He laughed loud and sarcastically and said that I should use water valves instead. He was the kind that (even way back then) liked to use highly integrated one-purpose chips. In frustration I partly switched myn interests to chemistry, which had a more adventurous teacher. More recently I dreamed about building my own CPU from all those RAMs, EPROMs and '245 chips lying around, porting gcc to it and running Linux. But realising that 10 MIPS is almost impossible to reach that way (1 is more likely) spoiled the fun.
