Our Spectrum Management Agency (or whatever it's called this week) has a less enduser friendly attitude towards dipsticks in fringe areas that think they should be able to watch marginal signals on "rabbit ears" inside a substantial building. It amounts to "Get an outdoor antenna." No outdoor antenna, no valid grounds for complaint. There are no specific regs regarding emf emission >from computers, they have put the onus on the RECEIVER manufacturer to ensure adequate filtering & shielding from unwanted signals. The CB fad of the 70's was a direct cause of this, after it was discovered that perfectly functional CB's would drive certain televisions berserk because of stupid choices of IF frequencies (Amongst other "They did WHAT!" type design, um, features.) If you have a properly installed external antenna (Yagi of some kind - cut for the channels you are trying to receive) and proper coax feed into the set, and you are STILL getting interference, only then will they look into it. This attitude has cured enormous numbers of problems. Cheers Geoff Roberts Computer Systems Manager Saint Marks College Port Pirie, South Australia geoffrob(a)stmarks.pp.catholic.edu.au

Tek 4051 and 4907

by Innfogra＠aol.com

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. Paxton

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.

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. Les

Hi Joe, 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..?

KIM/MOS-Tech

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.

85mb Micropolis in a Microvax II?

by CLASSICCMP＠trailing-edge.com

>doable but, near unimplementable do to the lack of Qbus. The more common >situation is unsupported, IE: DEC didn't consider it marketable or test >it exactly that way. Two RDxx disks in a ba123 is an example. 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.
