I already had a couple of V5 SCSI2SD boards and they worked well enough but I prefer full sized SD cards so I thought I’d try a V6. I hooked up the V6 to a Ramfast SCSI card and tried a couple of SD cards and it was like the board was dead. Then I pulled a known working microSD card from a V5 and tried it with an adapter and that worked. Tried a few more SD cards and was getting nowhere. Got this idea that maybe the microSD card worked because it was preformatted and partitioned with ProDOS so I used an acard SCSI to ide card with SD adapter to format a few SD cards. They still didn’t work with the V6 board.
So I thought I’d try changing the configuration of the SCSI2SD board but it didn’t seem to be saving the configuration. Then I tried it with the working microSD card and realized that it would show up on the Macs desktop. Now I knew what was happening. So I tried my SD cards and none of the SD cards under 1gb would work with the V6 board. A few 1gb would, strangely some of the same brand, outwardly identical would work and some wouldn’t. All of the 2gb worked. All of the microSD cards I tried would work but I don’t have a lot of those.

Good to know. I have a RAMFAST in my iigs and was going to purchase a SCSI2SD but version 5 as i have heard it has better compatibility. How did you hook up the unit itself - internally with a modified ribbon cable or externally with some type of 25 pin scsi connector to ribbon adapter?

I've been using a SCSI2SD v5.0a with a RamFAST D on my IIGS for a couple years and haven't had any problems with it. I have the SCSI2SD mounted in an external SCSI1 HD case.
For the SD card, I use a 2GB industrial pSLC card partitioned as:
1) 10x ProDOS partitions, each 32MB
2) 1x HFS partition of 1736MB
Below is the MacOS X partition command I used to create the 11x partitions:
sudo diskutil partitiondisk /dev/rdisk1 13 APM %Apple_PRODOS% PART1 65536S %Apple_PRODOS% PART2 65536S %Apple_PRODOS% PART3 65536S %Apple_PRODOS% PART4 65536S %Apple_PRODOS% PART5 65536S %Apple_PRODOS% PART6 65536S %Apple_PRODOS% PART7 65536S %Apple_PRODOS% PART8 65536S %Apple_PRODOS% PART9 65536S %Apple_PRODOS% PART10 65536S %Apple_PRODOS% PART11 65536S MS-DOS HFS1 3473000S "Free Space" FREE R
Then in RAMFast.system, expand last partition to max (2GB), then format as HFS in Adv Disk Util or Finder

On my card - the internal ribbon cable from the card to the connector on the rear will need some type of breakout to the 50 pin on the card. How did you do that exactly?

In this case I just used an internal 50 pin to centronics adapter. Just a temporary arrangement for testing.
I do have a towerized IIe where I made a custom cable that connected the SCSI card to a hard drive and CD drive. It also went to a female DB25 on the back of the case. Normally I have a terminator plugged in there but I could connect external drives to it. Something like that would work well in a IIgs. I had a similar arrangement once when I slung a hard drive under the keyboard of a IIe.

I don't have the fuzinmonster, I have a raizinmonster. However I really like it. I installed it in a case where the faceplate fits the opening. Connected the SCSI ID jumpers to cases selector switch in case I ever need a different ID. Zero problems. Seems comparable in speed to the SCSI2SD.
