I have a Laser Turbo XT that I'm trying to resuscitate to 100%. I have it
almost all working, but I'd be durned if I can't figure out how to get it
into turbo mode. Right now it's blazing along at 1.4Mhz if the Landmark
speed test is to be believed. There are no hardware switches so I can
only assume there is some sort of utility program that needs to be run?
If so, I don't have it :(
Any hints?
Thanks!
Happy New Year!

If I remember right (it's been many years),
turbo switching was actually performed from the keyboard.
Try hitting CONTROL ALT +? to enter turbo mode.
(Use the + sign on the 10-key)
If that doesn't work, try various control combinations,
including sequences ending with Page Up / Page Down.

I don't know right offhand where to find them, but you should dig around
and find the glyphs for the "Dali Clock". These morph from one digit to
the next.
Over a year ago I asked for some help on getting a PDP-8/e EAE
functional. There was an immediate response and I got a later version
M8330 that was EAE compatible. Thanks to those who helped.
In the spring I got a version of SPACEWAR to work. I also played with a
clock for the point plot display. I made some videos, but didn't do
anything with them at the time. I was not satisfied with the quality.
Nonetheless, today I added them to my web pages.

The clock video on the VC8 page is much more dynamic. I used some unix
font tools and a little bit of python to make bitmap images of the
numerical characters. These were then converted to PAL8 source. The
hands are drawn using the Bresenham algorithm.
Since it is the close to the new year, I want to thank everyone for the
knowledge that I have gained from listening here. When we don't stumble
over our own narrow mindedness and biases we are a pretty knowledgeable
bunch. Thanks again to all...

PS: I tried the videos using firefox and internet explorer in windows
and firefox in linux. I am curious if there are problem, but please
don't turn this into some kind of off topic discussion.
A friend has a Data I/O 2900 and has lost the disks to it. He says
he found Disk 1 of v5.7 and Disk 2 of v5.8, and Disk 3 of both sets is
missing.
Anybody able to help out with disk images?

Sounds like a one-off by or for the NCAR crew; given the date, the
standard CDC product would have been something like the IGS 274--a
large display console with light pen, but with the controller in a
separate large 3000-series type (i.e. green glass and "barred"
front) cabinet.
Certainly hooked up to the 6600's that NCAR owned at the time. Did
you check the pubs catalog in the CDC section on bitsavers? It's
pretty complete, even listing QSEs.

Hello listmembers!
Apart from the usual Season's Greetings to all of you, I've got some questions again. Sometime this year, I scored some kind of video digitizer/framegrabber card out of an old PC. These days I managed to analyze the harddisk that came with it for drivers, but didn't find any.
The board has a PCI edge connector, a BT848 video decoder (datecode from '96, so marginally on-topic), two crystals, a bunch of passives, and an s-video socket plus two RCA sockets accessible from the outside. Manufacturer is "MultiMedia Access Corporation" according to the etch, a sticker holds the part number "91-00109-01 Rev. C" and a serial number. www.MMAC.com now redirects to the site of ViewCast and the oldest stuff I was able to find there and in the waybackmachine are drivers for a series of cards called "Osprey". Anybody got some hints for what I've got there and where to find drivers/software for it?
Additionally, can somebody please enlighten me as to the pinout of that weird 7-pin Mini-DIN video input connector on the WinTV PCI series cards? I know that the outer four pins will accept a standard s-video cable, but I don't have the adaptor plug needed for composite input and would like to cobble up a replacement.
Thanks in Advance, and my best wishes for a successful year 2008.
Yours sincerely,
Arno Kletzander.

Yep. Would have shipped with a Type-3, but you can do a cable adaptor

analog.
I believe that after a while the serial console will pop out with a
">", but there are no intermediate messages such as you get with a
SPARC. Haven't had one of these for a couple years, but I remember
getting the console prompt on serial when I had one
I have a DD-50 single drive enclosure and a surfeit of DD-50 -> HD-50
(SCSI-II type) cables, as well as some Type-4 keyboards in my garage. I
haven't gotten the original message yet, so I'm not sure where you are
- I'm in the Western Washington (state) area.
The 3/60 is eminently hackable - look at the Sun-3 Zoo for ideas.
People have wired in internal 1/3 ht drives (there are solder pads for
a 50-pin header on the SCSI bus) and done many other things. I run my
3/110 diskless from the network (served from an IPX, but Suns are so
standard that you should be able to use Linux or xBSD). 4.1.1_U1 is the
release of SunOS to get, and it's floating around out there.
Hi there,
I work with Andrew Back, and he's recently forwarded us a copy of your email
about the old computers you're about to throw away. We'd very much like to
give them a loving home - specifically the CMB Pet and BBC Micro computers.
Are they still up for grabs? If you could please let me know availability
and location, I'll sort out a courier or something similar.
Many thanks for this opportunity!
Cheers,
Phil
If you feel this subject is too far off-topic, please respond
privately. OTOH, it just might help some who are trying to repair
some of the old gear that uses SMT.
At any rate, I've got some 68-pin TQFP packages that I need to mount
on a PCB. I've searched the web and become throughly confused over
recommendations.
I'd like to stay away from using a hot-air rework iron as I don't
think I have enough skill to use it without causing some damage to
the PCB or component. I'd like to use my temperature-controlled
Weller soldering station as the heat source. I'll also be using Sn-
Pb solder rather than lead-free.
Two approaches that I've seen for conventional soldering iron
mounting involve what I'll call "flood and suck" that involves
covering all of the leads on one side of the QFP on the PCB with
solder and then using a solder "sucker" (such as a Soldapullt) to
remove the excess.
The other approach uses solder wick (solder removal braid), laying
the braid over the QFP leads and PCB and heating and applying solder
*through* the braid to the leads.
I'm fairly confident that I could do either, but who's had real
success with either method?
Thanks,
Chuck
