looking for a 7-track reel tape controller

[P Gebhardt]

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
