Nope. I only had to re-enter the boot a couple of times.

I remember two things about that class.

One, PDP-11 assembly language was elegant. Every addressing mode worked with every register, even when that didn't make any sense. I remember a single instruction that you could write that would cause the CPU to copy the instruction to the word at the preceding address in memory and then jump there. The end result was the address register (as displayed on the front panel lights) would continuously decrement. The machine was useless, but the result was fun.

Two, we built a small real-time multithreading kernel in the course. For all that the basics only required < 100 lines of code, it was pretty cool. It only supported two constructs - semaphores and context switching. We could still build pretty cool applications with it. The final project for the course was to read punch cards from a card reader, print their content on a line printer, and at the same time talk to a serial CRT terminal for displaying status. Getting the whole thing working was the first step. To pass the course you had to let the instructor halt the machine, dump the memory, and you had to walk the dump and tell him where every thread was executing and what it was doing. One of the most difficult classes I ever had, but also the most fun.
