  1. I have worked on dozens of these boards, and the capacitors have never been the problem for me... Try replacing the voltage 7824CT regulator U1 ( at lower right corner of the board ), an indication that this is failing is that the the resistor R1 will be burned/cooked (and should be replaced also). This is a very common fault on these boards as they age. Good luck!
  2. I am in Chicago, maybe some day we could create a Trans-Atlantic Appletalk network, I can setup my Lisa as a file server..
  3. Another neat thing the gatorbox can do is tunnel an appletalk network between to gatorboxes using tcp/ip. Note: The configuration does work best with classic macs, You must configure it using local talk, and the configurator does not support open transport. also be aware that the early models have no rom or flash and must booted via a sftp server.
  4. As was said, it does not matter if the cabling is LocalTalk or EtherTalk. But note that MacIP is only supported up to System 8.6, System 9 users can not connect using MacIP. Your SE will not support System 9 anyway, so for this case it is moot.
  5. I have done this before. This will work fine, just make sure you don't plug in the "lisa lite" board ( and you won't have a floppy). Rick
  6. Dog Cow, Great! I would be happy to test your project on the Lisa when you are ready. Thanks, Rick PS. I have a copy of the source code for MacPPP 2.01 if it would help you, PM me.
  7. Great! Please keep working on this. I would like to connect Lisa's running MW+ ( 1MB RAM and system 6.03 ) to a serial PPP server. My problem is MacPPP works best with System 6.07 and better (that the stock Lisa can't run) and eats up a lot RAM ( Lisa has 1 MB RAM, but MW+ uses over 256K, leaving less that 700K usable). Also, the stock 5Mhz Lisa runs a little slower than a Mac, causing issues with some PPP clients internal timing. I need a very small, fast serial PPP client that will work with System 6 or System 5. Something like Marina for 68K... Thank
  8. Absolutely! The Macintosh II ( 1987 ) supported as many displays at you had slots to put display cards in ( in this case qty. 6 ).
  9. Just as some background info on the 1.2A Lisa PS, this is a quote from the Sun Remarketing Lisa DYI guide circa 1990: "When the original 1.2-A Lisa 2/5 supply is used with an internal hard drive and a Macintosh XL Screen Kit (described at the end of this chapter), audible transformer ringing results, horizontal retrace lines become noticeable, and a slight screen flicker is introduced. Installing the 1.8-A Lisa 2/10 to Mac XL supply eliminates all of that." I experienced this first hand over 30 years ago. My point is that even when working to original specs, the
  10. "F-ROM", that makes sense now. If you PM me, I will send you my H ROM images to compare with what you have. Thanks, Rick
  11. I am confused, are you saying that have another working system with "H" ROMs that the VidRom does work in?
  12. Sounds like an issue with the VSROM to me. If you are switching from the ScreenMod(3A) ROMs to H Roms, then using the correct VSROM (non-ScreenMod) is mandatory. Where did you get the VSROM, how do you know that the VSROM you are using is good? Rick
  13. PhoneNet was designed to use existing building wiring ( Cat3 ). I have run LocalTalk over Cat5e cables for decades, I even use standard Cat5e Ethernet (RJ45) jacks. Regular phone patch cords (RJ11) will plug-in and work fine with the RJ45 in the wall to connect the Phonenet adapters. Only thing is that you need two jacks at each location for daisy-chaining. I currently use a GatorBox with a LocalTalk repeater and make home runs for each node like twisted pair Ethernet. Rick
  14. There is an extra grove on the connector to indicate pin 1. Rick
