I will have to dig out he small computer handbook from the Dec section
at smecc library and study up on it again! the brain cells are foggy!
another nice go with to display with 8s is the DEC logic trainer
We somehow ended up with a few of these... one goes next to a 8 the
other in toys robots and trainers display and one for offsite which
leaves one extra for trade!

Not sure how much of a bus it got.

The 8/M came both with or without a front panel. I've got both, with the
front panel-less version connected (on occasion) to the front panel version
as an expansion box. 8/F is identical except for color.
There was a memory expansion box for the 8/L that is reminiscent of the
front panel-less 8/M, though it has four field switches on the front and no
key switch (the 8/M just had a key switch and a SW switch).

yea... poor 8 s was 20 microsecond cycle time....
the S stood for serial buss as I remember it.

Does anyone recognise these DEC cartridges?:
http://www3.telus.net/~bhilpert/tmp/deccartridge.jpg
Any details or knowledge of what systems they may have been used with?
They're definitely digital, note the logo on the nearer one on the right.
I can't recall ever having seen them. They're associated in this instance with 80s-era biomed analysis.
Also, anyone know what processor may have been used in a Becton Dickinson ARTIFACS 440 cell-sorting (FACS) rack?
We're speculating there may be an embedded LSI-11.
Rob and I are assessing some surplus/scrap equipment for rescue but haven't been on site yet.

First, my sincere congratulations! This is a real contribution, and I doubt it
was trivial to accomplish.

These sound so cool I'm tempted to buy one, even though I don't even own a
PDP-8! :-)

Someone mentioned -12's and -15's?
I don't (yet) need any -11 ones, although at some point, I might need an
11/20 one (I have a line on an 11/20 that spent a lot of time outside, so its
front panel is sadly very faded).
The thing we really need to find now is a source for the special switches
that DEC used in the front panels of the machines of this generation.
Electrically, they are just standard SPDT switches (usually two-position,
although for some - e.g. Deposit/Start - they are momentary-contact
spring-loaded); the real issue is the mechanical fastening, which uses a
special front plate (albeit on a standard micro-switch body).
I have a number of different ones in my machines, from various manufacturers,
but I have had no luck tracking down new ones through the part numbers on
them (they seem to be DEC part numbers, or adaptions thereof). I have asked a
number of people, but nobody seems to have spares/extras.
Anyone know of a source?

I just got a Compaq Portable 3 (286).
I need to edit the contents of what will be the C drive when dos boots,
though it probably doesn't have a file system on it.
Anyway i'll need to boot up from a floppy because it has a pick r83
system on the C drive. Not sure what the system is, so fdisk and some
simple tools like that would be nice too.
Anyway any help would be appreciated. I'm searching for someone local
with 5 1/4" floppies and blanks I can use, but if one has a disk i can
get from someone I'd be glad to send compensation.
For Pick folks (Mr. F15) I don't know the sysprog password, and need to
null it out.
I may pull the drive from another system I have that I do know the
passwords for, but this new system I just got is working, and I'd like
to log in and see what this system has and back it up.
Pleasantly surprised it has an AST 6pack in the expansion (included) in
the kit.
thanks

Hello All,
My googlefu has failed me in trying to locate actual drivers for download
for this card. This was a TIGA (34010) based card w/ built in VGA (so no
pass through) with 1MB of VRAM and 2MB of DRAM. I believe there were DOS
utilities, Windows 3.x drivers, and SW specific drivers (e.g. AutoCAD). OS/2
or NT drivers would be fantastic but I doubt they are out there. TIA!

So I have a busted MSV11-P, and I needed the FMPS to work on it. There is one
online, but on my computers, it was extremely faint, and very hard (almost
impossible) to read.
So I have worked on it some, and I have a new version here:
http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/MP01239_MSV11-P.pdf
which I feel is much more legigible, and is also a lot smaller (3.5MB instead
of 36MB).
The default page size is quite small (I have no idea why, I didn't do the
re-conversion to PDF, I don't have Acrobat), but if you blow it up to about
300%, it still has good resolution at that point, and it's quite readable -
all the signal names, pin numbers, package numbers, etc are quite legible.
It doesn't have as much resolution hidden away as the original, but for most
purposes, it seems quite acceptable (in fact, more so in some ways, given the
increased legibility). I was interested in producing something readable, and
easier to manage, and I think this new version succeeds at both.
For those who are interested in the details of what I did (because I've seen
other FMPS scans with this issue, and it might help someone down the road),
after first saving all the pages as individual images (like I said, I don't
have Acrobat, so whatever I did had to be done with something else - and I'm
not sure Acrobat can do what needed to be done to make them legible, anyway),
I started out by trying to simply increase the contrast. That didn't do
anything (at least, with my image tool).
Looking at the page images under magnification, I discovered why: the areas
of ink (lines, letters etc) were actually (in the scanned image) a stipple of
white and black pixels, which together produced the (un-readable) light gray
printing of the original. So the contrast enhancement knob didn't do anything
- each individual pixel was already quite light, or dark.
So I used something called an averaging tool (which takes small groups of
pixels, and averages them together), with a small averaging box size (I used
2x2), which converted the ink areas to a uniform grey; I could then use
contrast enhancement to bring the printing up.
I then reduced most pages to 40% of the original size, since the originals
were scanned at 600 dpi, in 8-bit/pixel grayscale, and were pretty huge. (I
didn't go that far on a few pages - the PCB images - which could use the
higher resolution. Also, if you want the full resolution, the original scan
is of course still available.) In addition to making the images smaller, this
actually increased the crispness of the printing, since the reduction
sampling process got rid of a lot of the jaggedness that the previous steps
had left.
I finally converted the resulting images from 8-bit/pixel grayscale to
1-bit/pixel black-and-white; on inspection of the two side-by-side, this lost
a tiny bit of definition, but I felt that the reduction in size was worth it,
plus to which my image tool has compression for 1-bit/pixel B+W TIFFs, but
not for 8-bit/pixel grayscale TIFFs, so I won doubly on the size.

Hi folks,
ISTR that DHCP was introduced in TCPIP-5.1, which was included on the 7.3
hobbyist CD. But I have a 7.2 CD?.
I've installed VMS on SIMH on a G4 iBook (because I can), but then I
remembered (yet again) that 7.2 doesn't have DHCP, which is a pain with a
laptop on WiFi.
So I'm hoping to find either (a) the kit to install TCPIP-5.1 or (b) a 7.3
ISO image on a big enough pipe for FTP. :-) Can anyone help? Oh, and if
you're looking for 7.2 (VAX) I have that?. Thanks! -- Ian
