Several people asked me about archive pages for past Vintage Computer
Festival events. Much of the information was lost during a rebuild of
the former Festival owner's web site, however, much of the same
information was also available at Archive.org. Tonight we posted about
50% of the basic date from past Festivals -- when, where, who -- at
http://vcfed.org/wp/festivals/archives-show-summaries/. (It would be a
HUGE amount of work to post the exact web sites from past Festivals, and
there's not much point to saving the logistical information about what
time of day people will speak, etc., so what we are posting seems like a
good balance.) We hope to get the remaining 50% onto the page soon. PS.
You'll notice that the page is being populated from the bottom-up. No
particular reason why.

Hey folks,
I've gotten to the part of a PDP-11/45 restore I?ve been working on where I need to run a Unibus cable between the CPU box in one rack and an RK11-C controller at the top of the next rack over. I'm a bit puzzled about how best to run the bus cable to keep it out of harm's way, e.g. getting it accidentally pinched or crimped while sliding the CPU cabinet in and out for service.
I can see there's a nice cable exit at the back of the sliding CPU cabinet, but from there...?? Anybody have a picture or remember how this was usually done around the slide rails etc. to avoid trouble?
The RK05 manuals do have recommended dress for drive cables between drives and the controller, but I haven't seen any recommendations for the cabling Unibus between cabinets anywhere yet.
cheers,
--FritzM.
If you're part of the AppleFritters forum you may have seen that I put it
up for sale, but if you're not and you're interested, please drive me an
email! I'm planning to put it up on eBay later tonight if nobody here is
interested :)

Guys,
I'm working on a special TU58 emulator called "tu58fs".
It saves the "tape content" not only in a binary image file, but also as
a file set in a shared directory on the host.
The content of the "tape" (as seen by the PDP) changes automatically as
files are moved in and out of the shared dir.
This works in both direction: creating/changing/deleting a file on the
"tape" modifies the files in the directory.
Today tu58fs passed the tests for standard XXDP tapes, good time to tell
the world about it.
If you like to have a look (and play beta tester):
Docs on http://retrocmp.com/tools/tu58fs
C sources and makefile on https://github.com/j-hoppe/tu58fs
tu58fs is intended to be a general tool for easy file sharing between a
PDP and the modern world. For this as much DEC filesystems as possible
should be implemented.
We need more than XXDP, but I wasn't able to find documents about the
structure of DOS-11, RT-11 or FILES-11/ODS-1.
Any links?

I posted yesterday about my attempt to weld a IBM PC keyboard to my Compaq model 1 - the 'luggable'.
Well, it did not work, even though I saw clock and data on both Compaq and IBM keyboards that looked the same. I did not dig into the decoding, but somehow they are different.
OK so I already cut into the PC keyboard, a BTC 5100. I let my son play with it and a screwdriver, and as he gets it apart, I see capacitive foam pads inside.
Well guess what, they are the same size and fit for the Compaq Keytronics keyboard!
I popped out all the pads and transplanted them, you push them in and snap the plastic disk in the guides with an exacto, and they work perfectly.
I think a lot of these early keyboards before the switch to elastomeric rubber have these foam pads, and they are a standard size.
If you are stuck with a Tandy, Lisa, Sun with keyboard foam rot, take a look in you junk bin for a IBM PC compatible keyboard, it worked for me.

I've been working on documenting the hardware in the early Altos x86 machines
and it would be nice to find a copy of the eproms from a 586.
I tried asking Dave Dunfield about this, but never got a reply. Has anyone
heard anything from him lately?
I know Eric Smith was trying to contact him a few months ago about extending
the known disk types in Imagedisk (specifically adding M2FM as one of the formats)
but I don't think he ever heard anything back.
Hi folks,
Does anyone know what this is? It's obviously a transformer coil(s) but
image search and googling those markings produces nothing:

It's taking and giving +5V but I'm sure it should also be producing another
voltage...
Cheers!

I have several books available for the cost of shipping if anyone is interested, otherwise they'll go to my local book reseller this coming weekend.? All are in pretty much like new condition.
