SPARCstation Voyager - Any history?
Cleaning up a non-post’ing SPARCStation voyager 146 (are there others?) and found a crude cat drawing on the silkscreen: https://twitter.com/salgernon/status/1029474524100616192?s=21 Just curious if anyone knows any backstory for this kitty.

Having used one in the mid-80s when they were brand new (and $10,000), they are quite slow and painful and limited to, I think, various versions of MicroVMS and VMS 4.x, depending on disk size (MicroVMS fits on a 30MB disk when the full version would not). I don't recall if there is any support for them in VMS 5.x - the max RAM is 4MB (unlike later Qbus VAXen, the RAM is _on_ the Qbus) but one could easily put a newer disk controller in there other than the RQDX1 and a larger disk. Be aware that most (if not all?) QBus SCSI controllers appear to be incompatible with the MicroVAX I. I'm not entirely sure why this is, but none of the Emulex, CMD, or Dilog controllers I've tried are listed as compatible with the system -- they all state compatibility with the II and later .I've tried using them in my MicroVAX I with no success. VMS fails to boot, and Ultrix kernel panics. Not to hijack the thread, but does anyone have any idea why this might be?

See https://ia801902.us.archive.org/11/items/bitsavers_emulex1987_5921218/1987_catalog_text.pdf page 27. The UC07/UC08 is documented not to support the MicroVax I due to lack of Scatter/Gather support. See https://ia801902.us.archive.org/11/items/bitsavers_emulex1987_5921218/1987_catalog_text.pdf Section 1.6.3 Page 1-22. Having no Scatter/Gather (aka Qbus IO Map) is not a surprise as the MicroVax I only uses Qbus Memory directly. Thus mapping to a larger physical address space should not be needed (micronote #22). However, I don't follow what changed to lose support on the UC07/08. Jerry

It's not as common as M9047, and not as convenient, but it works. There's reportedly also an M9037, which I've never seen.
Single-height Qbus grant continuity PCB
All the PDP11 people here will know the little square grant continuity board used in Unibus machines, along with the later dual-height one that also connected the NPG signal. And the common Qbus grant continuity board that was also a full dual-height one that had a couple of pairs of pins linked on one of the connectors. But I have here a little square board (the same size as the older Unibus grant continuity card) with just 2 pairs of pins linked. In the etch is a Digital logo (so I assume it's a real DEC product) and : LSI11 Grant Continuity G7272 5012564B Side 2 Has anyone come across that one before? -tony
