Gary,
Sounds great! I have 3 Zeniths, so one or two will stay 'pure' while one of them will become my retro-dev-box 'O DOOM! :D (Goal is to run linux, or eventually write my own OS, but linux would be a great start - to be able to work in C using VIM. Because, well, it's VIM. On a phosphor monitor :D) Said machine will be the recipient of several of the Monahan cards, with the rest being used to build out my generic backplane/chasis/powersupply that I have stashed away. Though eventually I wish to turn that into an 'expansion' cage for the devBoxODoom(DBOD?) though I am not sure how easy it will be to create a 'jumper' to connect the backplanes. I also need to get much smarter about the power requirements, signalling, etc. I worry about speed and so on, how much noise/lag I would introduce - but my basic thought it to use maybe a couple of extender boards, with a pair of the edge connectors that get connnected via several ribbon cables, minus power traces. That way, I can make use of the second cages power supply to locally power the cards, without issues, and ONLY pass the signals back and forth. Not sure that this is even technically feasible, or if it does 'work' whether it will be useable after the added bus length, etc. Still, it's one of the ideas floating around my brain. I also wish to keep my compu-pro 'pure', card - wise, so that SD drive sounds like just the ticket. The system is already 'complete' though I think you may have been the one to identify it as a 'basic' system - bare necessities. Still, should be great fun. Enough rambling from me, I need to get back to work.
