[edit] Drive two works, it must have been a fluke World of Commodore crashed. Arte by Sanity boots and works 100%. [edit] Thanks to the superb support at AmigaKit the drive is up and running Arte! as I type this. The head was just stuck, nothing more. [ Show youtube player ] |

I replaced a broken Epson SMD300 with a modded Alps DF354H, rev.121G.
I followed these instructions: A: Change DS1 to DS0 jumper pad. B: Cut trace from pin 2 of connector. C: Cut trace from pin 34 of connector. D: Solder a wire from pin 34 of the connector to RD pad. E: Solder a wire from pin 2 of the socket to pin 5 of the chip. F: Solder a wire from HD2 to ground. Works fine, but I cannot use my external A1011 drive as DF1: when this one is DF0:... It shows all disks as BAD. Maybe that's because I skipped step F (disable HD detect)? Who knows... Anyway, I then cut the top of the drive case with my Dremel so it would fit, and removed the eject button from the Epson, and adapted it to the Alps drive; so it really looks 100% stock! |

Has anyone tried modding the AmigaTech a1200 supplied Panasonic JU257a605p to be a proper Amiga FDD?
I believe there is a jumper wire on the bottom of the a1200 mobo that needs to be removed once a proper amiga drive is installed but I havent had a chance to take the ju257 apart to see if it looks anything like the ju256 i've already modded. PS, found these instructions on AmiNet but wondering if they are 100% accurate for an AmigaTech supplied ju257? http://aminet.net/package/docs/hard/ju257 EDIT: Just found this info http://www.softpres.org/article:hard...u-257a605p_fdd and the mobo mod: http://www.softpres.org/article:hard..._fdd_connector Last edited by dJOS; 09 April 2013 at 01:41. |

Are these Modifiable?
Hi Guys I managed to locate some old Panasonic and Sony drives:
2 x Panasonic JU-256A048PC (PCB Scan - See Attached "Panasonic JU-256a048PC - small.jpg") 1 x Panasonic JU-256A048P (NO PCB Scan) 1 x Panasonic JU-256A888PC (NO PCB Scan) 3 x Sony MPF920??? (PCB Scan - See Attached "Sony MPF920 - small.jpg", but I don't have what 920 model it is) Are you guys able to give me any advice on if they are modifiable ? * The JU-256A048PC looks pretty close (simiar looking ic) to a JU-256A198PC photo I have seen that someone modified on the web. (See attached "Forum Panasonic JU-256a88p - small.jpg") * The JU-256A048P im not sure about this one as I dont have a PCB Scan. * The JU-256A888PC is hopefully the same as a forum post I saw with a pic of what they call an JU-256a88p (see "Forum Panasonic JU-256a88p - small.jpg") which im hoping was a typo and they missed an 8 and is a JU-256A888PC (triple 8). * The Sony drives look very similar to a post I saw with this mod (See "Forum - Sony MPF920-z-161 - small.jpg") I also attached a pic of "Forum - Panasonic JU-256A198PC - small.jpg" from the forums. It may be closer to one of the two I don't have pcb scans of. Cheers Vot Last edited by Vot; 30 April 2013 at 16:14. Reason: Woops Forgot the Pics! |

check this thread for more drives info... http://eab.abime.net/showthread.php?t=43265 There are a lot of revisions of drives using same part number, its best to compare to see if the same chipset is being used to determine compatibility and just trace the connections to see if you can clone it onto yours. ALL PC drives need to be converted from DS1 to DS0 in order for the Amiga to recognise it and then of course the other signals. Not all drives will convert, its the luck of the draw |

I would steer clear of these.. At least don't do any writing with them. Those flimsy sheet metal drives are out of alignment in no time.

Looks like I did make a typo, the panny is a 888 not a 88 as I may have written - I makes a great Amiga drive too, quiet and reliable. |

Working Panasonic Drives
ju-256a108p
ju-256a178p I can confirm these two models can be modified to work. Tested with sanity artae. I will edit this post in a few days to show pics of the mod for both. |

Have you verified this drive with the sanity artae demo?. The pic I got I think from your post when you modded it shows you bridging pin 34 to 32. On all other mods pin 34 is bridged with pin 30. Just checking as I may be able to get my hands on the 888... |

JU257A607P Rev F
Hi guys despite previous posts it looks like you can get the 257A607P working (Well Rev F atleast).
If someone can post a good pic of this models pcb I will annonate it with how to mod the drive. unfortunately I had to do a bit of investigative work to get this going and cut a pcb trace in the wrong place.. ended up having to solder directly onto the QFP to access the pin. Trust me you don't want to have to do that at home. If you just cut the traces differently its fine.. no harder to mod than any other panny. I havn't tested it with sanity artae yet because ive misplaced my floppy but it should be fine.. boots other games ok... just have to check the rdy signal with the demo. I will check it tomorrow and update the post. Tested with sanity Artae. Works like a dream... Last edited by Vot; 09 May 2013 at 10:02. |

re the bridging of those pins, I'll need to double check why I did that - it might have actually been a mistake that I never caught because it worked. |

Does anyone know if this mod or a slight variation on it can change my NEC FD1231T into a mode-3 floppy drive? I urgently need to get my hands on a mode-3 compatible drive and the fastest way would be to just modify what I have at hand. |

Samsung sfd-321b failure
Yesterday I modded Samsung SFD-321B (REV WT-02). It wasn't used for years and I thought I could give it a shot. I sucked DS1 blob and created some blob of solder for DS0. Then I desoldered jumper from DC and soldered it to RDY. I accidentaly lifted the DC pad in the process but then I glued it and checked for continuity with the integrated circuit. Then i soldered the wire from DC pad to the pad that goes to pin 2. Here goes the strange part... I connected the drive to my Amiga 600 and succesfully loaded Enigma by Phenomena (lovely demo). I was playing the demo for a minute or two, everything was fine. Then I turned off the power supply and at the same moment smoke came out from the floppy. I think I fried the IC (fire symbol on the picture). It smelled very bad. I don't know if I screwed up or am I just unlucky? |

Finally the Sony MPF920Z-171! Thanks to a local friend (Alexandre "Tabajara").
1- Cut track near pin #34 to insulate it. 2- Follow the picture. |

Hi
Using Kippers mod (here http://www.kipper2k.com/amiga/teac.jpg) I successfully modified a Teac FD-235HG drive to work on my Amiga 500 - all good. Thanks much to all. |

right. SFD-321B time. this is a T series
heres the mod accordingly it kinda works....so power on the amiga....both FDD and power lights come on......drive fires up, reads disk but is VERY slow. sometimes it does read. of note, the FDD light goes out, when the disk is inserted /reading, but, the LED on the front of the drive works fine |

Have you switched from DS1 to DS0? These drives work perfect on amiga.
