Error Detector Monitor. This board is used in the decoding
system for the disc drive data paths of the Electronic
Stills Store. It can correct any single bit error and
detect any bit error in a previously encoded block of 88
bits in a NRZ serial data stream by use if Hamming code.
It also allows the use of interleaved data blocks for burst
error protection. Output is the corrected NRZ serial data
stream and flags to indicate the presence of a double
unsupported board. Parent equipment PA1M/S80. RD 1981.
DPCM Monitor. This card has a self-contained Z80 micro-
processor system which is able to take "snapshot" samples
of digital video data at various points in the DPCM system.
