Isn't Chipram access still slower with an ACA12xx?

I believe subsequent releases were, similar to your Microbotics or my GVP 1230 (max 4.5 MB/s). The early ones (1230/56) were like the old Blizzard and Apollo 1230's, up to 7 MB/s. There are games that will show the difference, though I didn't find many.
Actually, pretty sure chipram access with the Apollo 1230 is faster than it is with the original onboard '020. |

Yep, my MX1230A loads Turrican WHDLoad much faster than my ACA1232 in my A1200, I think Jens mentioned the ACA is Asynchronous.

Use to be Novas old card ;-) To be honest haven't needed more than 64MB when it was still in the wedge case, when I towered it I used other options for more RAM :-) |

I know I won't be selling my BPPC, unless it's a trade for one that's same spec with a SCSI kit
@lurch: I've seen the weird ways folks have gotten their FastATA to fit! Elbox even sell a riser kit for the Mediator to allow more space underneath it, but it raises everything so the PCI cards get raised too meaning you have to find a way to screw them down either with spacers and longer screws or screwing standoffs together to get the right height! Not sure I want to to go to that much hassle, some of those angled sockets just don't look secure enough to me!! |

Have now bought a Blizzard 1260 + SCSI Kit, both with 64mb and 060 @ 50Mhz!
Waiting for delivery, but in the meantime what SCSI HDD stuff can I connect internally and what adaptors/terminators/cables are needed? I've read that LVD/SE drives are needed and active termination just need to know what drives to look for now. |

Most straight forward: narrow 50 pin drives, cable and terminator.
You'll need a custom cable in any case, as the Blizzard doesn't support internal drives per default. It ships with a Mac style connector for a 25pin external drive. |

Would a SATA-SCSI adapter be OK as finding a 2.5" SCSI drive is next to impossible, so want to use a standard 2.5" SATA HDD/SSD!

Sure. I wonder if you can find one in the 2.5" form factor though.
In any case, internal SCSI drives without a tower case is going to be a hack. I remember the ST51080N was a really thin 3.5" disk that fits in the desktop A1200 just fine. |

Found this, a 2.5" SCSI drive with SCA connector: http://www.ebay.co.uk/itm/IBM-e-Serv..._HardDrives_RL
and an adapter like this: http://www.ebay.co.uk/itm/Computer-8...-/181608506857 Then it's just a custom SCSI Cable from Blizzard to 50pin. |

For a internal SCSI drive i would just go directly for a CF Aztech or Powermonster, they really arent /that/ expensive.

Too expensive, like the Acard ones!
There's various adapters available to convert drives to different connectors, like this Male to Male HD68 to 50pin adapter Getting a compatible drive is the key and a 26pin IDC to 50pin IDC cable. |

Those SCSI adapters really are a pain today. SATA/IDE -> SCSI is expensive, while SCSI drives old
If you're serious about Amigas, and are going to use them for years to come, then those expensive converters are sadly the best option, because you're going to be stuck with old drives otherwise. This is really the main reason why I stick to IDE on my A1200. Cheap converters and cheap, new drives. |

I have not seen cables with SCA connectors or IDC SCA connectors to this day. Perhaps they exist? Edit: Well, I just had to google it and what do you know: http://www.cs-electronics.com/images...0-xx-large.jpg Perhaps get one of those cables and splice the power connector + 26 pin SCSI kit connector onto the other end. Then there's the problem of termination. SCA drives don't have termination or ID jumpers.. I guess you'll need to involve the narrow -> SCA PCB in any case, then you don't need to mutilate the extension cable. Post pics when you have it running. Quote:

I'd like to get a FastATA but have an Indi AGA to fit and fitting a FastATA is too problematic with an Indi AGA in a desktop, I know it can be done but i'm not too keen on attempting it! SCSI is the next logical step as it all fits onto one card but still needs some messing about to get working.
Have to wait for the 1260 to arrive first, once I've got it fitted + SCSI then the fun and games will start! |

@Jope, or should that be 'Joke' as I guess you post was meant to be These are the replies that clearly explain why certain combinations are problematic, thanks for pointing those out!
This is also a 1D.4 board that has E123C and E125C still on the board, so will find out if I get instability once the 1260 is connected. Some people have had no issues with the Blizzard 1260 on 1D.4 boards and some have, hope i'm one of those that have no issues! |
