"Whimper" newsletter

[Richard A. Cini]

Well, I can say that it works fine. I connected the ST225 (20mb) to the
external connector on the T2K controller and did an HFORMAT and it worked.
Problem is that it formats only to 10mb. Someone told me there was a way to
force HFORMAT to format up to 20mb but it must be hidden commend line
switches.

What I might do is connect it to a PC and format it using a DOS 3.3 boot
disk, then reconnect it to the T2K and see what happens.
