Apple lisa repair.

There's usually a pair of 330uF 200V(?) caps in PC power supplies that might work for you. Just about every junk AT/ATX PSU I've come across has them. They might work in place of the 390uF caps.

just my luck the two I have taken apart have had the 470uf 200v ones in them, I was thinking of using these in series with a 100uf 200v to make an approximate of 370uf

small Update, after digging though my large collection of electronics I remembered seeing some 100uf 200v caps, So i will combine them with the 220uf 400v caps I have to make a replacement that is less then 20% off lets hope this fixes it.

Well good luck anyways.

yeah I found the problem a loose cap was causing the problem!

I think you should be able to buy foam for the keyboard at Michael's or a similar crafts store and cut it to fit the keyboard.

So what does the Lisa do on startup now? There is also someone selling a Profile in the Trading Post.

im actually going to buy the profile talked to him yesterday about it, so that is awesome, the install disks will format the profile for me right? I know you can not do the low level format without the apple III.

I actually have been using this weather striping foam for the keys it is sticky on one side and seems to work well on the ones I have fixed already although I think I may have broke the caps lock though, but I have it kinda working, i think the pin inside used to have a spring in it and it must have shot across the room so now it does not want to click and stay down.

it is turning on now and the first keys fixed were the apple and s keys so I can boot to service mode and can test the keys that way. I also found some new tdk ds/dd unformatted disks 50pk for a bit over $20 with shipping. then I can make all the disks I need.

I still want to make my idefile and have a new pcb ready to etch and the holes all lined up well so this one should work.

So does the Profile work?

he said he was not sure but it did spin up with ready light on. i would want it even if nonworking i can put my idefile in it, i did not hear back from him yet so i wrote him an email asking him how i should send him paypal, hope he writes me back soon

Hey patnukem, do you want a Lisa-ImageWriter cable? (One of these)

funkytoad is giving away an ImageWriter too.

thanks but i have way to many printers i should probably give some away.

What printers do you have?

um several personal laserwriters, imagewriter II, and some others

well this sucks the profile that was being sold in the forums says sold now and he never even wrote me? i guess i will have to live without it

I think he marked it sold for you; the stuff I PMed him about was marked sold today too without him contacting me.

well he did not mark the other thing i was buying so i was kinda doubting it and he read my last email about how I should pay and never responded. well I hope you are right and I can still get the profile, i was looking forward to having one, also I talked to vintagemicros about getting a replacement caps lock for the one I broke and he his going to get one for me he is such a nice guy and has been crucial to getting my lisa up and running.

im getting a caps lock key part, so my keyboard should be ready to go.

Update! I got a hold of matt and have paid him so hopefully the profile can make it here in one piece and I will have a nice looking lisa!

well I got my board etched it looks amazing, before I etched it there were some lines that I could not draw on or carve out so I colored the whole thing in Just 5 little traced and will cut them a part from each other (or if that does not work i will add trace wires and cut all of them, in addition one or two traced suffered and died when etching but they are easily fixed, Not bad for a homemade etched board. Here are some pictures you can tell the ones connected together I mentioned are on the bottom left of the front but that is the only ugly part I have to fix!

Front



Back

Wow; looks very nice! Even though if the ProFile you buy doesn't work, you could always jam the IDEFile in its casing.

thats what I figured and it would look more complete the lisa's with profiles on top always looked a bit more complete then ones without.

as far as the IDEfile I have to solder plate the whole board to prevent oxidizing and for the profile adapter socket It is the same one as an apple IIe keyboard socket so I am using one of these I plan to use as many reused parts as I can to cut costs since I am jobless atm.

CIB Lisa Mouse:

Just mentioning particular listings.

eh it ended I kinda would like a broken one with a good shell since I have an early 1984 mac mouse guts, that should work in the lisa one.

My blank disks came in and I got system 3.1 all the lisa apps and lisa workshop disks made. So we can only hope the profile will show up tomorrow and I can get this thing going. I did test the first system disk and it did not boot but after cleaning the drive out it booted right up, this drive still operates smoothly mechanically and it still has the felt pad unlike the 512k I had that needed a new felt pad and a oiling.

well it worked for a bit then the computer shut off. I was going to take out the PSU so I could get the computer back on, I bumped my homemade profile cable and it sparked and blew a cap in the profile. Anyway before that I did get the lisa os installed on the HD and started it. But I fixed both so we will see when I get a new cable and hope the HD did not die (when fixed the ready light still comes all the way on). here is a picture of it running LOS for the first time.



and the capacitor that popped.

So, any luck with replacing the cap?

yeah I have several spares (Thanks to my huge collection of apple IIe's and parts. The same cap is in at least one type of apple psu for IIe's.) Switched it out and it fired right back up to solid ready light. Since I think it broke because of my homemade cable getting bumped and then shorting, Now I have to order a cable I do not know If I want a cheap parallel serial cable (then take pin 7 out) or a real apple profile cable. Either way I will have to wait for it to arrive before I can fully test the profile again.

Any progress on the IDEFile and the ProFile cable?

I ordered a cable that should be here in the next couple of days, Ive put off making the IDEFile until I have more money to spend on it, but the board is ready to go.

small update: I got my cable today but can not trying it since my power is still out will post as soon as I can get power and try out the whole thing again.

well I finally got my power on today and everything on my lisa is working again (I had to repair the Profile install of LOS) but after a fresh install it started right up. I only have small adjustments such as a few keys and adjusting the video switches on the inside. The db25 cable I got seemed to work just fine after breaking pin 7 off.
