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…

it could also be the 74ls244's all the ram is connected to, When i assembled and installed a MacGusto II upgrade board onto one of my 512k boards i got something similar and the in…

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…

video artifacts and sadmac code is all bad ram.   who swapped your ram chips for no charge grandpa?

Just FYI my ram was swapped with new chips and no change. If you have video artifacts with the error code another chip may be at fault. I have yet to figure it out. Now that I a…

IT needs a re-ram. i offer this service... its a big nasty job.    i did 2 over the weekend.

hello. today i got a 128k logic board. but it came with sad mac code "04006c". when i turn it on i heard bong and that code came up. i had serched the code through internet "goo…

PB 1400c use Sharp LQ1142 11.3" screen. You can find some alone on the bay, but not cheap. Don't know in what other machine it's been used...

Not possible sorry - the connectors, timings, etc are all different across most LCDs.  Do you have a part no for the LCD, it might glean more info if it was also used say in a Tosh…

if you can clean up the metal then solder will stick... so you can take some flux and some wick,  and with your iron,  rub what ever surfaces that are eaten up,  and maybe those su…

w/e - where am i going to find a better most likely irreparable practice board for pad repair... seriously though I tried a lot of stuff... is there any tip you can think of of how…

i wouldn't say its anything about skill level with this board... i would just say that working on it might not be healthy for one's sanity... that board is F'ed up man.

Charge light doesn't seem to work but it does seem to be charging.
