This was a Massbus disk created by Shelby, which was varible size. Slight correction of myself. It was manufactured by SETASI, but was called "Shelby" apparently. There is very little to be found on the internet about it, but it was essentially a PC with a Massbus interface, and it used an optival drive for the RM06, or potentially a normal winchester, at which point they apparently also called it a RP12. Here is the basics from the wayback machine: http://web.archive.org/web/20010124161600/www.setasi.com/RM06.html Anyway, I just sat and read through the device driver code for RSX, and it looks pretty straight forward to implement. Johnny It would be a really nice thing to emulate. I can probably reverse engineer it from the RSX driver, and I don't know which systems ever supported it. RSX for sure. Possibly also RSTS/E, but beyond that is more uncertain. Most people and systems had moved on from Massbus before this drive came out. But it is a much nicer solution than emulating eight RP06 drives, when you have some big disk in the backend. Do you know what speeds this emulated massbus disk can achieve, by the way?

Hello Tim, All my simulated VAXen and PDP11s use VDE since it was available. I’m also using VDE for KLH10 (the “current” source tree also supports it). Theoretically, VDE puts more load onto the host OS and the network throughput is somehow lower, but in my opinion the flexibility it provides offsets those inconvenients. For instance, I can “plug in” the VDE virtual switch from my laptop using vde_cryptcab, so I can have “mobile DECNET” :) As an example, this is the /etc/network/interfaces of one of my machines (a Cubietruck ARM SoC running ARMbian, a Debian derivative): auto lo eth0 iface lo inet loopback #iface eth0 inet dhcp auto tap0 iface tap0 inet manual vde2-switch -t tap0 -n 16 -s /tmp/vde.ctl -M /tmp/vde.mgmt -m 666 --mgmtmode 666 auto br0 iface br0 inet static address 192.168.0.12 network 192.168.0.0 netmask 255.255.255.0 broadcast 192.168.0.255 gateway 192.168.0.128 dns-nameservers 192.168.0.128 192.168.0.12 bridge-ports eth0 tap0 upsysctl net.ipv4.conf.br0.proxy_arp=1 upip link set dev $IFACE promisc on down ip link set dev $IFACE promisc off This setup makes an ethernet bridge with static IP address, plugs in the real ethernet interface and a tap one, and creates a vde virtual switch plugs to tap0, so to the bridge. Then I simply attach the SIMH simulated NICs to /tmp/vde.ctl and have all of them visible in my network (no routing setup needed in the hosts). ___ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh
