We were quite certain our Datakit X.25 network was on the Internet
(late-80s/early-90s AT&T). Email/Netnews/File transfer all worked,
though the addressing gyrations that were occasionally required were
fairly demented.
When we did NSFnet at Gatech, there was always some tweak to take into
account some "Internet" peer someone desperately needed to talk to
that was really a gateway into some baroque non-IP network. It was a
more diverse time, with BITNET, DECNet & other OSI-ish protos, and
SNA/APPN common. I became quite adept at sendmail ".cf" files. Good
times.

You apparently ran on a very different early Internet than I did.

I think the 11/40 uses that same blank, too (with less holes than the other
ones, as it doesn't have the two rotary switches); dunno about the location of
the power switch, someone who has an 11/40 will have to send you measurements.
> given a scan and measurements .. I can have a go at most types of panel.
The ones I personally would like (after the 11/45 :-) are the indicator panels
for the RF11, RK11-C and RP11. Guy will be using the RF11 panels too, not sure
if he has started on producing them yet.
> Now we need a ... switches source
Let me see if the C+K ones I have ordered fit. If so, if I buy a large group
directly from C+K, we might be able to get the price down to something
reasonable, which would save us the hassle of two different kinds of
toggles/actuators (one for the original panels, one for reproductions).

Hi all --
I acquired a Symbolics 3640 today and it came equipped with two "large"
capacity Maxtor MFM drives (an XT-1140 and an XT-2190). The 1140 spins
up fine and we were able to image it using Dave Gesswein's MFM emulator
(yay).
The 2190 does not, and it fails in precisely the same way I've
personally seen three or four other Maxtor drives of the same era fail:
It spins up fine, but when it goes to load the heads, it sounds like the
voice coil positioner for the heads is "screaming" -- it emits a
high-pitched, quite loud whine/buzz which persists until you power the
drive down. The drive is unresponsive during this time.
I'm fairly sure it's not a head crash or anything like that; having gone
through this a year or so ago with a similar drive that was scratch
anyway, I opened it up and verified that the heads weren't stuck, and I
see no evidence of a head crash after disassembly.
Further, the fault does not appear to be on the logic board -- we
swapped in a board from a working 2190 tonight and afterwards the drive
exhibited the same symptoms.
I've had this happen to other 2190s and 1140s and a few of the ESDI
drives in the same family, some of which were working in my possession
for weeks before failing -- has anyone else seen this? Any ideas? I'd
kind of like to recover the data off of the 2190 from the 3640... drat.
Thanks,
Josh
Anyone have any ideas? If not I guess the UK card is cheap enough to take a
chance anyway.

Subject: Olivetti M24 Bus Converter Card
I have an M24 which does not have the bus converter card P1050). There are a
couple of these cards on ebay in the USA, which makes it expensive for me,
and I am not sure which of the two would be best anyway.
There is another bus converter available in the UK, but it is PC1076 (IF
622), which my web searches suggest make it for the M280 (which was a 286
machine).
Does anyone have any idea if this latter card might work in my M24? It
certainly looks to be physically compatible.

AOL was a good model for general consumers. also remember many
people used AOL before the www was all the rage so... you stay with
something you have alreay learned.and AOL was accessible anywhere in the world
for the most part whereas podunk mom and pop ISPs had local phone
numbers. This was important if I was say going to UK or France for more
than a few days as dialing back to a podunk in phoenix would not only
be damn expensive but the quality of connection thru the long distance
would no doubt be horrible...
Aside from our AOL account we had a podunk that had two brothers
that seemed as stupid as Daryl and his other brother Daryl in the Bob Newhart
show that ran it. Eccch!
The game changer for local residents though was the cable companies
and telecoms offering Internet service... same bill as their telephone or
cable tv easy to sign up... and remember at first the hi speed
connects were though the telco for us and we had AOL but after I
quit travels just had a minimal AOL account... why? lots of people I
have known for eons can still contact me there.
Why do I still use it? because my friends know to reach me there.
Why will I always have an aol account forever? well until all my friends
pass on or I pass on it is a connection medium!

Uptime seemed to be better on also than some of the podunks

Some of their early efforts to COMPETE AGAINST the internet helped
establish outfits like Netcom, and were a boost to ISPs.
Perhaps Ed (still using AOL) would have some insight into what caused
their decline.

Just stick one to the back of a small LCD screen and I'm in business.
But on closer inspection the site shows "out of stock". I'll email;
maybe they'll do another batch. Or does anyone know someone who has
stock?
And I'm still left with the need for something for 3270...
Useful thread though; all kinds of interesting things coming out of
the woodwork :-)

Hi,
I have an Sun E450 with 4 cpus installed that ran fine for a few years
as a Solaris 10 box with ZFS boot. About 4 years ago I mothballed it and
pulled the two boot drives out to store (ZFS was in a mirror configuration).
This weekend I decided to see if it would come up again.
Predictably, the NVRAM is dead. "The IDPROM contents are invalid"
And it's forgotten its mfg-options. (I found info by Googling that this
should be set to 49 for E450.) I'll have to do something about that.
More surprising to me than the NVRAM failure though was that it produces
the same result when I try to boot from either drive:
ok boot disk
Boot device: /pci at 1f,4000/scsi at 3/disk at 0,0 File and args:
Bad magic number in disk label
Can't open disk label package
Can't open boot device
It seems unlikely to me that both disks have died. Does anyone have any
other ideas? Could it be related to the NVRAM failure?
Here's what I haven't tried yet:
- I haven't checked disk jumpers
- I haven't tried to mount the disks and check them on another machine.
This could be a bit of work, but I can get around to it.
It's a long time since I set up this Solaris/ZFS install. Maybe I've
forgotten some quirk of booting ZFS on old SPARC. Any suggestions welcome.
