my first Lisa

Recommended Posts

Said I may as well start a new thread for this 

 

She arrived.

 

I took pictures and filmed  as I took a look

 

Looks clean. The labels have fallen off some of the rom chips - i covered them straight away with tape to keep the light out

 

But 1 bad supprise. The hard drive has been purposely destroyed

 

It looks like someone took it out and smashed it off a wall for a few hours. 

Platter and armature gone, chips TORN off, bits of the boards torn off. ...Looks like someone vented some extream anger on this poor drive

 

Happily - the rest looks great.

 

No battery, no leak. Despite the main boards being covered in dust , they look very very clean under the grime

 

220 volt psu

 

will start to clean it all up over the weekend and try powering it up in a day or 2

 

whats the story with replacement hard drives for a lisa... had a look on ebay and no sign of anything close to this drive

 

I dont even know what OS a lisa runs on - is it totally different from the 128K system 1

 

oh god........wheres me glasses

Oh my. That is a beautiful Lisa...

 

As for the hard drive, I believe there is a thing called the X/Profile that lets you use a CF card with your Lisa. They are rare, though.

Congratulations on your new 2/10 falen!

I hope she'll boot right up. It's a shame that HD is beyond repair. Carboy is right though, the X/profile is the way to go (unless you have a Parallel card of some sorts... You could hook it up to a Profile... but these things are damn expensive and most of them are toast)

IF you are serious about your soldering skills, you could build an IDEfile yourself... all the ressources are there.

 

Good luck.

Thanks people

Eagle - idefile looks like a good option - just had a quick look - will focus on the rest of the machine first but at least there are paths to take 

 

It is very clean (besides the 30 years of dust) - cant see any decay of any kind on the main boards

 

allot of yellowing on the outside....... but i love it

 

This is a 220 volt... i wonder how many of these were made. To be honest I was amazed to find this one in Ireland at all!

 

question - i have 40mb external SCSI for my compact macs - just checked the connections - would it work on the Lias or will it blow something up

 

 

Made a video of the tear down but when I saw the damage to the hard drive .... the cursing began!!!......... will have to do allot of 'beep's' in the edit!!

 

still cant get over the keyboard connector - 3/4 inch stereo jack.....wow!

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.

I'll have a look at your video later tonight. I like the Lisa, I wish I had one!

To answer your interrogations...

 

This is a 220 volt... i wonder how many of these were made. To be honest I was amazed to find this one in Ireland at all!

110V units were built in the US and 220V units were built in Ireland (couple of km from where you live I think). Every single Lisa 2 (don't know about Lisa 1...) sold in Europe was made in Ireland, but Apple didn't sell much of Lisas in Europe so it's kinda rare all right.

 

 

question - i have 40mb external SCSI for my compact macs - just checked the connections - would it work on the Lias or will it blow something up

It just WON'T WORK. Don't know if it will blow something up but a Lisa uses Parallel, not SCSI.

SCSI cards were available back in the Mac XL days but don't know for sure if they were compatible with the Lisa OS. Probably not!

 

 

still cant get over the keyboard connector - 3/4 inch stereo jack.....wow!

Yeah, unfortunately the Mac keyboard is 100% NOT compatible. 

And your keyboard troubles don't stop there: this is a capacitive keyboard, and the capacitive foam has disintegrated over the years, you'll have to re-foam each key individually. But first of all you need to get it going! Don't worry about the keys for now.

 

 

BTW, nice anti-glare filter you got there on the CRT.  :)

WoW - Lisa's were made in Ireland.. i didnt know that. The brother said they were not - but then again he is a thick as i am!!

 

What is the OS for Lisa - is it available on mac garden - can I make a boot floppy?... i imaging the OS will fit on a 400k disc..

 

Pretty sure ill get the floppy driv working so if the machine fires up ill be able to get to a desktop

 

I have made lots of compact 68k mac floppys using transmac but Im thinking it wont be that simple - these are 400K  drives aparently

Opened up the PSU

 

Lots of foil caps and the 2 biggest caps look rounded at the top

 

What ye rekon - power it up  or just recap the lot !!

 

Pretty sure some of thoes foil caps will go bang and make a big mess

 

Cleaned off the dust and it looks good - no sign of burning, leaks or any other damage.

 

Few dry solder connections - will solder them up

Just plugged in the PSU on its own - nothing happened

 

will have to make a list of parts to order up - anyone got a list of replacement caps

 

Does this psu run with a soft start capability.....

 

will plug it in again and have a look with the meter

 

but no smoke or bangs yet!

And i was looking at that switch. Ill try it  again. Plug it in, hit the switch and that should send power through it.  God I hate this..... has to be done

 

 

Hi armor

The hacked Apple II is all put back together and on the floor behind me. I got it as far good powersupply running apple iie board, connected to the screens analog board and giving a good signal, floppy drive working.

 

The old hard drive still had a 5 volt to ground short . I have a possible way to fix it now but I just havnt got back to it yet. Ive gone into vintage synthesizers now, was not expecting to be messing with old apple machines for a while....... but then the Lisa went on sale in Ireland.

I was bidding on a faulty  Prophet VS a while ago - missed it. Man some of those old analog synths are just awsom on the inside - spending hours on youtube watching some guy calibrating an osilator on a moog.................my condition is spreading

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.

Sure my apple Tam is still waiting up in the attic to be finished.......

whole day to get it taken apart

 

thought i found some rust on the back of the analog board - was only dust.

Its all there and all looking clean

 

still finding bits of the hard drive in the case. Someone took out the hard drive, disassembled it, then tore chunks out of it......................and then put it all back in the machine.

Those widget drives are even more rare than the Lisa's, there just is/never will be anything directly compatible (besides an aftermarket 'Sun Remarketing' 20mb drive, but I believe it only works under Macworks. You can also go the Xprofile route that someone mentioned, but its close to $400.  I'm lucky that my Lisa's have two working HD's, although who knows for how long.  Yours looks really nice and clean after some scrubbing!

Hi everyone.

 

Tried to power it up

 

card cage and Io card installed - nothing else. Back plate on, front plate switch on 

 

hit the power switch - light came on - nothing else. No display, hum from display of any kind of noise.

Hit power button again and it would not turn off (watched a video of a guy doing a smoke test on lisa - i copied what he did, just IO card.. BUT... his machine did turn off when he hit the power switch a second time.

 

pulled the plug. Tried again. Same, light on, wouldnt turn off on second hit

 

Tried a third time. Tripped the house fuse. No smoke, no bang, no noise of any kind. 

 

Took it apart and no damage of any kind, that I can see.

 

took PSU apart - looks the exact same as it did yesterday - nothing went bang, no smoke, no burning smell..... zip

 

Have PSU circuit board out on table. Will recap it. 

 

Discharging.........  will 240 volt bulb across the main big caps be OK ?........ im frightened to go near it - took it out by holding the edges!

 

been looking for a capacitor kit ..... no joy.

I count 7 rectangular foil caps and 8 radial caps (including the 2 big ones)

 

Replace them all?

 

if anyone knows anyone doing a kit for this.. please let me know

 

oh the joys of it!!

Replace them all.

 

I think no display means dirty contacts.

http://lisafaq.sunder.net

 

"A used Lisa may not turn on because it is missing some component. In order to turn on, a Lisa requires:

 

power supply

card cage with motherboard

I/O board

In order to show something on the screen, a Lisa also requires:

 

CPU board

one or two memory boards

CRT, video card, and flyback transformer (the latter two are hidden in the chassis behind the CRT)"

 

For the crt discharge don't bother with a lightbulb. Just get some alliance gator clips and clip one to a long screwdriver with a thick handle. Wedge it under the cap and touch both metal prongs. You will hear a snap or squeak if there's anything. Do it a few times and you good to go.

Those poor uncovered EPROMS. :(

Under normal conditions I've seen uncovered EPROMs last years without problems (with thanks to being inside cases where light penetration is minimal).

 

HOWEVER there are countless warnings not to use flash photography in the proximity of an exposed EPROM. It doesn't kill the chip but the UV discharge is known to randomly flip bits and require a full wipe and burn to restore whatever was on the chip.
