I've spent almost a year poking at the motherboard on my 2400 to get the extra VRAM I've added to work.
Zero success. I've fried so many motherboards, blown a ton of surface mount fuses, let all the smoke out of the C&T6550 chip twice. If you get the specs on the Chips&Technology 65550, the can use VRAM in a few different configurations. It looks the the extra spots on the 2400 logic board was for a different 1meg VRAM config using 4 256kb chips instead of the two 512kb that shipped. It also doesn't help that the stock 2400 LCD screen doesn't support millions of color very well (only 6bit per channel versus the 8bit minimum needed for clean display of millions of colors) It also help even less that the C&T 65550 is dog-slow in 24bit color mode on the 2400 because the 2400 bus is optimized for 16bit color mode. I've had limited success grafting on a C&T 65555 into the 2400 with a replacement LCD display. My little FrakenComent, if you will. A 'borrowed' 1024x768 LCD display of a super-sub-compact Sharp laptop, 4 megs of VRAM, 250mHz G4, embedded MPEG2 decoder, S-video out and a hacked together Li-Ion battery. Too bad it doesn't run for more than 15 minutes without hard crashing and getting stuck in a GLOD and blowing a few component. Caught fire once, too ... >Me too. If the upgrade were as simple and possible as the man was saying, >I'm sure many of us would already have done it or had it done, right? > >BobF -- Peter Liethen - [EMAIL PROTECTED] - http://www.liethen.com ---------- Duo/2400 List, The friendliest place on the Net!
