Basically, it means swapping the CPU, replacing the 6502(A) with the CMOS version 65C02. That adds a bit of speed and a few extra instructions. Also, ROMs must be changed. The system ROM, which is the boot up routine, etc. in the firmware, and the Character Generator. The Char Gen. has the MouseText characters in it. This is the part that is a little difficult. If you do it yourself, you will either have to get the upgrade kit from a dealer, which they usually are reluctant to do. Apparently, they have an agreement with Apple to do the installation themselves, and not give the kits out to the custormers. But, I have heard of people coaxing the dealer into letting them do the modifications themselves. Of course, buying the kit from the dealer is likely to cost you the same amount as to having the dealer do it for you... to actually save money, you will probably have to get the ROMs bootlegged. Which is illegal, and if not that, immoral. (I doubt that it's fattening though.) :-) This involves copying the ROMs in an enhanced //e, and burning it into a blank 4164 EPROM. You will need an EPROM copyier for that. So, in my opinion, $70 is reasonable, unless you own an EPROM programmer, or can borrow one... in which case, the parts themselves will cost less than half that. --Tak --------------------------------------------------------------------------- ++ Dictionary of Old English == University of Toronto == Toronto, Canada ++ Internet: amos@csri.toronto.edu oldeng@gpu.utcs.toronto.edu BITNET: oldeng@UTORGPU ---------------------------------------------------------------------------
