I once "owned" the NetBSD MIPS port, and I've done VAX assembly and kernel code j(e.g., VMS device drivers). If I can't figure it out by comparison to 3100 code, I'll contact Ragge and set up remote access via a BCC08, a NetBSD laptop, and serial. (At least one of the VS200s is jumpered to Vaxstation mode, and I have two GPX daughter-cards on order.)

I am located in the San Francisco Bay Area. I came here for grad school and never left.

 It may be time for me to buy a PROM programmer. Anyone got recommendations for a budget device? "Amazon's choice" is https://www.amazon.com/dp/B082D5NQ2P. The costlier option includes 10 different sockets, and it claims support for 29xxx and 29Cxxx EPROMs, plus lots of others.

The DEC-badged Data-IO " on eBay is tempting, but expensive, and I don't know where to find software.
