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.
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.

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.
You wouldn't mind pulling the ROM off of your LX would you? RGB 19" setting is actually crashing the system when I try to open tattletech displays with another display plugged into the built in video. I've tried all the settings above with a no sense adapter with no luck. Nothing in monitors or...
I don't have the manual actually. Information on E-Machines products are next to none at this point. I have seen those cables I just don't get why a VGA monitor wouldn't work. The tables I've found have multiple configs which do include a vga setting. Even if we ignore that, it specifically...
We've tried a no sense adapter but with zero luck. Is that sync separation different than what is standard on mac DA-15? On that it is straight through to VGA for sync signals.
