ok, thanks I was referring to the MacSD web site, which says: "... A single image file may not exceed 4GB due to FAT32 limitations." It sounds like if image files aren't being used, then MacSD can support volumes of any size that can be defined as a partition in the MBR partition table, is...

No, I'm not in imarketing. ZuluSCSI v6.4 (the one I would get that is comparable to BlueSCSI v2) is only $120, but that's still a bit more than $50. https://store.rabbitholecomputing.com/ZuluSCSI-V6-4-p/zuluscsi-v6.4-rev2024a.htm I would enjoy seeing helpful comments and other benchmarks...

I didn't do those. ZuluSCSI is too expenive ($150 USD compared to $50 for BlueSCSI). And, as I understand it, MacSD uses FAT32 filesystems instead of ExFAT, so it only supports file sizes (raw partitions) up to 4 GiB, which is big enough for Mac OS, but not big enough if you also want GNU/Linux...

Hello, Below is a MacBench 4.0 omparison of the SCSI2SD v5.0b and BlueSCSI v2 on a Centris 650 with 136 MiB memory, running Mac OS 8.1. (The screenshots were reformatted by Finn Thain for better readability.) Methodology: 1) Write zeros to all sectors of a 16 GB SanDisk Industrial microSD...

thanks for your reply; the capacitor lists are good, but of course schematics would also be helpful for troubleshooting and might allow completely rebuilding the PSU from scratch with more modern components.

Hello, I would like to re-cap the PSUs in a few IIci systems and a Quadra. Is anyone aware of where the schematics for the following PSUs can be purchased or downloaded? If the schematics are not available, does anyone know who might own the copyrights now or perhaps reverse-engineered the PSUs...
