How to use +60k expansion
Yep, as easy as that.
How do I address that extra ram?
(In fact I'm more planning to build a +60k compatible expansion, but that's another story. It's easier for me to build stuff if I know how they are supposed to work...) |

A bit off topic I guess but I suppose that actually Action Replay / Retro Replay internal ram is most popular memory expansion. Not useful if $dexx memory can't be used but anyway I though it was worth mentioning here as it must be more popular than +60k. It's also trivial to use. |

Sure, I have 1541u and IDE64.
I mostly use the second one, where $dexx is occupied by lots of io-stuff like ethernet, usb and whatnot.
$d100 for enabling +60k is simple enough.
Then I have lots of free io-space to implement page selection too. The only problem is that I don't know if my cdpld (3064) is powerful enough to do that stuff. I could use more... But a +60k is easily done in one chip. (plus memory, or the built in memory of a c128) |

may I ask: what software are you going to use which takes advantage of the +60k? |

Quoting hevosenlihaSure, I have 1541u and IDE64.
1541u already has a REU inside with 16 MB RAM, and 1541u also has Retro Replay cartridge emulation which has 32 kB of RAM.
I don't see why you need that +60k expansion.

My guess is: for the fun of it :) |

I can't use the 1541u at the same time as the ide64...
for me the 1541u is nothing but a floppy emulator. |

Why not use a PC crossassembler and 1541u ethernet to transfer the assembled code directly to C64?

mainly because my 1541u doesn't have ethernet.
but my ide64 has usb, and that way I can mount the pc right away, browsing the pc in the wonderful file manager built into ide64, just hit enter on the newly compiled file and it's started in a second.
yep, that's the thing with ide64, it makes the good old computer behave like a modern computer.
for me the 1541u is nothing but a floppy emulator for compatibility with old/bad stuff, which may not work on my c128 anyway.
turbo assembler is way better to work in than my slow asus eee pc 900 with too small keys...

old/bad stuff? Basically everything with an IRQ-loader needs a 1541 emulation. Has nothing to do with old or bad but with the inability of the standard C64 kernal to do anything else during loading.
