|  Re: ide64 - i dreaming about the plus4 version
IDE64 is not avaible now,"new version under development",until 2003...
Used prices are pretty inceasing on auction sites(just like C64 Supercpu..etc)
Btw IDE64 using DMA to reach memory,it has a very comlicated logic and own kernal.
Paging 64k ram "in pieces" onto internal ram area (i can't understand,how they do that).
But it should do all of this magic,because IDE64 can run many (modified) C64 whole disc game.
Supporting seq file handling,and many kernal I/O functions..thats are not possible without DMA,big buffers,some kind of "freezer technique",and so on.
MMC interface on user port would be a nice cheap alternative for plusy!! 
I have bulit some 1541/III drives,they aren't so cheap,because separated box,cables,plugs,cpu,display,lot of mechanical work...etc.
Maybe the simpliest DTV version,can be an acceptable solution.
