Due to all the cool RSX utilities available from Jim Lopushinsky back in '84, I was able to make CP/M 2.2 and Molecular's N*Star MP/M-II-ish OS a lot more useable. I mistakenly told Allison that I thought I wrote this stuff! I just plain got it confused with what I did write...

[CCTECH] Seagate SMD disk info needed

by xds_sigma7＠hotmail.com

Well in terms of Emulex controllers, I have a circa 1983 emulex handbook that even goes so far as to list a whole lot of drives and say what controllers they work with.. hmm that out to be online methinks...

How do VMS Condists work?

No VMScluster and TruCluster (is that what it's called?) don't have much in common. They do not interoperate. But you could add in a spare drive and drop VMS onto that on you Alpha - you can boot VMS and it will leave your Unix disks alone if you don't mount them and vice versa. Then you cluster you VAX with your Alpha and and mount the CD and off you go. (It's that easy if you've done it before, you'll probably need a bit more help if you have not). For this to work your prerequisites are working ethernets at both ends and OpenVMS on both (same version saves a bunch of hassle). > >Hmm... That's an idea.

If this is either a VAXstation 3100 or a VAXstation 4000 then obviously it will have SCSI and adding a CD should be straightforward. If it is a VAXstation II/2000/8000/3500 then you'll still have problems (although if it's a VAXstation 8000 I'd like to have your problems :-)) Antonio

CP/M coding question

> -----Original Message----- > From: Pat Finnegan [mailto:pat@purdueriots.com] > where the CCP is > so I don't overwrite it. I don't know. If it's generally in a "normal" place, you could just find the size of CCP, and add that to the address. I don't think that would work, though, :) > Alternatively, would it be a better idea to write something > that loads its > own replacement CCP under it, and overloads the old CCP just under the > BDOS? I would probably need to intercept the 'JMP WBOOT' and This is what I was about to suggest. This way you could know exactly where, and how large, it is.

I'm possitive you can't cluster DEC UNIX and VMS (though there is a slim possibility I'm wrong). My question would be, if DEC UNIX can read the CD-ROM, can't you just transfer the savesets you need over your network? Zane

Fujitsu HALstation 330

by dwightk.elvey＠amd.com

Hi I used to work at HaL. I don't have any of the stuff you need but I'll ask around. It is funny that when working on some of the machines made by other people I can't understand why they didn't save some of the information for future use. Here I was working there and I don't think I saved anything. The HaL boxes were the first Sparc64's. Still they did take a specialized OS. This was mainly for the I/O drivers. The processors used in the early machines were some of the first to use such things as out of order execution. Basically, the processor would prefetch a number of instructions ahead of time. If it saw an instruction that didn't seem to have dependencies on previous results that might not be available yet, it would execute them to fill, otherwise, dead processor time. This was fine for most everything but I/O and some process handshake in multitasked. Someone forgot the I/O problem. I/O that needed to be ordered had to have enough 'nop's inline so that the next I/O was not in the prefetch. This required special I/O routines, even though the machines were otherwise compatible with other Sun code. I don't even recall if the 330 was a R1 or a R2 processor. I guess I can't blame others for losing computer history when I'm part of the problem. I guess we should all make efforts to save information as we go along. The hard part is to recognize when we are at a significant point in time. Dwight >From: "Dan Wright" <dtwright(a)uiuc.edu> > >I just picked up one of those today.

CP/M for the C-128 (was RE: A couple of firsts for me (Commod ore))

I > suppose it's copyable with a C-64 and two 1541 drives? If not, I do I'm not completely sure, but considering how much of the logic was in the drives and not the system, I'd guess you can copy it even if it's not the right system to run it. As for whether the 1541 drives are GCR, your guess would be as good as mine, but mine would be 'yes.' > have a C-128 - the later (AFAIK) model with the built-in disk drive.

I'm not completely certain how the commodore 128 CP/M works, but if you mean to extract the contents of the disk to a peesee, I can imagine that may not work as expected. :) The only way to be sure is to try it, though.

How do VMS Condists work?

by erd_6502＠yahoo.com

I received a stack of VMS CDs (originals) from a friend. I have no experience with VMS distrubutions on any media other than tape. How can I tell from the dates what version of VMS is on them? Is there a one- page "how-to" for CD ConDists? Were there seperate distros for VAX and Alpha OpenVMS? Any pointers for a newbie to VMS-on-CD-ROM would be helpful.

Right, and they're all condists, right? (I missed that part before) Does VMS come with the condist, or is it just "other stuff?" Never seen one, myself, though I have come across VMS OS media on CD before.
