Advertisement for Mathatronics Mathatron III Multi-User Calculator System, December, 1968
Thanks to Mr. Takaharu Yoshida for providing the scan of this original ad.
The Mathatron III electronics package provided connections for up to 16 Mathatronics
PKB (as pictured) keyboard units (which could connect via hard-wired or
dial-up telephone lines), ASR-33 Teletype terminals, or other serial-based data terminals
such as CRT terminals (which were very new technology at that time).
This system differs from the earlier
Mathatron II system in that it is significantly faster,
due to the replacement of the systems memory technology from magnetic
core-based shift registers to much faster, but volatile (meaning that
when the power was turned off, any data in the registers was lost)
solid-state memory.
