I have always used them interchangeably, but I never bothered to
check. The jack fit, I used it. I *assume* that Commodore would not have
made the 128 and A500's power supply ports be the same, unless they
believed the associated power supplies were compatible. Otherwise it would
be a product support headache. It would be a great advantage from a
repair/supply perspective to be able to use the same supply brick. That
said, only Commodore would do something as bone-headed as try to save money
by using the same power supply jacks/ports with incompatible bricks!

Err... I disagree with you Zane. I just checked
both of my A500 PSU's (made in Germay) and
my A600 PSU (made in China) and came up with
the following:
A600 PSU "Lightweight" (Part No. 391029- )
Input: 230-240V ~ 50 Hz 300 mA T1A
Output: 5V 3.0A
12V 500mA
-12V 100mA
A500 PSU "Heavy Brick" (Part No. 312503-02)
Input: 240V 50Hz 60W
Output: + 5V 4.3A
+12V 1.0A
-12V 0.1A
Going by those figures (on the underside of
the PSU's), I'd say the A500 PSU is the most
powerful.

About eight miles from Ashford in Kent. Ashford is where the channel

rail link has its last station before France, called Ashford
International. I am
out in the sticks but I can e-mail maps. My home has a claim to fame,
'The Darling Buds of May' was filmed here and in the surrounding
villages.

Yes this would be the perfect venue. Is this the building due to

That might work. I was told a AC battery, A round Tuit and a
green eyed lady were required. The problem is getting all
three in the same room. Seems they are atomic. ;-)
Now feet, do your stuff..

A couple of years ago I got an EAE off of ebay and it has never worked
with my -8/e. I was looking at it again and see that my M8330 Timing
Generator board is too early a revision to work with the EAE. I need at
least rev B (I think). Does anyone have a spare M8330 they could part
with? I kick myself for not grabbing a spare processor off of ebay over
the years. Otherwise does anyone have a working EAE that would be
willing to talk about with me?

So do I but all mine are 8". However having a H207 dual 8" makes it work
as the h207 has a very similar size and look as the CCS crate (long to the
back and narrow). As a result I've never fitted 5.25 to the CCS, no need.
I've been tempted to fit 3.5" drives to it as it would do 720/780k formats
as is off the 5.25 interface. All I'd have to do is tweek the BIOS for
that(2S, 80C, 512 format) and maybe tweek the formatter for 80 cylinders
and 2 sides.

These are 5 1/4" form factor floppies, but hold twice the data. I have
already
searched ebay and google, so I need other suggestions, or someone who can
part with some
I don't know if regular or "premium" 5 1/4 inch 1.2mb media can be
formatted
and used with them or not.
Thanks.

There is a chance that a little bit of carbonized something is providing enough of a load to
hamper operation, though. Pull off the cap and see what happens.
Also make sure that the board is intact, sometimes bits can get damaged by
"blasting caps".
I've recently come into possession of a VaxServer 3600 and a MicroVax I that I'm taking offers on. Don't really know anything about them and of course no way to power up. They appear to be in fairly good shape except the MicroVax I has a little damage to the plasic in the front. I also should be comeing into possession of a Tektronics 25" Video Graphics Color Console and a few other things that were described as museum quality. Items are in the Seattle Washington area.

I decided to pull out the CCS system and check. I'd forgotten as it
smaller than most s100 crates and it gets tucked away easily. It does
do 5.25" though the docs refer to 8" disti media only.
The Eprom on mine has the MOSS monitor and boot, IO expects standard CCS.
If you have CCS IO you at least have a monitor.
