- duskwuff 12y agoIs it possible you're thinking of the PDP-8? The PDP-11 didn't have switches; it had a keypad (shown around halfway down the page), and could also have a boot ROM (present on this machine).
- Taniwha 12y agono I programmed pdp8s too - many pdp11 models had switches, especially the low end ones (the one in the article has an octal keyboard and a display - very hitech!), I used to know the paper tape bootstrap for our '05 off by heart(the one in the article doesn't, probably had a bunch of romed ones for various disks)
- theophrastus 12y ago..or even a PDP-12. Which was sort've an out of sequence lab machine based on their LINC ('L' for laboratory) machine. i ran a PDP-12 off an analytical ultracentrifuge and it had front panel switches which had to be set a certain way on boot-up.
- flyinghamster 12y agoSome -11s (like the 11/20, 11/35, 11/45, and 11/70) had toggle switch front panels. The 11/34 had the octal keyboard, and some systems like the 11/44 didn't have much more than a power switch. My high school, back in the day, had an 11/34 running RSTS/E with a bunch of terminals hanging off it. Our classes taught BASIC-PLUS and COBOL (actually WATBOL), but no assembler. The biggest irony? Back in 1980, my teacher was warning us about Year 2000 issues. Some years back, when I got a RSTS/E 7.0 system (the version that my high school had) running on SIMH, I discovered that 7.0 wasn't Y2K compliant!
