1. EEC-4 page omits manufacture by of processors and memories Toshiba, which began in 1983. Second sources were allowed for in original Intel contract. Most processors were in 68-pin plastic copper-leadframe flatpack 2. EEC-4 had more than 2 external memory or I/O devices in some modules, indeed early modules had stacked memories because software outgrew the PC board layout, and M-bus allows devices to jump on when they see their addresses.

Initial EEC-4 used NMOS Intel 8061, which had up to 8 channel pulse-measurement unit (HSI), 10 Channel pulse generation unit (HSO), plus on chip multichannel analog-digital converter and a customized serial port. Later devices used Ford-designed 8065 or EPIC CMOS processors, which allowed for more I/O, more interrupts, etc.

Worked on that for a decade! Skb999 (talk) 20:58, 10 April 2012 (UTC)[reply]
