Hello list, I have been looking for years for a q-bus or unibus-based disk controller that is able to handle 7-track drives (NRZI encoding). So far, I only located one controller type which handles that: Dilog DQ120 or DU120 and I never came across any. Any other suggestions regarding controller types?Contact me off-list if you are happy to part any 7-track tape controller with me. That would be very much appreciated :) Best regards,Pierre -----------------------------------------------------------------------------http://www.digitalheritage.de
