Re: Who owns a 8050/8250 with tandon drives?

The push-down-to-close/push-down-to-open drives are Micropolis.

Unfortunately the Tandon and MPI drives both use the flip-up/flip down
latches and look almost identical, especially when closed.

If you look in the slot when it's closed you should see a ~4mm wide metal
bar on either side of the latch in the Tandons that is not visible in the
MPIs; they prevent latching if the disk is not fully inserted and help to
push it into place.

When you open the Tandon drive door and look inside, the plastic 'cone' that
locks the diskette hub looks like it is flush with the pivoting upper
bracket that it's mounted on, whereas on the MPI there's a gap about 6mm
wide between the cone and the bracket, and you can see the shaft and the
spring.

Clear as mud? HTH,

I could take/post pictures if absolutely necessary...
