yeah, i recall the ZXCF not really saving me much money in the end, but i'm not unhappy with it.
i wasnt prepared to make a divide kit at the time.
the divide offered in the UK was a divide+ and not only was it expensive but it was also on a loooooooooong waiting list.
i do think there is a similar device on the cpc and i remember that being both rare and expensive too. keep me posted if you find anything interesting, my cpc 6128+ needs much love
