My interest in the RTC card stems from a need to have a reliable, high resolution periodic interrupt in one of my probable applications. It doesn't matter if it's from the system crystal or from the line frequency as long as it's there. I don't recall if there were other cards that generated periodic interrupts; perhaps the disk controller?
I'd like to hear from anyone who has gotten one of the new, super combo S-100 cards (64 KB RAM, flash, disk emulator, I/O). Do these actually exist yet? If so, do they work? If such are available, then that would strongly influence the ordering and use of other cards. And if they can generate a high resolution periodic interrupt, then so much the better.
