EME-157 drive mod

[caver99]

i got a pcw 8256(512k) off of ebay and it has the white plus floppy drive in it, which didnt work.
gave the drive a service and now its fully working in the pcw.

im looking at doing the abba mod on the pcw the retro nerd did on there's, but the drive they used was the EME-156(standard drive)

would anyone beable to assist in the drive a/b connections shown on the pic of the 156 and i have added a pic of the 157

i do have a 156 but it had a broken head stepper motor so is dead.
