I've got an old retinal camera that attaches to a peripheral device (laptop or monitor) using the connector shown on the webpage below. Is there a name for it and are there adapters that allow it to connect to newer devices.

Any help is greatly appreciated!

It sure looks like #7 in the diagram you provided. It does appear to have 68 pins.

Is it a Topcon TRC-NW6S? It looks like the photography data output terminal cable was different depending on the recording equipment used. The manual just states

"When using a TOPCON IMAGEnet system, connect the photography data cable (optional) to the photography data output terminal of the instrument.

Note: Various types of connection cables are available for connecting the instrument with external recording devices. For details about connecting external recording devices, contact your dealer or TOPCON (see the back cover)."

So you might need to find some original documentation to see what it was meant to hook in to.

I count 68 pins as far as I can tell from the blurry photo, an old parallel SCSI data cable would be my best guess as those had 68 pins. Could be anything from fast wide SCSI to Ultra-320 SCSI as they all could have used that connector. Dates to around 1994 at the earliest if it is a SCSI connector. I'm not familiar enough with SCSI to answer if the newer parallel SCSI variants are backwards compatible with the older ones, so I can't say if that could be made to work with modern hardware.

You're spot on, Azaran. Unfortunately, I bought the camera second hand, and Topcon doesn't offer any assistance unless you bought from them, which is understandable, but they don't even provide online resources that would benefit others. They keep all the info close to the vest, and though I have the PDF you referred to, it doesn't go into the level of detail I need.

It looks like people are using adapter kits to use modern DSLR cameras with the equipment. If you're trying to get it running you may have a better time with that than trying to resurrect SCSI connections and their proprietary software/imaging set.

Exactly. I've got the Nikon camera's hot shoe connected to the retinal camera, but that connection is 'spliced' into the rest of that wiring, so I figured it might be needed for the overall function of the equipment. What I don't have is the shutter connection that syncs the Nikon to the retinal camera.

That's what I'm afraid of. Thanks for the additional info.

Thanks, Azaran. Do you know if the SCSI connection can be converted to plug into the back of a laptop? I see converters for 50 pin to 68 pin, but not from 68 pin to USB or other interface.

It's been a very long time since I've had to deal with adapting SCSI connection to other connections. There are SCSI to USB adapters out there, but you'd need to find one with either the correct type of SCSI or sort out if you can daisy chain adapters to make it work. And even then, it's a maybe at best to make it work. The adapters don't tend to be expensive so it might be worth a shot.
