  1. Yes, MacIP.net is back working now. This is a very useful tool, Thank you! Rick
  2. 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
  3. 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.
  4. 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.
  5. FYI, the GSOS does support appletlak laserwriters by downloading postscript code into the laserwriter that emulates an imagewiter printer.
  6. 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
  7. 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
  8. 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
  9. 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

    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

    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: http://www.macmothership.com/lisacontent/lisahome.html Rick

    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
  13. Lisa mouse

    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
  14. Lisa mouse

    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, you can do no wrong. If you have a Lisa 2/5 then first open the back cover and verify the batteries have been removed from the I/0 board. If they are there remove them immediately and most likely you will have a major corrosion issue to fix. If the batteries are not there then look for corrosion on the board in the lower right corner. If it's clean ( doubtful ), then try to power her up. Your floppy drive will most likely need to be serviced (cleaned and lubed), and your keyboard will need to be rebuilt with new pads. If you have 2/10, the HD may sound like a 747 taking off (this is normal), but don't be surprised if it does not work, if it does, catastrophic failure is imminent. Good luck. Rick
  15. Lisa mouse

    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 the mac mouse. Of my 3 Lisa systems, one 2/5 has a Lisa mouse, one 2/5 has a mac mouse, and my 2/10 has standard DB9 connector a Mac mouse. My 2/5 with the Mac mouse still has the special connector for the lisa mouse the the outer shell removed and hold-down nuts. I believe is came from Apple that way. Electrically, the Lisa and the mac mouse are the same, and in the early mac days is was common for mac users to use the Lisa mouse on the mac. Rick
