19" Rack History

by RodSmallwood＠mail.ediconsulting.co.uk

Hi I worked on British (Strowger Type) automatic telephone exchanges in the 1960's. The guy I worked for (then 60+) told me they first made racks 19" to hold a given number of standard relays in a row.

I'll have to check one or two of my old electronics books, but my guess is that the size originiated in the 1920's. Cheers, Chuck

LA50 alignment problems

by fireflyst＠earthlink.net

Okay, I'm hoping someone who knows a little more about dot matrix printers than I can shed some light on this issue: I have a LA50 printer that has a problem where when it prints, it shifts the text about half a character too far to the right on the left-to-right pass, and the same on the right-to-left pass. I tried adjusting the "align" trimmer, but that didn't help. Has anyone else seen this problem on an LA50, and is there a workable solution to the problem? Thanks Julian

uScope 820

by dgy＠DakotaCom.Net

Hi, Can anyone verify that this box (1976 vintage) also handles 8080's? I'm *sure* I had an 8080 "personality module" for mine but I can't seem to find it (nor the overlay or the pod). (sigh) I've got to get this mess sorted out so finding things is easier! --don

Lets play name that game; Who has a better memory than me?

by jplist＠kiwigeek.com

Answer: Darned near everyone. I'm trying to locate a game I used to play on my cousin's computer back in the early 90s. The game is most likely older than this, but I can't say how much. (The only other games on this machine was Test Drive (#1) and some horrendous ASCII golf game) The game was a top-down dungeon style game (As in the location, rather than D&D or Zork association). The game used ASCII characters to build out the 'map' that you walked through using the arrow guys to guide your character, if memory serves an *, running into monsters and treasure and the like. I -think- the dungeon view only took up a portion of the screen, perhaps the right-half only, and your view was fairly limited to a "if you were in the dungeon this would be the extent of your eye line" sort of thing. Pretty nifty. Does this sound famaliar to anyone? A name would be great, a link would be disco, and source code would be fascinating. Thanks all for your hive-mind; JP

Weird. Hmm. There is no guest account. The anonymous account should accept pretty much anything you throw at it as a password. Try again?

American Automation emulators?

by rigdonj＠cfl.rr.com

Oh, what the hell! I sent outside and dug the rest of the stuff out of the car. Here's what I have: 6800/02/08, 65xx, 8085, Z-80 and 27xx (programmer?). Looks like a nice collection of vintage stuff! I have both pods and interface cards for each of them. In fact, this stuff looks NEW! Most of it is still wrapped in foam plastic sheeting and it's VERY clean.

19" Rack History

by technobug＠comcast.net

I think the standard probably had its origins a bit further: My 1919 Westinghouse Catalogue lists control desks that have sections of 16, 20, 24, and 32" wide. The section was covered by a panel that spanned the width of the cabinet - the equipment was intended to be mounted on this panel. From the drawings it looks like the actual space within the sections would be an inch or so less - the specifications are a bit lacking. A 3'x20" rack with side panels ran $817.50!
