Things are tough right now ...

They're tough for everyone :( But when coronavirus hit here in the UK, the museum had to close its doors to the public, and we lost practically all our income overnight.

Please Donate Via Just GivingNo visitors, no workshops, no events, no school visits... no income. We know that things are tough for everyone right now, but if you can afford to help us through these tough times please donate what you can.

Stay safe, stay at home! There's over 36,000 exhibits here! That should keep you occupied for a bit - get searching!

Micro Pulse ROM Box

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.
