I've gotten rid of a lot of wierd stuff in the past. BUt toiday, I still have some QBUS M68K boards. And I still have Terak boards (should qualify as rare I imagine) no Terak boxes but they work OK in any QBUS backplane.
I'm sure if I thought about it there is more. bill ________________________________________ From: cctalk [cctalk-boun...@classiccmp.org] on behalf of Pete Lancashire via cctalk [cctalk@classiccmp.org] Sent: Sunday, March 5, 2017 12:22 PM To: General Discussion: On-Topic and Off-Topic Posts Subject: Re: What's the rarest or most unusual computer-related item do you own? Here is what comes to mind, it may not qualify as a computer. A Westinghouse Numa-Logic PC700. It is an early PLC. uses a Sinetics 8X300 bit slice. Unfortunately Westinghouse only started to invest in PLCs about the time the they merged with CBS and in a few years all of Westinghouse became history. BTW Looking for parts, manuals, software, the "lug-able" CRT based programmer, IDE PC interface etc. etc. Also will get my Allen Bradly PLC with core memory running someday. -pete On Thu, Jan 12, 2017 at 11:49 AM, Rick Bensene <ri...@bensene.com> wrote: > > A selection of some of my more unusual computer-related stuff: > > - A Tektronix 4132 Unix workstation using a National 32016 CPU and a > 4.2bsd port called UTek > > - A Digital Equipment PDP 8/e system with 2 RK05 drives, high speed paper > tape reader/punch, RX01 Dual 8" floppy drives, 16K of DEC core > memory(commonly runs with a 32K NVRAM board), 2 serial ports, EAE, RTC, > Memory Extension/Timeshare board, Diode boot board (RK05 boot) > > - Wang 300-series calculator field service parts kit (two wooden > briefcases) > > - Friden 6010 Computyper Diagnostic Console > > - Friden Electronics Training Course manuals (1960s) > > - Wyle Laboratories WS-02 punched card programmable electronic calculator > (1964) > > - Busicom 207 punched card programmable electronic calculator > > - Altair 8800 with Altair dual 8" disk drives > > - IMSAI 8080 kit built in high school as a school project in 1976/1977 > > - Televideo Personal Terminal > > - GE transistorised current loop acoustic coupler modem (110 baud) > > - Hewlett Packard 9100A and 9100B programmable electronic calculators > > - Tektronix mini-Board Bucket computer and many boards for it (EPROM > Blaster, TI TMS9918-Based Video Board w/RTC, SASI Interface, 6809 CPU, 6809 > ICE CPU. 32K Static and 64K Dynamic RAM Boards, 300-Baud Modem Board, 5 > 1/4" Floppy Controller > > - SWTPC TV Typewriter > > - A large format (4'x5') Summagraphics digitizing tablet with GPIB > interface > > - A Tektronix 4052 desktop computer (bit-slice implementation of Motorola > 6800 CPU) with very rare RAM Disk module installed under keyboard > > - Wang Laboratories dual-cassette drive for 700 series calculator > > - An old fluorescent-lighted, two sided sign advertising Denon electronic > calculators > > - Some original Digital Equipment System Modules (Used by DEC for making > some of their early computers) > > --- > Rick Bensene > The Old Calculator Museum > http://oldcalculatormuseum.com > > >
