Correct. As mentioned on the Updating Firmware page of the Wiki, the ".uf2" files are the firmware. You can tell that it's installed onto your Pico by applying power without an SD card present. The Pico's LED will flash 5 times, pause (with LED off), and then loop again with the 5 flashes...

Allow me to explain. The RP2040 microcontroller used on these Pico boards has one design decision that strikes me as fairly dumb with how modern systems work. When the chip initializes and starts up, every GPIO pin is set up in "pull down" mode. This means every pin tries to pull the signal...

The super cool thing about this release is that it works across all existing BlueSCSI V2 Hardware. We don't have separate builds for WiFi, or separate builds for Initiator hardware. One binary for all, no confusion, no mess. And speaking of Initiator hardware, that's merged into the BlueSCSI V2...

My initial reaction is that RAM Doubler would be faster overall. Compression uses CPU cycles, yes, but those CPU cycles are likely still dramatically faster than reaching all the way out to a hard drive. Even if that hard drive is an SSD.

There's one adapter board left as a kit, if you feel like assembling it. I have more of these on the way from the PCB manufacturer, and will then have some assembled available.

As an overall note, those pictures are very blurry. It's hard to see details in them. Just to restate, you have tried a BlueSCSI V2, a DB25 BlueSCSI (which version? V1 or V2?), and a Zulu and none of them work? There could be several things going on: * this might be trying to use custom...

I've been thinking about something that could work with the video out port on the Portable. I keep trying to move on to things other than the Portable but it keeps pulling me back (yet another Portable project is underway now at the schematic stage). The VideoMacPack is particularly weird, the...

Been working on an update to the BlueSCSI Desktop board for awhile, and it's not quite done yet. But figured I'd clue you all in: Initiator Mode This allows BlueSCSI V2 to in-place take byte-level images of original SCSI drives without needing the actual host machine. It could also lead to...

Contest submissions are closed (closed a few days ago actually). The judges are deliberating now.

Please note that there were no board meetings in June or July due to a lot of scheduling conflicts. August 26, 2023 Board Meeting Attendance: Kai Robinson, Christian (fogWraith), Jacob (Androda), Eric (eric), Ron (Ron’s Computer Videos), Justin (jdmcs) Absent: Bruce (Branchus), Josh (Drake)...

Looks like that picture of old and new DB25 side by side has the prototype version of the smaller DB25, oops. The version I pushed to GitHub (and which the sellers will have) includes an activity LED by the microSD slot.

Adapters do exist for using a BlueSCSI with the Portable, on my site. These ones *only* work with BlueSCSI though, and do not present a Molex connector for use with a different drive style.

Yeah, that's the paradox you as the buyer will find yourself in. As a "best practice" I would say you should send the seller a request for lots of pictures. If they are unwilling to open the battery bay, remove any batteries which are present, and take photographs of it from various angles...

1: The Backlit Portable has a similar circuit to the "hybrid", just directly on the motherboard instead of on a dedicated separate PCB. It's very vulnerable to capacitor leakage, as the keyboard/trackball connector next to it has a few capacitors right there. @techknight would know failure...

This is basically what I expected. The RP2040 microcontroller designers made the rather strange design decision to put all IO pins into "pull down" mode at chip startup. This means that the control line (not data) transceivers pull lines low until execution enters our userland code out of the...

That's pretty cool, free CPU accelerator from simply running the expansion RAM faster. Maybe I can stick that into the CPLD somehow, another pin for great acceleration...

In order to assist the BlueSCSI sellers in testing their devices, I created this semi-monstrosity known as either the SCSItron or BlinkyTester or something along those lines. It's the SCSI-est thing I've ever made. It consists of a standard 50 pin SCSI input connector, and presents a bunch of...
