they indeed produced both a beige and blue metal case. I have one of each as well as a wooden one. I iwll have to dig into my issues of Byte to check into N* ads for more info when I get back to Seattle again.

Subject: Metal Case Northstar Horizon
Someone mentioned some time ago a metal case instead of the standard
case for the Northstar Horizon. Can anyone confirm if they did put out a
computer in a metal case, and if so, (wishful thinking) how many they
might have produced? I have one here in a powder blue metal case similar
in color to the IMSAI, but I thought it was something someone just put
together. I talked to the person a few days ago that I got it from, and
he couldn't remember any details except that it came from a swap meet
many years ago.
Hi Y'all,
I just popped open an ASR-33 I picked up a few weeks ago. The tty ran
OK in local mode in the store where I found it but in shipment to me
something happened, it now free runs (runs free?). Maybe it's a loose
connector.
In the electronics bay on the right hand side, there's a printed
circuit board that runs from front to back. It's definitely a power
supply, and probably also an RS-232 to current loop converter. In
front is the line/off/local switch, and in back are several large
Molex connectors. I was surprised to see this printed on the circuit
board:
MITS INC
TELETYPE INTERFACE BOARD
REVISION 0
COPY RIGHT 1976
Does anybody know if this the Altair MITS? The date seems about
right.
Was it common to produce custom internals like this for teletypes?
Anybody have the schematics for this board?
Thanks,
Brian

Hey all:
I'm fixing up a Vector Graphic MZ machine and have a problem with the
Flashwriter II - all that comes up on the terminal is garbage when I
boot the machine.
Someone has the Flashwriter (1!) card on sale on eBay, anyone know where
I might find docs for this thing? I need to compare them to the
Flashwriter II to see if the Mindless Terminal changed between versions
or if the older board will work on the newer "terminal". Anyone know of
any docs (they're not on the Harte collection, alas) out there? Or any
ideas if this will work?
Thanks!
Regards,
Gord

Hi Bill
I've only had experience with DeoxIT. It seems to work
well but before these products were around, I used
DC #4 ( Dowe Corning ) silicon grease and also an automotive
product called SilGlyde.
You shouldn't use ordinary lubricating grease because
these have too high of a film strength. The silicon grease
used for heat sinks is not good either because of the
filler ( white stuff ).
Any of these will work miracles. I use this type of product
on most card edges and ROM sockets. I've even been know
to use it on boards with all socketed parts.
If you look back in the archieves you'll see that I've
talked about this stuff before.

At the time the page was created, no other Alto I's were known to exist.
Since that time, two are known to still exist in PARC storage, and one is
at the CHM.
The Alto I in that picture is now back in the Bay Area also. It was one of
mine at one point.

The image is on Al's site, but can't find it referenced in my docs. Anyone
know offhand?

Hi Marvin
How long do you expect to be gone? I was thinking
about making a weekend trip down to Santa Barbara
sometime later this summer to look at the Polymorphic
items you have.

Since I will be leaving for Europe (Hungary/Czech Republic) in several
weeks, the stuff I have listed on VCM will be expiring on 8/12. It would
be nice to see more names listing things too :).

Nice! Mine's NTSC and I need to build a game cable so I can plug it into
the tv card in my peecee. Wouldn't surprise me if it was dead.
It's been disassembled here:

'all' that circuitry can generate is 2 player objects, a ball object and
optionally a net object down the middle. Top stuff!
Cheers

I recently tried reading some CDs burned in 1998 or so,
on a nice SCSI Sony burner of the time, on Taiyo Yuden
media, kept in sleeves with no label or Sharpie, in a
fire-safe case (yes, I realize it wouldn't help except in
the lightest fire) in an A/C office environment. One of
five had an error. On the other hand, I probably didn't
check the original for read errors after I made it.
