There are 3 main revisions of the Lisa Hardware, the original with the twiggy drives (Lisa 1), the updated version with one Sony drive (Lisa 2) that is otherwise the same as a Lisa…

I wouldn't attempt any upgrades to it besides possibly a SCSI card and maxing the ram out. It would however be nice if you could dump the BIOS and store it somewhere for safekeepi…

I need to find photos, if I have any, of my sold Mac XL. I am starting to think it had that spare cable too now. But its been so long.

The sticker on the case says A6S0300P  Thats why I call it a Macintosh XL. See: http://en.wikipedia.org/wiki/Compact_Macintosh I find it complicated these names.....

The 220V-240V, 50Hz, .7A PS would be correct for Lisa's in Europe, it's nothing special.  Later Lisa 2/10 (XL) units with the widget drive used a 1.8A PS that was internally 120V-6…

I second what uni said, be assured after decades these caps are going bad, even the best caps will dry out and not do the job.

Hi,  Many news : i can't boot on a USB drive (no option on the BIOS) and can't use a real graphic card : i have tested with many GPU and i have no screen. Just photos.

I did replace the 74ls244 and then errorcode was chaged "020002". so i also replaced the F6 Ram. now it show the errcode "04FFFE".  

Yes those ICs are compatible from the 512 K , The ram is also compatible if you change it all and of course you will only see 128k of it.

Well if you test continuity with a meter and it's not there and should be just run a wire. I can't tell from the picture.
