); SAEximRunCond expanded to false Errors-To: [EMAIL PROTECTED] RETRY Hi all,
I have been lurking here for quite a while but here is something I can ask about! > A little known piece of Sputnik history... > > http://www.hparchive.com/Journals/HPJ-1957-09-Sputnik.pdf I have a couple of restored and working HP 524B/C counters, each 8 digits wide with nearly 100 tubes. They work well and the OCXOs in them are still pretty close to my two GPSDO references after 50 years! As it happens I have one out on the bench at the moment replacing the unobtainum delay line with a digital delay circuit. This article reminded me that I would love to find the matching 560A digital recorder - both my counters have the optional interface kit for it installed. Even though I am down here in sunny Australia, our dollar is strong and I would love to hear from anyone who knows where one might be found.
