Manuals and documentation


A7000+ Odyssey

This is one of the post Acorn A7000+s made by Castle, the CTLnnnnnnn serial number is a bit of a giveaway! I bought this computer from IFEL in August 2002. and upgraded it with an extra 64MB. It is the only one I have that run RISC OS 3.71. It has a 56MHz ARM7500FE and is comparable to the Microdigital Mico and RiscStation R7500. Although it does not have the expansion potential of either the Mico or R7500, it does not lose out as virtually no upgrades/add-ins have been produced for those computers.
Here are some pictures:
