I am pretty sure it was 100 six-bit characters plus a parity bit and a stop bit, so the recorded character was indeed 1 byte but to say it was 100 bytes that would be like adding the formatting, ECC and header to the 512 or 4 KiB industry standard sector.

They might not have been multiples of 128? Long, long ago, I was told 100 bytes per sector?
