For your consideration is a very rare Apple Lisa 2/10 prototype. This is a special machine and it has been serviced to be operable.Features a Non-Apple/Non-Original front bezel featuring a replacement Lisa logo badge.

This prototype differs from production units in several ways:

• The handwritten ROMs originally installed on the machine produce a ROM configuration never before seen “D/92” these were examined and compared to all production ones and none of them are the same (slight variations) - please note: Prototype ROM image not posted online anywhere - this is the buyers choice to do so

• The model number is that of a Lisa 1 not a Lisa 2 or 2/10

• The solder mask is a different color, and there are some minor differences of parts and their locations part numbers yield no results online besides another prototype (production numbers different)

• The date codes on most chips are from before the launch of the Lisa 2/10 (most1982 or 1983) and the Widget drive was reformatted before the launch

• Apple Asset tag is visible on the case

• The mouse port on the rear is the kind used on the Lisa 1 and 2/5 not the 2/10 which used the Mac style connector

• Rear sticker indicating ports was never installed

The following service was performed in preparation for the sale:

• New foam pads on the keyboard

• Replacement of any capacitors out of spec

• Cleaned and lubricated (but untested) Apple 400k floppy disk drive

Items included in the sale:

• Keyboard w/ new foam pads

• Apple Lisa 1 – 2/5 Type Mouse

• Original Prototype I/O board that was removed as it was defective (currently has a replacement installed)

• Original Prototype ROMs removed that behaved strangely and produced “D/92” ROM declaration

• Original Prototype Widget drive with "XXXX" in the part number indicating the final part number designation was not yet chosen - this drive tried but failed to boot and was replaced with an X/ProFile.

Special notes: 1) The video has some vertical jittering likely due to a bad replacement job on the vertical-hold potentiometer on the video board 2) Some mild case non-uniform yellowing is present w/ general "patina" visible 3)This is a prototype owned by Apple from a Lisa 1 used to create the Lisa 2/10.
