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...) |

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 ;) |

gotta love that "it doesnt use kernal so its bad" babble from ide64 fanboys =)

Quote: turbo assembler
Not to be the one who criticizes all ideas but have you checked out:
1. Turbo Macro Pro with REU support
2. TASM ROM for RR/MMC Replay
3. Extra ROM with TASM for C128
There are many options that are quite useful if you want to code on the real thing. Unless you are coding for C128 strictly or C64 with +60kb you'r executable code with data will never exceed 64kb limit anyway so all above options look interesting.
As for C128 take a look at MMU registers. If you are coding in C128 mode than you can use it probably to simulate memory expansion.
Just my 2 cents... |

been coding for ages on a c128 in 64 mode, using lynchbit's TASM hack which compiled into the 64k VDC chip which is visibile in 64 mode, and then you can swap object<->src memory. |

Quoting Oswaldlynchbit's TASM hack which compiled into the 64k VDC chip which is visibile in 64 mode, and then you can swap object<->src memory Cool, didn't know this was possible. Where can I find info on how this works? |
