Please help testing: New loader release imminent
Hi,
before releasing the next version of my loader, i'd like to make sure it works alright on random actual hardware.
Basically i only need to know on which hardware combination it fails.
Some information about exotic hardware which works with it (anything that is not 1541/71/81) is also appreciated.
I'd be grateful for all reports.
The test images can be found here.
Thank you! |

You can use your favorite filecopy program to put all files on an SFD-1001 disk - the files are the same on all images.
Since the loader uses the KERNAL fallback for all drives it doesn't have custom code for, it's not faster than loading normally on an SFD-1001. |

Gunnar, yep, v120b works alright with c128dcr+1541u. |

Tested version 123 on:
Old vc-1541, worked
Oceanic-118, worked
Enhancer 2000, didn't work. Hung immediately on 'pollblock' |

Not tested on my SFD yet, as for some reason my MSD IEEE interface won't let me use a serial device #9 together with a IEEE device #8 :( |

Hoxy: "Enhancer 2000" is a weird beast, haven't known it until now. According to the internets it seems to fail with a lot of custom loaders, but i'd like to know why and maybe even get the loader to work with it.
Can you make a ROM dump of its firmware? Would you help me get the loader to work with it?
The MeatBall: The interface may have a way to switch #9 to serial. Some come with physical switches for that, but i suspect those who don't have a BASIC command for that or at least some magical POKE. Do you still have the manual? |

As you say, it's weird, that's why I just had to test your loader on it :)
If you really want to try to make it work on it, I'll do my best to help you.
I'll get a ROM dump to start with then. |

I've got the manual (http://c64disks.hvilket.net/MSD_C64_to_IEEE-448_Manual_and_Note..) and it has a small type-in that's supposed to let me use serial and ieee devices simultaneously, but I've had no luck in getting it to work :( |

The MeatBall: Can you send me the driver code which is active at $9c00..$9fff after enabling, or the contents of the IEEE cartridge's ROM, or the contents of the disk the manual mentions? (The more, the merrier :D)
To work with the current loader test build, the driver code must be relocated to somewhere in the $c000..$cfff range ($cc00..$cfff, as in the manual, should be the safest option). Once it's working, i can add some code to automatically relocate the driver if need be.
Getting #9 to work as serial is needed to actully copy stuff to the MSD drive, but maybe i can help you there using VICE and the driver code. (As i understood, most if not all IEEE-488 interfaces look pretty much identical from the software side and only come with different driver code - so VICE might be able to emulate it.) |

Right, how do I save $9c00-$9fff from basic? My 1541U doesn't work with the CIE, so I need to do it from basic :)
Also, there is no disk, nor do I have the ROM dumped (but I'm pretty sure I saw it online somewhere when I was looking for the manual). |

?peek(40959):poke43,0:poke44,156:poke45,0:poke46,160:save"1",8,1
note down the value printed because must be patched in the resulting file "1", the byte at $9fff will be replaced by the byte "1" (the file name) |
