    Lisa1

    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 work, but is still worth saving. Rick

    Lisa1

    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 off) is present and take some close up photos of the area. I fear that if it's been sitting in the box since 1987 you will have battery damage. Also, in your photo you have a Macintosh mouse and a Macintosh Plus keyboard in addition to the lisa keyboard and mouse. Rick

    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 help. Rick

    Turbo SE accelerator

    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 board. There also is a small amount of RAM on the SE logic board, only 2 SIMMs, I am guessing they are 256K but I did not verify this. There appears to be no hacks on the main board, everything is cleanly interfaced thru the PDS slot. The finder reports the system as having 4Meg RAM, Speedometer reports the system as running about twice the speed of a stock SE, but Speedometer does not see the FPU. Sound seems to work OK. Rick

    Turbo SE accelerator

    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
  6. Yes, MacIP.net is back working now. This is a very useful tool, Thank you! Rick
  7. 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
  8. 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.
  9. 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.
  10. FYI, the GSOS does support appletlak laserwriters by downloading postscript code into the laserwriter that emulates an imagewiter printer.
  11. 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 screen mod transformer is (still) installed, if is then you will never get it adjusted correctly with the 'H' ROMs installed. Rick

    my first Lisa

    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 in no way does the screen kit make a Lisa into a Macintosh. Falen5 has a Lisa 2/10, and it does not matter it has a screen kit or not, it's still a 2/10 and if he uses the "H" ROMs and vid prom and get a working HD he can run the LisaOS. AFAIK, apple never sold "MacXL's" with the screen kit pre installed. Rick

    three cables in a Macintosh XL

    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 upper (longer) twiggy cable on a Lisa2, the other twiggy cable would go to the Lisa Lite card. To locate pin 1 of P2 see this photo: http://www.mirrorservice.org/sites/www.bitsavers.org/pdf/apple/lisa/sun_remarketing/Sun_MFM_Controller/Sun_MFM_Top.jpg Hope this helps. Rick

    three cables in a Macintosh XL

    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 would go to the LisaLite card for the sony floppy and the other is not connected. The Sun HD gets its data from the par port on the back of machine. HTH, Rick

    my first Lisa

    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 press the power button, the COPS chip sends a signal to the PS output the running voltages and start the system. Don't make this more complicated that it is, the caps in the PS are rarely an issue. Plug it in and go for it. Rick
