I still have a PDP/8 with 4k core memory out in the garage. (a jillion RTL cards in it). It was free to e then, broken, ...I had to find t\all the bad transistors....
During college, ..I would sit in the floor with that thing and toggle in small programs in machine language to count up and down, seemingly impressing everyone with the binary lights dancing on the front panel. ...this all makes me want to pull it out and 'toggle' some more, again.... -Don ---------------------------------------- -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Bob Camp Sent: Saturday, March 03, 2012 6:55 PM To: Discussion of precise time and frequency measurement Subject: Re: [time-nuts] Questions about Austron 5000 Loran C receiver Hi Ahhh... The days of toggling the boot loader in with the front panel switches. So much fin.
