Summary of USPS Equipment Upgrades
Multi-position Letter Sorting Machine (MPLSM)
| 1969 | ZIP Mail Translator (ZMT) - Converted keying (cordal) to sequential keying.
MPLSMs from simultaneous ZIP Codes keyed by operators then could be translated by the ZMT into BIN assignments. |
| 1973 | Engineering Data Isolation Technique (EDIT) - An electronic modification to the ZMT which allowed keyed data to be monitored for accuracy. |
| 1974 | Automatic Density Analysis Profile Technique (ADPT) -- An Upgrade
that enabled automatic tabulation of MPLSM sweepside BIN densities. |
| 1976 | Electronic Sort Processor (ESP) - A modification to MPLSMs which
replaced mechanical code setting with electronic code setting to
provide more accuracy, reduce maintenance costs, and reduce noise. |
| 1978 | Micro-Key - An upgrade to the ZMT which allowed the first digit of a
carrier route number to be locked in each time an operator keyed an
incoming secondary distribution. |
| 1981 | ZIP Data Logger (ZDL) |
| 1982 | Electronic ZIP Retrofit (EZR)-- A modification to MPLSMs to allow
four digit keying of ZIP+4 Codes. |
