weekend. Of
course, my IMSAI never flew better than when it was filled with Cromemco
boards and a 299B drive on the side :) - those lovely blinkenlighten!

Anyhoo - back to the SOL-20 - we always figured that the reason that the
wooden side panels were featured was simply because the Horizon (the Big Dog
at that time) was available with a very attractive wooden case cover for
those who preferred something other than a functional blue metal case (in
fact strangely remarkably similar to the blue of the SOL-20). Of course,
although opinion may vary, either was arguably more attractive in an office
than the metal mesh that SWTPC went with. I say this with some affection
since as I write this my foot leans against the case of my old SWTPC AC-30
cassette interface. The innards gave up the ghost long ago but I can't bring
myself to skip it as it brings back too many fond memories of a basement, an
SWTPC processor, a lovely dual 8" drive unit and FLEX.

In summary, if you don't mind an 8080 and you can get some decent drives for
it (we were never very fond of the Helios drives) a SOL-20 is a very nice,
well designed integrated system. I would have one again in a trice.

Re: Reasonable price for a complete SOL-20 system?

I don't think I have any other wooden computers yet. The seller had an 
interesting tale about the origin of the wood in these particular 
computers. As the legend goes, the father of one of the principals of 
Processor Technology had a contract to remove wharfs from along the 
Mississippi river, which happened to be made of black walnut. And thus, 
the SOL-20 received stylish black walnut side panels, hopefully without 
too much lingering wharf smell. I don't know if the tale is true, but I 
have chosen to believe it.

That's a new story to me, I always heard they came across a bunch of gunstock 
wood and were looking for a project.  The wood is very good condition for 
reclaimed wood that made up a dock that was near water and in sun. I have seen 
old docks and that wood is good for kindling and not furniture.

Still would be good to try to confirm the story.

Cheers.
Corey


I agree.  Even if the wharfwood was 
useable, the amount of working
it would need over other forms would not 
usually be considered worth
the time, especially for such small 
pieces.   Also, walnut is not

a preferred wood for dock building.

I believe that it has a Morrow Disk Jockey controller, and one or two external 
Morrow drives marked "Thinker Toys" on the back (not sure whether one or two 
are part of the offer yet).

Anyway, thanks for the input, everybody! I've made an offer, and I'll post an

Boot disk is easy if it's a Northstar.  There are enough of us who can help out 
with that.  Micropolis are also easy.  I can also help if it's a Helios.

Keep in mind since it's not currently confirmed working that effects the price. 
 If there is no scratches or rust on the system it will be worth more can be a 
lot more, minimum 1000 to 1500 in non working condition.  Early Sol-20 were 
rust buckets both on the case and the chassis.  I usually can find non working 
rust bucket for about $500.   I can usually get them working on a few hours.   
A really good condition with manuals and confirmed working Sol-20 currently 
sell for more than 2k.   Monitors don't count and can be found cheaply.  Heck I 
used a $100 LCD screen mounted on the wall for the longest time with one so I 
wouldn't scratch the perfect top on one of. One.  

The disk drive can really affect value.  If it's a Northstar system, then maybe 
add 400 bucks the most.  If it's a Helios.  A working drive can be priceless if 
the drive is still the original Persci one.  Non-working Helios can be like a 
trip to vegas.  They have a glass voice coil which tend to damage if not 
shipped correctly and plastic eject gears that split.  I would pay about 1k to 
1500 for a non-working Helios including the two cards depending on the 
condition of the case.  I generally assume a non working drive as a core drive 
for parts and if the glass isn't broken and the gears aren't split it's a 
candidate for a complete overhaul including bearings and that takes time and 
skill.  I've been working on one on and off for about a year now, putting a few 
hours in every few weeks or so.  

I couldn't even venture to guess the price of a working Helios.  There are less 
of them around than fingers on my hand and toes on my feet.   

A few more things to note.  Assume the keyboard needs new foam, no big deal.  
Check the wood to make sure it's not cracked.  And make sure you have the 
personality module included.  

Good luck,
Cheers,
Corey

Subject: Reasonable price for a complete SOL-20 system? 

I have an opportunity to make a "reasonable offer" on a fairly complete SOL-20 
system. It would include a floppy drive cabinet and some software, but no 
monitor. It's a "working when retired" system, so I assume that the keyboard 
has died of old age and some capacitors might have dried out; none of that 
bothers me, but it implies that it's probably not a turnkey system. I have to 
make the offer or not by tonight, based on when the owner is leaving on a road 
trip that will pass near me, with or without the system loaded up in his RV.

Now the problem is that I haven't been following SOL-20 prices, so I don't know 
what a reasonable offer might be. The only prices I'm aware of are the various 
buy-it-now prices I see on eBay, some or all of which I suspect are from 
sellers looking for top dollar and then some.

If any of y'all can help me figure out a reasonable price range for a 
complete-ish but not necessarily running SOL-20 system, I would appreciate that.
