| Feature comparison of the various SCSI to SD options? |
Posted by: Realitystorm on 2024-03-23 13:01:36
I'm planning to update my downloads page and add some new guides to my website for the various SCSI to SD options that are now on the market.
As a first step, I'm creating a list of current options and doing a basic feature comparison.
Reading through the guides for BlueSCSI and ZuluSCSI, I found it difficult to confirm what features went with the RP2040 versions vs. the older non RP2040 versions. So I decided if the guide didn't say, it was a feature available on both versions.
I also wasn't sure if the ZuluSCSI had toolbox software similar to the BlueSCSI and the MacSD.
If any of you have a chance please take a look at my list and comment here or on my site if there are any additions or changes you recommend.
I also plan to make a page for the HD20 (floppy port connected) hard drive options in the future. |

For the RAW format, wouldn't it be formatted as Apple Partition Map with one or more partitions? Is no partition map an option for SCSI devices?
Does CD format mean 2352 byte blocks so it could be an audio CD or mixed data and audio tracks? |

Does CD format mean 2352 byte blocks so it could be an audio CD or mixed data and audio tracks? I made some changes to try and better describe what RAW is vs. the image files stored on a FAT32 or exFAT formatted SD card.
For CD-ROM image files, the MacSD documentation described in detail that it supports BIN/MODE1, redbook/audio and mixed-mode disc images. But I'm note sure for BlueSCSI or ZuluSCSI. BlueSCSI states it supports BIN, but I could not find any detail. ZuluSCSI states ISO and .img, but I'm not sure if .img is the same as .bin |

It is not.
BIN is a 2352 byte per sector rip of an entire disc. The track layout is described in a separate CUE/TOC file.
ISO is a 2048 byte per sector rip of just a single data track. The extra 304 bytes of error correction, sync, and other data are discarded in this format.
The IMG and TOAST images I've encountered were ISOs.
I'll take a look at your new page and get back to you. |

I did a bit of a reword on my list to include Floppy Drive and HD20 replacements and a short summary of what SCSI is and key points that someone know to using old Macintosh Systems would need to know. Feel free to comment here or on the page if any of the information I have is incorrect, or if I'm missing any options. |
