It was a RS232-programmable clock the size and appearance of a Hayes modem (well, two stacked on top of each other) that was around in the early-to-mid 80's. I always wanted one to go with my Hayes modem, but could never afford one (heck, I worked all summer for the modem). Well, I was in a Used PC store the other day and on the junk table there was my Hayes Chronograph. No power supply, marked "modem" and priced at $5. The staff had no idea what it was, and could not imagine I would buy it. So now I have one. Does anyone out there have the programming information so I can set the time and date? -Chris ###### From: cjt&trefoil Newsgroups: alt.folklore.computers Subject: Re: Hayes Chronograph Date: Tue, 25 May 1999 16:08:50 -0500 Organization: Prodigy Communications Corp Lines: 58 Message-ID: <374B1162.7098@prodigy.net> References: <374A4DF6.2572690E@xmission.com> Reply-To: cheljuba@prodigy.net NNTP-Posting-Host: austb103-13.splitrock.net Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit X-Trace: newssvr04-int.news.prodigy.com 927666583 2709921 209.253.18.61 (25 May 1999 21:09:43 GMT) X-Complaints-To: abuse@prodigy.net NNTP-Posting-Date: 25 May 1999 21:09:43 GMT To: Christopher Strong X-Mailer: Mozilla 3.04 (Win95; U) Path: chonsp.franklin.ch!pfaff.ethz.ch!news-zh.switch.ch!news-ge.switch.ch!news.maxwell.syr.edu!howland.erols.net!portc02.blue.aol.com!newscon02!prodigy.com!not-for-mail Christopher Strong wrote: > > Does anyone out there remember the Hayes Chronograph? > > It was a RS232-programmable clock the size and appearance of a Hayes modem > (well, two stacked > on top of each other) that was around in the early-to-mid 80's. > > I always wanted one to go with my Hayes modem, but could never afford one > (heck, I worked all summer for the modem). > > Well, I was in a Used PC store the other day and on the junk table there was my > Hayes Chronograph.

If so, does it have any conception of century or does it just keep cycling from 00 to 99 then back to 00 again in the year field. And does it check for leap years and only permit them when the year is divisible by 4 or use the full algorithm? Might seem like a stupid question for an old device like that ... but then again my Rainbow running CP/M V2 is Y2K and Y2.1K, 2.2K, etc. OK and Unix's calendar program goes to 9999 (even though 1970's PDP-11 Unix (e.g. V5) has a Year 1999 (date becomes gibberish in late November) problem and newer Unices a Year 2038 or thereabouts problem) -- so there were *some* programmers in the '70's and thereabouts who didn't cut corners with dates. I think the listing of those Hayes commands is interesting from a historical perspective as well. Today the Hayes modem commands are standard and virtually universal, but apparently when Hayes invented them, its language was one of several dialects, and this chronograph uses a different dialect that has almost been forgotten but shows its lineage... -- Nick nickz@idt.net IC XC + NI KA
