If anyone has removed the write protection circuitry from either
a 8" or 5 1/4" Tandy hard drive I would appreciate a note of the
method used.  I am trying to dope it out myself, but any help
would be appreciated.

Does anyone have a WD SASI card available, such as is used in the
15MB external drive?  Can a XEBEC 1410 SASI card be substituted?

Thanks to gary@wibbs, I have a working copy of ucpm (CP/M SSSD to
Tandy XENIX).  If you want either a uuencoded binary or source,
send me mail.

I have a note giving instructions on upgrading 256k RAM cards to
1MB via the substitution of 41256 DRAMS for the 4164 devices.

Thanks.
