There's an easy solution to that ;)

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.

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.

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!"

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 :-)

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.

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.

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.
