Interesting never heard of the AztecMonster. I have found that guys website. He still sells newer products, here 2 of them:

I have one in an Akai DPS12 . Never had issues with it in that use case.

EDIT: Mine is a SCSI to SATA variant .

This one https://www.artmix.com/SATA_SCSI_AZMN_II_1.html

Pretty sure artmix is known to take a while to ship. For the price, I don't think the AztecMonster would be worth it unless they've got exclusive features.

BlueSCSI is a clone of the ZuluSCSI with some added features. BlueSCSI seems to be more popular, and I do know some of the ZuluSCSI people aren't too happy about that because they did most of the initial work. There has been a fair bit of drama over the two in the vintage mac community, which I stay out of. Both projects are open source, so the BlueSCSI team didn't do anything wrong legally here.

The BlueSCSI team has been adding new features since the V2 came out though - notably, WiFi bridging over SCSI (although I think that's only possible if you're using a Mac for now). Most of the exclusive BlueSCSI features (like their file transfer program) are only for the Mac, so if you're running on a PC, there won't be much of an advantage one over the other I'd imagine. The BlueSCSI boards are cheaper though.

I've got a page on my website going over the options I know of: https://macdat.net/macintosh/upgrades/scsi_ssds.html
I need to update it to include the MacSD though: https://macsd.com/

Thanks for all the input.

Here's what I got:

(Mostly) Available:

• PiSCSI/RaSCSI - SD to SCSI via Raspberry Pi mod. Bulky but inexpensive if you have a Pi. SCSI 1 speeds
• BlueSCSI v2 - SD to SCSI - Fast 10 support, good price, limited availability right now but should return soon, MAC Features
• ZuluSCSI RP2040 - SD to SCSI - Fast 10 support. Hardware very similar to BlueSCSI but with a Pi 2040 chip integrated into the board. Slightly higher price
• AEC-7722 - SATA to SCSI - Low price & Supports SCSI Fast 20 (?) but intended for ATAPI devices. Needs a firmware hack to work on standard drives ?
• AEC-7732 - SATA to SCSI - Price > $150, Supports SCSI Fast 20

Less Available:

• SCSI2SD - SD to SCSI - Stopped making product in 2022. V6 has fast 10 support
• CF2SCSI - CF to SCSI - Not for sale via retail channels - Supports SCSI Fast 20 - Enterprise management features
• Mountain Secure Systems - SATA to SCSI - Not for sale via retail channels - Supports SCSI Fast 20
• AztecMonster - SD to SCSI - High price, limited availably
• AztecMonster II - SATA to SCSI - Discontinued

I think I'll try ZuluSCSI and AEC-7722

I reached out the the CF2SCSI group to find out their pricing. They work a niche of high durability & military applications. Their least expensive model starts at $1300. Their high end devices are over $20000.

CF storage for high durability applications? 😮 maybe they combine it with those small ridiculously expensive SLC cards.

I ended up using a 140gb 80 pin in this in hindsight I think this was a very good plan. Ease and performance are great. I even managed to exceed 8gb limit using windows 95 and pq magic

I also have a bluescsi v2 but haven’t gotten it working well in the application I have for it yet.
386—>486 build

BlueSCSI Ultra - Wide 68 Pin is now an option. The Ultra Wide negotiates to 40 MB/s but you have to overclock with bluescsi.ini to 20 MT/s (Wide is 16 bits so that equals 40 MB/s)
See https://github.com/BlueSCSI/BlueSCSI-v2/wiki/ … ast20-OverClock
The Ultra Narrow negotiates to 16 MB/s.

I got both, Ultra Narrow and Ultra Wide, and so far I am pleased with them. Especially because it has CD-ROM audio with the addon board, and you can switch CD from command line using SCSITB.EXE.
But the perhaps most notable feature is, images on exFAT, which are ideal to work with in Linux using commands like "losetup" & "partx".
All CUE/BIN goes into a single "CD3" folder on the exFAT which is a far better solution than adding CD images to a huge DOS drive.

The SCSI controllers I use are:
Adaptec ASC-29160 64-bit PCI card
Adaptec ASC-39160 64-bit PCI card
Adaptec AHA-2940U2W 32-bit PCI card

These install a drive into BIOS, have INT13 support, and CD-ROM support in DOS with a driver.
v4.0a SP3 drivers from https://theretroweb.com/uploads/drivers/fms-o … d9509404853.zip
CD-ROM support with SHSUCDX.COM from https://github.com/adoxa/shsucd
NOTE: Setting up CD-ROM in DOS with MSCDEX.EXE has compatibility issues when using BlueSCSI

Tested on SE440BX Pentium II & ABIT AB-SM5 Pentium MMX where the BIOS is updated for direct boot to SCSI drive.
Make sure to check https://bluescsi.com/docs/Compatibility for controller card compatibility and tips. You can also edit the page and add missing information.
