RE: [N8VEM-S100:1238] S-100 board reorders

There's a RAM board available???  Damn, Why am I always the last to hear about these things?

Well, there's no point in it for me now.  I'm looking to resurrect the original RAM boards.

But for Todd, that's definitely the way to go!

I'm interested in building a simple 64K RAM board for

multiple RAM card(s) with many memory chips.

If someone could point me to a schematic, I'd
like to build a few.  I know Don Caprio mentioned
earlier this year he had a project on the PBworks
page but I don't know where to find it.

I'd like to look at a few designs.

Hi Andrew,

Cool, thanks! Just a note on what I'm using the first (buffered) prototyping board for....
It's currently being used as a 64K RAM card in my IMSAI. This was done to establish a working system. I'll be replacing this RAM card with the old RAM cards when I test/fix them.
At that point, I'll repurpose this card to be an 8080 CPU, RAM & I/O card for another IMSAI system I'd like to resurrect.
