Ok, makes sense. I think using only 32K of RAM would be a simpler design. No jumpers to disable the on board RAM in blocks.
It is nice to be able to address other boards on the S-100 bus, perhaps someone has video cards they would like to run? Having a full 64K means we need jumpers if we are to add some flexibility. If we keep it as-is, then you can never access memory on the S-100 bus, since all the memory is on the single board (which is fine for my application at the museum but not so cool for others who might like to access other cards). :)J Date: Sun, 12 May 2013 10:01:30 -0700 Subject: Re: [N8VEM-S100:1651] IMSAI 8080 CPU card replacement From: laf...@lafleur.us To: n8vem...@googlegroups.com keep as much RAM as you can, 128Kx8 are just fine, its ok to not use it all.... keep it simple, do not over design it!On Sun, May 12, 2013 at 9:54 AM, John Monahan <mon...@vitasoft.org> wrote:
