+R/CONSUMER ELECTRONICS SHOW?,
+Yep, the final (fourth) day of CES--Sunday, 6 June--is open to the public
+this year. If you need further details (or would like to visit during the
+MUCH-less-crowded trade-only days (3-5 June), give me a call. I can be
+reached at (312) 939-3300 most weekday afternoons. Unfortunately, I am
+lucky to call to the few local BBSes I still follow more than once per
+month, so I probably won't see a reply here till after the 6th <smile>.

+MICROCOM DIP SWITCHES,
+I picked a microcom ZX/2400 external modem and need an outline of
+both dipswitch functions,anyone have this or Microcom's address?

+R/AN INNOVATION...?,
+Another possibility is that when you had two outputs connected together,
+one of them was able to sink enough current from the other to alter
+internal thresholds in the driver/receiver chip (assuming it was one
+chip with both, rather than the old 1488 and 1489).  Maybe the chip
+was sourcing enough current into its ground to alter the reference
+points (similar to a TTL counter double-counting because the first
+count created a current spike).

+R/1ST BBS QUESTIONS,
+  <Cont'd>
+  1. Who am I and what do I do?  Well, I started working for IBM in '68,
+and was bitterly disappointed to find the sales offices didn't HAVE
+computers!  So I got interested in having my own - early '70s all that was
+available of course was minis.	In '74 I heard of micros, and "TTL" chips
+for the first time, and spent the summer teaching myself digital electronics.
+I built my own selectric typewriter terminal interface, and also an intf.
+for a floppy drive, in '75.  Thus when the IBM 8" diskette became standard
+years later, I was incompatible due to having gotten in before standards
+came about.  SO, I needed a way to share my then-prolific programming
+talents, and get other people's programs, and cassettes weren't "cool".
+SO, based purely on an ascii ref card that showed words like "ACK", "EOT",
+I wrote a program - and indirectly I guess - designed a protocol.  I tried
+to get Heath (now Zenith) to come out with a home computer kit in '74, but
+they didn't have "the vision", and said "oh, we HAVE a computer - it is
+analog".  Similar results from asking IBM to come out with a micro - they
+said "We don't see a market for such a device" - in '78 or so.
+  I graduated from Milton College with a BA in Physics and Chemistry.
+  2. Where'd the BBS idea come from?  Well, Hayes had invented the modem
+that you could answer the phone with, (I mean "at hobbyist prices" - there
+were commercial auto-answer modems, too).  Micros (they weren't called
+PCs yet) were cheap enough to afford to have a 2nd one.
+  At our club meetings, we had a cork board and push-pin bulletin board,
+with 3x5 cards with things like "Need ride to next meeting", "Lets get
+together for a group-purchase of memory chips", "anyone else have a KIM-1?",
+etc.  SO, I came up with the idea of "Computerizing" that - making a
+"Computerized Bulletin Board System" - CBBS was born.  We publicized it
+in the local computer club newsletter, I told folks on Arpanet about it,
+and I wrote an article for the November '78 BYTE magazine.
+  Hope this does it!

+R/1ST BBS QUESTIONS,
+Wow! Thanks much for your reply.  I should have known that you of all people
+would have verbose fingers...  As it turns out, the space for the article
+was cut down, so the section on the history of BBSs was only allowed one
+paragraph... so you got stuck in there somewhere between the pony express and
+the internet...  I hope to be able to do a more comphrensive story on BBSs
+for an upcoming issue (assuming that the mag survives that long).  The mag
+will have a booth at the PC Expo in Chicago, perhaps you would be stopping by
+the booth -- Computer REGISTER.
+
+Thanks for the reply, I'll hang onto it as valuable material.

+R/XMODEM CRC CALCULATION,
+Sorry, no, CRC wasn't my doing, I don't have code.  I DO believe a table-
+driven CRC in "C" is on one of the low message #'s of the "Ward Board CBBS"
+at (708) 849-1132 (2400 baud) - check msg #'s like 4-5-6-7-8 sort of thing
+- you can do "s" then "1" then ^K out and try to retrieve the appropriate ones.
