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

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.

German collection (was Software Archaeology)

by aek＠bitsavers.org

> It's a shame that all this went to the US 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 Kelly

PSU Capacitors

by tpeters＠mixcom.com

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.

The card doesn't appear to ship with the NI analyser software, which NI is still selling at USD99. http://sine.ni.com/nips/cds/view/p/lang/en/nid/10624

Software Archaeology (was Oregon Software Pascal/2 (24 bit words))

by aek＠bitsavers.org

> As you're more aware than (probably) anyone at > this point, software archaeology is exceedingly difficult. 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.

Slightly OT: Sony Typecorder

by evan＠snarc.net

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.
