OS X (lack of) tape support, was Re: [HECnet] tape image manipulations...

two dumb RSX questions

Nice! Real hardware! One day I'll get my 11/53 back up. Are you giving guest access and/or offering accounts?

tape image manipulations...

by clemc＠ccc.com

Many thanks. I think we all have created a library of tape tools over the years. I'll put on my todo this to get my set together. As for the OSX lack of mtio.h - i've just pulled it from FreeBSD and never had an issue - obviously there is not driver. I 100% agree -- it does seems nuts and I've b*tched at my friends at Apple about it a few times. Another thing I have on my todo list is try to slide the drivers back into an hackintosh i had running on a vm in a system that has an old DEC/Adaptec PCI card in it that I still use for SCSI tapes.

Re: TOPS-20 on HECnet?

by phiber＠phiber.com

Thanks Peter, I've been peering with Dave McGuire doing DECnet over GRE on an emulated cisco 7206 in dynamips/dynagen. Other than burning a lot of CPU cycles versus a much simpler Johnny-bridge, it works quite well. :) I'm GLGMSH (61.150) on HECnet, or gilgamesh.phiber.com on the Internet if anyone is looking for a reliable TOPS-20 Panda system to hang out on. Full e-mail, HECnet and Internet access. -Mark On Fri, Feb 14, 2014 at 11:32 AM, Peter Lothberg <roll at stupi.se> wrote: For HECnet I'm just running a plain old fashioned Johnny-bridge. :) I take it HECnet peers are lacking in the U.S.?
