So, I found three VAXSTATION 1's, and I can find little about them... Other
than the one-liner that Wikipedia has about them. Does anyone have any
more specs on these?

Do you have physical access to the systems to inspect them? A MicroVAX
I consisted of an M7135 Data Path Module and an M7136 Memory
Controller Module, which made up the KD32 CPU, mounted in a BA23
chassis. The memory was regular Q22 bus memory, such as M8067 MSV11-P
modules. The disk controller at the time was an M8639 RQDX1 module.

I assume a VAXstation I would be the same as a MicroVAX I except with
the addition of an M7602 VCB01 / QVSS module plus monitor, keyboard,
and mouse.

I only had one for a few months, but that sounds right. The display controller I remember
was a one bit per pixel (black/white only) display, just a bitmap (no hardware assist
other than perhaps to display the mouse cursor). Software originally was VAXwindows, then
that was canceled and the first X based software appeared in its place, a significant
improvement in features as well as speed.

Yes, I do...
I believe what you are saying is probably true.... The diagnostic floppies
that I found with these, one set in the Vaxstation I user guide, still
shrinkwrapped, were labeled Microvax.

Cool.

That is essentially it. Between maxxing out at 4GB of RAM and how
slow the KD32 was, ISTR they didn't last long after the MicroVAX
II/VAXstation II came out a few years later.

(We all know you mean 4MB, not 4GB).

Q22-bus MicroVAXen
KA610 aka KD32 was the first Q22-bus MicroVAX made. It is also the
worst VAX ever made. This is because it violates the two-layer bus
structure requirement (see above). KA610 aka KD32 is the only Q22-bus
MicroVAX on which there is no bus adapter or any other kind of nexus
standing between the CPU and the Q22-bus devices. KA610 aka KD32 uses
the Q22-bus as its VAX main bus and Q22-bus memory as main memory.
Among other horrible things, this means that the main memory is
limited to 4 MB and that no scatter-gather DMA is possible.
