And there's only so much you can do with PC's :-)
Seriously, It's obvious that the _real_ top end today is faster than the top
end 10 years ago. It's also obvious that the 'home computer' of today (which
is probably a pentium PC) is better than the home computer of 10 eyars ago
(say a Commodore 64). But it's not at all obvious that the home computer of
today is any better than a 10 year old top-end personal workstation or a
minicomputer, or a number of other things. And those are turning up very
cheaply if you know where to look.

I don't necessarily buy hardware on the grounds that I _might_ need the
facilities one day. As what I already have does all I need, then I see no
reason to upgrade (downgrade?)
And if I did ever need to display a 'photo-quality' image, I can find a few
systems around here (all over 10 years old) that could do it trivially.

This, alas shows how little you know about the state of graphics 10 years ago
Give me a break. I am _NOT_ talking about home micros. I am talking about
professional graphics displays with hardware anti-alliasing of displayed
objects. I am talking about 512*512*30 bit images. I am talking about
broadcast-quality TV images (if you should need to go to such a low scan
rate). I am talking about 3D displays with LCD spectacles. Etc, Etc, Etc.
I've had more than my fair share of eyestrain from impossible-to-converge
SVGA monitors. I've battled with the service manuals for _hours_ on some of
them and not been able to get the convergence right. I'm then pleased that
Barco, Fimi, Sony (the older ones at least), Philips, Moniterm, KNE, etc, etc,
etc did make decent, easy-to-set-up monitors 10 years ago or more.

AFAIK, this is a classic computers list, and not a classic home computers list
Anyway the PDP11 is a home computer now. I know dozens of people who run
one or more at home.
I've payed a lot less for any of my PDP11's that you'd pay for a pentium
motherboard + CPU. That's complete PDP11's with disks, realtime I/O,
terminals, graphics options, SCSI interfaces, etc, etc, etc.

Wait a second. ISA graphics cards are already getting hard to find. So,
presumably, if I have a not-too-old PC with an ISA graphics card and some
custom chip dies, I have to buy a PCI graphics card, a new motherboard,
a new processor, and either new memory or some SIMM converters. No thanks -
I'll stick to my classics where repairing consists of picking up the service
manual, finding the dead chip in about 10 minutes, and replacing it with one

Monitors can often be repaired for a lot less than the cost of a new one.
Yes, the motherboard will probably outlast the hard disk, but that's
(IMHO) because modern hard disks are darn unreliable (I've had several
die on me, and without a clean room there's not a lot I can do). That doesn't
mean the motherboard won't fail, though.

There was a thing that came out in 1979/1980 called an I2S model 70 image
processor. It used (in at least one configuration) _30_ bits per pixel,
although only at a resolution of 512*512 pixels.
If you're only used to home micros I can understand why you think old machines
can't display 'photo-quality' images, but there were plenty of larger machines
that are now turning up second-hand at prices that collectors can afford that
have significant graphics abilities.

Great idea to include peripherals. Never thought of that.
I would rather you see a sample of the book before making a purchase
decision. Please reply with your postal address and I send a few pages -
don't have scanned copies for faxing or emailing.

By 1986 1280x1024 color was about $25k and small (allowing for the 19"
monitor). MicrovaxII/gpx... now you can find them in dumpsters.

At $500 I'd have a killer PDP11. Most of mine are scrap/salvage or trades.
I'm letting a PDP11/23b go for very little as I have one and they are common
enough and powerful enough to run multiuser OS or one of the unixes out
there.

I got a working vs2000 from someone elses dumpster trip so they are common
and they can do eithernet, PPP, 1280x1024 graphics (color was an option),
6-16mb of ram in a 1cuft box witha 160w powersupply (small PC!). The real
trick is getting a disk (rd54 was the largest supported at 150mb) as SCSI
is there but not bootable other than DEC tk50 tape. The other problem is an
OS though DEC has made VMS6.1 available with a free license, compared to VMS
DOS is a toy! There are people doing a netBSD for it as well.
Other boxsized vaxen are 3100 and friends most being very high performance
(2.5-3VUP, a 780=1VUP).
larger MicrovaxII configs are common and generally free to cheap and most of
the same thing apply save for bigger. Even the BA123 boxed VAXen are under
500w in practice, since most pcs are in the 230-270 watt range it's not as
bad as it would seem. Other small vaxen in the "Sbox" incluude the 3400,
3500. they are faster and still pre-1990..
The older Vax 780/1/2/5 systems are three good sized racks plus and serious
power. The later smaller (slower) 730s are one to two short (40") racks
and under 1000w for mall configs (save 1 or 2 ra80/81 disks). RA81 is 200mb
IMS. The next faster was the 750 and that can also run on household power
but, just barely.

PANASONIC HANDHELD UPDATE:
This is the latest message from Mike who has the hundreds of Panasonic
HandHeld computers. In case its not obvious what's going on, I put in an
offer of $10 each for 50, $9 each for 100, $8 each for 150, etc. I don't
have $2000 lying around with which to buy them all up. I have a plan,
but first read what Mike had to say:

Dear Sam,
I believe the total number of HHC's available will be about 400.Based on
your offer I assume that for 150 of the units you would be willing to pay at
the rate of $10 for the first 50,$9 for the next 50, $8 for the next 50 and
$7 for the next 50 whcih would come to $1700 for 200 units.Would you be
interested in 300 units for $2000 even?To make the offer even sweeter I'll
throw in the memory expander trays with each unit.The cost for each tray
alone was well over $100 when they were purchased,as well as a quantity of
the MCM 68674 8K eprom chips that the programs were written on.
As always Best Regards,
Mike
------------------------------------------------------------------------------
END FORWARD
So here's my plan...anyone and everyone who is interested, reply to ME
(do not reply to classiccmp! People will hate you and want to drown your
pets!) telling me how many you want. Do this soon. I will save all of
your e-mails and then at the end of say, 10 days I will tally up the
total and make Mike an offer. So again...
Reply to ME only (dastar(a)crl.com)
Tell me HOW MANY of the Panasonic HandHeld Computers you want.
Do it SOON.
You have about 10 days.
Price will be NO MORE THAN $10 EACH.
I'll get back to everyone in 10 days or so.

hey, i went to your web site, but didn't find what i wanted. i'm looking for
dos 2.11 programs that will run off of a 3.5" floppy. most specifically, i'm
especially looking for games. any kind will do, but even more specifically,
i'm looking for text driven adventure games, as my kaypro 2000 LCD screen
doesn't do very well with graphics!! so, let me know what you can do for
me.. i really appreciate it.

I wonder if anybody here has the *exact* months of introduction of the
three first *real* home computers introduced in 1977:
a) the Apple II
b) the Tandy TRS-80
c) the Commodore Pet
I need them for a book on collecting home computers I am researching
for.
Thank you

Well some of my collection gets a good workout. The most notable is
the Commodore 64 running my BBS, the Silicon Realms, which has been
on-line for just over 10 years using 64s (this is the second 64, before
it the BBS was running on my then only 64 and my 128 for a while, all
the original computers still work.) I would say that this BBS is
probably one of the most stable low-end BBSs it can run litterally for
weeks (it is networked to other boards, mind you) without nary a crash.
Nowadays I can bump my commie BBS to 14.4k and have a 20mghz
accelerator to keep up with the big bards, but alot of that stuff isn't
considered classic yet...
Across the room (more like spin around in the chair) is the 128,
which I still use to program stuff on as well as create disks for people
and stuff, lately it has seen increased use.
A PET and a couple 64s made it out of storage for my last BBS
gathering and helped entertain attendees. (Many of the IBM gamers
fondly remembered and played on the 64s for a while.) I think I'll
bring more classics to future ones, (I hope to have asteroids for the
Atari by then, it has a 4-player game option).
------------
Currently most of the Commodore 64/128 users on the internet are
using terminals and connecting via provider's shell-accounts.
There is a version of SLIP for the Commodore and also a HTML viewer
(off-line from what I gather), but more and more word on bigger and
better things coming "real soon now". The Wave, a terminal for the GEOS
environment is supposed to have text HTML viewing capabilities, graphics
is a pretty big hurdle for our little machines, it's not in the size per
se (images can be scaled down), but in the volume of processing these
huge image files will require, many of which are 2 to 5 times our
computer's memory! But that never stopped the determined hacker.
