I recently got a performa 6116cd for my collection to replace my dead 6100/66 powermac. The board is dead on the 6100 but i did salvage the dos compatibility card (works tested in a quadra 650 i have laying around), the cache simm (256k), hd, cd, and simms. Anyway, since the performa is a copy of the 6100 but 6mhz slower, I am going to put the cache simm in it and the dos card. My questions, are since the cache simm is 256k, is it possible to put a 512k if it exists or even a 1mb one in it? I want this sys to run fast as im going to stick the dos card and even later yank its dx2 66 out and mb put a dx4 overdrive 100 in it. I did search and came across this link here but if I read it right you can use a 1mb in a 6100 right? The link is viewtopic.php?f=16&t=7627&hilit=powermac+6100+cache.
Also I did search and somehow stumbled on apples site listing various powermac models using cache simms, and the6100 is listed as only supporting 256k max? But i did find a cache simm for 7200 on fleabay, the 1 mb model, plus ill look elsewhere. So would that 1mb work or even a 512k? Also what about performance would anything above 256k make a real difference especially since i read about the onboard video?
Finally, of the various macs i've collected, this newly acquired one, a quadra 950, and a quadra 650/centris 650, need a new install of the os. If i've been reading correctly the 68k macs would be fine with sys 7.5.5 right? As for the performa since it has a cd i can go sys 7.5.5 or i do have a cd with mac os 8 retail for it, or even 9 if needed. But one thing is i dont have the diskettes for 7.5.5. From what ive read you can dwl it from apple but its 19 disks and u mount it on hd then install. But the 68k machines i have dont have an os install, is it possible to make the diskettes or full retail install disks from the apple downloads? I've seen someone selling it on ebay but its new unopened retail disks but a little too pricey @ the moment. One last question too, as for the dos card if i went with a dx4 on it, i have heard the 6100/6116cd have heat issues, this wont really fry the board or dos card right? The dx4 has a heatsink and all necessary voltage regs as it is an overdrive 100mhz.
Thanks in advance.
