The ware for July 2019 was an Adtek aISA-P21, 16 input, 16 output isolated parallel I/O board. I really do admire how clean, crisp and orderly the board layout is on this one. It definitely bears several hallmarks of a Japanese design aesthetic, from the style of the SOICs to the font choice to the general organization and tidiness of the board assembly.
Congrats to Adam for nailing it, email me for your prize! I’d love to know more about how you knew what it was — had you encountered the board before? Or just a lot of sleuthing through the Internet. Either way, I didn’t expect anyone to get this one down to the exact make and model.
