Convergent Technologies Workstation Product # 99-01640 "AWS"

For those of you who are Convergent Technologies Alum Facebook Group members, we have a discussion going about this over there.

We've just acquired this on eBay, sans keyboard:

It is labeled Convergent Technologies Workstation, but what model is it?

I've always been confused as to how Convergent's model numbers (according to their sales brochures and manuals) never match up to the model # or product # on the chassis ID tags.  This seems to be the case here also.

I believe it to be an AWS, but is it a 220, 230 or 240?  Or other?

These *should* be the hardware manuals from

So, about that keyboard...I'm pretty sure this is the correct one.  There's only one problem...I don't have one.

A very kind person who posted on has responded to me that he still has this one.  It doesn't sound like he wishes to let go of it, but maybe I can get the logic analyzer capture of each pinout?

Is 011384 the date?  January 13, 1984?

Or does the stamped 8351 to the right mean the 51st week of 1983?  or 51st day?

Look at that re-work!  3 chips high! 

It seems very much like this one on eBay

8513...and so, is the date the 13th week of 1983?  or the 13th day?  Or does this mean something else entirely?

2-83...or is that the date?  February 1983?
