PowerBook BlueSCSI Version 4 [F1.TbA.PB.V4] Designed by: Tech by Androda, LLC
Big Changes: All surface-mount components No jumpers! The dual diode means logic or motor power will power the device with no selection necessary. Termination enable jumper is removed as well, because PowerBooks need termination 'always-on' Back to discrete resistors plus voltage regulator. The termination ICs used on the previous V3 design were very hard to reliably get working first try, likely due to invisible corrosion from sitting in a warehouse for decades. I could get them to work with some individual pin…
