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...) |

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. |

VDCAsm-128 V1.0
read the note file in the release.
btw there was a v2 version iirc which is missing from csdb... |

Good point. The same can be done with TMP + REU (not to mention the possibility of connecting 2 c64's together to run code on one and keep source on the other - looking at prices of CMB machines today not something impossible for even a poor coder). |

Quote: The point of trackmos is that there are no loading breaks and all the loading is done while stuff is happening on the screen.
You can do that with files too.
And in a way that is compatible with "exotic" hardware.
Even I have made that, and look at my coding "skills" ;)
Feedspister has music and scroll while loading the parts, from both floppy and ide64, and probably any available kernel patched turboloaders.
Why not use a decent open source turboloader that works with "everything"? |

REU doesn't work with ide64 :(
I've looked at some available roms for 1541u, but I haven't found anything that beats ide64 to work with.
My VDC is only 16k.
So I have the options to build +60k (3 chips including memory) or expanding the VDC ram if I want to keep my ide64.
Or crosscompiling on pc, loading the stuff over USB with ide64 drivers, as easy as "compile on pc" and "press enter" on c64. |

REU does work with ide64 just fine, just get yourself module port extender and more juicy powersupply...
edit: with C128 powersupply you just need moduleport extender, its powerfull enough to run ide64+1541U together. |

???
I was totally convinced they used the same IO space...
I just need to get (build?) a port expander then... |
