1988? - IBM PC at work, had been running free Spice for years by then - no schematic entry - had to enter netlist text file - sure beat punch card "decks"

I remember doing that -- decided to wait until it got better and more integration then tried a few and settled on Microcap ever since it became available.

For me, 1978. SPICE ran on the company mainframe in a glass-walled, raised floor, air conditioned, limited access room. We ran SPICE2 version D (pre 2G6!), and yes it ran from decks of punched cards. Fortunately there was an '026 keypunch that engineers (rather than trained keypunch operators) were allowed to use. Hand your deck to the SysOp, make sure your JCL included a comment with your phone extension number! Come back 2-3 hours later for the results: a 2-inch-thick stack of fanfold printer paper. Then whip out your colored pencils and connect the dots.

At the time, DRC still was done with plots, rulers, eyeballs, adhesive dots, and summer interns.

Even today I get this funny feeling when I view a netlist.
Actually didn't like schematic entry when it first came around.

Velum schematics with reference designators blank until the last minute.
My employer still requires schematics with "not used" and "last used" only a few of us remember the actual need.

Problem today is you cant blame a bent corner.

Thanks for the memory lane
