I have some excellent news to announce: I have perfected the code for displaying pics of the Macs, and finally figured out how to up the color depth (was at 8-bit, now 16-bit). Disconcerting is that the time taken opening cars seems to have nosedived - previously it was nearly instantaneous, now it takes a full second to switch cards. Now, I'm on a well-upgraded LC 575 - I hesitate to estimate the performance hits on, say, a base Mac II. This is all due to the behind-the-scenes preprocessing needed to write to the color framebuffer. I have improved the speed a bit (by moving the code from card script to background script); a solution is in the works.
