Re: Lisa won't stay off (was Lisa 2: Bad Disk Drive)
Le 12 nov. 05, à 00:33, James MacPhail a écrit : This was an aside to another problem, so it looks like it didn't get any attention: when I switch the Lisa off, it goes off then on immediately. I have seen a couple of causes for this problem, ones that come to mind are: 1) Damaged (broken) traces on the I/O Board due to corrosion from leaking batteries. After removing battery, and cleaning as much as I can the board, it's OK ! I also clean all socket. Great ! More over, I test second second board (Cage, CPU, IO, 2 RAM Card and one // card) and it's working also :happy:. This second board as a different ROM version (H/A8) athough the first one is D/A8. Is there any real differences ? Which one is better ? When started with the H/A8 board, the Lisa will only ask to boot on drive 2, although it let choose Drive 1 (which does'nt exist ?) and Drive 2. Both Profile start on MacOs. *but* despite all my effort, the diske drive remain not functionnal. It make some noise at startup, like if head are blocked... I will try again to dismantle it and grease everywhere again... May be somebody have a spare diske drive ? Or Macintosh drive may work ? Lisa is my best piece of old computers, far away from my other Apple pieces likes Apple II, macintosh 128 What a beautiful thing ! Jerome -- LisaList is sponsored by http://lowendmac.com/ and...

Re: Lisa 2: Bad Disk Drive

May be somebody have a spare diske drive ? Or Macintosh drive may work ? The 400K drive is the same as in the 128K and 512K Macintosh, so if you have one of those (and it sounds like you do), you could connect it to see if it works. If not, then suspect the I/O board and connectors. If another drive does work, then the original drive would seem to need maintenance. Other than the sticky grease problem, check to see if the pressure pad is still on the drive. It is a small felt pad opposite the read/write head, when a disk is inserted, it is the thing that holds the magnetic disk against the head. Sometimes the pressure pad falls off (or is torn off by forcibly ejecting a disk when the grease is sticky). Congratulations on fixing your off/on problem!

Do you think that a 800k drive from a Mac Plus -less value than the 128 or 512 ;)- will work, at least as a 400 k drive ? Other than the sticky grease problem, check to see if the pressure pad is still on the drive. It is a small felt pad opposite the read/write head, when a disk is inserted, it is the thing that holds the magnetic disk against the head. I saw the presure Pad, seems to be OK. In fact, the drive don't spin, or try to spin then go off, and Lisa eject the disk with Error 23 or IO board error 39 (timeout). This is done with both IO card.
