I'm currently preparing for my next service and repair project and am researching the Canon A-1, the direct predecessor of the Canon T90. Fortunately there are more articles and videos available on the A-1 than on the T90.
Crucial for my own work is that there is also an article about the Canon A-1 in the
SPT Journal, a C & C Guide and a comprehensive
Canon Service Manual with lots of detailed information.
I found a tutorial from a Japanese colleague for service, including removing the mirror box. I was able to follow along easily using the translation function in my iPhone's Safari browser.
I also really like the author's article on disassembling and
cleaning the shutter of a Canon T90.
