While on the subject of the 16800 series, has anyone here tried swapping out the logic analyzer module(s) for other standard analyzer modules, and if so, does that work?
As far as I can tell from the 16800 series service manual and the 16901A service manual they are pretty much identical, at least for the two module 16804A, 16806A, 16821A, 16822A, and 16823A models. The one module 16801A, 16802A, and 16803A models have a different Module Interface Board and one of the two power supplies is lower rated (15W vs. 175W, in addition to the common 600W supply). That must be to save costs on the lower spec models.
From the part numbers in the 16800 series service manual it appears that the analyzer modules might be standard 16910A modules and the pattern generator module might be a standard 16720A module.
I wonder if the 16800 series modules could be swapped out for any of the 16900 series supported modules (16720A, 16740-42A, 16750-52A, 16750-52B, 16753-56A, 16760A, 16910-11A, 16950A, 16950B, 16951B, 16962A). Or maybe the analyzer software will detect that mainframe is a 16800 series and only support the modules that are specific to that series.
If a module swap worked it might be an easy and not so expensive way to upgrade a 34-channel 16801A to a 68-channel system by swapping in something like a 16750-52A, and also getting up to 16M or 32M sample depth.
