Interesting topic, albeit somewhat off-topic for the list. (My apologies for
continuing it... :-)
Some disruptive technologies are subsets of others; e.g. transistors are in
some sense a subset of electrical (altough, as Chuck points out, they also
draw on materials science). And how far back do you want to go? The discovery
of metals certainly had a huge impact, albeit that it was many thousands of
years ago now!
But among the big ones for me are electricity, which almost has too many
subsets to count (e.g. long distance communication, starting with the
telegraph - read "The Victorian Internet" for a good look at how that changed
the world), the printing press (information technologies in general have
outside weight, since they affect so many other fields), the internal
combustion engine (which has physically re-shaped entire civilizations,
especially the US), with all its subset (e.g. the airplane)... too many to
think of, almost!
And it all started with sharp stones... :-)

I am somewhat ashamed to admit that before today, I had not (that I can
recall) heard of him. And I see there is no full-length book on him. A
hole waiting to be filled, as it were...

On the back of Roe's question; didn't want to hijack his thread.
I was browsing eBay and came across this very unusual looking Unibus card
(?)
http://www.ebay.com/itm/Vintage-Computer-Memory-Digital-DEC-logo-1216988-bo…
I'm really curious what all those SIP hybrids are running down the one side
of the board. I see it's got no less than 8 74181 ALUs so I figure this has
got to be some kind of processor?
Perhaps a prototype or simply an obscure hop-up processor for Unibus
machines similar to some of which were marketed for Q-bus with i.e. MC68k,
NS 32k, MIPS CPUs (KN210), etc.
I tried to do a little research about i-con on the Web but I'm coming up
blank.
Anyone know what the heck this thing is? Just curious.
Thanks,
Sean
My advisor was given an old HP83000 IC tester a few years ago and I got
stuck with trying to figure out how to evaluate if it is worth trying to
set up.
To that end, I am investigating the HP C360 visualize workstation that came
with it.
It is booting, but there are entries in the fstab that imply that there
were more hard drives.
It came with this hard drive array: http://imgur.com/a/0JSZW
I am having trouble even identifying the make and model, let alone finding
some sort of manual.
Anyone got an idea of what is going on here and possibly where I can source
the correct cabling for it?
The workstation has 2 scsi busses, an ultrawide single ended and a narrow
single ended.

I own a Hickok 533 and a few other testers, as well as a GR vacuum tube bridge, to ride herd on many vacuum tubes stocked for many vacuum tube instruments and antique radios. I don't get as sophisticated as working with 8s (though I did care for a couple of pdp-8/m systems 30 years ago), I just wrangle some electronics with dedicated microprocessors from the 8080/8085/Z80 family.

I just realized I haven't gotten a message from the list in over a month.
wondering if I got dropped or the list is down?

I have had my PDP-8 (no letter) since around 1985. As part of the deal I
got a little over 200 DECtapes. Most of these are SCOTCH 3M branded in
cardboard boxes and not DEC branded DECtapes in the clear blue plastic
containers. I have been thinking about moving this data to a permanent
storage location so I wondered how much space this would require. Turns
out to be about 57 million bytes and that would be without bothering to do
any compression.
The trivia question is:
Approximately how many DECtapes will fit on a single one terabyte drive?
As there are several possible answers to this feel free to reply on the
list. I will give my answer in a few days.

A Kenedy 9300 9 track tape drive, formatter, controller to emulate various
military drives, Univac 2049 (Canadian USQ-69 like terminal) and ZIP
emulator of tape drive may be available. The drive and terminal are large/heavy
so shiping isn't practical. If you just need parts for yours I may be able to
scavange. Its also possible that I won't be able to get anything. Equipment
is in Maryland near DC.
Contact me off list if you have interest.
Hi.
I went dumpster diving some time back. I saw an old "white box" 286
PeeCee with a MFM disk and a strange ISA card. I riped them out of the
box and took them home. I intended to reuse the MFM disk in my MicroVAX
2000. Then I noticed that the ISA card carries a IMST414 Transputer
chip. It looked to me like this PeeCee was the "head" of a bigger
Transputer system. (That I rescued out of that dumpster some years
back.) So I went back to that dumpster and pulled the other ISA cards
(disk, video, IO). I suspect that this ST-125 MFM disk contains some DOS
software to drive the ISA card with the Transputer. Plug all this stuff
into some generic old PeeCee and there you go...
The Transputer card is 8 Bit ISA full size. It has the T414, a bunch of
74TTL glue logic, 16 SIMM sockets, four populated, a button and a small,
round 5-pin connector on the slot bracket. It is labeled "Monoputer 2
v1.1 (C)Microway,Inc. 1988".
I am willing to ship this inside .eu for a reasonable "shipping and
handling fee". (Or in exchange to some SGI O2 RAM.) I don't wane make
money on this. I want this to go into good hands, ideally someone that
rescues and preserves any software from that MFM disk.
