Goodmorning,

- Does this projector incorporates at origin all the necessary upgrades to prevent owner from films scratching?

- Does PCOM "label" means it is possible to get projector directly plugged to a computer ?

- Is the "computerised" projector stage based on Motorola microprocessor or any other model ?
If yes, what about its reliability ?

(Processor reference or datasheet is welcome)

Thanks in advance

Phil

Phil, from this source, I understand it is based on a Motorola microprocessor : http://van-eck.net/itable.php?lang=en&size=0&cat=film&merk=52&type=GS%201200%20P%20Com

Thanks Dominique, what they wrote confirm Motorola chip installed.

Now , if I can get reference / type, I follow on investigation for more information (availability and programming process as necessary)

I don't believe the PCOM is any different as regards the guides to earlier machines. It would still need 1st and 2nd guide work. My suggestion is a metal guide for the first and a well-done two roller modification for the second.

How are Edwin's 2nd guides holding up, with the extra rollers?

Anyone tried using these yet for a lengthy period?

All i know from a very reliable source was that there was an early problem form Edwin's first version of the front guide, but cannot answer as to the later version, i'm not too sure i could trust any plastic type roller made up from any 3D printer as of yet no one knows how long this will last.

I thought the second version was quite recent? If so, it will take some owners quite a while to see how successful it is.

Plastic rollers certainly can be effective. My guides were modified by Dave Locke in the early 1990s and I've never had any scratching. He even dealt with the common Elmo running in reverse scratches, which I'd like to do in relation to my ST180!

I'm sure if the right type of plastic is put in the printer it should last as long as those formed from plastic any other way, like the Eumig ones.

From what I am seeing myself from the parts that I've had from Edwin, I don't concern myself with their durability or longevity for that matter, but for parts coming directly in contact with our films surfaces, I'd want to see the surface texture much finer than the cam parts or the spindle parts I've had from him myself,very kindly.

If this can be achieved, I wouldn't foresee an issue myself versus an original or an original modified spare.

One thing I can categorically confirm is, they are made to very fine tolerances so the accuracy of these parts appears to me to be superb.

Of course until put to the test for a very long time, no one can say for sure how long they would expect these to last for without doing some scientific tests on them for hardness etc:)
