I intend to add a 3.5" floppy and was wondering if I could use the 1.44 Mb version. I have been told that the 1.44 drive requires a 10 Mhz CPU which is why IBM doesn't put them in the Model 50. I'd appreciate hearing from anyone that has tried this - successfully or otherwise.

In all MicroChannel Architecture (MCA) PS/2s (models 50, 60, 80, & 9370) a 1.44MB disk is used. The 1.44MB disk is backwards-compatible with the 720Kb drive. Also, unless I'm mistaken, CPU and disk capacity are not related (corrections, please) except logically (by which I mean one does not match a multi-gigabyte disk with a 1 MHz, 4-bit CPU because of relative cost).

The model 50 does have the higher capacity drive. If you want to put the new drive in an AT you will need a new controller card. Try calling Manzana at 805-968-1387.
