Not much of a hack, eh? These are supposed to install in minutes...
I bought my Stealth port off of a guy on eBay months ago for a decent price. Held off on installing it because I had no internal modem cable. I thought I'd need to find an OEM Apple modem with cage and cable - only to shelf the modem board forever. Found "welovemacs.com", from whom I bought an empty cage and cables set for $10, so I'm psyched.
Until I try to install it! The serial port header and connector were so wide that, when connected, the case could not close (both halves are needed). I needed to use snips on the back end so the port would fit flush, and needed to fold two metal tabs aside. For the Stealth PCB I needed to desolder the pin header, and solder the cable wires directly to the PCB. It took a lot of fidgeting.
Now it works perfectly, my B&W sending MIDI for the first time! I know that the modem cage is the Apple part number for their OEM B&W modem… I am guessing that maybe I really bought from the guy a G4 Stealth port? Anyway, it did not fit, but with some patience I made it fit. Ack!
