Hi, I haven't got ULTRIX/VAX V3.0C, but: V2.0 V3.1 (disk image only) V4.2 V4.4 V4.5 I'd like to have the missing versions, too. More ULTRIX-Manuals would be VERY interesting as well. (I scanned the ones at bitsavers.com) What type of VAX do you want to run ULTRIX on? Regards, Ulli

Looking for early versions of MicroVMS & VWS

I think I have some of these, but not 100% sure.

A complete system (in pieces) is on EBay @ 250390580244. Very reasonable at this moment... CRC

Of course, trying to back up > 30 MB onto a 95MB tape doesn't require perfect performance. No. You're mixing two different things. The speed of the drive is very much dependant on keeping the silos full. Otherwise it will go into start-stop mode, in which the speed gets horrenously slow. And I wouldn't be surprused finding out that a uVAX I can't keep a TK50 streaming. It's a slow beast. A "modern" PDP-11 is much better. However, streaming or not should not affect capacity as such. Block sizes on the other hand do. Doing small blocks drastically reduces capacity, since you have inter-block gaps on the tape. > Thinking about it, perhaps it's worth the effort to use Standalone > Backup - that should minimize any OS effects on backup speeds.

Well, from a performance point of view, both reads and writes should be optimized. Capactiry-wise shouldn't matter. Tape will start-stop and rewind as needed for both reads and writes. I'm looking through TK50 manuals, but can't find anything about inter-block gaps. The TU81 (for example) can have two different sizes of IBGs, which will affect capacity, and which can be related to tape speed. As I said, I can't find anything like this for the TK50, but if there is, it might cause what you are thinking of (except that the IBG is small by default when in start-stop mode on the TU81, and you have to explicity ask for a larger IBG). Other comments about TK50s? Well, they need a lot of cleaning, and you have to disassemble them when the pick-up skips the arm, which is pretty common. But anyone who have been playing with these drives probably knows this already. :-) Otherwise they keep working pretty reliably.

Gone but not forgotten- 10 operating systems most people have left behind

Article by some young puppy who doesn't know about any unices, RT-11, RSTS, VMS, or RSX-11. No O/S for big IBM iron either. Almost every thing he mentions is at least a generation newer than what most of us "We have said goodbye to some of them with regret. (So long, AmigaOS!) Some of them we tossed carelessly aside.

Hazeltine 1500 screen garbage; ideas?

by slawmaster＠gmail.com

Thanks to the generosity of Kenneth Marshall and his colleagues at the Laboratory for Laser Energetics, I now have a MicroPDP-11, RX-01, a whole box of miscellaneous flip chips, tons of documentation, and a Hazeltine 1500 terminal. Preliminary to setting up all the rest, I thought I'd try getting the Hazeltine working. I plugged it in and powered up, but the screen seems to be displaying random characters constantly while flickering... it's like somebody is sending a binary file over the serial line, except the serial line isn't connected to anything. Can someone with more terminal knowledge than me try to shed some light? I'm going to check very carefully to make sure no keys are sticking now... I don't think that's the problem but it sure would be nice if it was :) John -- "I've tried programming Ruby on Rails, following TechCrunch in my RSS reader, and drinking absinthe. It doesn't work.

Zilog System 8000

by lehmann＠ans-netz.de

Hi, I was able to acquire 4 Zilog S8000 boards lately. - S8000 Central Processing Unit - S8000 Winchester Disk Controller - S8000 Cartridge Tape Controller - S8000 ECC Controller I'm trying to get my hands on the Case and the 1MB memory card, but I was wondering if someone has still pieces of the S8000 at hand? What about tape images of ZEUS? I mean - when I'm getting the minimum required hardware sooner or later - without an installation tape I'm a bit lost - right? ;) I've tried to put all the information I was able to found about the S8000 together at http://pofo.de/S8000/ I've scanned the boards I got and put all the EPROM images online.

Anyone interested in VESA or PCI 486 PCs?

by lproven＠gmail.com

I am having a clear-out & I've discovered a cache of 486s in my garage. 4 or 5 machines, some VL-bus, some PCI. 486DX2-66 or better. All come with hard disks, RAM, network cards, CD-ROM drive if desired. I can provide keyboards too if desired. Free for collection from London, England. -- Liam Proven ?
