NetBSD on Q-bus MIPS?
[ cC'ed to port-vax for Qbus/enlcousure questions. Please reply via email, or a single mailiing list, where not of interest to the list membership(s)]
Recent removal of NetBSD FDDI drivers prompted me to look at FDDI support. I just acquired a R4400 (decsystem 5900, and Q-bus boards for the 5400 (KN01) and 5500 (KN220). The DEC "PDQ" interfaces are the fastest available for Turbochannel or Q-bus machines. I bought a handful on eBay and I hope to revive the FDDI driver and make it MP-safe.
I started contemplating going down this route as a way to fuzz-test binaries (esp. Ultrix/mips binaries).
It's 30 years since I last configured a Q-bus. I already have PDF copies of the Technical Reference Manual for the KN01 and the KN220 boards. I'd appreciate any help or pointers or risks in configuring these systems in a BA123 "World Box'; or finding a BA213 enclosure with motherboard and the dual-height slot outside the CPU slot, for the DSSI distribution "paddle board".
There is a KA660 cab kit for the BA123, which should work with the KN220 (excluding DSSI).
Does anyone have experience with that?
thanks in advance
