Hi,
Damn, I wish I could help with your enquiry but I live in the UK so, sending cables to the USA would be too expensive for you.
I sell the 96 way DL connectors (to distributors and studios in the UK and Europe) and have cable plus the 25 way D connectors in stock but, I feel the pricing for those of you in the USA would be prohibitive. I also have all the SSL pinouts as well, after having worked there for seven years (1980-87) but beware that they did change over the years.
I have just completed some DL to 25 way D connectors for someone else on here which were 6 metres long. I could construct some for you or others far away from the UK but, what I may suggest is that they could be 1 metre long (about 3 feet) which would save shipping costs for the cable. Hear me out on this ...
By having a 24 or 32 channel DL wired to 3 or 4 x 25 way D connectors at 1m long, you could then buy 25 - 25 way D looms locally to extend them to your required length. Just a thought and get in contact directly if you feel that this could be an option for you. My website and Facebook details are shown below.
