Good morning, FurCafe;
Congratulations on getting the question of the focus assist light sorted out. Also congratulations on having a Minolta camera that is not common. The TC-1 is a bit unusual.
It is amazing what can be done with the proper documentation in hand. It really does help with operating the equipment. In other areas, having the owner's manual with you may be the only way that you can figure out the necessary key stroke sequence to get through all of the menus to reach the parameter you need to adjust. This afflicts not only cameras, but also cellular telephones, radios, televisions, small computers, microwave ovens, et cetera.
In this realm, I am also trying to set up equipment to more easily convert many of the older photographic equipment owner's manuals, user's guides, and similar publications that I have, into forms that can be conveniently stored and transmitted over the internet for other owners and users. One of the losses I experienced was that of the in-depth technical information for an early computer that I still have. I have not been able to replace it as it was information normally used only by the dealers. I want to prevent this kind of a similar loss with the information I have available on my cameras and accessories for other owners and users.
