What's the rarest or most unusual computer-related item

I wouldnt be surprised if I were the only one with a Philips PTS mini, or rather a set of spares that can be combined into one. The PTS series is a swedish development, based on Philips P800 hardware, but with a lot of extra adapters so it could be used for banks, airlines, etc. BTW : I'm still looking for a 5 MB drive, called PTS 6876. It is also known under other (Philips) names. /Nico ----- Original Message ----- From: Rik Bos To: 'General Discussion: On-Topic Posts' Sent: Tuesday, January 17, 2017 3:58 PM Subject: RE: What's the rarest or most unusual computer-related item My rarest item is a Diehl Alphatronics a very rare combination of computer/calculator it's a same kind machine as the HP 9820A or some Wang calculators from the era (early 70ties). I also have the service manuals for this machine and some spares to keep it running. Other rare items in my collection are the HP 9821A actually a HP 9820A with a cassette drive like the HP 9830. And a HP 9831A which is basically a HP 9825A with firmware to run HP 9830 basic and a different keyboard, but the firmware also works 1n the HP 9825A. I also have part of a memory core module(6 layers) from an IBM 1401. -Rik -- I am using the free version of SPAMfighter. SPAMfighter has removed 10908 of my spam emails to date.
