There's an easy solution to that ;)
The first versions were for the National 320xx
CPUs. This ran on the 6205's, 6130, and 4132. Later, a Motorola
68000-based verson was released. It ran on the 2nd-generation machines
-- I can't remember the model numbers of off the top of my head. These
machines came in between the earlier National-based machines, and the
XD88 series machines, which were based on the Motorola 88000 CPU.
Indeed - the XD88 is actually "UTek V", and I'm not sure if the 'V'
is just a
UTek version number, or implies that the OS is tweaked with features more in
keeping with the SysV line.
XD88 machines were quite powerful, and had really nice
graphics
processors that made things like 3D solids modeling run really nicely.
Graphics performance was very high compared to many other vendors at the
time.
The machine's certainly lovely to use (although mine's a lowly /10 and lacks
all the serious 3D hardware) - it feels amazingly responsive compared to what
such as Sun were doing at the time.
The chap who contacted me actually worked on the 3D hardware microcode; he
said that for a brief period (of mere weeks) the XD88 was probably the fastest
3D platform out there, until SGI came along with a new model and blew them out
of the water.
Unfortunately, Tek never really knew how to market
computers. The Tek
4051/4052/4054, and to some degree, the Tek 4081, were the only real
Tektronix computer products that were market makers.
The way my engineer contact told it, Tek management were totally unable to see
anything except terminals - even the design philosophy forced on the XD88 was
that of a 3D terminal coupled to a UTek compute engine via a
not-particularly-quick bus.
Management even had a slogan: "KISS A RIJAT". "Keep It Simple, Stupid - And
Remember, It's Just A Terminal!"
Utek was very BSD 4.2-based. The XD88 version
adopted some SVR4 stuff
both at the utility level, and some system calls.
Aha - see above. I did wonder. (I keep doing this - I read a bit of a post,
start a reply, and then read the rest of it as I'm replying :-)
Tek scrapped a lot of machines. Some ended up going
up for sale at the
Tektronix Country store for fractions of cents on the dollar. Some were
sold at "fire sales".
I really wish they'd kept at it. Whilst they perhaps couldn't have competed
with SGI longer-term, they were heading in the right direction and probably
could have found a niche making systems with good graphics support where the
overkill of an SGI monster wasn't quite needed.
I'd love to find a Tek XD88/30 though with all the serious 3D bells and whistles.
I have a working 6130, 4132, and one of the 68K-based
machines. The
biggest problem with the 4132 and 68K-based machine (I wish I could
remember the model number) is that the 1/4" cartridge tape drive
capstans turn to goo.
Hmm, mine's OK in my XD88. With those sorts of drives it seems to be totally
random as to whether you get a bad one or not.
The 6130 used floppies for loading up the OS. I still
have all of the
floppies (they've been imaged), and they still work. I have cartrdige
tapes for the 6130 and 4132 Utek versions
You're lucky. My XD88 came with no OS media, no docs, a failing hard disk, a
trashed filesystem, no knowledge of what the root password was, no mouse, no
display, and no keyboard. It took quite a while to sort that lot out :-) I'd
still like to find OS tapes for it sometime, but don't hold out much hope.
My box was owned by IXI and used as a development host for their X.desktop
software, so it has a minor interesting role in computing history I suppose.
