Catweasel and WinUAE (and other emulators)
I've been toying with the idea of building a new PC, partially to replace my Amiga 3000, but more specifically to emulate 8/16-bit computers in general (My collection has gotten to the point where three desks are occupied with five computers, and I have others that I don't have room to set up, and others that I want to acquire, but don't have room to even store!)... and while thinking of what to put into this new computer, I thought it might be a neat idea to put a Catweasel in there so I could actually use real disks.
Now of course, all this is silly and pointless when I can just fill a hard drive with disk images, but there's something authentic and slightly clever about being able to read original disks that I really like (I'm also considering hooking up a tape player to the audio-in to see if I can play Spectrum games through it... yes, I am insane). I can't seem to find a lot of information on this though. From what I gather, WinUAE and VICE both support the Catweasel... but there's not a lot of documentation. This page seems to be all the information available for WinUAE, and VICE has nothing more than vague references, and the official Catweasel page doesn't even mention the Mark IV... so I'm having difficulty deciding if this is going to be worth the investment, or if it'll just be a big disappointment. I gather the community here has more experience with these device than most, so maybe someone here can answer my questions:
Even if I can't use the Catweasel the way I want, I might still use one anyways... but it wouldn't be quite as valuable to me. Last edited by Ze_ro; 03 August 2010 at 09:23. |

It won't be trivial to implement, not sure if anyone bothers with it. (It would be interesting task but also extremely boring..) |

IMO the catweasel has only one use, and that is to archive all of the unprotedted disks you have to the adf format. Then it becomes redundant unless you constantly get other disks to archive.
My Catweasel MK3 has sat in the drawer for over 2 years, never needed to use it, if you want it pm me. |

Best solution for this is build a mini itx system to gain some desk space. Their small, cute and save having a massive tower or desktop system hogging your desk space (or floor space).

So how does it actually work then? Reading the document I linked to earlier, it seems to show up as CAT:... but what can be done with it? Will it read and write just as if it were any other device, or is it limited to simple file copying?

Also note that Catweasel can either read/write to disk from internal RAM or internal RAM is copied to/from host PC, both can't be done simultaneously. Which makes real-time emulation practically impossible (without keeping emulation paused most of the time..) For example some copy protection might do this (just an example, there are many similar situations) - read data until something specific happens (data matches some magic word, index sync, whatever) - switch disk side but keep reading Disk side switching should be instant but because USB and software is packet based, some data is still in buffers that must be flushed. Now we have the problem, it takes some time before disk side switching gets to the drive and first data arrives from drive. Only 100% compatible solution is to pause the emulation until data arrives. (we are again in "sync") Copy protection is happy. User might not be happy enough. (especially if music or sound was playing) Or we can keep emulation running Copy protection is unhappy ("gap in data? that can't be original disk") and user is very unhappy (game didn't work) Standard disk accesses don't need that kind of accuracy and would work just fine in most situations. |

So copy protected discs are pretty much a wash, but unprotected stuff and cracked games (that don't use their own fastloaders or any custom methods) should work? |

anyone know if the latest VICE or any other 64 emulator for the Amiga supports the full SID chip support on the the latest CatWeasel ...looks cool that you can can plug in a REAL SID in the CatWeasel
I assume you can create your own real disks as well to be used on many retro machines with the CatWeasel |

Yes. Create empty floppy disk images and fill them with your choice of OS/programs/files using your favourite emulator and write the images to real disks using the Catweasel.
