Should be the standard dual DSP card sold by supermac (Dual AT&T DSP16A's, board labled SCNB-1) which is just a private labeled Storm Technologies card.

The powercache card is cool, the only IIci accelerators I have found were 040 ones, there were quite a few 030 ones.

Also nice on the 3com ethernet card, not exactly a common one.

One of the things I would have liked to do was collect 020 and 030 upgrade boards for compacts, but those are getting very very hard to find, there was such a huge market for 3rd party upgrades back then and it all collapsed in the early 90's.
