DescriptionAcorn EASI Bus Test board (top).jpg |
English: Acorn EASI Bus Test board (top).I bought these 3 boards from CJE Micros in November 2009. I was told that the had come from Acorn via Castle and were sold to CJE Micros as part of a clearance once manufacture of Risc PC has ended. They appear to be Acorn test equipment to diagnose p[roblems in Risc PCs. How they work or what exactly they do I have no idea, so if anyone knows about them or used them at Acorn I would love to know more...
The board is marked EASI BUS TEST 0197,204 Iss. B and has serial number 9520/004. The Acorn Expansion bus enabled expansion cards (a.k.a. podules) to be attached to Acorn computers from the Archimedes to the A7000. The Acorn Extended Address Space Interface (EASI) is part of the DMA Extended Bus Interface (DEBI) in a Risc PC. This defined the interface for expansion cards to communicate with the computer (see Acorn Enhanced Expansion Card Specification for the details). |
