It's possible upgrade Indy XL 8 bits to 24 bits?
- Thread starter kikems
- Start date
Depopulating parts is a nice easy way to create 2 products from 1.
The downside is that there could be other differences, that tell the system how to recognize the difference besides just more memory.
8-bit is a palette format and 24-bit is RGB Framebuffer, so there is probably at least 1 other difference. Could be as small as a resistor jumper or as large as a different version of an IC, just have to look really close.

I think there were other support chips, but who knows. I think this has been covered before, so you might want to search around the net on old IRIX/SGI archives for the answer. You're not the first to think about it 
XL24 cards are pretty cheap tho so you might just want to try and find one first.

Old newsgroups are awesome. You can search them on Google, cause google stores all bits in the universe, and mines it just like it mines your brain

Yes and no. You will need to solder on a bunch of RAM chips,
and a couple of SGI memory ASICs in very fine pitch surface mount
packages, and a few hundred discrete resistors and capacitors,
some in 0603 package or smaller. The only place I know to get
the ASICS is from another XL-24 board.

Most of the SGI resellers have them, they should run under
$100. Check in comp.sys.sgi.marketplace
