My system had this card in the 80s. It was definitely one of the lesser used accessories. Three floppy drives? Used all the time. Two printers? Yup, dot matrix one used for draft and the Brother daisy wheel with rs232 controlled used for higher quality output. Speech synthesizer used for games and gimmicks. Extra RAM used as extra RAM always is.
Tape drive used rarely. P-Code card used hardly ever.
