IIRC, 19" racks go back before WWII. I'll have to check one or two of
old electronics books, but my guess is that the size originiated in the

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?
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
(sigh) I've got to get this mess sorted out so finding

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
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.
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;

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

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.

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!
