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...) |

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.
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.

sure, that's "bad" stuff, relying on the irq loader.
check covert bitops loadersystem, with fallback to "kernel" routines if current device isn't an IEC one.
It's like releasing a simple multipart prod that require an ide64 just because I don't want to include an irq loader. |

You can't do a "kernal fallback" in a trackmo. |

And the real point with a trackmo is what?
Extra space? I don't buy that one.
Not that 1541u is a bad thing, it's good at what it's doing.
But how good are floppies anyway? ;)

The point of trackmos is that there are no loading breaks and all the loading is done while stuff is happening on the screen. |

...At least the main advantage trackmos had over normal "screen goes blank and/or flashes while loading- demos" was to have something shown in the meanwhile.
Unfortunately most trackmos ever made featured dull loading screens and stale design to cover up for the need to fetch data. :P

"sure, that's "bad" stuff, relying on the irq loader."
c64 standard for running stuff is: 1 c64 with 1 1541, and that will not change to ide64 or whatever until the end of the world. No support for rare HW, right.
"But how good are floppies anyway? ;)"
how good is using 82 hardware in 2009 anyway? you should consider doing stuff on pc. :)
"for me the 1541u is nothing but a floppy emulator for compatibility with old/bad stuff"
so c64 software for you == old/bad stuff ? really go for pc then ;) |
