It's great to see these oldies get so much love. These are small enough that the power bill won't kill you immediately. The 'big iron' I worked with in the 80's required 400V tri-phase supplies and at todays' power prices you'd definitely think twice about starting them up.

Old PDPs also have their fanbase, and there is a ton of knowledge floating around about all these systems, sometimes more in the hobbyist sphere than there is left at the companies that built them (assuming they still exist). Of course you could emulate it all but the real hardware has its own kind of charm.

I see this one is here in NL, maybe I'll ask the owner one day if I can come by to have a look at the beast, it is definitely an interesting era to document in living hardware.

Very cool! It warms my heart that a few of you will keep some of these vintage machines alive. I’m guessing there’s FORTRAN on there somewhere. Curious what you paid for it?

Mostly RPG rather than scientific computing, though you could get COBOL, FORTRAN and of course an assembler. 500 KIPS and very small RAM so likely those compilers were multiple passes and required a disc.

What was system/3 used for?

It was a "minicomputer". Nowadays they are called "midrange" computers and nearly extinct. They were general purpose computers, used for all kinds of of operations/calculations.

Most minicomputers landed in companies/departments too small to afford a mainframe and where used for inventory, POS, bookkeeping, payroll, etc.

What was system/3 used for?

My mom used one in the 70s and 80s for accounting and billing in our local village. As I recall although they had multiple terminals to access it these were shared, you didn’t have a terminal on the desk. You’d pick the application you were going to use from a text menu, enter your identifier (no password), and make your entries. Actual billing runs or other accounting runs were done in batch overnight. When they upgraded to AS/400s everyone had PCs on their desks and used 5250 terminal emulators to access the system over SNA/APPC.
