Wow. I have even less time to reply this evening, and there's more material.
Yes, I'm thinking simpler, so the various expansion chassis are not today's project. Also, I'm a bit of a purist. I want the base SE/30 unit to fit in one self-contained box, not move out into additional boxes.
Cabling schemes direct to the 68030 socket would seriously limit the audience for the upgrade because of the inability to put the machine back to stock, which is useful for many reasons.
Yes, my writing was intended to convey that the Turbo040 or PowerCache would block the cable connector, not just the upgrade adapter.
TylerEss, I would deeply appreciate it if you take a second look at the geometry and share your thoughts/conclusions.
Wally, thank you for the part numbers. I'll look into the possibility of covering/plugging into the analog/digital cable connector. Molex is generally kind about sending out samples. However, I'm concerned that the mated connectors may stick up considerably higher than the motherboard connector alone does. That may ditch that idea.
Um, 3 X 40 pin cables should do the trick. There are a number of ground and power pins which could be omitted and replaced with low gauge wire between the two boards. The issue with the Ultra-ATA cabling is that some number (seven?) of those 40 pins are connected to ground, and I don't know if that's at the designer's discretion or built into the crimp-on connector, which also grounds the *extra* 40 conductors. If it's built in then that would reduce the available conductors to 99, which may be too few.
Thanks for the interesting info Fogwalker. A multifunction card is in my dreams, but not in my near term plans. Although I have been known to bid on interesting lots of SRAM and GRAM on Ebay thinking, "This would work nicely as VRAM on an SE/30 video card."
Finally, I have picked up a few hundred sockets for the SE/30. It's less than ideal, but I figured I could offer some kind of socket installing service to folks who want to purchase an adapter, but have a soldered down 68030.
I don't know how common the older model of Turbo040 is, but I have a few of them myself. I would like to make the cache equipped model fit, but it may not be possible.
