This micronote documents the ECO and etch revision history of the
KDF11-A (LSI 11/23) module. A quick verify has been included so that
the status of a module may be determined by a visual check.
For the M8186, the revision identifier is a two field alphanumeric
designation stamped on the reverse side of the module handle. The first
field indicates the etch revision. The second field indicates the
modifications to this etch.
Hardware revision notation :
A 0
Identifies etch level Identifies modifications
The M8186 began as hardware revision "A0", as shown above. That is,
etch revision "A" with no modifications or rework. As ECO's were
released calling for rework, the hardware revision level was updated to
"A1", then "A2", etc. Periodically new etch revisions were released,
incorporating previous modifications. When these occurred the etch
revision field was updated from "A" to "C", and later from "C" to "D".
For the M8186, no etch revision "B" was released.
