I was curious to see if anyone mentioned VMware as an emulation environment
on this list. The archives show a brief conversation about it in 2002
regarding whether it could run OS/2.
I've been using it for a client's servers for the past few months and
it is mind-blowing. Drag-and-drop, super-fast start and stop of entire
virtual servers.
One of VMware's demo appliances is a DOS environment running old games.
Linux large and small is a common OS in appliances, too.
With the free VMware Workstation version, you can easily click-click
and be running a downloaded appliance.
So why aren't we using VMware appliance images to exchange pre-made,
pre-set environments for running emulated OSes?

Hi! It pains me to ask this, what vendors are hobbyists using for low cost,
low quantity prototype PCBs?
I've used Advanced Circuits and they've been pretty good. I would love to
stick with them as their barebonesPCB is a deal. 33each looks interesting
too. However, I am starting to have problems with them unrelated to the
PCBs and am investigating what other sources are available.
I am trying to get some prototype PCBs to evaluate some S-100 boards in
development (S-100 System Monitor Board, S-100 Bus Extender, S-100 Z80 CPU,
etc)
Any ideas? Constructive suggestions appreciated. Thanks in advance.
Have a nice day!

FWIW, I have one that does exactly the same. It is however also a
non-runner, so I can't tell you whether that's correct behaviour or
not. It certainly /sounds/ the same as my other, working example.

Mine had that too. Not sure where it came from, but it stopped when I
retightened one of the corner HDA mountings (the ones with the rubber
bushes underneath).

My AlphaServer 1000A 5/333 and 5/400 both beep during or after the POST.

I also have a number of DEC machines that failed after sitting for a few
months. I posted about them around the time of the "Leaving computers on..."
thread about a month ago but I never saw my mail make it to the list for
some reason.

The CPU module is removable and I have had trouble with one of my machines
fixed by reseating it. However, the symptoms were different - there was
activity on the display and there were beeps giving error codes.
I have also had a problem with a failed Bcache on the CPU module (it seems
this can be a weak point on the AS1000A) and I had memory failures. However,
neither stopped the POST displaying on the LCD nor the graphics console from
working.
I would suggest reseating the CPU module and removing any PCI cards present.
(I have an Alphaserver 800 which became a complete brick while a combination
of PCI cards were present that it didn't like.) If there are any EISA cards
present, I would leave them in place because there may be issues with the
config utility that has to be run when the EISA bus configuration is
modified. Other than that, I suggest trying the system with just the bare
essentials present and seeing what happens.
It would be useful to know if the fans start. Fan problems on some alphas
cause the whole thing to shut down. Also, there is an interlock microswitch
to prevent power up when the cover is open. This is probably not the problem
here though as the symptoms are as if the front panel power switch is off.

Just my luck! I'm making the final backup copy of my old Mac G3,
and one of the drives dies, and my other backup wasn't.
I take it apart - it's a 20 gig IBM Deskstar DTLA-305020, just
old enough for the (cough) ten-year-rule, and well-known prone to
two modes of failure, click of death and NVRAM failure. I'm hearing
the NVRAM failure sound as shown at:
http://www.dataclinic.co.uk/ibm-deskstar-hard-disk-drive-data-loss.htm
In googling, I saw one reference to someone replacing the 8-pin NVRAM
themselves from a donor drive, but that seems risky to me.
I think I'll send it to Gillware.com, a Madison, WI-based recovery
place. They offer $400-700 Windows recovery but charge a premium
for Mac recovery ($700-$1000) and Linux ($800-1000), with the higher
price for "clean room recovery". (Hmm, I thought bits were bits.)
Any other advice - besides a better backup strategy?

I found what purports to be a diskdef for cpmtools, but am not having any
success at all. The file _appears_ to copy into the image and I can read
it back out uncorrupted with cpmtools, but when I write it to a disk with
Dave Dunfield's NST and boot it, the file is filled with E5s.
I did note the diskdef is for 70 tracks (double-sided) and tried changing
the track value to 35. No luck.
I'm trying to move the Morrow HD format/test utility to a diskette that
can be accessed from my N* CPM 2.2 boot diskette, but so far it's "Can't
Get There from Here..".
I'd try a comm program, but guess what I don't have on an N* diskette?
:-).

Hi Will:
Do u know the model number?
If it is a Wang 2200 LVP, it is one of the first in its price class to come
with a fixed hard drive; initially it used a Shugart SA1000 and then it
switched to a Quantum Q2000.

Not sure if it may have been you posting on this thread, but here is
an old discussion of PC/ix:
http://www.vintage-computer.com/vcforum/showthread.php?11151-PC-IX-Images
The OP had posted disk images but the links are now dead. Trixter
(who I believe is on this list?) also downloaded them. Maybe he still
has them? I wouldn't mind giving it a try on my idle XT, too.

Hi
I might have a lead on a HP rx5670, but HP indicate that it might not
support VMS, and I'm not that eager to run linux, hpux nor windows.
Has anyone tried to run VMS on it?
