My sick 2/10

Hey guys, got a question for ya. I have a sick 2/10. When I push the power button, there is a 'whump' from the speaker, the diskette drive motor spins a little, and that's is. No lights, CRT activity, nothing. I have cleaned the contacts in the power button, didn't change anything. I replaced the

Re: My sick 2/10

David, thanks VERY much for that schematic. I had been searching and searching but could only find the one for the 1.2a unit. I have tried powering the Lisa with the drive cage removed, same result. I also tried unplugging the CRT board, same result, except that the whump was louder. I also cleane

Re: My sick 2/10

From left to right 8 connectors with 7 cables are: (+5V) (+12V) () (Ground) (+12V) () (empty) (-12V) Ok, I'm testing her now, that this is what I've gotten. The +5v wire has .02v on it when the lisa is 'off'. It jumps up to.7 when I press the button. It might be more... my meter takes a few moment

Re: My sick 2/10

Is it possible that the power supply is "ticking" after you try to turn it on? *snip* There is an adjustment for the power supply, through a small hole near the middle of the big side. You normally have to take the PSU out of the Lisa to adjust it. (and repeat until the voltage is right) Turning t

Re: My sick 2/10

Oh NO I hope you marked the original setting. Setting a pot will not repair the PSU. Don't worry :) I marked it carefully, and reset it after I was done. I didn't touch the other pot. That's why I asked, instead of just messing with it and blowing up the system. I've blown up enough electron

Re: My sick 2/10

Ok, I'm doing this from memory now... The 5v standby was giving 5.xx volts The +5v section was giving 7.xx volts. The +12v section gave 13.xx when power was first applied, then faded to .08v I guess I like giving contridicting information :o -Jason - Original Message - From: "macmoni >Sche

Re: My sick 2/10

> Ooops ?! That's a different voltage compared with your last mail. I did some more checking after letting the PSU still all night. the +5 standby reads 5.4v The +5 reads 5.6v the FIRST time it's turned on. But, If I cycle the AC, it goes up. By replugging the PSU a few times it went all the way

Re: My sick 2/10

I think I've found the problem! My friend suggested that I check the diode CR8. Shure enough, it is bad! Almost infinate resistance. New parts will be ordered shortly :) Thanks all, very much! -Jason -- LisaList is sponsored by and... Shop buy.com and save.

Re: My sick 2/10

She lives!!! Kindof... That CR20 diode was broke... replaceing it made things go a litle better... we blew U1 on the video board. Replaced that.. and the machine fired up! Hard disk throws an 81 error.. but I'll deal with that latter. The main problem is that the voltages still aren't quite righ

Re: Lisa books

Forgot to mention that +5 and +12 voltages looked good. Readings were taken from the card edge connecter, and from the hard disk power leads. Repairs were possible thanks to John's schematics. -J -- LisaList is sponsored by and... Shop buy.com and save.

Format a Widget with an apple III

Another question for the experts. I read that the ProFile could be low leveled with an Apple III and some software. Could you do the same with the Widget disk or is it's command set different? Reason being I've got a Widget that's had it's magentic half life.. and Sun Rem. doesn't serivce them a

Well.. I'm happy to report I'll never have to find out!!! My Widget started working after I moved the stepper moter around a bit with my fingers :o She is now runnin 7/7, just like she should be. As for a ProFile emulator, see here: http://john.ccac.rwth-aachen.de:8000/patrick/idefile.htm I was

Maby try some contact cleaner on the pots at the top of the video board. HAVE THE SYSTEM OFF AND UNPLUGGED. High voltages!!! First use a sharpie to mark where they are set. Spray the pots with the cleaner then adjust them back and forth. Because you marked where they were set, you can put them

Re: Vertical Hold problem

Good advice. I would also recommend you leave Lisa on for 30 minutes or so before you adjust anything. Sometimes the image on the CRT can shift as it warms up, so adjusting it when it's warm will make your adjustments stay. And you see that red wire that goes from under the crt to a suction cup

Re: Lisa + Profile and SCSI cable?

Is there any way to get at the bearings of the drive? My profile is easily the loudest drive I've ever heard, save the 2 gb Barracuda I threw on the floor repeatedly and then powered up (it dances across the floor now! Don't worry, it had many bad sectors before I 'stressed' it.) I took the brus

Re: Question about 1 vs 2

I'd give the cable a try. If it doesn't work, it won't hurt anything. If that's the case, pick up a modem emmiminator or null modem adapter, and plug it between the cable you have and the Lisa. -Jason From: [EMAIL PROTECTED] (Adam Vaughn) Reply-To: "LisaList" To: "LisaList" Subject: Re: Qu

Re: Lisa keeps shutting itself off

Adam, Does your comptuer have the 1.2 amp power supply or the 1.8? Perhaps its overheating? Maby aim some fans at the vents on the back, or take the top off and have a fan blow in there (warning: High Voltage!) -Jason - Original Message - From: "Adam Vaughn" <[EMAIL PROTECTED]> To:

Re: Lisa keeps shutting itself off

My Lisa indeed has a 1.2A power supply (no idea why Sun Remarketing decided to keep it hobbled with the original PSU after they installed a hard drive in it...). __The 1.2 amp PSUs do have a temp sensor in them which will shut the system down if it overheats. As stated in an earlier post, th

I do not have the plan for the 1.8 amp PSU. I did have the plans for the 1.2 amp, if I can't find it on my computer, I'll download it again. The plans for the 1.8A are not available on the internet as a PDF. VintageMicros was selling ones they had made on ebay a while ago. I picked up a set

After the drive spins up, you hear the clack of the brake, and then the head starts seeking around, right? It should be seeking around a lot, not just a blip ever second. When I got my Lisa, its Widges was non functional. When I powered it up the drive would spin up, but it would just sit ther

Hi lucky Jason ! a little damaged seleonid brake or greas, which has become hard during that very long time or dust will cause this error... The thing is I had allready un-stuck the head motor when I un-stuck the brake. The heads could move around just fine. Eh, what'll ya do :) -J -- Li

Phil Before I replaced the dual diode in my PSU, the power button would produce a pop from the speaker, and that was it. The dual diode is down in the bottom left corner in this pic: http://compu85.homeip.net/stuff/Lisa/Power%20Supply/S3600129.JPG The one I replaced it with isn't in the same

Cool! Glad you got her working! Previous owner leave any interesting documents? I got a profile a while back that was full of engineering drawings! The widget is the most unique sounding drive I've ever heard. Mine runs very quietly actually, save the squeaka de squeak of the head voice coil.

Lisa schematics

Hey guys, I'm renewing the caps on my Lisa's video board, and was looking for the schrmatic. All the sites hosting them seem to have gone down... or I just can't find them anymore. I know that a PDF of this exists because I printed it when I was working on the power supply about a year ago.
