BlueSCSI v2 Pico - Low cost, open hardware, fast SCSI device!

[Arbystpossum]

I've been having an issue as of late, with my own BlueSCSI. It's on a Quadra 605, card is formatted, known good, single .hda file. Any version of MAcOS 7 seems to corrupt itself when writing files to itself. MacOS 8.1 runs fine, writes/reads fine, but if I install MacOS 7.1-7.6, if I write more than ~20MB to the BlueSCSI from network/External SCSI, the system will freeze, eventually a system file will get caught up in the mess and it will boot to a [?] icon. Only under System 7 though. I'm not sure why.

I've had a BlueSCSI drive image corrupt itself in a Quadra 605, but it was overclocked at the time, which meant the SCSI chip was operating out of spec. IS your's on the stock clock speed?

Reminds me of the time when I was still using SanDisk SD Cards. I regularly lost my images with several of them. What make of SD Card are you using? Have you tried another one?

I've updated the BootStrap image to be a bit more user friendly for Wi-Fi setup. Instead of organizing by software I've organized by high level systems:

* MacOS 6 - MacTCP, DayanaPORT driver disk copy 4 image, MountImg
* MacOS 7 - MacTCP, DyanaPORT SMI image.
* MacOS 7 (5MB+ of RAM) - Open Transport installer, DaynaPORT SMI image.

I've also updated the BlueSCSI Wi-Fi DA to 1.3 and some other apps.

Well since the Raspberry Pi foundation thinks a bit of an overclock is OK we'll be (hopefully) merging this overclock into the next release. It will support SCSI FAST20 timing and users have reported up to 16.8MB/sec with a Pico2 and 15.6MB/sec with a Pico1

Give it a try if you have a compatible card that still has a narrow interface or you have an adapter. For Macs these only came as option or 3rd party cards. Also for Macs remember to use FWD toolkit drivers!

Absolutely amazing work! I’d love to see an option to create BlueSCSI PCBs with SCA2 connectors on them, so that they could easily replace workstation SCSI HDDs.

I am not, unfortunately, aware of a source for the connector.

There is an IDC male, but no SMD or THT male, as was included on SCA2 SCSI HDDs.
