Does it have a product ID like 16800- or 16900- ?

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.

Astrodev:
Not sure about the memory depth as that seems to be a licensable option suggesting the boards are built with the full memory and crippled until a licence  key unlocks it, might be something worth looking into if this is the case.

There is an EEPROM and a nice JTAG header on the 169xxA acquisition board, and the 34 channel board is actually a 68 channel one, probably with 34 channels disabled by a board ID on the EEPROM.  The 16910A (102 channel board) has all the components soldered, the 34/64 channel board, has some unsoldered parts.

The 16800-97014 service manuals lists the logic model replacement parts as:
16912-68702 34-Channel Acquisition Board Assembly
16911-68702 68-Channel Acquisition Board Assembly
16910-68702 102-Channel Acquisition Board Assembly

While there are standalone 102-channel 16910A and 68-channel 16911A analyzer module products as far as I know there was never a standalone 34-channel 16912A analyzer module product. Maybe it was easier for production to only produce the 68-channel and 102-channel populated versions and software cripple the 68-channel version down to a 34-channel version even if they never had plans to allow a software license upgrade from 34-channels to 68-channels.

I just took a look at one of the standalone 16911A modules I have. It has a Xilinx XC18V04 4,194,304 configuration bit device labeled as CONFIG EEPROM. I wonder if the configuration bitstream is the same for all modules with the same speed and depth options installed, or if it is unique on each module and serialized with other components on the module. I currently have two 16MB 16911A modules and one 32MB 16911A module. I wonder how easy it would be to dump the configuration EEPROMs from the modules and compare them.
