Odd. I never saw a single problem with the one you sent me. I must lead a charmed life.

Voltage trim adjustment on some supplies (e.g. Astec and others) was done by adding / clipping resistors.

@Oliver_A - Where are you located?

I second that recommendation. I have about a half-dozen Pico Slims sitting on the back of classic macs. Appletalk over Wifi has some minor issues, but it basically works and makes it quite easy to move files around.

That would be helpful. Much as I'd love to have my 68k Macs work with HFS+ on System 7.x trying to follow along with this thread gives me a headache. Short of a plug and play solution, I'd really appreciate a quick recap of how to mod a 68k system.

Wow. Just wow. I'm glad it worked out in the end - but sorry your wallet took the hit.

None of my LCD displays will sync to the 30video's 1024x768 timing. Talked to Joe and it's a known issue.

Did it go to anyone we know?

Sorry to say I never did. However, I'm currently fighting with ZigzagJoe's 30video board in 1024x768 mode. The Extron is very unhappy with the timing. This is the first such case I've seen where nothing would dial in a proper display. The next time I have a Plus or 512 on the bench I will...

Here's a bunch of photos and schematic: https://bit.ly/extron-bt

I'll second the suggestion for the ROMSHIMMs. Fixed a bunch of annoying problems on one of my SE/30's. Not shipping to the USA at the moment because we're too busy winning.

Why not do it this way? The LR501 battery has more capacity and three of them fit without an adapter. The Excel battery is simply (3) LR501 with spot-welded strips between them.

Glad you have it cooperating!

Those logic devices are fused PAL's. I think the logic has been reverse engineered. Apple typically blew the security links, but it may be worth a shot at reading them out on a suitable programmer.

That was one of my first theories, but a programmer's button reboot behaves the same way.
