Interesting. I still have yet to fix my 3400c but I just figured the battery was completely shot because I also tried running the original firmware but the 5300c just acted as if it wasn't there.

You can either get a super cheap SIL card that, hopefully, has a large enough ROM to do the following https://68kmla.org/bb/index.php?threads/silicon-image-sil3112-flashing-easier-way-using-flashrom.7013/ Or one the preflashed ones on eBay for a little more

Perhaps the controller is on the way out? A cheap PCI SATA card should actually preform better if you have the open slots to support it.

You are correct. I couldn't find anything online about it so I wanted to make sure before I went prying on it. Thanks!

Is it possible to remove this coin shim that sits on top of the G3 die? It moves freely on top so whatever paste was there is long gone now.

While I wouldn't guarantee it, they do seem to be compatible on the surface. Hopefully someone else can confirm.

I saw that too but when they take the 3400 board out you can see it matches mine and the datasheet (https://www.datasheetcatalog.com/datasheets_pdf/K/M/4/1/KM416V254DJ-6.shtml) reports them as 256k x 16bit for 1MB of vram. 800x600 at 16bit color just barely fits in that frame buffer.

Here's a front and back shot of the 3400c. Very very similar layout.

Mac Gurus and Low End Mac report the 3400c as having 1MB and based on the board layout that makes sense. To say I'm a bit confused would be an understatement. The 3400c uses different pin spacing from the kanga so it's unlikely to be able to use them.

According to the datasheet you have 2MB. 256K x 16 is in words not bytes. Double the 256 to get the byte total. Unless I'm mistaken. https://www.versalogic.com/wp-content/themes/vsl-new/assets/resources/support/pdf/65550.pdf

I'm now questioning my own repair on a 3400c. It has two 256K x 16 chips next to it's 65550. Does the 65550 have it's own internal memory?

I've gotten lucky a few times from eBay. My iici has a Daystar 50MHz 68030 card and my Powermac 7500/100 a XLR8 G3 upgrade. I also managed to snag a DLSD 17" from a lot of powerbooks that showed up in nearly flawless condition with a still functional battery. Each time felt like I stole something.

Oh. My. God. I tried every combination but I expected to see something before the OS booted (I have 128MB in my iici so it takes an eternity to boot) and never did. I let it boot on 678 and boom there it was. 1024x768 millions of colors. You have no idea how mad I am at myself but also ecstatic...

I'll have to build this sense code adapter tomorrow to make sure it works on the MX (I'm sure it does)! Absolute genius life saver. I thought I was going to be stuck with this thing only semi-working!

Yup nothing. Every other type 7 code works (Sense Codes) to certain degrees on an old VGA LCD. Since tattletech crashes when using that RGB 19 (1024x768) dip switch setting it does appear to be doing something.
