Introducing ZuluSCSI Pico Slim (with Wi-Fi Daynaport emulation)

[rabbitholecomputing]

Rabbit Hole Computing is proud to announce ZuluSCSI Pico Slim, the smallest SCSI emulator in the world* (that we know of). Inspired by @zigzagjoe's original SillyTinySCSI, we wanted something that would have fewer clearance issues on the largest variety of Macs. The ZuluSCSI Pico Slim enclosure and PCB designs are commissioned works by @zigzagjoe. At just under 12.5mm/one half-inch in thickness, the ZuluSCSI Pico Slim lives up to its name. Full dimensions, including the DB25 connector and enclosure, are 43mm L x 61.25mm W x 12.5mm H.

ZuluSCSI Pico Slim is equipped with a high-quality Molex-manufactured push-push microSD card socket. The Amphenol-manufactured DB25 connector is sturdy, as is our included 3D-printed clamshell enclosure. compact, and is held together with four M2x8 screws. With ZuluSCSI Pico Slim, the focus is on durability and quality.

We're selling our fully assembled, tested, and enclosed ZuluSCSI Pico Slim units for $59 each. We're also using this product release to begin our transition to a much more user-friendly, easier-to-use web shop.

At the moment, we've chosen to only sell fully assembled (including enclosure) and tested ZuluSCSI Pico Slims. Another US-based partner is also selling assembled and tested ZuluSCSI Pico Slim boards without enclosures, available today on eBay.

There are un-branded step files for the enclosure at on Thingiverse, which anyone is welcome to print on their own, as well as make derivative designs. The enclosure design is licensed under the Creative Commons - Attribution - Non-Commercial license.

It's fantastic to see this finally released! I'm proud to have been part of the process to bring this to fruition

Just grabbed one. Excited to check it out.

This is great, thanks you! I've never gotten the SIllyTiny's WiFi to work properly...maybe this will work.

Neat, production SlimSCSI. I'm tempted to swap my Q700 from an internal unit for easier disk changes.

Seems like it'd block just a small bit of the fan opening with a right-angle adapter?

Nice! Next time I need another ZuluSCSI, this will be it!

I wish there was a way to buy these in the UK for a fair price. Amiga Kit is expensive…

Well, @rabbitholecomputing kindly helped me out with a ZuluSCSI Slim in the UK. I just wanted to say how pleased I am with it, it’s beautifully engineered and a quality piece of kit. I am using it on my testbed SE/30:

I purchased the ZuluSCSI Slim Kit - any recommendations brand/model/gauge bodge wire to use to connect the pads on the ZuluSCSI Slim board to the USB pads on the Pico W?

Branchus Creations covers this in his build video here at 4:42 timestamp (link should go right to it):

I bought the "34 AWG enameled magnet wire" from the affiliate link in the video description, but I cannot remove the enamel with my soldering iron.

It says rated at 155C but even at 300C my iron won't take it off. Tried difference sizes of conical and wedge shaped tips. Any ideas of a better product or what I might be doing wrong? Thanks!

It can be absolutely anything. On my original prototypes I used a single strand out of some random wire (I think it was CAT5? )

I wanted some nice bodge wire for other projects anyways. I'm sure I could macgyver something, but part of the fun of building is accumulating appropriate tools and such Thats a good idea about the Cat5 however. I just liked how easy Branchus Creations made it look in the video

I use 30ga tinned wire-wrap wire. A small roll has lasted me 40 years so far, and there’s plenty left yet. I’ve seen some YouTube videos where the bodge wire is a strand taken from 18ga stranded wire, but the pre-tinned wire is so easy to use.

As far as the enameled wire goes: The enamel can be scraped off, if it is refusing to respond to a soldering iron.

I got the enamel to melt when I set iron to 400C - I use 63/37 solder and don't normally ever set the iron that high. The production listing for the wire says 155 C!

ZuluSCSI Slim firmware installed via the USB port on the ZuluSCSI Slim board - so I guess it works. Didn't need to use the port on the Pi. I see ZuluSCSI firmware output via serial terminal!

DaynaPort Emulation and scuzEMU work as well. Cool device!
