Enigma, Bombe, Colossus and all that. I need to get down there sometime and
drool over the Elliott 803.
Jeremy Clarkson dos the BBC2 Top Gear motoring program, used to be a serious
motoring program but in recent years has turned into a "boys toys lets see
what stupid thing we can do with a car" program, funny all the same, a bit
of light relief.
I'm very surprised Bletchley Park let him near those machines, the BBC must
have had to agree to serious contractual terms, Clarkson's comments are
always controversial and he is renown for breaking things, especially that
involving technology. I have to say I do agree with him sometimes.
Mike.

That's the old Block H museum at Bletchley Park and to be fair he's only
smashing up a Tecra :) That room is now the Large Machine room of the new
National Museum of Computing and we now have the entire run of H-Block
which
is the world's first purpose built computer room that housed the
codebreaking Colossus machines from Jan 1944. Jules will be along soon to

I've just had a email from Bob Doran, who was one of my CompSci
professors at Auckland University.
It seems that they (AU Comp Sci) have the front panel from my 360 which
they salvaged many years ago, and which is now becoming part of a lobby
display.
So at least now I know something about what happened to it, but I
suspect that the rest of the system was scrapped.
One part he's after for the panel is the centre Display Store Selection
rotary switch dials (there are two parts to the rotary switch), so if
anyone happens to know where there's a spare one, I'm sure he'd be
grateful!
(See the top picture at

In reading some stupid web site today that claimed to have a canonical

that AS/400 was created as a "VAX killer" by IBM.
Is this really true? I never heard of an AS/400 described that way.
They also had some weird ideas about DEC vs. IBM networking described
in that argument, as if neither company supported TCP/IP until their
proprietary networks (DECnet and SNA) were forced to relinquish ground
to open protocols.
OK, googling brings up the link. "Network World" is the culprit:

I was at I think the 1990 or 1991 New York Computer Show at Jacob
Javitts and IBM had a booth setup with a ton of the small BA440 sized
AS400's and they were streaming video across a network onto a
presentation screen from one, running Novell on another, I thought
perhaps they were running a derivative of OS/2 (but I'm not totally
certain) and then running others with standard AS/400 apps on others.
The IBM rep's were touting their abilities and DEC Vax's were mentioned
several times during the course of casual conversations I overheard
throughout the booth. They were really pushing the AS/400's as the end
all, beat all workhorse machine.

no way to make it work with Linux/Irix/Solaris/MS-DOS which was what I

The original "VAX killer" was the IBM 9370 (or so I was told
when I was working on a mixed DEC/IBM site back in the 1990s).
I've never heard an AS400 described that way either, but by then
I was firmly entrenched at DEC sites (and then DEC) so I wouldn't
have been in a position to hear such gossip anyway.
Wouldn't surprise me to hear the phrase re-used though.

Hello!
In an attempt to resurrect an old Mitsubishi MR535R (RLL) drive, I managed
to
pick up an ST11M controller by accident - it was advertised on eBay as
"MFM or
RLL".
Two things:
1) Does anyone have a spare set of control and data cables? I'm willing
to
pay for 'em, or visit Maplin for components to make up a set, since
they're
probably easy to make with IDC connectors and ribbon cable.
2) Does anyone happen to have a suitable RLL controller they're looking
to
get rid of, or could let me have access to one for a few hours? The 60Mb
drive
possibly contains some very old RM Net 3.1 software which I'd like to
archive
off, as there doesn't seem to be anyone at all - even at RM - who has any
software left. I'd be happy to travel (within reason, I'm in London, UK)
and
exchange use of a controller card for beer/alcohol :)
Cheers
Peter

There's a lot of room for shades of gray in there (what does 'forced'
mean, and
how far, and when) but I'd say there is a good deal of validity to that
argument. In the 80's DEC and IBM were pretty big on pushing their own
'networking solutions' and did their best to avoid open protocols, at
least
above the link level. TCP/IP didn't have the degree of prominence in the
networking world in those days as it does today.
There was also resistance to open protocols at the customer level if those
customers were already ensconced in the proprietary networks. A lot of
people
were looking only at their immediate needs rather than seeing the future
of an
'interconnected world'.
(As I've said before on the list) there was at least one third-party
producing
a TCP/IP stack for VMS before DEC got around to it. To my recollection,
IBM was
even later in taking up TCP/IP, although one might have to distinguish
between
mainframe and PC stuff.
Put another way, DEC and IBM didn't support TCP/IP until they 'had to' (as
in
market forces).

I don't know if IBM created the AS/400 as a VAX killer. I doubt it.
The AS/400 is a direct descendent of the S/38. The S/38 was designed
and built by the people who brought you the S/36, S/34, and earlier
machines. The IBM plant that built those machines and related equipment
has been in Rochester MN since the late 1950s.
Both series of machines competed in the mid-range market. I don't think
that IBM has 'won' the mid-range market with the AS/400 and iSeries. I
think it is just the last player standing in that market, with Unix
machines having done serious damage to all of the players.

DECnet runs over ethernet. Plan 9's IL protocol (used instead of tcp
in the early days) runs over ethernet. I think you're confusing
physical layer with protocol layer :)

Yes, ethernet was precisely what I had in mind as I added that little "at
least
above the link level" clause to my comment.
Ethernet is quite distinct from TCP/IP, it's just another link type as far
as
IP is concerned. DEC latched on to ethernet quite early to use as a
(choice of)
link layer for DECnet.
It is kind of funny that manufacturers could agree on physical & frame
level
stuff (RS232,HDLC,ethernet,etc.) but then had to go their own way in the
higher
layers.
Or one might say that agreement started at the physical level, and it just
took
time to go up the stack getting agreement along the way. (Or else it's
just
easier to be proprietary in software than hardware.)
I well remember linking VAXes together and fighting with 2-metre loops of
thick-wire ethernet while banging those damned metal brick transceivers
around,
until DEC saved us all with that first 8-port ethernet 'hub' (although the
transceiver cables were still a pain). (Am I correct in recalling it was
called
the DEQNA?).
Youngsters out there should be grateful they don't have to wire their home
machines together with thick-wire...

DEQNA = Q-bus Ethernet (M7504), replaced by DELQA (M7516) and DESQA
(M3127)
Maybe you meant DELNI = Digital Ethernet Local Network Interconnect,
which had 8 local AUI ports.

In the 80's DEC and IBM were pretty big on
pushing their own
'networking solutions' and did their best to avoid open protocols, at
least above the link level.
In Montreal, in the days before Teh Internet, each of the four
universities here was using IP internally, but had no IP connectivity
outside themselves. Then DEC, presumably trying to earn some kind of
PR brownie points in support of higher education or some such, donated
routers and leased lines to tie them together - but the routers were
DECnet-only. (I proceeded to use IP/DECnet dual-stack Ultrix machines
to turn this DECnet-only infrastructure into an IP transport...I don't
know how DEC felt about this nose-thumbing at their attempt to lock us
into their proprietary way, but the CRIM treated it as a feature, so it
would have been impolitic for DEC to grumble publicly.)

No. The DEQNA is a Q-bus Ethernet card. (I don't remember DEC's name
for their AUI hub, but I know the DEQNA.)

Aye. Thicknet was difficult to run and (at least in my exprience) the
transceiver/cable connection was horribly finicky.

Thanks for the correction. I think I've heard "DEQNA" in recent years and
it
was supplanting the memory of "DELNI", which I haven't heard in years.

DELNI?
