What were your thoughts on this man?

well i can verify the 4 meg's from the dead powermac 6100 board worked!

the video does seem faster too. the after dark fishy screen saver that is on there… seems to flow more smoothly.

how far do you think we can push this?

so there is 8 spots for ram chips…

one thing that confuses me…

this doc:

http://tim.id.au/laptops/apple/legacy/macintosh_iisi.pdf

it says the IIsi comes with 2mb ram.

but any IIsi i have ever seen only has one meg onboard.

Oh unless it came with one onboard and 4 256k's ….

also Everymac: http://www.everymac.com/systems/apple/mac_ii/specs/mac_iisi.html

Details: *Onboard video is capable of supporting a maximum resolution of 640x480. If the optional NuBus adapter card is installed, a second video card can be installed to support a second display. The NuBus adapter also provides a 68882 FPU.
So looks like I got the 640x480 just by upgrading the ram to 4mb. interesting.

i was able to get 640x870 but it was pink only…. well now its blue only… (I'm booting 7.5.5 back up)
