Holy smokes! You're right! They're not in the 1998 catalog, but I found them in the 1996 catalog: HP-547A Current Tracer-- $975 ! I first saw these over 15 years ago-- the prices were *much* lower then! Ahhh, it looks like they don't make 'em no more. Bummer. But that was at most, two years ago. Not bad.

How to identify comm hardware you pass up

by dastar＠ncal.verio.com

Hey, here's a tip. If you're interested in knowing to what use you can put that communications hardware you keep passing up at your preferred source for classic computers, get yourself a Glasgal Communications catalog. The older the better. Glasgal was a company that sold thousands of communications products, from cables & connectors to muxes & switches, and everything in between (and I'm talking everything). The catalog I have from them is 1987, and has some pretty interesting stuff in it, including things I've seen at thrift stores or surplus shops, or things I've worked with. This particular catalog is called "System/Configuration Guide and Product Listing". So not only does it describe their complete product line but it also goes into technical discussions about certain products and their applications, including diagrams. Its basically a tutorial on how to hook up and use the products they are selling. It is very thorough and extraordinarily useful if you'd like to start building your own communcations network between disparate computer storage sites with old comm hardware. I found this particular catalog in a thrift store. Alas (homage to Tony :), Glasgal doesn't seem to be around anymore. I just made a bunch of calls, first to the number in the catalog, then to toll-free directory assistance, then to directory assistance in New Jersey, with no success. I then did a web search on "Glasgal Communications" and found this on a stock market discussion BBS: "WE ARE MANUFACTURERS OF HIGH QUALITY EMPTY GLASS BOTTLES. WE PRODUCE BOTTLES IN TWO COLORS AMBER & WHITE. WE ARE SUPPLYING TO THE LIQUOR, PHARMACEUTICAL, FOOD BEVERAGES AND COSMETICS INDUSTRIES ALL OVER THE WORLD." So either Glasgal Communications has radically altered its business plan or some new company has commandeered their name. If you run across a Glasgal Communications catalog from days gone by, grab it. This also applies to old Black Box catalogs (whom still exist) because if their old catalogs have the same format of their current catalogs, you can expect the same type of helpful information.

A 7236 is a 4 1/2 digit counter with a vacuum fluorescent driver like the 7235. Interesting that they have a common eval. board, my old Intersil cat. just says an evaluation kit is available for each one (separate numbers). -Dave

Hayes Bankruptcy

by rcini＠email.msn.com

This is the *second* bankruptcy for Hayes in 5 years. The last was in 1994 (emergence in 1996, I think). Maybe it's time to let someone else take a shot at running the company?

I think this attitude in general carelessly disregards an amazing body of work. In fact, I think people do care. I'm not so quick to sweep historical facts underneath the carpet simply as a matter of convenience. I'd rather know the complete and true story, and not just the easiest one to remember. Furthermore, you are are discounting the AMI microprocessors of the early 70s, which Holt went on to design after the F14 CADC, and the influence those chips may have had on later designs. In fact, you are choosing to go along with the popular history written years ago by a biased reporter that is perpetuated by lazy historians who simply regurgitate the information they read in the last book rather than doing real research and finding out there was more to the story, and that there is history before the popular history. The picture is bigger than the canvas it was painted on. I want to know what was beyond the frame. I'm surprised you have this attitude when on the one hand you'd like to see the HP9830 recognized as the first personal computer, rather than the Altair 8800. By your own reasoning, the HP9830 wasn't the big bang, so who cares?

Internet Question

by allisonp＠world.std.com

< Does anyone remember the cost of internet access/online time via Compuse < in the 80s ? I need to give a comparison of today's cost of sending a < graphics file. 1984 300 baud was 12.50hr connect time. 1986 1200baud was 12.50hr 1991 1200baud was 9.50hr 1994 2400 6.00hr I may be off some, it's a memory test. Compared to now, very expensive and graphic files were rarely sent before 86ish though there were up/downloads. Oh, internet mail was 1990 and roughly $0.15 a page additional I don't think sending binaries were possible then. Allison

The Kyocera KC-85 is well known, although not too common. The case is shaped more like the NEC, but it has the keyboard of the m100. P.S., come to VCF 3.0 and see all the variations (hopefully!) and check out the talk I'm going to do (hopefully!) on the history of all these machines.
