A discussion about Raspberry Pi performance prompted this:
From the inside out:
- Raspberry Pi 3: 1.2-ish GHz quad-core ARM Cortex
- IBM System/360 emulator in IBM PALM bitslice CPU firmware
- IBM APL interpreter in IBM System/360 assembly language
Starting the show takes 17 seconds from clicking the Restart button (second from right, top row) to APL’s Clear WS prompt. I have no idea how that compares with a Genuine IBM 5100.
I distinctly remember writing APL programs, but that’s about as far as my memory will take me. [sigh]
