Torch Z80 second processor by Lee Davison
[Back]

The Torch Z80 second processor.

This is a second processor board for the BBC Micro. Apart form the board itself I have no information on this board. While there seems to be information available for the Acorn Z80 board any data on this board seems to be lacking. I would like at least to get the circuit diagram for it. So, if you have further information, or know where such can be found please e-mail me [e-mail].

Just for now there are a couple of larger images and a dump of the 2764 8k EPROM.

  • A 640 x 480 jpeg image.
  • A 1024 x 768 jpeg image.

    I seem to have two versions of the EPROM so both are available.

  • Download the EPROM 0.94 as an Intel hex file.
  • Download the EPROM 0.94 as a binary dump.

  • Download the EPROM 1.02 as an Intel hex file.
  • Download the EPROM 1.02 as a binary dump.

    • e-mail me [e-mail]
