Apple Lisa

What? You were expecting something else? Hmmmmm........

The Apple Lisa was the first GUI system to get anywhere near the 'mass market'. OK OK, it set the world of computing on fire, not the sales figures... I recently acquired a couple of Lisae, and took some pictures of the strip & reassembly of one which needed some TLC... a lot more Lisa stuff to come, this is really just a placeholder.

Start with the barest chassis....

 

Add the sheet metal parts and wiring harness...

 

From the rear...

 

The CRT, flyback transformer, and CRT drive board go in. Side plastics in place...

 

The PSU goes in...

 

The drive assembly: 10Mb 'widget' hard disk on top, 400Kb floppy below...

 

Installed in the chassis...

 

The boards are on a backplane which slides in - here the two 512k memory boards in front, and the processor board with purple 68000 prominent behind...

 

From the other side, showing the I/O board. Note the three Lisa-specific expansion slots on the left...

 

The boards & backplane slide into the chassis...

 

The remaining plastics go on....

 

And the back cover... front & back covers both actuate microswitches which prevent the Lisa frm powering-up with the covers removed. This seems a common cause for many reported 'power supply' failures!

 

By some miracle, it works! Unfortunately it doesn't have the Lisa OS installed, it's running MacOS... still trying to get the downloaded Lisa OS images onto readable floppies.
