sounds like a great idea.i have some early computer trainer hardware i am looking for info on.i have had some of it from when i was a teen.
all i run into is folks who want to buy it.as soon as they find all i want is info and its not for sale they clam up.

I have a NOS early 1970s digital clock that I bought on eBay a while back.

I have yet to find any information on it. It's a very unusual design, being one of the first solid-state digital clocks. It was made in Japan by Electer, but a Google search turns up nothing.

I have a Timeco Model No. 1 repeat cycle timer I got last month and I can't find any info anywhere on the web on it.

My Odyssey motorhome had essentially nothing available online. That was one reason I replaced it with a 1974 GMC; those have an amazing community of owners/supporters (online and in real life).

The Mini-Grip Gravidee toy motorized space monorail sets I owned when I was a kid have almost no documentation out there.

That "Doohickey" I have-The Specific Products Model WWVC Receiver has precious little on it as do the Nems-Clarke Special Communications Receivers Model 1302As... I DO have an operators' manual for the Specific Products-But its for a presumed later version than what I have.

I thought I wouldn't have a problem finding info on the Webster-Chicago Model 165-1A record changer I've had in the closet for about a year. Boy, was I wrong. I haven't found a thing for this model.

One electronics magazine that seems NOT to have been piped to the net--is ELECTRONIC-TECHNICIAN DEALER. I still have a lot of them...but would REALLY like to see them put on-line, like R.E., Popular electronics, E.W. and the PF reporter have been.

I wonder if they got a copyright block on some of this stuff like Youtube has with the videos.

Go to American Radio History website and he has alot of Mags and other goodies on there.

Try looking for info on a Semi Steel hand-cranked ratcheting drill press.

Try looking for information on old Utah Speakers, or better yet old Hammond clocks, (yes the same Hammond that later made the organs).

That magazine went through MANY name changes before ending up as ET/D. Many issues ARE available online at:

A Sansui receiver parts cross-reference. I'm hoping to refit my 661 with a blue dial scale.

Electronic parts, yes, Sansui made a cross reference from their part number to an EIAJ number, or a JEDEC number for some diodes (1N60, etc). Cabinet parts, no. Sansui and only Sansui distributed their parts, unlike Pioneer, Technics (Matsushita/Panasonic) and Sony. JVC was another - in the early days of JVC/Nivico, you had to call in the part, they'd Telex it to Japan, and you waited for the slow boat to come in. Thankfully their TVs used NEC components, so a Japanese-made Sears would have the part, and available through Sears parts.

Most cosmetic items varied by continent - get a Worldwide service manual, and you'll find all of the differences for Asia, Australia, South America, Europe and US Forces Europe units. Some parts weren't available in the US - patent infringement initially kept the parts unavailable. Wafer rotary switches were one - Oak and Mallory had patents on the "bend" of a contact, and the Alps parts infringed on the patent, so if you needed say, a rotary speaker switch for a US marketed unit, you could order the part from AAFEEs in Europe and they'd sell and mail it to you, but Sansui left you hanging, making the part unavailable to the US market. We went through this with a couple of units.

I no longer have the Olive-green covered Sansui guide, but have still have my two Sony Semiconductor part number/substitution guides - the base '86 one and the '88 supplement. After the internet came into being, Sony quit publishing the guide.

Abe Books had one of the Sansui guides for an astronomical amount back around 2004/2005, when a buddy in the DC area picked up a storage unit with about 20 Sansui Amps and Receivers and was looking for one. I haven't seen or heard of one since. Maybe someone has scanned it and is offering a PDF - I dunno..

HFE has your service manual....

Blue dial scale? Simply replace the smoky polycarbonate plate (#29) with a clear one, and replace the fuse lamps (#70) with blue ones, or get the blue LED versions.

I know the 7010 is the European equivalent of the 661 and has a blue dial scale, but I'm thinking it would be tough to find one.

Edit: Seems I can just get a 5050 0r 6060 dial and cut off a meter window, good enough.
