A VAXstation 3100 can run versions of OpenVMS later than 5.4. -- Eric Dittman dittman(a)dittman.net

"How do we get the most money out of the software?" Which is the fundamental question. So it started with "Mainframes" and time shared systems. One big system, hundreds of thousands of dollars, can only be afforded by sharing time on it with several people. When you paid $500,000 for a computer you didn't bat an eye at paying $30,000 to license the software that let you run it as a time share system. Now technology relentlessly marches forward and you can "create" this time sharing architecture in a "single user" machine. No way you're going to get $30,000 for software for that machine, so you dress it up for the end-user (leave out serverish things, add a frame buffer) and call that a VAXStation. But wait, its actually just a VAX underneath and maybe you can capture a few bucks by selling it to people who _want_ a time share system, but they don't have a machine room. Now we'll call that a "MicroVAX". Same hardware, different target, different name, and more importantly, software for the MicroVAX was _much_ more expensive than software for a VAXStation since it was for multiple users. It used to be that people found this out the hard way when they removed the frame buffer cards and suddenly the OS believes its on a MicroVAX rather than a VAXStation and the license PAKs all refuse to work. So the only difference between a MicroVAX 3100 and a VAXStation 3100 is that the ROM of the latter complains when there is no frame buffer :-) You can run them both headless or with heads, both will run VMS 7.2 (the latest), and both will run NetBSD 1.5 (also the latest). The Hobbyist licenses (currently screwed up at the moment) work in either mode. --Chuck

A VS3100 isn't a "crippled" version of the hardware, but you wouldn't want multiple users slowing down your graphics updates. So DEC decided to market a VS3100 as a single user system where the full CPU power was available for graphics intensive applications, and the uVAX3100 as a multi-user machine. You CAN install a multi user VMS license pak on a VS3100 and have more than one person log in. DEC did offer a crippled version of the uVAX II (Or was it a VSII/GPX?), that had most of the expansion slots filled with epoxy to prevent upgrades. This was sold at a steep discount, but there was a run on replacement uVAX II qbus backplanes and the line was discontinued... Clint On Sun, 8 Jul 2001, John Allain wrote:

Also, when you have the graphical head enabled on a 3100, the licence manager can sense that and you can load workstation licences. Otherwise you have to load server licences. You can make a vaxstation into a vax (at least from the licence manager's point of view) by throwing one jumper and running the box headless. -- Jim Strickland jim(a)DIESPAMMERSCUMcalico.litterbox.com ----------------------------------------------------------------------- BeOS Powered! -----------------------------------------------------------------------

I'd like to consider attempting to optimize it if possible - kinda-of worst case is to read each block in order which requires 4 passes of the heads. I'm wondering if it's possible to do it in two passes if you don't mind reordering the data on the receiver's side. The cables look somewhat straight-forward. I was thinking of making a PC-floppy-to-TU-58 power supply harness (plenty of parts here) and a 2x5-Berg-to-RJ-45 board so I can hook the TU-58 into all the modular serial stuff I'm using here (got a small pile of Cisco serial connectors and flat-cables - the way they have this stuff wired up, if I trade out their ribbon cable with a 10BaseT patch cable, it's like adding a null modem (pins 4 and 5 are ground, 2 and 6 are TxD and RxD, etc) ===== Visit "The Seventh Continent" http://penguincentral.com/penguincentral.html __________________________________________________ Do You Yahoo!?
