BlueSCSI Wi-Fi Desk Accessory
The open-source, open-hardware SCSI emulator BlueSCSI v2 can emulate a SCSI Ethernet device using the Wi-Fi chip on its Raspberry Pi Pico W microcontroller, with firmware functionality I wrote in mid-2023. While this becomes largely set-it-and-forget-it on desktops, portable Macintoshes can benefit from the ability to see Wi-Fi signal strength and join other networks without having to edit the BlueSCSI configuration file.
Shameless plug: If you have a PowerBook 1XX that needs a new battery, I make new ones.
In addition to the basic network packet bridging code that I added to BlueSCSI's firmware, I also added a set of vendor SCSI commands that enable scanning for nearby networks, joining a new network, and viewing current network information. For Macs running System 6 and later (tested with System 6 and 7), I've created a Desk Accessory that uses this functionality.
Latest Update: BlueSCSI Wi-Fi Desk Accessory 1.0 Released (2023-10-25)
BlueSCSI Wi-Fi Desk Accessory 1.0 has been released:
(StuffIt 3 archive)
2d10cef73b81119a 1fec3848e4d1d88f f652a07ffdc6a69a
This is the initial public release of my BlueSCSI Wi-Fi Desk Accessory for classic MacOS.
Source code and its THINK C project file are contained in the latest release archive, or it can be viewed on AmendHub.
On System 7 and above, drag the Wi-Fi suitcase onto the System Folder and click OK when asked to put it into the Apple Menu Items folder.
On System 6, launch the included Font/DA Mover utility. Click the Desk Accessory radio button at the top, then click Open… and locate and select the Wi-Fi DA suitcase. Select Wi-Fi from the list on the right side, then click « Copy « and Quit. A restart may be required.
After installation, a Wi-Fi item will appear in the Apple menu's list of Desk Accessories.
Once launched, the Wi-Fi DA will scan the SCSI bus to find a compatible DaynaPORT SCSI/Link device and then check to make sure it's actually a BlueSCSI emulated device.
The DA will then query the device for the current Wi-Fi network name and RSSI, and launch a background scan of nearby networks. Clicking on the network name will pop-up a list of networks which is populated once the background scan completes (usually within a couple seconds). If the selected network uses encryption and requires a password, the DA will prompt you for it.
After again asking the BlueSCSI device for its status, if it is now connected, the DA will update with the network name and RSSI:
As the Wi-Fi DA is left running, it will periodically poll the BlueSCSI device for its current network name and RSSI and update the window accordingly. At larger intervals, it will do a periodic background scan to keep its list of nearby networks up to date.
