Hi, folks. I'm starting a vacation this Saturday with a few days in
Manhattan. Are there good classic computing or telecommunications
museums, or other interesting sites, there? I know IBM used to have a
museum in Manhattan, but I never got to see it -- I'd hate to miss
something else just before it closed.
Any help is appreciated, and I'll gladly take pictures and/or send
postcards for those who are interested :-)

My impression is that the devastation that was the World Trade Center
took out NYC's second-hand electronics marketplace. That is, when the
WTC was put IN, in the 70's, they took down all the buildings that housed
the radio parts sellers. As for the IBM museum, I saw its incarnation in a
Westchester warehouse in 1991, it's a Great collection, but well out of
NYC even then.
A joke, son: Maybe your best bet is to find a 3rd rate electronics store
passing off a 1981 PC as "new".
(Hard to get past that $1,100 pricetag though <g>)
Someone else?

Got given a couple of "Dyna 5" BA23-size QBUS enclosures a bit ago -
a bit tatty (rusted & dirty, must try to get a sandblaster or
something to see if they can be rescued)
just looking through the cards, can't ID this one yet :
dual height QBUS
Baydel (http://www.baydel.com) logo on the handles, "Baydel ltd" "CCK
2789" "B01079 iss4 C1984 CTS-11" on the board.
50 pin (2*25) front connector (what's the proper name for these
ribbon cable IDC connectors/plugs? Berg? other?)
1 AM2901, 2 off AM2910, 6 off AM27C291. 1 62256 (32k*8 SRAM I think),
some TTL, DEC interface & PAL DIPs, 16MHz rock.

Sand-blasting is great. I applied this to
some parts of a rusted
PDP-11/34A, repainted them, looks like new. Reminds me. I still haven't
sand-blasted the card cage...
dual height QBUS
Baydel (http://www.baydel.com) logo on the handles,
Can you put it into a KA650 /
MV III / MV 3500 or better machine and do
a
show qbus
on the ">>>" prompt?

No idea, I'm afraid, but reminds me - I used to have *two* complete Baydel
mfr'd PDP11 clone machines kicking around at the office for a time, until
my boss took them to the *tip* whilst I wasn't looking one day a couple of
years ago :-(
AFAIKR Baydel had their own versions of pretty much all the cards in the
box bar CPU.. There is a chance we may still have some docs kicking about
at the office - will try and have a hunt next time I'm in there for any
length of time.
(Stuck on site at the moment trying to sort out a massive mix of Cat 4 and
Cat 5 cabling where previous occupier of building simply cut the lot off to
remove the patch cabinets [and microvax - older sockets all have a DIGITAL
logo emblazoned on them])

Thanks Rob, Jochen, Pete for your help.
Baydel tech support emailed me back quite quickly to let me know that
the card is a "CTS-11", and was designed to replace a TS11 +
controller with a QIC drive (there was a disconnected QIC drive in
the Dyna5 chasis, but it was so corroded, dirty & yuk that it's in
the heading for the bin pile)
The chap at Baydel (Leatherhead, UK) said he'd been there for years
(25 or more) and had seen them through making whole PDP11 systems
(apart from DEC CPUs) to their current range of NAS & SCSI RAID etc
