I have the vague project of >making a daisy-chainable virtual HD, and this would help me get >started. I took notes of the source code at >http://mirrors.apple2.org.za/Apple%20II%20Documentation%20Project/Peripherals/Disk%20Drives/Peltier%20SmartPortVHD/ROM%20Images/, >matching those with wiring info would be nice to make sure. Update: Steven sent me the documentation he had, this is now publicly available at https://github.com/colinleroy/SPVHD/tree/main/doc and should soon be mirrored at https://mirrors.apple2.org.za/Apple%20II%20Documentation%20Project/Peripherals/Disk%20Drives/Peltier%20SmartPortVHD/ It contains great resources for people wanting to understand the Smartport protocol. -- Colin https://www.colino.net/
