" I don't know how to make a cg6 do double-buffering anyway, except via
" colourmap trickery.
" The TGX/TGX+ are compatible with the GX/GX+ but are faster and support
" more resolutions. (The T stands for Turbo). The GX/TGX have 1Mb of
" on-board memory, which gives them a maximum resolution of 1152x900.
" The GX+/TGX+ have 4Mb of memory, which is used for double-buffering
" and optimisation, and has a maximum supported resolution of 1600x1280.
" Note that unlike some PC graphics adaptors this memory CANNOT be used
" to give more than 8 bit colour.
" 501-2253 - TGX Plus. Older model. Same chip and names as TGX (501-2325)
" 501-2955 - TGX Plus. Newer model.
i'd like to know how the Integrix SXT200 does
also from the fb faq:
" Here is the appropriate voodoo for several supported resolutions. Note
" also that this will only work for the TGX or TGX+.
" 1600 x 1280 at 76 Hz 216000000,101890,76,24,216,280,1600,2,8,50,1280,COLOR,0OFFSET
i have a pair of tgx+ and a couple of tubes capable of 66hz refresh,
but none that will do 76hz.
