I am getting my PDP-11/34 and my RK05 disk drives and packs tommorrow, and I have a few questions.They have have been in storage for years, and, although they have been kept dry, they are probably dusty. Can anyone tell me how to clean the drives and the disk packs before I use them?

Our Spectrum Management Agency (or whatever it's called this week) has a

they should be able to watch marginal signals on "rabbit ears" inside a

I've been looking in my old Tek catalogues and the disk drives for the 4050
series are model number 4907, not 4097. This is from my 84 catalogue. Option
31 is three disk drives, option 30 is two disk drives and option 40 is 4052
and 4054 compatibility.

You have to be REAL careful which way the pins go on that. I had to
make two of 'em because the FAQ (where I found the pin assignments)
wasn't really clear which way you should be looking at it. (They ended up

I was lucky on mine. All of them came from the factory with a preset password
which was *something* like "MPC" or something like that. Anyway, it should be
in the 3B2 FAQ.
Where is this scrap place you are talking about?
I know there are a couple of them here, never thought of looking there
before. Do they sell you the stuff as scrap ?
Or by the pound..?

I did some research on this about 18 months ago in preparation for
contacting Commodore's bankruptcy counsel to see about purchasing the rights
to Commodore's 8-bit technology.
Even though I read the Chapter 11 reorganization plan and Chapter 7
liquidation motion, and my corporate counsel looked at the docs, it's really
hard to trace the chain of asset transfers, since I could not find a
specific list of those assets sold; only broad "all intellectual property"
language was used.
Collectively, Commodore's assets were sold to Escom (a German computer
manufacturer) for $14 million, $4 million of which realted to CBM and $10
million related to Commodore International Bahamas, Ltd. an affiliate of
CBM. The former CSG operation located at 950 Rittenhouse Road in Norristown
PA was purchased by GMT Microelectronics Corp., a company formed by former
CSG management in order to purchase the chip-making assets. The purchase
price was $4.3 million plus another $1 million to clear EPA liens. Assets
included the plant, equipment, other inventory items at that location. Last
year, I made a field trip to GMT and verified that they exist and are
operating out of the old CSG building.
The non-CSG assets stayed with Escom until they filed for receivership
(bankruptcy), in 1996. The assets were then sold to a Netherlands-based
company (Commodore NL??), who then sold the Amiga assets to Gateway (the
Holstein cow people). I don't think that anyone truly knows who owns the old
8-bit assets. Commodore NL sells PeeCee compatible machines under the
Commodore name, so I'd bank on Gateway owning them. If anyone on this list
knows anyone at Gateway, now may be the time to use the relationship.

Hmm, any other HP9000 series 500 owners out there? (I have a 520, but
would like to hear from anyone who has any FOCUS-architecture 9000s.)

Two RD5x's in a BA123 was definitely a supported configuration, and is
listed in the late-80's DEC catalogs.
Two RD3x (half-height) disks in a BA23 is also supported, and indeed is
the reason behind the 6-button BA23 front panel. Many 11/53
configurations were shipped from the factory this way.
Two full-height hard drives in a single BA23 was never officially supported
(at least for the various microPDP-11 configurations), because
they refused to support a base box sold without removable media.
