That is what I was afraid of.  You have major damage to the IO and mother boards.   At get this working again, you will need to replace (or repair) those boards and possibly the card cage pan.   In reference to your original post, you do not have a Lisa 1 anymore, but a Lisa 2 that needs a lot...

It's clear from the photo that the system was converted (upgraded) to be a Lisa 2 (this was very common at the time).  Before you attempt to turn it on, open the back cover and see if the white battery pack in the lower right corner of the IO board (the large green PCB facing you with the cover...

It was upgraded??  Most Lisa 1's were upgraded to become Lisa 2's (MacXL's), this is what makes the ones that weren't upgraded rare and the ones that were upgraded not-so-rare. Does the system (or you) still have the 5 1/4" disk drives and faceplate?  Was the battery removed? Photos would be a...

Yes, it does appear to have a PDS pass-thru connector on the back edge, but it is only labeled P1 so with out documentation I cant be sure what it is. The board has 4 SIMM sockets on it each populated with 1 Meg SIMMS, the ROMs are pulled from the SE logic board and installed on the Turbo SE...

I have a Mac SE with a Mac Memory Turbo SE accelerator.  This board has a 16Mhz 68000, a 68881 math coprocessor, and 4 Meg RAM.  It works very well, but I do not have any drivers or documentation for it.  Does anyone out there have more information (or the software) for this board? Thanks, Rick

Yes, MacIP.net is back working now.  This is a very useful tool, Thank you! Rick

Just got my MacIPpi setup working this week and it's seems that MacIP.net is down.  I know that mactjaap (I think this is the owner) watches these boards, hopefully this is temporary, lot's of good information on his site. Rick 

While connecting an external monitor may be helpful in determining if the the system is outputting any video signal, be aware that the Lisa does not output a standard composite signal and requires a very specialized monitor.

If the COPS chips is bad/missing or the IO board is not installed the Lisa will "just turn on" when you plug it in. 

FYI, the GSOS does support appletlak laserwriters by downloading postscript code into the laserwriter that emulates an imagewiter printer.  

i don't think it's anything to do with caps... My guess is that your system had the "screen mod" installed at some point, this would explain why the screen is out of adjustment, and possibly why the vid rom serial number has changed due to the screen mod having been reversed.   Check if the...

ScutBoy, is absolutely correct!   MacWorks is not a emulator or simulator, but a Lisa Environment that loads into RAM the Mac toolbox code (patched to support the Lisa hardware:  larger display, HD, etc.)  allowing the Lisa to run the MacOS.   The screen kit is not required to run MacWorks and...

Looking at the SUN board: P1 is the data connector, this should be cabled to the PAR port on the back of the Lisa2 (or the internal widget par cable of the 2/10) P2 & P3 are the power connectors.  On a 2/10 P3 is used to connect the widget power cable.  P2 would be used to get power from...

The twiggy connectors are oriented, they have two notches on one side (near the ends) and the twiggy drive has matching keys that prevent you from plugging in upside down.  These cable contain power and data and would release the magic smoke if plugged incorrectly. On a Lisa2/MacXL one cable...

The switch on the PS is for the case interlock, it's wired with the interlock on the front of case under the CRT.  I doubt you will get the PS to startup outside of the system.  With the interlocks closed the PS will output a standby voltage that powers the COPS chip on the IO board.  When you...

Unless you are going to run MacWorks, know that the LOS requires a HD.  The installer for the LOS is a 5 disk set.  You could boot the installer from the floppy just to see if it works, but you will need to install it on a HD to really run/use it. LOS disk images are available here...

It's trivial to route the internal par port to the outside to attach a profile.  You only need a par port card if you want to run two or more hard disks. Rick

Not the same. (technically Macs use a single cell, the Lisa uses a multi cell "battery" that is is soldered to the IO board) See here: http://lisafaq.sunder.net/lisafaq-hw-io_batteries.html Rick

Identify what version of Lisa 2 you have:  A Lisa 2/5 with 3 DB25 ports on the back or a Lisa2/10 with only 2 DB25 ports on the back. Check the the label on the PS and verify that it's the correct 110 or 220 version correct for your area. If you have a Lisa 2/10 then just try to power her up...

I really don't know exactly when Apple made the transition to the Mac mouse on the Lisa.  I believe that all Lisa 1 systems used the Lisa mouse, many of these were converted into Lisa 2's.  Early factory made Lisa 2's also used the Lisa mouse for sure.  Later Lisa 2/10 models (AKA Mac XL's) use...
