Hi Jason,
your search to find the error is going on.
I have tried powering the Lisa with the drive cage removed, same result.
I have not tried powering it on with the ram cards removed. I'll try that
now.
Check that first, before we take a closer look to the PSU

Hi David,
Q: Can the Lisa 2's external RCA video connector be used to record video
output on a NTSC video camera?
Not directly, but you can convert the signal two times and then e.g. feed a
modern computer with the digital signal.
I did this with an Apple IIe and later with an Apple IIc (which
Hi !
I only have a pair of Lisa OS 1.0 disks, which were used in Germany at a
nearby Hard- and Software Develloping Factory, which had a short cooperation
with Apple in the mid 80ies.
They intended to develop an Audio-I/O Card for Lisa and Apple gave a set of
7 Lisas so that the engineers there
Hi,
a short remark concerning Lisa OS.
There have been some developer systems, too.
These were not available for custom users, but apple supported selected
developers with a (or even several) Lisas and software. Here's the
picture of such a software disk:
Hi James !
I hope these prove useful to those working to keep Lisas running!
Well I think this sentence has to be a little modified. The correction
must be:
These re-engineered schematics ARE very useful to those working to
keep Lisas running!

Hi Marcin,
try to answer the questions:

Not the Lisa has an internal fan, but the hard-drive compartment had

The fan was placed below the widget drive or/and behind the floppy
drive.
Secondly, does the ProFile hard drive have a fan?

open the keyboard and check the board, whether you can see any corroded

If yes, try to check the multiplex connection from the

What are normal Widget sounds?

Yes, that's normal. I also have that sound on my drives.

I have a sick 2/10. When I push the power button, there is a 'whump' ...
definitely your Switching Power Supply is weak, or your Lisa has somewhere a

The Whump comes from the PSU trying to power-up, but immediately shuts

Hi everybody,
concerning the dangerous behaviour with a Lisa (or similar) switching

It's true: The +300 volts is generated on the video board
