Qudos MINICHIP / Quickchip ECAD and Ferranti ULA docs

In my long-running tradition of obscure requests... Does anyone know if a copy of the Qudos Ltd "MINICHIP" gate array design tool still exists anywhere? This was a CAD tool designed for the BBC Micro (with 6502 Second Processor) which allowed the machine to be used for the design of Ferranti ULA gate arrays. There was also a similar tool called "Quickchip" for the Acorn Archimedes ("A440 only" according to page 22 of this: http://acorn.chriswhy.co.uk/docs/Acorn/Brochures/Acorn_APP155_HardwareExpan… ) There's some mention of MINICHIP here: http://www.chilton-computing.org.uk/inf/literature/newsletters//ecn01-20/p0… http://books.google.co.uk/books?id=GzPpAAAAIAAJ&lpg=PA85&ots=sR_gUY… I'm also interested in a copy of any documentation on Ferranti ULAs - databooks, details on the logic cells (specifically the ULA9C series but ULA5C may also be useful), design software (or documentation thereof) and so on. Examples: Qudos Ltd. - Qudos Logic Array Design Software Manual QED2 (pub. 1986) Ferranti - Ferranti ULA Design Manual A/F002 (pub. 1981) Guessing what I'm trying to do is left as an exercise to the reader... but it involves photos of the Tube ULA layer masks and a copy of Degate... :P Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/
