What's next, purity tests and monthly check-ups to insure that
everyone's mind and body are innocent enough to own and sell
old computers?
If some Microsoft millionaire wants to pay stupid prices for
old junk, what'ya gonna do, resort to vigilante indoctrination
until they're willing to waste weekends searching thrift stores?
There's no use getting upset about the right edge of the bell
curve of Altair prices.

I hear this a lot, but I think it's just collectors like us whining (yeah,
whining, I'm guilty too) of prices for this stuff going up past the junk
range.
While I do not dispute that there are folks who have had some machine(s) in
their closet/garage/warehouse for some time, find out that it's worth money
now, and pop it onto eBay, I am not aware of anyone who is _buying and
selling_ classic computers for a profit.

I've been collecting radios, televisions, and computer equipment for
some years. I've bought and sold lots of different radios and
televisions, always to buy yet another more coveted radio or
television. I don't have the disposable income necessary to collect
everything I want and regardless of available resources, my interests
have changed over the years. What once bowled me over may have grown
passe` to me now. Anyway, I've funded the purchase of new and to
myself, better gear by selling off what I am no longer in love with or
just plain bored with. I have made a profit on some of what I've sold,
taken a loss on others. I've been able to better my collection without
denying my children milk and clothing this way.

Hello, all:
While looking through 1984 Bytes. I came across an ad for the computer
used in the bedroom scene in "Wierd Science". It's the Memotech MTX512. It's
a sleek black unit and appears to be based on the Z80A.
Does anyone know anything about these?

<================ reply separator =================>
I found another core memory board. This looks like it's also for the Data
General 800 but the name on it is Keronix. It says that it's 16K x 16.
For sale or trade, best offer. E-mail me privately.

The 465 series are generally considered to be excellent scopes. Tony was right, $600 is about the going rate, neither a bargain nor a ripoff (depending to a degree on the condition of the scope). When looking at a square wave, it is normal for the horizontal tops and bottoms to be brighter/thicker than the vertical segments. The linear speed of the beam when drawing the vertical lines is MANY times (sometimes hundreds or thousands of times) faster (in mm/second of beam travel) than when drawing the horizontal tops and bottoms, which results in a difference in the nature of the display.

_Very_ nice portable 'scopes. I never owned one, but I've used the 465,

That is about the 'going rate', I think. Not a bargain price IMHO, but
not high either. And considering that's what you'd pay for a cheap new
no-name 'scope, I'd much rather have the Tek.

Does the thickness depend on the vertical attenuation (is it noise coming
in from somewhere)? Can you resolve any structure to it by fiddling with
the timebase (in other words could it be noise on the supply lines from
somewhere - noise which almost certainly isn't at line frequency). What
does the spot look like in X-Y mode with no signal?

I can't think of another adjustment, but it's worth getting the service
manual and going through the performance checks in there. And also
checking for supply ripple, etc (yes, a second 'scope is worth having at
this point...)

S1= ON Boot to ODT 165xxx
S1=off Boot selected device 173xxx
s2=off for 11/24 use
s3 through s10 are starting add.

Try 173004g
or R0/ x Where X is the device # you want to boot from (0,1 etc. depending
on what unit has the system pack in.)
Then 173012g it will size memory as above then boot selected unit.
I am surprised you have the M9312 in that machine since you have 1 meg of
memory. Normally you would put the boot rom on the KT24 (M7134) and use
just a M9302 terminator.
I think I have a second 11/24 system technical manual around here but I
can't find it at the moment. I will keep my eyes open for it in the
meantime. It is to thick to readily copy and I use it to often supporting
several customers that are still running them in production to loan my only
copy.

I feel compelled to point out that I know all of the classic computer
collectors here, and I am only aware of one millionaire in the world ever
paying stupid prices for old junk, and he's the founder of some independent
web design company, he does not work for MS.

Normally, yes, that's what you'd do. But it is possible to use
more than 256 K without the KT24 memory map/bootstrap module, assuming
your OS never tries to do I/O to memory past 256 K. For example,
RT-11 SJ, where the extra memory is used as a virtual (VM:) disk
drive.

Ok... being somewhat bemused by the thoughts of a 'feeding frenzy', and
sadly short on $$ (as is all too common this time of year), and not
wanting to be accused of 'selling out' on eBay without offering to the
more civilized set first, and... (etc., etc., etc...)
Let's chuck another (yule) log into the flames and see how badly I get
scorched with this one... (quite the build up, eh?)
---
Deemed (reluctantly) surplus to the collection:
SOL-20, electronically restored and keyboard rebuilt
w/ P.T. 16kra memory card
- AND -
(so the eBay set does not feel left out)
*RARE* original Panasonic B/W TV/Monitor conversion from P.T. with
touch-plate power switch!
---
Not that I want to start a bidding war (or then again, why not?) so lets
say that it could be had for $600 plus shipping, with a possibility of
part/all trade for something similarly really cool! (tho I could really
use the $$$)
Then, if the feeding frenzy really starts, folks can start openly bidding
up the "ham sandwich"! B^}
"Call now! This offer only good thru noon PST Friday, 18-December-1998
or while supplies last! This offer may not be repeated! Operators are
standing by!"
