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

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.

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.)
The System/34 is on wheels. You do need to lock the hard drive heads
if there's a hard drive. To do this: slide a coin or screwdriver
into the little slots on the sides of the machine to open the panels.
Once you've found the hard drive, there is one variety I can help
you with. In this one, there is a metal box to the right of the
motor, spindle, etc. On one side of this box is a single screw
which you have to remove. This will allow you to swing the metal box
out of the way on its hinges. Once done, you will find a white
plastic wheel on the bottom edge of the drive. TUrn it all the way
in the direction that it will turn. THere should be directions on the
metal box as well.

My .02 is why did they go with BNC? Eithernet would do as well with
F connectors and they are cheaper and easier to affix. I've done my

RCA and XLRs to name a few.

That's my understanding. There are three levels of BASIC for the Jr.
Level 1 is the ROM BASIC, level 2 is the disk BASIC and level 3 is the
cartridge BASIC. I was surprised that the cartridge BASIC was the most
complete but that's what the manual says.
