Found the CAMAC cables--there are lots out there, but the company that makes/made them for ML is still out there; however, they only distribute commercially, so you talk to the guy with Fischer, who refers you to one of his distributors, who adds it to one of his retailer's order, who bills you and then they are drop-shipped (from the manufacturer). Should have them next week.
Next project--contacting ML to see about a total tune-up/servicing. Because of the potential value of these pieces in "perfect" working order, I am considering "biting the bullet" and having the the pros go over them before I do any (expensive) damage by trying to use them blind after sitting for so long.
BTW--does anyone know a reputable local business that does good re-foam work? The kits for the DQ-10s are readily available, but I would never attempt to work on these. The only re-foams I have ever had done were some Infinitys that I sent to California.
