The BYWOOD SCRUMPI preservation site 

The SCRUMPI was the very first single board home computer kit made in the UK. It launched at the end of 1976 from Bywood Electronics.  Making use of the National Semiconductor Simple Cost-effective Micro Processor (SC/MP) chip known as SCAMP.  Unfortunately the designer of the SCRUMPI tragically died young, which stopped its development.  A well written background to the system and more importantly to the man John Miller-Kirkpatrick (August 1946 – December 1978) written by Tony Smith can be found on The Register

The SCRUMPI I, II and 3

With 256 bytes of RAM and only a handful of chips with 16 switches and 24 LED lamps the SCRUMPI was not an advanced computer…

A significantly upgraded one, the SCRUMPI II that had an EPROM was designed by Mark Phillips and marketed by BYWOOD in late 1977.

In May 1978 they started shipping the SCRUMPI 3 with TV out and ASCII keyboard with a tape and Vero 502 case option.

There were plans for a SCRUMPI 4 based on the new single chip NIBL (BASIC) ROM that would use a terminal – like a SCRUMPI 3 but, sadly JMK passed away before it was launched

What is this site all about?

Saving a bit of history

A unique piece of history that is at risk of being lost as we are only aware of one or two each of the first and second models worldwide. The SCRUMPI 3 is lost as far as we are aware… but, Paul Robson has created an emulator that allows you to experience it working.

We are not sure a working version 4 existed but, the modern Karen Orton PICL project (a two chip design) is probably close to what was intended

Who we are

As a few electronics and computing enthusiasts we are determined through the creation of modern clones to ensure that these devices and their history can be preserved in a museum setting while also allowing people to create and explore one for themselves.

Help needed

Please let us know if you have anything to add to the preservation effort.
