In the PC world, there was the TI TGA card.
I've seen them most often in arcade games. Several vendors used them,
including a couple of generations of Atari hardware (Hard Drivin', etc.)
Apple built an evaluation card for the 340x0 when we were deciding on
how to implement accelerated graphics cards. The decision was to use a
29000 processor (the 8*24 GC card).

Yet another project not completed. I have stuck the raw scans of
that section in with the rest at ftp://ftp.pdp8.net/misc/4010/ I will try
to clean them up next weekend. I think I found all the files from that
section but if not email me and I will find them.
Before I forgot about it I was debating on the best way to deal with the
foldout pages in that section. The big foldout pages in this manual
frequently had two separate drawings. Would people prefer that they be on
one big pages like the real manual or on two separate pages so viewing
and printing will be easier for people who can't print on the foldout size
paper?
Hello,
does anybody have bits for the TI 960B (not 960A) minicomputer, e.g.
software, schematics etc. ? I'd like to get this system running again.
Thanks,
Christian

But you mentioned "225"...As in Seagate ST-225? I've never heard
of stiction problems with those (I have used quite a few of them, and
I currently have a few in DEC machines as RD-31s)...I wasn't aware
that they could develop such problems. I will keep an eye on mine!

Oops; I also mentioned ST-225s as having stiction problems, but I
meant ST-125s and ST-251s; although I've had my share of other
problems with ST-225s and 238s, stiction wasn't one of them.

Rumor has it that 9000 VAX may have mentioned these words:

Between 10K and 100K times - IIRC, CompactFlash has virtual sector mapping
with load-balancing to attempt to reformat the sectors evenly(ish). Dunno
about the others...

Depending on how often the machine is used, it may very well last a long
time... but if you're still worried: MRAM. The older 5V stuff has writes
into the millions, IIRC, and some new 3.3V stuff is listed as "nearly
unlimited" - you can interpret that as you wish... ;-)
Freescale (read: ustabeen-Moto) didn't list a maximum write life in their
datasheet for the 4Mbit part they sell.
Not the cheapest, but it's not outside of "affordability" IMHO.

My old DEC 486 pizza box had a rather large video card
w/an 020. Emulated base VGA but thats all, which made
it something of a dog.

It's nothing like that at all.
He has spent the last decade collecting lots
of retro computer equipment. Originally starting
with Amiga's his collection has grown to
emmense proportions and currently includes
Spectrums, Amstrads, MSX's and loads of other
stuff (including books & manuals).
His website is:
http://www.commodore-amiga-retro.com
As to why he isn't on this list himself?
I can't answer that. He is aware of this list
and of the site. Perhaps it's because he gets
too many emails from other lists/groups.
I do know he sometimes works long hours and
such.
Personally I myself can only deal with 100-200
emails a day. Any more than that and old mail
gets left until I have got my email account
down enough to rediscover old unread mail.
He certainly isn't a bad person at all, he has
helped me out in the past with amiga software
and (colour) photocopying magazine pages
for me.
He does dislike Microsoft and Windows though..
especially modern Windows OS's which are
constantly updating and sending unknown info
via the web. However, that's getting off-topic.

Hi,
Someone I know just got his hands on a
Compaq Portable III. Read the 3 emails below,
which are in order.
Anyone got any ideas what might have gone?

Hi
Now here is the thing... It gave out a massive
electronic bang when I switched it on.
Something definitely blew..
But it wasn`t the main computer, cus up
popped the orange screen with IBM on it, the
hard drive is working, the floppy drive is
working as is the keyboard... I can even run
the programs on it.. The crack came from by
the switch.. Slight burning smell, but gone now.
And is working fine. This baby has travelled a
long way these two days... I guess not very
happy. I can`t get over the build quality....

Nancy Hackett's bad experience:
Oh, did this machine have problems! I went
through four of those nifty plasma monitors,
several hard drives, two factory rebuilds, and
an uncounted number of motherboards trying
to track down internal error codes that
Compaq said didn't exist!
It came (not so) lovingly to be known as "The
Compaq from Hell" with the motherboard
rumored to be numbered "666". Both the
maintenance manager's and the Compaq
regional rep's hands would sweat every time I
lugged it in.
The spectacular finale was when the power
supply blew, shooting blue flames 18" out the
side! LOL! That was an experience!

Not quite the flames as described...

Well spotted. The thing just flipped out. All I
get now is all the indicator lights to power
light, caps lock etc flashing at regular
intervals. Hopefully not too dificult to trace
and fix, subject to there being no replacement
parts involved.
As I say the screen was working, so too the
drives, keyboard and obviously the processor
and memory so I am thinking something to do
with the power supply.. I had feared the
worst... And did switch it off. But I did just
check and she fired up but then just
stopped... Never mind.
