Scientific American looks awesome. Love the ads too,
p21:
Atari's new remote
pre-programmed computer ping-pong
game can be used with any size TV set, black
and white or color.
p14:
> HP's 9825A: a powerful new
desk-top computing system.
Through its novel architecture and speed, the 9825A runs
programs, accepts keyboard operations, and controls
instruments-with apparent simultaneity.
...
> The 9825's storage capacity includes
8K bytes of internal read!
write memory, expandable to 32K
bytes; in addition, each bidirectional
tape cartridge can store 250K
bytes. Its built-in tape cartridge
drive can access data in an average
of six seconds, and transfer data at
2750 bytes per second. At these
speeds, and with memory load and
recall capabilities not previously
found in desk-top systems, it becomes
entirely practical to interrupt
a long program, transfer it to tape,
run a short program, then reload
and continue the first one.
