? The VAXbrick is an update-solution for VAX 3000 and VAX 4000-200 based systems. There is still some information at HP: "CPU and memory from pre-upgrade system must be removed. The VAX 4000-50 Brick is a sealed unit which takes up the CPU and Memory slots in a MicroVAX 3000 series, VAX 4000-200 system, BA215, BA211, BA430 or BA431 enclosures. Must have VMS minimum version of 5.5-2h4 or 6.1 or higher, VMS 6.0 not supported." http://h10025.www1.hp.com/ewfrf/wc/document?cc=de&lc=de&dlc=de&… The board on your picture displays a unit to be specifically used for realtime applications and, from my point of view, is thus not meant to be used as an upgrade for typical "general purpose" vax-based applications. I didn't know rtVAX was also offered on boards with ISA-interface, though. Kind regards, Pierre

Wasn't there a discussion on that thing a while back? It's an rtVAX 300... Very interesting card... Anyway, as far as the VAXBrick goes, I'd think somewhere around $500 or slightly less for the CPU itself, and probably at least that for a system that could hold it... I thought I'd read it could work in a BA215, which would be a pretty nice setup. I'm sure the guy won't take it... -Ben ________________________________________ From: cctalk-bounces at classiccmp.org [cctalk-bounces at classiccmp.org] on behalf of Holm Tiffe [holm at freibergnet.de] Sent: Tuesday, January 21, 2014 1:43 PM To: General Discussion: On-Topic and Off-Topic Posts Subject: Re: VAXBrick value?

Next Thing is, that the firmware on this Brick is marking a memory area as bad, leaving some configuration information there. NetBSD doesn't care about that "bad" marking and overwrites that memory are, I had to dig into NetBSDs VM Subsystem to prevent this, but I'm really not such a VAX Guru that I could do this (alone). The other Guys at port-vax at netbsd.org wherent that much interested in that thing. So far as I know it is a full CVAX implementation with an Lance Ethernet Controller. Theoretical it should be able to run VMS, but it isn't supported. At least the MMU isn't castrated like that modified KA630 that is also used for thet realtime os (forgot the name for now). I do have an VME Bus Version here too. I do know nothing about the VAX-ISA Bridge on that board. There are some Altera CPLDs (as you can see) that make such a bridge. In the PC it was mounted it could boot from the PC's adaptec SCSI Controller (PC hosted Support Software for sure).. Regards, Holm -- Technik Service u.
