That is a great find, I'm glad the card is working even though software is not correctly reporting the CPU speed! Some diagnostic software can be a bit finicky with accelerators.
I bought this small heatsink/fan combo for my IIsi (Amazon link), it is designed for a Raspberry Pi. I haven't installed it yet, but it looks like it might be a good solution.
In case anyone runs across this old thread, here is a link to an article on the MonsterMac from the May 1986 issue of Apple User (link), page 16. It discusses the installation process, starting with a 128k -> 512k RAM upgrade, and then adding the MonsterMac board to bring the total to 2mb.
I found this article on the MonsterMac upgrade in the May 1986 issue of Apple User (link), page 16. I always think it's interesting to read old articles about products that were new at the time.
I've never been able to bring myself to use the twist method, though many people swear by it, with few horror stories. If I'm not using hot air I generally use a pair of side cutters to cut the can off the base, as close to the base as I can get. I do this while applying downward pressure on the...
Everybody has done it, usually more than once. It's part of the hobby, and especially part of learning. There aren't very many ways to damage one of these boards that can't be fixed.
Now it's time to put your soldering skills to the test and build one of Bolle's reproduction Performer '030 accelerators!
Congrats on getting things (mostly) working.
Keep us updated in the IIsi. As the owner of two, and repairer of both, I'm always interest in people's IIsi challenges. Hopefully a simple recap will bring yours back to life, though in general it seems IIsi's take a bit more than that.
I'm not aware of any sort of combination video/Ethernet card. There were some dual-PDS risers that would let you run two PDS cards, but I don't think there was a version with dual NuBus or PDS and NuBus.
The newest BlueSCSI has WiFi, that would be an option to get your machine connected without...
