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.

I'll give that a try. It's been a long time since I've used Wireshark, but hopefully I can fight my way through! My bet is on the RPi Pico network stack being the culprit. If that turns out to be the case I doubt there's any remedy possible.

What happens when you connect a drive to the rear panel DB-25 connector?

I've been struggling with Appletalk under System 7.x when using the emulated Dayna SCSI/Link device in ZuluSCSI (problem might exist in BlueSCSI as well, but I do not own one). A real SCSI/Link hardware interface (connected to my ethernet network) shows Appletalk Zones in the bottom left of the...

That little fan has a noticeable whir to it, but it's better than an overheated CPU. At 40 MHz. it was getting uncomfortably hot when run without forced air flow. It probably has a lot to do with the die-stepping of the CPU. Some of the later 68040 shrinks were better able to deal with higher...
