Not always... Early Lisa motherboards used a funky 9 pin connector with little tabs top and bottom and no nuts:   http://lisa2.com/Lisa-Mouse.jpg To use a mac mouse with these systems you can remove the outer shell of the connector on the motherboard (or cut off the tabs) and optionally add...

Yes, it' been done before: https://68kmla.org/forums/index.php?/topic/25212-is-it-a-lisa-is-it-a-macintosh/

No hacking there... The DB25 connector in slot 3 is a Sun SCSI card, you can also see the internal ribbon cable and a SCSI drive is mounted on the board.  49 Grand... tell him he's dreaming!

The original AUI standard provided 12V to power the transceivers.  Later on, most transceiver chipsets only required 5V.  I was aware that some AAUI ports only provide 5V instead of 12V and I will bet that the Asante card does not provide the 12V that the Apple transceiver requires. Rick  

For a mint ROM03 IIgs system with Transwarp GS, CFFA3000 Card, 8MB RAM card, keyboard, AppleColor RGB monitor, mouse, both floppies might be pushing $1000?  Yes, a grand would be a fair price. Rick

I should have stated in this post that my estimate is only based on what it's value is in the USA.  For all I know, €100 may be a good estimate in Europe.

€100 is way too low.  More like ~$650 USD + shipping for a good working unit is a fair price.  Demand is always going to be high for these things. Now is anyone here has an Apple 1 for €100, let me know... Rick

From the Imagewriter II manual:

The cable you need is the "Apple IIe Modem-8 Cable" Apple Part # A2C0311, use port B on the Lisa.   

The CPU card is the same (if that what you are calling the back card), and you can safely swap it in the two systems.  The mother board & card cage are different you can not swap them between the systems.  

That's an interesting question, the 400K system 6 install I was referring too was specifically for use with MW+.  MW+ is doing Mac Plus ROM emulation (128K ROM) with the Lisa's 1 Meg of RAM and HD, so it would be much more like running system 6 on a Mac Plus with a 400K drive (something that...

From the photos I saw, the system has the H roms and an X/Profile.  It will run the LOS or MW just fine. For the record: No version of MW requires the Screen Mod, and there is no such thing as a "Lisa modified to run MW".  Macintosh XL was just a marketing term apple used. 

Do not put the 2/10 IO board in the 2/5, unless you want to release some magic smoke.  

MW+ does not require a 800K drive.  The MW+ boot and install disks are 400K, and SunRem had special set of 400K disks to install system 6 on the hard disk.  What you can't do is boot System 6 off a 400K floppy, it does not fit.

Flexo, since you can even get into service mode right now: If your Lisa has two RAM boards (most do), then try powering on the system with just one RAM board at a time (in the slot closest to the CPU card), and see if the 71 error goes away.  This is an easy to see if you do in fact have a bad...

A brand new replacement for the COPS chips is now available: http://www.ebay.com/itm/NEW-Lisa-X-COPS-Replacement-for-Apple-Lisa-COP421-Chip-I-O-Coprocessor-/142137574733?hash=item21180f454d:g:XKQAAOSw8w1X8qER I have one and it works perfectly. Rick

No, this is incorrect.  Flexo has verified he has the proper "H" ROMs to run the LisaOS.  The LisaOS has no issues with Sun 800K IO FDC ROM.  He will still need a par port hard disk to run the LisaOS. Yes, I have this software and I can confirm it works well allowing you to store up to 800K on a...

I do think the board is very reparable, but it will take some electronic skills, the only alcohol needed may be a beer for the brave soul who takes on the job!  Keep watching this board and ebay, a solution for these rotting boards may be available sooner than you think. The SUN ROM is very...

In your photos, I see corrosion on the board.  Look in the battery area at the traces running to R45, R46, C46.  Note how these traces are almost black in color, compared to the normal light green color.  The battery that was there surely did leak and the corrosion has migrated down those traces...

No, that's not normal.  If the I/O ROM rev is not showing, this means that the 6504 CPU or static RAM in the FDC part of I/O board is not working.  The seller's story about the missing battery causing the error 71 is incorrect.  Try removing the COPS chip and look closely at/under the socket...
