Hello!
Joe, what's going to happen to them when they become redundant, as the
English would put it?

This is simple. If the backplane has 2 slots per row then it is a QBUS
(/2 variant). If it has 4 slots per row then it is also QBUS but could
be either 18-bit or 22-bit - the part number on the side of the
backplane will tell you for sure. If the backplane has 6 slots per row
then it is UNIBUS.
In the wild this seems to be true, but the DDV11B (a hex-high Q-bus
backplane) existed at least in the minds of the handbook authors
(see p. 159 of Microcomputer Interfaces Handbook 1980).

Hello!
John W, do you recall what sort of wire wrapping board you sent me? I
keep thinking its a typical Q Bus one, but is it?

Yes, It's bearable on iPhone 4 only because of the hi res screen. The keyboard thing is still a pain though, unless you use a Bluetooth keyboard and that's a little object-defeating!

Hello!
Mark can you provide a pointer to this HP Microserver?
And go ahead and roll on the floor laughing, but I've been tempted to
track down a PDP-11, when I first saw and actually wanted a PDP-8 to
work with. My >father convinced me that doing so would be problematic
because the poor thing had only 8K of core based memory.
Is our friend behind the E11 subscribed here? He'll know what style of
wire wrapping based board I have here. It's designed for the PDP-11, I
think it >>might be the Q-Bus style one....

Oh don't get me wrong, it's cool that you can do it and I have used it a few times. For basic terminal stuff its great. I have my HP Microserver set up to allow SSH from external IPs via myy firewall so I can SSH there then Telnet into my SimH VAX from my phone :D
On the same count however, a lot of DEC text based apps like EVE and Notes (I think?) Use mimetic pad and F-key functions which are a struggle on phone-based clients.

I'm not trying to be a smart-arse but Google for 'HP Proliant Microserver'.
They rock, low cost, low size, low power, high expandability HP server. Quiet and cheap and designed by HP's best server guys. Really is a beautiful package.

The first DEC system I worked with was a pdp-11/40. It had a CR11, an LP11, one RK05, an RX01 and a DECtape I unit. It did have MMU but just 32 kB core, which was expanded to 64 KB core. That allowed KED to run with RT-11 (V3, V4).
I did experiment with RSX-11D but preferred RT-11. The pdp served in a laboratory, it got an LPS-11 interface later on.

OK, so we need someone to code a trigger a the notes server to post to the email list and write an email gateway that will process emails and add notes posts. Best of both worlds. Now who will step up to the plate?
Sounds like the kind of crazed idea that Sampsa gets involved in ;)
