It?s Droste Week on RetroBattlestations! Inspired by a couple of different posts, I thought it would be fun to do a challenge where people don?t just post a picture of their computer, but they display the picture of their computer *on* their computer and post that! It?s going quite well and I really enjoy reading about the hoops people are having to jump through to get pictures converted and transferred and displayed.
There have been photos of monochrome computers with high resolution, low resolution block graphics, ASCII art on CP/M computers, and even a mechanical typewriter! What can you come up with?

Oh butts I sent that before I proofread.
I'm in the Pacific Northwest, about three or four hours east of Vancouver
BC. I have access to freight services should you take that route but for
your wallet I'd strongly recommend some sort of local or negotiated pickup.

That bloody EDAC connector is not cheap. I ended up sourcing one for like
$60. On the other hand you can hunt around for scrap 50 conductor telco
cable and you're all set for cabling. You can usually get it for its weight
in copper from a scrapyard.

When repairing machines it is some times hard to find the data sheet for a
particular component.
Sometimes google hasn't been able to find the the data sheet for me.
My father worked in the electronics business for his entire career and kept
a lot of the data books that he received.
I have compiled a list of them, mostly for my self, so that I somewhat
easier would find what I look for.
I publish it here. If you have searched everywhere (bitsavers , google
etc) and not got a decent hit and think that one of the data books in my
fathers archive would help I might be able to assist. No - I am not going
to scan entire books. But a few pages is OK. The latency might be high
since the archive is located 100 km away.
https://docs.google.com/spreadsheets/d/1fTfBDLxl40e2iNrbwLv1ZGgIaXvz_toyvfc…
I will add more to the list as time passes. There are quite a big bunch of
data books left to do an inventory on.

Good Morning All Panel Fans!!
According to the shippers the first consignments of PDP-8/e front panels
were delivered in the US yesterday,
Confirmations and comments to me please.

ok the m 200 and 600? tend to have gooey rollers... thus the reason
I ask...

Mike where did you get new rubber roller things for the card
reader?

There's also Brian Knittel's USB interface for the Documation readers:

I built one, and it works well.

I think Tony's point was that someone who's into vintage computers ought to
have a stock of suitable parts for them.
So unless he's into older guns, or cars, were he not to have things like SAE
8 hardware around, that would be understandable - he doesn't do them.
Having said that, _I_ don't have 2N3904s nor NE555s around either! I do have
a modest number of parts (e.g. 4164's, 40-ping Berg shells, .250 tab
hardware, etc, etc) - a large enough collection that I just had to
re-organize and add more parts holders (although that was mostly because I
went berserk at the local Radio Shack in the 80% off sale). But it takes a
long time to build up a really comprehensive collection of parts.
It's funny, I was thinking of this exact topic last night - wondering if I
could find someone who's selling off a large cabinet full of mixed spares! (I
was thinking of the experience of one list member, who lucked into such.) I
could certainly use it!

> How was alignment packs produced?
On a special rig, I'm pretty sure. I don't know how the RK06 alignment pack
works, but I am familiar with the RK05 (our machine had them, and we had to
realign one after a head crash), and I assume it's probably similar; it had to
have been created on a special rig (the exact nature of which I don't know,
but I know a normal drive couldn't write it).
For the RK05, the alignment pack has alignment tracks with alternating
sectors written a couple of thousandths of an inch offset from the track's
nominal center line; when one watches the head's output on a 'scope (at a
timebase sufficient to show pairs of sectors), if the output for both sectors
in a pair is at the same amplitude, the head is correctly aligned. If not,
it's easy to see on the 'scope - one has higher output than the other.

I know I keep pushing the boundary of vintage lately but I wanted to report
to those who care that I finally got my hands on a 1993 Compaq 5/60M - this
is "a if not the" first desktop computer with a Pentium processor installed
stock. it was the 1993 "dream machine - $9000+ It had an EISA bus and
was otherwise a 486 system with a Pentium controller card, not on the
motherboard. Pentium computers' contribution to the WWW era vintage is
extremely significant.
Pentium killed the minicomputer, or at a minimum merged into it, if you ask
me. The interplay between DEC/Compaq/HP/Intel 1992-1995 culminating into
the launch of Pentium processor systems is vital to understanding the WWW
era of computing. How these companies worked or did not work together and
how the Pentium vs. the Alpha processor came to be...a good tale of woe and
$$.
For those interested: Compaq 5/60:

I have a bunch of articles to post on my site related to the first Pentium
desktops which I will do asap.

P.S. while we're on this off-sh topic I also posted some photos of a
Digital 486 laptop, DEC had a 486 laptop before it was absorbed by Compaq.
1994. Not really noteworthy other than the Digital name

P.S.S. and related to Pentium and DEC ... here is one of DEC's early (but
not the first) Pentium machine
