In 1979 an outfit calling itself "World Power Systems, Inc." appeared on the scene with an amazing assortment of microcomputer peripherals, mostly for TRS-80 and S-100 systems.
Alas, they were scam artists, taking people's money and sending nothing in return. A hint of this is visible in a photograph of their 3S+P Interface Card, shown in one of their advertisments. Although it appears that the board has suitable compoments for three serial ports and a parallel port, careful examination shows that the PC board does not have anywhere near enough traces to interconnect the components.
Another suspicious product is their "Serial Parallel I/O Module" which purported to offer eight serial and eight parallel ports in one small box. Each of the eight serial ports supposedly had dip-switch selectable baud rates, etc., and each port could be configured for RS-232 or current loop operation. All for the amazingly low price of only $129.95 (kit) or $149.94 (assembled).
Remember, if it sounds too good to be true, it probably is.
I've scanned images of their ads from the April 1979 issue of Byte magazine:
Page 68, describing the
company, with photos of the proprietor (or should I say
perpetrator) Perry Pollock and his wife Korrine

Page 78, advertising the
Master Control Console, EPROM Programmer+3, and Serial Parallel
I/O Module
Page 79, advertising the
TRS-80 to S-100 Bus Cable Adapter, TRS-80 to S-100 Bus, and S-100
EPROM Programmer+3
Presumably Perry and Korrine were not the real names of the people involved. They're probably no relation to Perry Pollock, the Chicago-based artist, or to anyone else of that name.
