Hi Jim,
What a coincidence -- we just got a lengthy email from Wayne Farmer
in the ibm1130.org guestbook, who also talked about working with
the that same Meta IV (production serial #1 in fact), at UC San
Diego, and he described working with these very microcode ROMs.
Hey, are you planning on coming to the Vintage Computer Festival
in Mountain View, CA in November? If you are it would be great
if you could bring this microcode board with you to show off
at the IBM 1130 party which will be held Saturday evening during
the VCF.
Brian

Re: "I guess this all means that RS232C has fallen into the category of
"obsolescent technology"."
Some brand new JVC DLP 1080P TV sets have a control interface (this is only
present in some of the newest, highest end models) that allows the TV to be
controlled by {presumably} a media center PC. It's RS-232. These TV sets
were only introduced this spring. Why it's not USB is beyond me, but it's
not.

about. Plug forward!

Not all of this has gone to the US. If there is a single coordinated effort
there to save the remaining material, that would be great. I would suggest
coordinating this with Doron. There are a number of GA and DEC minis, a
System3 and System7 for example that need to be saved.
> Will I be able to get copies of all the software and/or documentation?
Do you have any idea of how much 1 1/2 shipping containers worth of docs and
software is?
I will try to make as much material as I can available, as I have been with
other things in the CHM collection, but this may literally take years to do.
I'm actually starting the archiving of the more than 1,500 8" disks that I have. Here are my intended methods. If anyone has any comments, please speak up.
The ultimate goal is an online searchable database of these disks.
1) number each diskette sequentially with date
2) taking a digital picture of the label
3) Making a catweasel image of the contents
4) Makine an ImageDisk image of the contents
5) Storing the following information in a database
Diskette number
Any text from the label
System if known
OS used if known
Date of origin if known
Description of contents
if commercial software, the publisher/author
Photo of the label
Both disk images

Look for a swap (amateur radio) otherwise know as a hamfest. They have them
all over the place at various times of the year. I usually see big caps
that look relatively new for a decent price.
This might help you locate a swap in your area:

The thing to do is just keep asking anyone who was connected to the industry
if they know folks like field serivce techs that were pack rats. The
companies themselves either deliberately threw it out so that they wouldn't
have to support it, or the physical assets were tossed out when companies
were sold.
The fact that the SDS 900 series library survived mostly in tact after being
given away by Honeywell in 1982 gives me hope that people may have similar
stashes somewhere.

Somewhat related, a CHM press release just went out with this info in it:
In support of its international collection and exhibit plans, the Museum
also announced that it has acquired an extensive collection totaling seven
shipping containers of computing objects salvaged from a crumbling warehouse
in Dortmund, Germany this month. The rescued items, along with related
documents and software, will augment the Museum?s existing 80,000-object
collection that will be used to populate the 2009 exhibit.
The historic collection from Germany was rescued from an open-air warehouse
that encompassed a physical area of about 12,000 square feet. There are 112
unique manufacturers represented, including Telefunken, Siemens, Zuse,
Olivetti and Groupe Bull. European-based manufacturers account for 50% of
the acquired artifacts and another 20% in documentation and software. In
addition to many rare computer systems, the rescued items will deepen the
Museum?s holdings of electromechanical-era objects, as well as mainframe
documentation and software.

The container with documentation and software should be getting here in
about a month. From the pictures, there are some very interesting things
coming. This was partly from the computer museum which closed in Achen.
Anybody have one of these? It's an electronic word processor from 1980. It
looks similar to the Epson HX-20 (microcassette drive, same "slate" form
factor, etc.), but it's just a WP, not a full computer.
