Hello!
I sent an email about a month or two back to Al Kossow saying that I was starting work on the PDP-7 again. With ungodly timing I proceeded to come down with the flu, travel abroad, and move. So here I am again. ;)
I have come to the conclusion after some wire-tracing and so on, that this machine is smoking crack, and that very little is where it should be (except for core memory, everything seems right there). The processor has been modified ad nauseum, of course without documentation of any kind.
Therefore, I need to take out all the modules, all the wires, and start afresh (might be a good idea, anyway - - this way I can clean all the contacts properly). Thus, I need a wire-wrapping tool. Does anyone here have one?
TIA

MediaVision Pro Movie Spectrum (ca. 1992-1993) ISA video capture and display card.
Includes Microsoft Video for Windows 1.0 w/manual and Macromedia Action 2.5
Looks like the card was never used, but the software and box show some wear.
Sigma Designs REALmagic Rave VLB graphics accelerator with MPEG playback hardware.
Also have another S.D. card with no documentation that looks like the ISA version of the above.
This stuff was dumped on me by a neighbor who is moving -- literally showed up on my doorstep.
Free for the cost of shipping to anyone who wants it, otherwise, it goes to the recycler.

My BIL is getting rid of some older stuff, and has about 20 copies of
DOS 3.x. Anyone interested?
Also, we about half filled up a dumpster with old mono, cga, ega, vga
monitors and printers, along with some other ... stuff. Hardly a dent in
all the stuff here, but at least it is a start :). There is still about
1/3 of the space left in the dumpster and the project for the next day
is to fill it!
I found several Wang monitors, another NS Horizon, more IBM mono, CGA,
and PGA monitors, some NIB TI floppy disks, bunches of PC cards, another
ADM3, and a bunch of other stuff I hadn't seen in a while. This actually
gets to be fun seeing this stuff again ... almost like finding it out in
the wild :).
Worked fine several years ago, but now posts a 201 error and screen
distortion in the corner. Has one floppy and one hard drive. In good shape, looks like
it got dropped on a corner before the time I got it.
$3 gets it.

But I have no choice. The processor was modified with an improvised
API, and half of this was later removed (leaving the processor useless)
Also, an IPB (Inter-Processor Buffer) was made,
which connected it to a NORD-1, a not-quite-mini, not-quite-mainframe
machine. This has also, of course, been removed.
The CPU and IO planes, are, in short, FUBAR.
I have complete documentation of the wires, and of module locations,
they are all documented clearly in F-77 Maintenance Manual (which
you have on your site). They are easy to read, and give a complete
schematic of both the backplane, and the module locations.
There is 0% chance as is.

This is a REALLY REALLY REALLY bad idea.
It is hightly doubtful that someone completely rewired the backplane of this system.
If you start ripping out wires, there is 0% chance this system will ever run again.
For those of you that have/use/care about NewTek's Amiga Video Toaster,
and don't read slashdot, NewTek has release the source to most of the
software. For more info:

Several years ago I lent a friend an ADM-3 Terminal he needed for a project.
Yesterday he gave it back to me - along with "interest" ;-)
Here's the goodies he gave me:
IMSAI 8080 (with a perfect front panel)
IMSAI 8080 (with video console)
Digital Microsystems DSC-2
TEI S-100 bus system
Godbout S-100 Dual Chassis system w/HDD
Poly88 (Original "orange" chassis, keyboard, etc.)
FDE S-100 system (not a complete name - it just escapes me at the moment)
(2) Spare Shugart (SA800) - one is brand new in original box
Spare chips, ROMS, etc.
Literally hundreds of 8" CP/M disks
Documentation on all of the above
Thanks, Dave, for all the goodies!!!!

Oops! this was for Al Kossow. Sorry about that.
