Oh poor kid, what did they do to you?
This drive will donate its mechanism to the MegaloDOS drive I still have, which seems to have a mechanical issue on its Newtronics drive mech. I think these are the last two modded drives I will ever work on. I really don’t get these mods. MAYBE a device selector. But you usually don’t need to switch around drive numbers that often.

The drive mechanism itself looks to be in good condition. Motor driver board looks ok, as do the belt and the stepper motor.

The drive mechanism has another mod. The spindle motor power cables have been cut and some extra wires spliced in. The tacho is still wired up the same. I was told this was meant to spin the disks THE WRONG WAY if a switch was toggled, to make all the „backups“ work only on THIS drive (or other modded drives). However it seems this is not wired up anymore. I wonder if I should remove the splice.

The read head looks to be in good shape. Nothing wrong here. Luckily the ALPS heads seem to last longer than the unlucky Newtronics.

The stepper transport for the read head is very similar on both the Mitsumi/Newtronics and the ALPS drive. The stepper turns a small wheel that has a metal band attached to it, which is connected to the read head assembly, pulling it along two stainless steel rods, like a sled.

The power supply consists of this chunky transformer, which also looks spotless. On the main PCB are the matching full bridge rectifiers and filter capacitors.

The mainboard of this drive is pretty standard, and rather clean. A bunch of wires are attached to the jumpers for device ID selection. Those are easy to remove if this is desired. The 6502 has an additional B label, so it can probably be clocked higher.

@root42 Perhaps someone was inspired by the notebooks of Leonardo da Vinci?
