The Macintosh Plus was the first real improvement on the Macintosh 128 (The Macintosh 512 was only a Mac 128 with 512 KB RAM).
It had a lot of new features: the extended ROM held the new version of Mac OS, enhanced graphics libraries, drivers for hard-disk and external floppy-disk units, a SCSI bus, AppleTalk networking and the new file manager: HFS (Hierarchical File System).
The new floppy-disk unit could use double-sided 800 KB disks (only one-sided 400 KB for the 128). It had an enhanced keyboard with a numeric keypad and last, but not least, it had a SCSI 1 (1.5 MB/s) interface.
This computer would be succeeded in 1988 by the new Macintosh series: the Macintosh SE and the Macintosh II. However, it stayed in Apple's product line longer than any other Macintosh machine, almost five years, and was on sale until 1990.
I have a virtual museum of old Mac computers, each which run perfectly. I have a Quadra 700, that I still ue for graphic work, a PowerMac7300 with extra ran 128mb that I still use for Photoshop and designing agds and addition I have a Mac Clone, a G3 I believe. AQll 3 run perfect and still do the work they inteneded. Is there anyone inerested in buying these wonderful machines? I may keep the PowerMac7300. Actually it''s a PowerMac7200 with the guts of of a 7300. Let me now. Thanks!
By the way, all come with working monitors and have preloaded software like outlook express, Quarkexpress, photoshop, Adobe acrobat etc.

It is the Mac Plus which made an appearance in the comical Scotty/"Hello Computer!" scene of Star Trek IV. I've always loved that movie, and that Mac.

@ MARCY BRONFMAN (Croton on Hudson, NY/USA) If the Mac Plus computers are in good shape and still work I''m interested in buying them.
