+60k ram expansion
hello everyone,
i really would like to build this +60K RAM Expansion here - i found some of the parts online already (us3-us6) but what are us1 and us2? just by the number i can't find anything to order online. and u6, u7, u10 and u11 are the chips/pins to connect on the c64, right? (i don't need to get us1 and us2 from a c64, do i?) also it looks like i need to cut a trace and remove a resistor?
and the most important question: this is the +60k ram expansion that will work with Turbo Assembler Profesional V1.2 [+60K] right?
thanks for any help or pieces of advice!

lol ok nevermind - i found some 4464 dram chips on d-bay and the rest at a local electronics store. the rest seems to be the way i thought (Ux are on the c64 mobo and i need to cut a trace and remove a resistor)
happy hacking everyone!

sorry for the typo :-D
anyway, reading this again, it could sound a little harsh but wasn't meant like that :-D
sometimes the answer is just "very" close :-D
a memory expansion without memory on board looks a little bit strange :-D
hope you get it working and enjoy it

Did some checking on that extension when trying http://rr.c64.org/wiki/Extensions#60k_Memory_Swap
Guess I will stick to REU and such though :)
