RSTS/E tapes, was Re: [HECnet] two dumb RSX questions

RSTS/E 10.1L will run nicely on a PDP-11/23+. I do it all the time. That is what PLUTO:: is. -Steve -----Original Message----- From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Cory Smelosky Sent: Sunday, February 16, 2014 21:22 To: hecnet at Update.UU.SE Subject: Re: RSTS/E tapes, was Re: [HECnet] two dumb RSX questions On Sun, 16 Feb 2014, Dave McGuire wrote: On 02/16/2014 09:15 PM, Cory Smelosky wrote: What're the requirements for RSTS/E 10.1?

It will not fit on a single RL02, unfortunately. ;) I should get that UDA50, order a replacement drive, pickup the PSU and run it on the 11/44, then. ;) I'll find another solution for the 11/23+. The {11/03,11/23} can be RT-11 or RSX-11M+. It fits nicely on am RM02/RM03 (~70MB), with languages etc. I don't know what the strict requirements are for the OS itself, offhand.

I seem to recall I got it to fit "comfortably" in 40M in simh. It took a bit of fiddling and I didn't have endless free disk, but I had enough. Come to think of it, my PRO has less than that. As for memory, I think 124 kW (max memory on 18 bit machines) is required. Hey, I have more than that! paul -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects

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

I think maybe it did not, but it's been awhile since I messed with OS X. If you note when you run "system info" the parallel SCSI kernel sub-system is still listed in the I/O section. Like Dave, it's been a while since I played with the Mach/Darwin kernel, but last I checked some of the pieces seem to be still there, i.e. a complete eradication of SCSI was not done by Apple. But at the time, I realized it was more than I wanted to mess with it. I have had some of the Darwin sources on my file server, and I'll try to take a peek later to see what is there. The issue I ran into is that since you are pulling the >>kernel<< support in, the support for the driver has to be in the key of that kernel which takes some messing around. The good news is from the user space all of them supported many of the same ioctl's and in particular used the *BSD tape interface - so I agree that in theory it should not be too hard. Clem

We will hopefully start putting down fiber here in "rural" sweden in a year or so. It will be a group of (not so technical) locals doing the planning and negotiations with ISPs. Any tips or gotchas I need to know about? /P

VMS Pak termination date ignored

by mholmes10＠hotmail.com

I noticed something weird last night. My multinet Pak expired and I had to get a new PAK online. I had to get my VMS hobbyist checksum to get my new multinet oak. While getting it, I noticed that my Hobbyist pak termination date had already passed but both alphas were booting up fine and not giving me the "expired license" notice like before. Has anyone else seen this behavior ?
