ESP32 port

[alexpeissel]

As the Arduino core is also available in the ESP32, would it be possible to do a port?

I believe the ESP32 is faster than the STM32F103C, (though I can’t speak to port manipulation). It is also dual core and loaded with WiFi and Bluetooth. One core could handle the SCSI emulation, while the other serves up a web interface, allowing drag/drop file uploads and downloads to the disk.

Ethernet over SCSI possibilities would also be amazing; a wireless networked SE/30 is the stuff of dreams :).

Ha! that would be neat. RaSCSI does have daynaport emulation working in the develop branch if you're interested. For now I wont be focusing on this but if someone was able to get it to work I'd happily buy an ESP32 to test and merge it in!

Might have to add level converters though. ESP32 is NOT 5v tolerant and I have burned out pins for that proof. However I have run SD card speed tests and can easily get 8 megabytes a second off the interface so it might be worth the try.

I'm a software developer with quite a bit of experience with the ESP32 (and Macintosh programming back in days) and maybe I will experiment with this. I was very torn about buying a BlueSCSI kit vs. a RaSCSI kit, because both projects seemed amazing! However, in the end, I ordered a RaSCSI kit because of the web support. Interestingly, the RaSCSI has level shifters and a big ol' header for the 3.3v Rasp Pi. Maybe with some strategically placed jumper wires I can wire it up to an ESP32 and try porting the BlueSCSI code to it.

Although I have to ask, is there any risk of blowing out a vintage Macintosh if the software is implemented incorrectly? I would hate to try this and fry my Mac Plus...

Not really. Honestly the NCR 5380 is fairly robust and can sink quite a bit of power. I have both built the BlueSCSI and have one of the older SCSI2SD adaptors. I would go toward the the RaSCSI as well just for the better interface as well.
