Reviving a year old thread, did anyone get around to dumping the
VAXstation 100 firmware?

I don't see it where I looked here:

Well, it ain't in the 5150/5160 range!
The 5100 new was $10K to $20K.
I had a 5100 that a dentist had bought as soon as it  came out and he 
added the floppy drives and printer.  It was a direct IBM buy for 31000.

thanks

Also a fair amount of software.

Hello vintage computing fans across the country and around the globe
(that's right - we're international!) The 17th Vintage Computer
Festival Midwest is coming up in just two weeks! The hotel is sold out
(months ago!), the tables are all booked (and then some!), now all we
need is YOU!

I will be at the VCFMW both days.  I am bringing a bunch of 
stuff to sell.  I have a big box of Q-bus boards from my 
Micro-VAX II system.  I also have two ESDI disks that have 
VMS 4.7 on them, and an Emulex QD21 controller.  I'm hoping 
somebody at the Fest can image the disk that was last used.


I also have a Nat Semi 16032 system that I cloned back about 
1982.  This was built on the Multibus I bus.  Unfortunately 
I overwrote the disk with VMS when I set up my VAX.


I also have a whole bunch of Nat Semi 16032 development 
boards from a multiprocessor project  (Multibus I).


I also have a Multibus I ADC board from Data Translation.

I also have a Nat Semi 8500 graphics demo board.

And, not for sale, I will be showing a Honeywell Alert 
airborne CPU that was developed in 1965 for the X-15 
project, to help get the pilot back to Edwards AFB with the 
right energy to land in one shot.


It was the first all IC computer delivered.  (The Apollo 
Guidance Computer project started first, but due to the 
complex software, it was delivered a bit later.)

I found an ordinary handheld hole punch from stationery stores, that had a 
piece of clear blue plastic covering the lower jaw, that caught any loose 
Chad.  I didn't damage any 5.25" nor 8" disks using that.  But, obviously 
I still could have.


I supplied those with the Flip-Jig.

Flipping disks to use both sides in a single-side drive was really only
feasible in Commodore and similar drives that did not rely on an index hole
for locating the data on the disk; the notch was to allow writing to the
disk and had to be added on the opposite edge.

To use a flipped 5 1/4" disk in any other drive requires punching holes for
the index sensor in the opposite location, as well as the write (un)protect
notch; this can be tricky and it's easy to damage the actual 'cookie'
unless you remove it first.

All 8" drives use an index hole and also require punching corresponding
index holes but, as Jonathan points out, it's a little more complicated
because  the original location of the hole is different depending on
whether the disk is single- or double-sided .

On the other hand, you don't have to add a notch on an 8" drive unless you
want to write-protect it; the notch acts the reverse of the 5 1/4" notch,
i.e. notch=protect, no notch=write enabled.

Finally, there's the issue of the medium itself; if you're flipping
single-sided disks the early 8" disks are more likely to have flaws on the
unused side than the later 5 1/4" diskettes.

It it used the 13W3 D connector, I've used these (years ago) before with 
success:

Actually, not the specific brand, just 13W3 to VGA adapters...

Subject: [cctalk] Bringing up a Sun 386i: Can I use a modern monitor

Continuing my exploration of my old stuff pile I'm starting to work on
my Sun 386i systems. Old, no doubt but still there.

First step would be finding a monitor for them. The video cards I have
are the monochrome one, the CGI3 and a CGI5 board. For the color
monitors the cable I have goes to the RGBSync and of course to the
keyboard/mouse combination.

Question: Is there an adapter that can turn the Sun's output to HDMI or
VGA for a more modern monitor?
