Yes, and I can communicate with other VMs on the same physical machine without issue. I brought up a simulated alpha on the host and it can contact the simulated VAX fine, along with the rest of HECnet. i'm connected to the rest of HECnet through multinet's decnet-over-IP tunnel to Fred's systems.

embedded libraries for PDP-11, was Re: [HECnet] DECUS RSX C compiler

If the above suggestion doesn't get you anywhere, perhaps avrlibc could be hacked into a PDP-11 library. All of the hardware support will have to be ripped out of course, but there are nice tight implementations of generic library functions in there. I took a look at that. It seems to be largely assembly code, which makes it not very helpful. I've lifted more than a few routines from it, and they've all been C. Guess I just got lucky. Sorry for the false start. No problem. Meanwhile, I'm digging through the rt11 sig tapes from trailing-edge, which seem to have various bits of decus c in them. It's hard to sort out what's what but I ran across a directory full of libc type things in c. So that looks promising. I also found RSTS libc pieces, which is nice for another day... paul

DECnet on 4.3BSD/TOPS-20 and other questions

by mcguire＠neurotica.com

I think it'd be cheaper for me to find some DSSI drives. (Or add a DSSI <-----> SCSI adapter in to the mix ) Well, trouble is, they're drying up fast. Think I could make a VAX work with iSCSI? ;) That's an idea! Would be easier on a weekend due to my eyesight making me unable to drive, so i'd need someone to drive me there. Although I have a few friends a little ways from Pittsburgh who might be able to help in some way. Me getting there directly is a bit challenging, both due to my eyesight and possibly being the youngest here ;). Understood. I generally don't differentiate much between weekdays and weekends, so either is fine for me. (You have no idea how hard it is to get this working in a VM ). Oh yes I do. ;) I virtualized a gaggle of SCO OpenServer machines for a customer about two years ago, using VMware. Oh man that was a mess...VMware was the only virtualization platform that would work, and even that took some doing. They're all still running, though, but now on VERY different hardware. :-) At least it's not Hyper-V I couldn't get anything to run in Hyper-V save for windows. And not even NT 4! Eeeeeek! -Dave -- Dave McGuire, AK4HZ New Kensington, PA
