	Well... someone (havn't got the name right in front of me)
send me rather complete doumentation on the 7053 card... and I have
the jumpers set correctly.  Now... I also have a 3/260 and several
spare SMD cards including a 451 and another 7053.  I only have 7053
cables, however.

	But... this will allow me to test this stuff out on my Sun
3/260 as well.  Now... it's very possible that the new 150M cartridge
tape drive in my 4/260 won't boot sun tapes, but I'm assuming that my
Sun3 will... and that I'll be able to run format/diagnostics on the
drives from the SunOS install.

	I'm hoping to have some time tomorrow to try this.
