Audio in/out support in original Lisa vs Lisa 2

Hi all,

Am I correct in understanding that the original Lisa had audio jacks (mic input and line output) while in Lisa 2 there are no audio connections?

No, I don't think that is

No, I don't think that is correct. As far as I understand it, all versions of the Lisa had the same audio capabilities (similar to other "business class computers" of the time like the IBM PC), which generated a programmable pitch on a single channel, output only. The sound is produced from an internal speaker and there are no audio interface jacks. There was a rare option card called the "LisaDAC" that emulated the audio capabilities of a Macintosh for use with the MacWorks environment.

See the information collected here.

Note that the Lisa was still

Note that the Lisa was still under development for 18 months after that was written. In the more recent September 7 1982 version of the Lisa Hardware Manual, the description of digital audio I/O was removed.
