While our current leadership ranges from stupid and grasping to
downright evil and ready to shred our Constitution, many of us are
still capable of rational thought. He's a president, and while the
office deserves respect the man himself must still be judged on his
own merits. And, just my opinion, found severely wanting...
So thanks for the yucks, and don't bother writing to me directly.
Admiral Poindexter should be dispatching the brown shirts to have
a chat with me as soon as this message passes through his current
sieve. Now, where did I put that code for the old NSA line-eater
appender...
Sigh,

For a Gerber RS-273X Format document, see:

The X format contains all cad data, whereas the RS-274D format needs a
separate exellon-format drill file as well.

I have an MCA board here (probably pulled from a PS/2, but I really am
not sure where it came from).
Its marked as an Intel Above Board MC. And currently has 8 30 pin SIMMS
on it (1 MB each it looks like). From what I can find, I think this is
just a normal above board memory expansion card (max 32 MB?)
However, there is also a 50 pin IDC connector on it. Is that for
connecting to a daughter card? I just want to confirm that fact, and that
this isn't really some kind of a SCSI controller with a nice buffer on
it. I thought the Above Boards were just memory cards, but you never
know. (maybe if I could find something about them on Intel's site... but
their AboveBoards support section seems to have vanished)

Hi Eric
I wrote code for the development chip 8021 to
test the A/D. I never got one to actually give
me a true 8 bits. 6 to 7 someplace was typical.
I made a little fixture to plug it into as well.
The developement chip was in one of those funny
packages, like the 432's.
Brings back memories.

Hi all,
after searching the archives for info on osi and m/a
comm computers, i found this list and subbed to it.
i am into mini computers and ham radio as well as most
tech fields.
currently i'm looking for info and pinouts/schems on
the osi boards.
i have some spare boards form a osi m/a-comm 220c
and a oem of the same but am trying to get a "dbi
db80"
working.
the db-80 uses all osi drives,powersupplies and
boards,
except for the two cpu/terminal/comms boards labeled
"dbi inc db1"
the comp also has a ohio memory systems 10" hard drive
in it.
the machine did work in the early 90's then a strange
problem started" upon a floppy command the head would
go to the end of the lead screw and the stepper would
not stop!
now after 6 years in storage i tried the spare boards
on a backplane and nothing (great more work to do).
i thought the drive might be bad also so i searched
the archives on this list and read about the
serial/parallel interface that osi used - a-ha! that
why osi dosnt use the read data pin on the siemans
drive.
the drive did head load and step ok when i tested them
last week and i got a good index sensor pulse so
perhaps the controller was going.
if needed i'll recap and replace all the chips on the
cards (i hope the eproms (rom) are ok.
might anyone have docs on the osi boards?
or is thier any osi owners.collectors on the list
anymore?
if so i'll send the board numbers later.

Hi
That is why I didn't say that one should write a program
that reads scanned files, I said that one should have a tool
that worked from a mouse ( with human attached ). Most tools
that would look at scanned data would tend to make a lot
of small rectangles instead of correctly grouping the information
as a single large rectangle. We are talking about something that
a human can easily do but a program has issues because it
requires judgement.
The fact is that Gerber files are quite simple. They are
about as simple as one can get. Although I don't recall the
exact syntax, it is thing like goto to x,y; with aperture
wheel position 2 draw relative xx,yy; goto to u,v; with
aperture wheel postion 3 flash; and so on and so on.
I don't think one could describe a PC board any simpler than
that. I never said that an automatic tool should be easy to
write. I said that one could make a useful tool that would use
a mouse to locate and draw( snap would be nice ). One would
simply trace the pdf or what ever with the mouse.

Anyone know where I can find both the User Manual
and the Service Manual for the LaserJet 2 33440A Printer?

Hello, all:
While rummaging thought my stock of Commodore chips, I came across a
bunck of R6765 chips. I looked in some of my notes and I have "floppy
controller" written down and elsewhere "D765". Is this a Rockwell-badged
version of the NEC controller? Which Commodore drives was this chip used in?

Hi,
I just found this list. Very cool.
I mostly have early 90s stuff in my collection. A NeXT slab, a bunch of
Sun lunch box machines, stuff like that.
However, I also have a VAX-11/750 that used to belong to a university in
Oregon. It came with the UNIBUS expansion cabinet, a TU80 tape drive, a
SA482 rack, three RA81 and two RA82s, bunches of spare boards, loads of
field service and other docs and a bunch of the cartridge tapes.
When I get around to trying to bring it back up, I will just keep the
base cabinet and the TU80 and the RA82s (one operational and one spare).
I may keep the SA482 in case I get some interesting equipment that
needs a rack. I presume that I can pull the expansion cabinet off of
the base cabinet and attach the TU80 in its place. If so, if anyone
needs a UNIBUS expansion cabinet ... I dismantled one of the RA81 drive
enclosures. If anyone needs a RA81, I have two and a half. I also have
a RX02 (two 8" floppy drives) that I want to get rid of.
One thing that I am looking for is a drive bay front panel for a RA82.
I have one for an RA81.
Another thing that I am looking for is a Burroughs B1965. I worked at
Burroughs/Unisys during the end of life of the B1900s and think they are
cool machines.
Later,
alan
