Who remembers debugging pdp-10 code by transistor radio? Put a radio close to the incandescent front-panel lights and listen to the static produced. I think Dave Plumer used to be able to diagnose tight loops that way. Sure would like to know where Dave Plumer is these days. Other of those guys, too. It was a treat to see the names in the Decus post the other day: Bob Clements (DTLOTS!) and Ian Pugsley and many others. Just great. ###### From: bugs@netcom.com (Mark Hittinger) Newsgroups: alt.sys.pdp10 Subject: Re: Debugging via radio Date: 12 Dec 2001 16:05:54 GMT Organization: MindSpring Enterprises Lines: 22 Message-ID: <9v7v92$9ac$1@slb6.atl.mindspring.net> References: NNTP-Posting-Host: c7.ae.21.58 X-Newsreader: NN version 6.5.0 CURRENT #121 Path: chonsp.franklin.ch!pfaff.ethz.ch!news-zh.switch.ch!news-ge.switch.ch!news.tele.dk!small.news.tele.dk!4.1.16.34!cpk-news-hub1.bbnplanet.com!news.gtei.net!newshub2.home.com!news.home.com!news.mindspring.net!not-for-mail Xref: chonsp.franklin.ch alt.sys.pdp10:8148 pwilson@TheWorld.com (Pete Wilson) writes: >Who remembers debugging pdp-10 code by transistor radio? >Put a radio close to the incandescent front-panel lights >and listen to the static produced. I think Dave Plumer >used to be able to diagnose tight loops that way. There was a great story told at one of the DECUS symposia about a contributed program (I believe it was contributed by Greenblatt) that would play music on a transistor radio. The story went that the secret next generation PDP-10 hardware was being tested at Digital and someone tried running the music program on the new system. The music didn't sound at all right and the tester phoned the author of the program to try and get some help to make the music program work. After listening to the radio noise produced on the secret box for a few seconds, the author of the music program exclaimed "wow thats a really fast machine!" :-) Later Mark Hittinger Earthlink bugs@netcom.com ###### From: Alan Greig Newsgroups: alt.sys.pdp10 Subject: Re: Debugging via radio Date: Thu, 13 Dec 2001 09:48:05 +0000 Organization: http://extra.newsguy.com Lines: 31 Message-ID: References: <9v7v92$9ac$1@slb6.atl.mindspring.net> NNTP-Posting-Host: p-415.newsdawg.com Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit X-Newsreader: Forte Agent 1.8/32.548 Path: chonsp.franklin.ch!pfaff.ethz.ch!news-zh.switch.ch!news-ge.switch.ch!newsfeed00.sul.t-online.de!t-online.de!news-spur1.maxwell.syr.edu!news.maxwell.syr.edu!pln-e!spln!dex!extra.newsguy.com!newsp.newsguy.com!enews1 Xref: chonsp.franklin.ch alt.sys.pdp10:8159 On 12 Dec 2001 16:05:54 GMT, bugs@netcom.com (Mark Hittinger) wrote: >pwilson@TheWorld.com (Pete Wilson) writes: >>Who remembers debugging pdp-10 code by transistor radio? >>Put a radio close to the incandescent front-panel lights >>and listen to the static produced.

In http://pdp-10.trailing-edge.com/www/lib10/0011/MBLURB.TXT there is a very brief mention that (NOTE: For simple, quick-and dirty listening, placing a transistor radio near the MI, or near Bay 2 of the KA10 will produce the music, but hardly in Hi Fi.) but the preferred way to play music is the MK10 "Music Kludge" :-).
