That makes sense. What kind of NRE costs did you have? I don't mean amounts, I just mean what kinds of things did you have to do in the project. In other words, if you feel like it, tell us a little about what you did and how you went about it. >>I read with interest the various attempts to get an ethernet >>card, video card and CPU upgrade into the case.

Sounds like it's worth a try with these adapters then. In the long run, I may need to find one of the 68030 upgrades. There were several revisions of the Turbo 040, with the later revision removing a bunch of PLDs, replacing them wiht one big custom IC and moving the cache from teh daughter card to the main card. Is it definite that the Turbo 040 does not work with the Xceed card, or is it possible that some revision may work? >>One is a SuperMac "Dual PDS Adapter".

But for which Mac was the "SuperMac 'Dual PDS >Adapter'" designed for? I don't know for certain. This was another find from teh bins at Goodwill. I believe it is a IIsi/SE30 card because it has a 68 pin PLCC socket probably for a FPU. The only relevant writing on the card is "SuperMac 1991", "Dual PDS Adapter", and ASSY 0007527-0001 REV. B". There is a metal plate backing up the circuit card, perhaps to give it extra rigidity. >One way to avoid doing that is to install the IIsi adapter on top of an >Asante ethernet card that has the PDS passthrough connector... Is the Asante ethernet card the preferred card for these projects? If so, what are the advantages of that card. I like Asante, so I'm perfectly happy to seek out the Asante card. I'm just curious about the reasons for the choices folks have made. > >>Last question group. Has it been confirmed that the IIfx ROM will >>work in the SE/30? Does it work well?

You have much very cool stuff on your web site. It was from your web site that I determined this was an SE/30 ROM in the first place. I knew I had a ROM to an old machine, probably a II series, since the ROM was generally soldered down after that, but I didn't know what machine it is for until LEM led me to your site yesterday. Anyway, the numbers on the chips on this ROM are 342S0651-A through 342S0654-S. According to the Apple Document that your site links to on ROM sizes, the SE/30 ROM is 256K. My IIci's ROMs are 342-0733 through 342-0736. I was thinking I might pick up another IIci motherboard, desolder the DIP chips, read out the contents, write them into some PLCC EEPROMs or Flash and put those on the SE/30 ROM SIMM. The IIci was the first 32 bit clean machine wasn't it? I would expect its ROM to be the closest to the SE/30 ROM, though it may not be different enough from the IIsi to matter. The IIsi is basically the same machine as the IIci as far as I can tell. Thank you for the answers and information. Jeff Walther -- Compact Macs is sponsored by <http://lowendmac.com/>.
