I’ve finished assembling the first prototype board of Yellowstone 2.0, my FPGA-based universal disk controller for Apple II computers. I used a syringe to dispense solder paste onto the pads, and baked the board on a hot plate with the…
Today Big Mess o’ Wires is releasing two new products for use with the BMOW Floppy Emu disk emulator for Apple computers. Remember the dual 5.25 inch floppy emulation mode that was announced back in February? It gave the Floppy…
I’m seeking help from all the Apple II programming gurus, with what may be an obvious question. During the development of the Yellowstone FPGA-based disk controller, I’ve written several times about my goal of providing a way for users to…
The Wombat ADB-USB input converter is now back in stock at the BMOW Store. Thanks for everybody’s patience while we waited out multiple delays on delivery from my manufacturing partner. There’s now plenty of Wombat stock at BMOW HQ, so…
Good news: the International Shipping Fiasco of May 2021 appears to be resolved, although the underlying causes are still unclear. Early indications are it was some kind of USPS screw-up with electronic collection of customs data at the San Francisco…
The Yellowstone version 2.0 PCBs are here! They sure look shiny. I wonder if they work. This is the second generation of my FPGA-based disk controller design for the Apple II. In comparison to the version 1.0 PCB, you can…
Update: It looks like this problem may have been resolved by USPS, with international shipments sent May 11 or later proceeding normally. But there’s still confusion about the source of the problem, the date it was resolved, and whether it’s…
The Yellowstone 2.0 disk controller PCB has been sent to the fab. Now we wait. It took longer than I planned to finish it, first because I wasted a couple of days trying to shrink the board by 7 mm,…
It took longer than expected, but the PCB layout is finished for version 2.0 of the Yellowstone disk controller. Phew! There’s still a bit of cleanup work to be done before I send the board for manufacturing. Hopefully I can…
