I suppose someone here might know this! I've an external Sun case that
accepts a single 5.25" SCSI device such as a CDROM or DAT drive (the
case is open at the front).
It's one of those two-colour plastic shelled ones, pale blue / cream,
with 68 pin SCSI connectors on the back and a 50 pin connector
internally + power cable.
*nowhere* on it does it seem to say what capacity load it'll drive
though. Most unhelpful. Anyone happen to know?
It'd be a useful way of temporarily hooking up old 50 pin SCSI devices
to my modern PC for backup purposes as it lives on top of my desk, but I
rather suspect the PSU might go into meltdown if hooked up to a 5.25" FH
drive (with the top of the Sun case removed of course :)
ta!

What was the fastest Pentium Pro CPU produced? On one site that a
Jeeves search turned up, there was mention of the Pro getting up to
300MHz, yet another search result says that the fastest is 200MHz.
Plus, the HP Vectra XA that I am tinkering with uses a Pentium Pro CPU
(she currently has a 200), and according to the geeksheet for this
motherboard (http://www.embeddedlogic.com/TH99/m/E-H/35391.htm) this
board can take up to a 266.
So, which is it?
It's got to be 10 years old now, right?
gopherspace was wonderful, a brilliant use of the internet
besides email. Too bad for gopher that http was better.
I long ago took down my gopher server, and it seems it's largely
disappeared from the net, even wiretap.spies.com appears empty
in my browser (firefox) which tries to render it as html!
Besides a few flat-earthers ("Bring Back Gopher!") it's largely
disappeared.
Anyone on this list still run one? What's the best client to use?
Here's a good quick ref on it:

Please email Alexis directly if you want this item as I do not have any knowledge about it. Thanks

Anyone know what a 74ACT2155 IC is? Memory of some sort, but is there
anything special about them?
I've managed to pull the NCR Tower into the middle of the garage and
have pulled the covers off - I'll take the disks out later and see if
they spin up first as the machine's somewhat useless if they don't!
After that I'll reseat the boards, check the PSU etc. but I do remember
the machine had developed some sort of fault when I parked it up years
ago. ISTR it being *totally* dead, so there's likely a PSU problem.
Anyway, there are quite a few of these 74ACT2155 chips on little modules
on the system board; one of the modules is labelled as being cache so
they're definitely memory of some flavour - I've just not come across
these with a 74xxx part number before.
NCR didn't half like their PAL chips. I counted over 40 on the system
board alone. There's almost as many as there are typical logic ICs.
cheers

Does anyone have codes - Pantone numbers, or something like that - or
commercial paint names, for the following shades of DEC paint:
pdp-15 'powder blue'
pdp-10 dark blue
pdp-12 green
The light, very slightly creamy, grey paint used for front panel frames,
RA8x disk drives, etc.
Have some restoration to do!
Thanks - please CC any replies to my email, list digest distribution seems
slow of late!

Picked up a nice 1650B logic analyzer, but no manuals. Before I debate
about spending $100.00 for a set of manuals, I thought I'd see if
someone has a 1650A/B manual around, or has copies.

Hello,
I am not a programmer, but my husband is.
He has 4 each 7" tapes and 2 each 11" tapes that I believe came from a old
PDP11
On these tapes are stories that my husband wrote 15 to 18 years ago. His
son, along with his fiancee and 7 of his best friends were killed in a
tragic airplane accident in 2001. On one of the tapes is a story that he
wrote.
I thought if I could somehow download or get a copy in print form what is on
the tapes it would be a wonderful gift to my husband.
Please let me know if you can direct me where I might find someone to help
me.
Thank you,
Sincerely,
Hi All,
I'm in the process of powering up a 2113B. I took a look at the output
voltages from the PSU and they all look fine *except* the -2 volt line that
appears to be running at -2.47 volts.
I have the 2109B / 2113B installation and service manual but the service
procedure just talks about adjusting the 5 volt line and all the other
supply voltages tracking this one.
I can't find a schematic for the power supply in the documentation that I
have 02109-90015.
Questions:
1. Is my copy of 02109-9005 (Installation and service manual) incomplete
i.e. should there be a schematic in it?
2. Does anyone have a schematic for the 2019B / 2113B computer power supply.
Note that the 'B' is important as the power supply was revised between the
'A' and 'B' models.
3. What is the -2 volt line used for?
4. Does it matter that the -2 volt line is outside specification?
5. Is a full schematic available for the 2113B computer? - I'm sort of
interested in what exactly is going on on the motherboard.
Many thanks
Peter Brown
Is there a schematic online for the DEC PDP-11 maintenance tool KM11?
Googling, the best I found was a description by Tony Duell for a
homebrew replacement. Excellent as that is, a schematic is just so much
easier to read.
