Hasselblad PCP 80 projectors for slide show?

[Alexander6x6]

I found several PCP80 projectors for sale that were probably used for slide shows.
Does anyone know the name of thehardware generally used for this purpose?

Not really, but you can glean some hints from here:

Hasselblad PCP-80 PCP80 Slide Projector - KX Camera Kodak Slide Projectors Since 1980 - 1732-1/2 Grand Ave. Santa Barbara, CA 93103 805-963-5625

Seems to me there are a few 'tiers' of 'fanciness' in using multiple projectors together:
* Manual operation using a remote control unit, possibly with a dissolve function
* Basic automated operation with a rudimentary programmable control unit that e.g. alternates between both projectors
* Fancy custom automation using a computer of some sort and a digital interface between the computer and the projectors.
There's a thread here on Photrio that was last active only a few years ago that featured someone who got a couple of Kodak carousel projectors (IIRC) to work together, I believe even using some kind of computer control - so that would be the 3rd option on the list above. Sadly, I can't find that thread ATM.
Given the notes on equipment listed on the kxcamera website it seems that the interfacing was at least to an extent standardized and some of the misc stuff that would work with Kodak projectors might also work with the Hasselblads, perhaps after adding the required interface to the latter.

Interesting, thanks! The PCP80 projectors have Kodak connectors.

Once I had Stumpfl but never succeeded to create something reasonable. Using the computer connection would be much easier for me.

There are some used Hassy projector systems for sale with multiple (two, or more) projectors in a stack. While Hasselblad did not officially offer an accessory multi-projector support kit for sale, the projector design seemed to be ready to support such use. It has been all too many years (over 30) but I seem to recall seeing a presentation by Ernst Wildi (as an official promoter of Hassy) with two PCP80 prejectors synchronized.

Here's the thread about my adventures synchronising three Kodak Ektapro projectors. I'm still doing shows with this rig:

Multi-Image in 2020

I am influenced by Michael Firstlight's post here. Multi-image is a term used to describe a forgotten photographic industry supporting multiple projection and sound presentations. As the industry progressed in the 1980s some very complex slide shows became possible using often more than 50...

It looks like the PCP 80 has DIN connectors. The Ektapros I work with have RS232 which makes linking them to a PC not too hard. Unsure about DIN though. You might need to work with older multi image computers from firms like AVL or Dataton. Dataton in particular because they were also Swedish.

Here's an interesting (expensive!) auction showing three PCPs rigged up with an AVL Fox:

I appreciate it, thank you a lot! Now I am totally fascinated and depressed in the same time.

It seems to be different types of connection for PCP80:

This is extremely expensive indeed!

Manually programming with this unit takes quite a lot of time. The PC software would be much better.

I'm using a little program called EktaproGUI which is a Python script using the Kodak P-Bus language for the Ektapro projectors. There's good documentation on the language from some Kodak publications. It looks like the PCP does not have a native language but rather accepts traditional controllers through the DIN.

here you can see the connector types for PCP80:

 

[perkeleellinen]

There's very little online about these. It seems the 70523 is standard, the 70524 allows for greater connectivity and the 70525 is a seven pin connector for the US market.

The documentation talks about allowing 'certain' control systems but no more.

You could try contacting KxCamera for advice. They have an auction of a 70524 here:

What connector is on the back of yours?

 

[perkeleellinen]

I suppose you could buy a 12 pin - USB cable and then run a command through terminal and see if anything comes back.

The one I have doesn't have a connector. The second one that I can purchase has the same connector as you mentioned (it is also marked as "A/A")

 

[perkeleellinen]

It sounds like you might need to buy a 12 pin connector which don't seem cheap.

Just found this link from 12 years ago which suggests the 8 pin connector can be used for dissolves and remote control (also on page 20-21 in the manual):

https://www.photo.net/forums/topic/469243-hasselblad-pcp-80-projector-7-pin-connector/

I think that connector is DIN 45326 (hirschmann mab 8), maybe you can find a cable that goes DIN - USB

Page 21 is most valuable, as it contains pinouts to potentially control all projector functions. The optional control modules appear to be adapters providing plug-in compatibility to various legacy control systems, and the correct one to pick may depend on which control system the OP wishes to use. Custom or homebrew solutions could skip these entirely, in favor of J13 and J14, which are standard on all projectors. I imagine that the modern solution could involve inexpensive microcontrollers such as Arduino. It would be very handy if any of those optional modules provided RS232/RS422 serial data, but I doubt it.
