Fascinating hi-tech/old-tech mix.
I am currently gathering the parts to build a 1979 vintage Acorn System 1 (http://speleotrove.com/acorn/index.html http://speleotrove.com/acorn/index.html). I was aiming to use the original chips, although I am struggling to find the IO/RAM INS8154 at a comfortable price - I am currently working my way through some online stores that specialise in old stock without much success. If anyone has a tube of them they no longer want taking up shelf space...!?
Plan B will be to redesign the I/O interface.
Plan C will be to emulate the whole lot in a PIC Microcontroller (including the 6502).
