Thread: Original Blue PET "Sanyo" cassette deck white buttons - model number?

  1. #1

    Default Original Blue PET "Sanyo" cassette deck white buttons - model number?

    Supposedly this was a generic shoebox-type tape recorder.

    Was this design ever used on a standard cassette deck?

    I've seen it said these were Sanyo units with the power section removed, but I've never seen a Sanyo-branded one that looks the same.

    I'd like this version for my PET but I've never ever seen one for sale unless already attached to a Blue bezel PET. Even a regular consumer, if it existed, would be fine for me, as it's really the aesthetics I'm after rather than usability.

    It most likely was a retail item as is, somewhere. There were(are) a lot of things sold in foreign markets that most people wouldn't ever see.
    Be polite and I may let you live.

    Dumb question I guess, but are you looking for a tape deck that would be an authentic accessory for a PET without a built-in tape deck? In which case it appears that the earliest (common?) external Commodore datasette drive was a black version of this recorder:

    http://commons.wikimedia.org/wiki/Fi...asette_c2n.jpg

    which is visually a lot different from the one built into the Blue pets. (The same deck was used internally on the other 2001s.) Does anyone have a picture of an external version of this deck being used with a 2001? (Does the version of BASIC on the 2001 actually support dual decks, for that matter?*)

    Doing a Google image search for "Sanyo portable cassette deck 1976" netted this auction for a "Strauss CT-1020":

    http://www.ebay.com/itm/Vintage-STRA...-/271672446856

    That sure looks like it's the same chassis as the Blue PET one. (With different labeling, obviously.) Although visually further removed I sort of wonder if the Radio Shack CTR-34 is the same mechanism with a different top case casting, as the button spacing and the audio port area under the handle look identical. Perhaps Sanyo is the OEM for all of them.

    Of course, unless you cook up an adapter a normal tape deck isn't going to do a whole lot of good for your PET. But I'm sure you know that.

    * Edit: answered my own question there but on the other matter... the oldest Commodore brochure I could find a picture of shows a 2001 with white keys connected to an external deck with black keys in the style of the later Datasette. Certainly doesn't rule out they sold the white key deck seperately, of course.

    Thanks for your interesting response. In actual fact, my desire for the older one is to install it internally and purely aesthetic - I have a PET that is virtually down to bare metal, requires respray, etc. Since it doesn't have labels, and I'll be getting new metallic label printed, I want to kit it out with the earlier blue design because I like that design but can never find (or afford) one. I would be quite happy with one that looks the part even if it's not usable with the PET.

    The Realistic and Strauss models you linked to bear a remarkable similarity to the original PET deck, and are closer than anything I'd seen on my own fruitless searches. Thanks for that, it really helps to narrow it down.

    I have a PET 2001-8 that appears to have had a standard early model Commodore C2N fitted in place of the original deck. There are some pictures of it in this thread: http://www.vintage-computer.com/vcfo...or-restoration

    Honestly I'd be pretty skeptical of a claim that *all* "Blue Pets" came with the same white-key'ed tape deck. As has been discussed in a number of places Commodore seems to have been pretty liberal with mixing-and-matching parts when churning out PETs, and while it may be true that "most" PETs with a blue screen bezel came with that white-key'ed tape deck it wouldn't surprise me at all if a few units snuck out of the factory with the black deck.

    Just as a sort of not-very-interesting update... I discovered they were also sold in Brazil under the brand CCE (who are still going)

    Following ad is from 1973:

    New info regarding this drive.
    I recently acquired a "white keys" Commodore cassette drive as well as an audio recorder which is mechanically identical.
    I noticed right away that they are also mechanically identical to the C2N drive and likely all made by the same OEM.

    The audio recorder is a Precor model C-1800 R. Apart from the different color plastic, it is physically and mechanically identical.
    Like the C2N, it is also marked as made in Taiwan. The circuit board has the part number CT-1030 instead of CT-1020.
    Like the Commodore drives, the tape transport mechanism is stamped with the name Musashino who probably made the transport assembly or at least some parts of it.

    Photos are here... https://photos.app.goo.gl/ViuRcRk1f3fKWDbKA
    Photos are still being updated so check back. YouTube videos will be coming soon.

    Once I finish documenting everything, this audio recorder will make a great source for spare parts.

    Regarding the Sanyo drive ..
    The white keys drive was not made by Sanyo. Commodore used an off the shelf Sanyo recorder on the first units produced in October of '77. Probably because they didn't have the planned cassette drive yet and needed something to start shipping units because they were way behind schedule. The white keys drive was installed in units starting in December of '77.
    I made a video about the Sanyo drive on my YT channel here... https://youtu.be/xzMdKCOOvKI

    Regarding the "blue screen" with the "white keys", I believe that is accurate. A google photo search for the PET 2001-8 will show that nearly every PET with a blue screen bezel will have a cassette drive with white keys.
    Anything is possible of course and you can find photos of at least one blue screen with a black C2N drive but it's possible parts were replaced during restoration.
    From what I have seen, Commodore switched to the blue screen bezel around the same time they switched to the white keys drive and switched back to the black screen bezel around the same time they switched to the C2N drive.

    Also, if you haven't seen it, Giacomo Vernoni created a great booklet on the history of Commodore tape recorders. It's the best reference I've seen on all of the different variants.

    I finished a video on the "generic shoebox-type tape recorder" equivalent of the "white keys" version of the PET 2001 integrated cassette drive.

    The one I have is a Precor model C-1800 R, but there are several other possible brands that might be the same mechanism.
    Some are marked made in Taiwan and some say made in Japan but these all appear to be the same, at least externally.
    Avenger TR-303
    DHC CT-1020
    CCE Transicorder CT-1020
    Strauss CT-1020
    Futura CT-1020

    Apart from the Precor model I have, I have never seen any confirmation that the internal mechanisms of any other models are the same.
    A photo I saw of the Avenger TR-303 internals showed that it is mechanically different but similar. Perhaps an earlier revision of the mechanism.
