I'll have to go dig my ProFiles out of storage again... I'm pretty sure one or both of mine are a "middle" revision that still has the early board but lacks the bodge and didn't populate the test point pin header.

Quote from: patrick on March 06, 2026, 05:25:24 PMTest port and ground wire are present at all my ProFiles and all my spare controller boards. The piggyback Z8 have been used for the first one or two years, then they were replaced by mask ROM parts. There was a service note that required all piggybacks to be replaced with masks whenever a ProFile came in for service.

I second this. Not all of mine have it, but I'd say that at least half have the diag port and that wire. Not sure about the little notch on the board, but I'd assume it's there too!

Hi all, I'm working on repairing a Lisa 2/10. The machine appears partially alive but does not produce any usable video output besides a raster and has the clicking speaker. I've removed the floppy and widget drive for testing.

I have already did a recap on the CPU and I/O board and have had no change in behavior. No damage to the boards as this does not have the battery pack.

Also plugged in an Apple /// monitor and it behaves basically the same as the internal one.

Looking for some advice as I'm wondering if this is video RAM related, I did reseat them but no difference.

Current symptoms
• CRT powers up and produces a stable raster
• Screen shows horizontal bands/interference but no text or graphics
• No startup message or errors on the screen
• Constant click when powered on
• Behavior is unchanged even with RAM removed, clicking stops when I/O board removed

Troubleshooting done so far 

CPU
Reset line tested with oscilloscope:
Goes high at power-up and remains stable
Drops correctly when reset button is pressed
Clock signals appear present and active

ROM
Both ROM chips removed and verified using programmer
ROMs match known good Lisa ROM

Also reseated the video rom, when removed raster went away but speaker clicking continued

Interesting... After refurbing more than a dozen 5MB profiles, this is the only one I recall seeing in this config. Go figure!

Came across a non-working 5MB ProFile with an unusual controller board inside. It has the LLF kit's Z8 with piggyback ROM installed, but the more interesting part is the board itself. There's a diagnostic port (?) of some kind next to the LED power connection, a hand-soldered ground wire near the parallel port, and a curious notch in the lower-left corner of the board. Have not seen this version previously and thought folks might like to see it.

Yes and no!

The FIRST one I saw was a demo of VNC (VNC server?) Afterwards I did see yours. So YES you are somewhat to blame for me having a LISA...

Did you use an Xlerator? Details please!

Are you referring to my shaky video?

Hello!

Watching a video of remote control by and of a LISA was one of the last straws that led me to getting and repairing one.

I am still not where I need to be though so looking for some help.



I have installed Timbuktu 1.0pro on my LISA and my LC III+

(LC has 7.5.5, LISA has 6.


I can connect to and control my LC III+ FROM the LISA which is GREAT!!!!

When I try to connect to the LISA from the LC the LISA freezes and requires a hard reset.

When I try to select IP connections (radio button) the LISA freezes and requires a hard reset.


Questions:

1. Does anyone have a working setup? If so can you please provide details?

2. If you are using an XLerator also, please provide details.

3. Does anyone have a copy of Timbukto for WINDOWS? I have tried to find a copy, but every link so far has taken me to spam/clickbait/malware sites. I did get one installer to download but the installer said it was corrupt.

Thanks!!!

The boards look like they're done with manufacturing now, and are about to go into assembly. But they've been stuck on the "final inspection" stage of manufacturing for like 3 days now, whereas this normally only takes a couple hours, so I'm starting to get worried. I sure hope the inspection didn't fail. Then we'd have to wait ANOTHER week for them to remake the boards. And remember, the boards I need for school are caught up in this too!
