NT 4 on AlphaServer es40

I managed an IAS system on an 11/70 back in the day. I don't have any formal benchmarks, but it didn't "feel" any slower than equivalent RSX11M and M+ systems I have been on. Cool. The reason I mentioned it because of just such things as you mention below - device drivers being full blown tasks do imply quite a lot more overhead. IAS was a real treat. If you wanted them, you could SYSGEN in real timesharing features for supporting users who didn't require realtime response to their needs. It included lots of concepts that later made their way into VMS, (although, considering this crowd, I don't know if that will be considered a plus here...). Well, I for one don't mind VMS, even if I think RSX is way cooler most of the time. The most interesting feature for me was the way device drivers worked. Called "handlers", they were complete tasks, instead of the APR and a couple registers' worth of context provided by RSX11M/M+ drivers. You could do a lot more work in them, a lot easier than on the other RSX variants. The down side is that any driver action involved scheduling a task rather than the lightweight context switch required by a driver. But, having said that, the system I managed supported lots and lots of terminals at 9600 baud, and wasn't bogged down by servicing interrupts, so scheduling a task to do IO didn't turn out as bad as you'd think it would. Yeah. After having done a lot of device drivers and stuff in -11M+, I sometimes long for the freedom of a task context. That's when you go diving into ACPs, but it would be nicer if the driver was a task in itself. I managed RSTS sytstems as well and I vastly preferred the richer environment provide by IAS. I recall being at the DECUS Symposium where the future of IAS was announced (that is, no future...). There was much lamentation, gnashing of teeth and rending of garments over that. Support did actually continue for quite a few years after that though - turns out that the US Air Force was a big IAS user, and DEC didn't want to upset the government. BTW, I'm always looking for IAS related "stuff" - copies of the DeVIAS newsletter, IAS software (espcially DECnet-IAS) and the like. I believe IAS never went to Mentec, but actually stayed with DEC, for the very same reason (although I also heard that supposedly it was IRS, but urban legends are probably abundant). >Never seen TRAX in real life either, btw. What was so good about it? Me neither, though I did use some of the VT61 and VT62 terminals that were developed for it - like VT-52s, but with IBM style block mode. Not a lot of software outside of TRAX used their block mode features, so they were pretty rare. The VT61... The VT62 was a different beast, and I had one for many years... It's basically a VT52 with inverse video attribute.

I thought it was, LOL, is a half size 2", guess I guessed wrong, the flat cable gave me the impression. I never did anything with that drive except using the NT 3.51 that was on it originally (upgraded later to 4.0,) I have better read the documentation before I try to "fix" it LOL. I think NT should run on SCSI, I had a WIN2000 beta running on the miata a very long time ago, but the disk went bad, and don't know where to find a CD for it. In the mid ni8neties we ran a lot of NT 3.51 and 4 on alpha, but honestly, don't remember the hardware, has been a long time (for a senile guy like me.)

I'm wandering if I can use a regular alpha one or an ibm rs6000 one, have a few spares, just don't know if vms and the firmware may support it.

What I've found out with my Multias is that it is not recommended to use an internal drive at all, because of the additional heat it produces. The enclosure is not very well designed for sufficient cooling and therefore it is best to try to minimize the heat load in every possible way. An external SCSI disk or enclosure with disks (such as a BA353) works fine. Kari On 11.2.2013 10:20, hvlems at zonnet.nl wrote: Did you write IDE disk for a Multia?

All three were barracuda, I lost one machine (the miata, without counting a number of VAX, those have been dying faster, I'm down to "one" now,) but not the drives. The noise points to a bad drive, (hopefully not controller,) on linux boxes, pc and pc server hardware, I have had a lot of disk failures, sparc, sgi, hp9000 and ibm 6000 are built way better, hardly never fail, consider that those alpha (and the small drives they came with,) are now going to be 20 year old in a few months, the VAX is heading for thirty, in so I expect those old drives to fail sooner or later, I used to buy them by the lot, and still have boxes of small ones. I'm more worried when the machines fail, those are hard to replace, and parts may be really hard to find (like a multia floppy or internal ide.) Probably is time to image all those drives, and if worse comes to worse, run on stromasys or simh for the vax. cheers, daniel ;-) On 2/10/13, Michael Holmes <mholmes10 at hotmail.com> wrote: Found the hidden culprit.... The hard drive started making noises that I normally hear from a blender. The multia booted fine when I set it to mop boot without any local disk (slow but worked). So next weekend I'll remove (or replace )the drive and do the fan upgrade everyone recommends. Anyone know of any possible replacement scsi drives for multia's???

Bought a new (and expensive) floppy for it and same results.

I bought a multia several years back and I think it sucommed to being moved to and from Germany and the States too many times. I had it booting as a satelite off a DEC 3000 just fine, until this last move. I thought the battery had died and replaced it. (dead battery prevents the bios from coming up) I get the SRM console and i'd get MOP load message on the DEC 3000 but the MULTIA just hangs after message about bootstrapping. I heard something about an I/O chip that can go bad on the MB and was wondering if anyone had any ideas that could be used to fix the MULTIA. thanks Mike

NT 4 on AlphaServer es40

by clemc＠ccc.com

Yup the 11/60 had WCS, although few customers used it. CMU/3 Rivers had created the 40e with a WCS, and wrote a call/return instruction for C. We had a hacked UNIX to use it. When I was at Tek, Steve Glaser and I toyed with trying to write the uCode for the 60 to do the same thing to try to buy some more performance (it was the first UNIX box at Tek and quickly got overloaded), but we never did - as we replaced it with an 11/70. The 60 also was known for the confuse uCode instructions and since the front panel was run by the uCode the only solution was the pull the power to halt it.

One of them was used by WPS-8 development (running RSTS) -- because the 11/60 was the fastest PDP-8 ever built thanks to custom microcode that implemented PDP-8 emulation. paul
