I do have an Electrosonic catalog (Canada) from the mid 1960s. It is
very handy as it covers things like CDS cells, Germanium items (ratings,
etc) and other odds and ends of industrial electronics where there are
no other sources of information.

Umm, that's where I got the prices; as a matter of fact I used to work
for Electrosonic in the 60s in industrial sales, still around after all
these years...

Kind folks,
I was just wondering if anyone else is able to view the 3 movies near
the bottom of http://pdp-1.computerhistory.org/pdp-1/index.php?f=theme&s=2
For me, each one runs for a bit and then just stops. Windows task
manager shows no internet activity at that point. If I bring up some
other page and then go back there, the video gets a bit further each
time before seizing up again. Perhaps if I had infinite patience I
could eventually see them all the way through. Any idea what might
cause this?
Thanks,
Charlie C.
Hi,
Does anyone have an image of an Digital Equipment Corporation van? A
friend and DEC fan wants his new white van to look as much as possible
as original DEC vans. There seems to be an image of a large number of
vans parked for a corporate building in some DEC brochure.

Hi,
I have an Intel SDK-85 System Design Kit here (single board computer)
which doesn't want to turn on. After some debugging, I'm fairly
confident it's the ROM that's dead, but I can't find an image for it on
the Internet.
If someone has a copy of the ROM image, or is willing to dump it, I
would greatly appreciate it.
Thanks,
Alexis.

Gee, I just offered a nice classic RS/6000-520 that you coulda had for free
;-)
Lots o' 40-bit memory, 32 ports, SCSI HD & tape; really hated to see it go
to the dump.

Well, just to add to the list, I have the 1969, 1973 and 1981 TTL
databooks from TI, as well as a 1965 TI component catalog listing some
TTL devices (also various from Fairchild, National and Moto).
As with others though, I haven't managed to dig up any prices.

FWIW, approx. Canadian 100-1000 prices in 1977:
Gates: .28
F-F's etc: .48
SRs, adders, etc: 1.50
16Kx1 SRAM: $113.74

Mmm, just mentioning RACAL reminds me of (what was) my RA6790/GM.
Sadly I had to sell it to pay the mortgage a couple of years ago, plus I
felt kinda guilty having such a great receiver but not having much time
to use it.
Its CPU is a Mostek F8 as I recall, at least on the earlier ones (and
mine).

Speaking of Racal, I still have a Technical Manual for a model 9521
'Computing Counter'; is there a group/forum/site out there somewhere that
would be interested (if it isn't already out there)?
