CEV First Report, Appendix 2C, section 11, p. 189;
"The Programming/Reading Unit seals peeled back easily without damage.
Inside, the system is composed of some standard EPROMs and a 68000
computer with standard 7400H TTL logic. The seals on the voting machine
peeled back equally easily. Four Philips head screws had to be removed.
The voting machine uses the same circuit board as the
Programming/Reading Unit, only with different peripherals plugged into
the numerous (11!) connectors."
