FLIP CHIP
Flip-Chip was a DEC registered trademark, named after the "flipchip" component mounting technique which quite rapidly faded from fame. The name was retained although the majority of Flip-Chips never really were flipchip-mounted.

Flip-Chip families
The various families were colour-coded, and the first letter denoted a colour, which was also visible on the handle.
A series
The A stands for Amber. The A series were used for analog functions - ADCs, DACs, etc.
B series
The B stands for Blue. The B series were used as core logic in the higher-end CPUs.
G series
The G stands for Green. The G series were used for "anything with non-standard voltages", I think.
M series
The M stands for ...? I'll have to find that out. Don't know what defines this, but I think it's "TTL-level logic".
R series
The R stands for Red. Slower logic than the B series, but cheaper. Used extensively in the I/O circuitry of computers.
W series
The W stands for White. These are components that plug into Flip-Chip sockets, but have no logic of their own.
