The ROM Box from Micro Pulse is a peripheral which enables you to access up to 11 ROMs. However, not all the eight resident ROMs can be on-line at once –there is a switch enabling only one to be selected at a time. The ROM Box connects to the BBC Micro by a 28-way ribbon cable and an easily detachable edge connector. The 28 DIL header to the cable simply plugs into one of the empty sideways ROM sockets between the OS 1.2 and the Basic chips, then the short (290mm) cable is clamped when the computer's lid is replaced. There is also a high quality ZIF socket (position number 5 in the box), allowing easy and safe changing of ROMs. Another feature is the red LEDs to indicate the current ROM. The fact that ROMs are isolated means ROM interaction problems associated with internal boards are avoided. Information is taken from a review from Acorn User, September 1985.
