The Model 212 could carry out a floating-point multiplication in 22 microseconds. Each word contained two 24-bit instructions with 16 bits of address information and eight bits for the opcode. There were 225 different valid opcodes in the Model 212; invalid opcodes were detected and halted the machine. The CPU had an accumulator register of 48 bits, three general-purpose registers of 24 bits, and 32 index registers of 15 bits. Main memory size ranged from 4K words to 64K words. Only the first model had a magnetic drum memory; later editions used tape drives.
The Model 212 weighed about 6,500 pounds (3.3 short tons; 2.9 t)."
So, for multiplication at least, the 212 was capable of 0.045 MFLOPS and 15.4 FLOPS/kg.. FLOPS/kg seems like a fun stat that we should probably calculate more often. The Earth's global computing capacity at the end of 2015 was estimated to be up 1.5e21 FLOPS, so the entire planet, elephants, mountains and all, produces just 0.00025 FLOPS/kg.. It seems like it might be a little while before the Earth has a higher computing power to weight ratio than this mainframe did, but probably not too much longer. It is just a piddly 16 doublings after all.
We had a couple of shared ties we’d drag out whenever we had a meeting with the chief exec. They were coffee stained and chewed but we were wearing ties and that was all that mattered to him.
Looking at old pictures is not a reliable way to suss the day-to-day of “the old days”, any more than looking at your Facebook pictures indicates how much you drink/eat/rock climb.
