This is my Mac 512Ke from 1986. Floppy disks (at least working ones) are getting harder to come by, so I'm booting from a Floppy Emu that is emulating a HD20 hard drive. The Mac is connected to a Pakratt PK-232MBX of the same vintage. I built a cable to connect the modem to my much more modern Icom IC-7600. I've only just scratched the surface of the capabilities of this setup, but it's at least working so I'm excited to try some more.
