simultaneously. Ahhh. The joys of microcoding for a 74S181 ALU.
Now there is a blast from the past. I was working at UT Austin in '82 on my EE. I had to work part-time at the school for a non-classified project for the DoD (only way they would let students work on projects on the main campus). We were building a non-Von Neumann RTL (mono-bus computer) based router for the ARPANet using the 181's clocked at 40MHz (fastest they were reliable at) as the ALU's behind the registers. Couldn't find a way to saturate the machine (had 64 serial ports driving 64 Z80's @ 4MHz sitting on the RTL bus as addresses registers) on I/O. One of the guys working on the project was taking an electronic music class from one of the members of Journey (who was teaching a 1 time 1 semester class on electronic music) so we ended up using it as a synthesizer. Worked damn well. Don't know what the DoD did with it afterwards. Thanks for the reminder of some fond memories. Jim Choate CyberTects ravage@ssz.com
