And this is why I love this group. Great info here!

Mmmm I was going to do a precautionary recap soon on the machine anyway even though the machine worked perfectly and seemed in good shape. I will pull the RAM for a start and see i…

Might reseat the roms and memory. Caps of course if you have not already.

So, It would appear the first line indicates initial memory test fail, however I am not so sure how to decode the second line exactly... Also, I not on a 4th bootup attempt, where…

The Apple part number may be different on the label, I don't know if it is or what is should be to indicate a 2/10. The normal differences that I look for to indicate a Lisa 2/10 …

Since the 128 and 512 were same board when the 512 was introduced I would think so.

Should be , I have a donor 512 but have not found them since moving.

Thank you for this update. So this was a formally Lisa! Nice to know! Could you tell me two things: -Is it normal to find a sticker on such a Lisa that indicates that it is a Mac…

1st of all you don't have a Macintosh XL (AKA a Lisa2/10), you have an original Lisa ( Lisa 1 or converted Lisa 2).  The two 26 pin ribbon cables are for the upper and lower twiggy…

McD replaced my ram and it changed nothing then changed it back since it was the apple branded ram for me, which as a 128 is kinda cool for me.  I have 2 working 128's but both upg…

Too bad. I have a Simasima 1400, and it turns out that the 1400 is OK, its the LCD Screen that is Simasima. I would love to fix that one day. 

Too bad you "HAD" that 5300, Bibilit. Not only is there problems with the power connection on the 190/5300 but sometimes when the battery leaks, the PSU Area (under the trackpad) i…

I looked at your pics (it did not load the first time I posted but that is on my end). Sad news. Looking at the bottom board, I saw several of the solder joints from the capacitor…

i found some trace on the back side of board. that looks like someone had tryed to resoldering or replace ram. but every ram has thext "4264" with apple mark. so i thought someo…

You're missing the Widget's power harness. That three pin power cable is for a Twiggy floppy drive and indicates that your Lisa did not start out originally as a Lisa 2/10 or an XL…

Even if the motherboard is busted in the XPS there is still really nice components inside. I'm surprised the owner didn't salvage the really nice parts on the inside.
