The Teac drive I'm trying to get working is a teac

to get a shugart 455 AA5 and 455 3AA working with a California Computer
systems shugart incapable FDC. The CP/M computer with format but fails
to read or write to the floppy afterward. My goal is to get a floppy
exchange between my PC and CP/M machine. I'm formatting Single side
Double Denisty and 512k sectors. I'm using 22disk on the dos side and do
have a somewhat working solultion with a shugart 400 and a old 3 /1/2
and 5 /14 combo drive. I do now have the settings in 22 disk correct as
it reads and write sometimes with errors between the two machines. I get
sector not found errors when it does fail. Thanks
Well, the FD-55BR identifies a "360K" drive, but not much past that--
you should also have at least three numbers and then some letters
after that.
I'm guessing that your CCS probably requires you to strap the unit
select to D0 for the first drive vice the PC "twisted cable" D1. I
also suspect that the CCS needs DRIVE READY/ on pint 34 (another
jumper). Since we don't know the rest of your drive model, we don't
know if you have a head-load solenoid, or any of the other special
features that Teac could pack a drive with.
Here's a start for you:
