Who remembers downloading pictures of pretty girls in ASCII HEX dump format, then using a local utility (???) to turn it into a picture?
Twenty years as a PF member: how many have been here that long?

The last serious piece of assembler code I wrote was in 1989 or thereabouts... My employer had a successful port of our Unix variant to the Motorola 88100, but to bring it up quickly we wrote strcpy and related functions in C as
and let the compiler take it from there.
Once the system was running I went back, looked at the pipeline structure of the microprocessor, and rewrote the byte copy routines in assembler with unrolled loops and picking up 32-bit words whenever possible (the 64-bit load/store instructions occupied two pipeline stages, so no benefit to using them). Several hundred lines of assembler to replace the single line of C code.... and one of only two times in my life that I coded a performance improvement that everyone could feel as the system booted.
