Awesome! i loved those things. I used to have one. Try to find the floppy drive (and accompanying disk) that gives you 100KB floppy storage on a modern floppy. The floppy also ru…
As far as I know, the first Mac to actually have DMA (which the very first IBM PC had) was the IIfx and it was only used under A/UX.

I was very lucky, but it goes to show how proprietary RAM modules - must have some "play" in them to be mass produced for slightly different computers. So that's another unique th…

Great news - I was able to hack my 3400 128MB module to work on the Kanga!
It surprised me that the 3400 128MB module didn't work - considering that the 32MB Apple module worked…

I suppose that, with 512MB, you could run…
