This month's Linux journal has a great article on SIMH and running an emulation of Unix R5. I took a look at the simh.trailing-edge.com site and found that they also had an emulation of the old IBM accounting machines and a software kit for the SPS (Symbolic Programming System) assembler. SPS was the first language I ever learned (the second was Cobol), so this brought back memories.
For you other old timers, maybe you flipped switches on a MITS Altair 8800 - they have that, too. Lots of PDP stuff; this is an incredibly fascinating resource.
The young folk might want to pull down a little of this stuff just to see why we old timers are as grumpy as we are: this is the software that molded us. It could also be amusing to look at sources and see the beginning of security problems that are still with us today.
Got something to add? Send me email.
