Applied Engineering DataLink LC: Multifunction PDS Card for Mac LC
For fans of Applied Engineering products, this is my DataLink LC. This board combined an internal 2400bps modem, an FPU socket, and an extra serial port for the Mac LC's valuable single PDS.
This one appears to have the V.42bis upgrade allowing the model to achieve 9600bps. It also has the FPU/math co-processor socket populated with a Motorola MC68882FN16A. Missing is one of the two plastic standoff pegs, but I think I can make one.
I don't have any software or manuals, and I can't find much info on this model. I was able to find some brochure scans at https://ae.applearchives.com/mac/datalink-lc/ but that page isn't linked from that awesome site's main page.
I don't yet have a Mac LC, but I'll pick one up when I have the time to do a recap. Anyway, I loved AE's Apple II product line back in the day and I thought I'd share this one from their lesser-known Mac catalog.
