Hmmmm.
You need to either have a boot disk in the drive (you said that you didn't
have one), or press the break key when booting to get video.
If that isn't working, the video might actually be bad, or the break key
may be non-functional. If it is the brass contact type, pull the keytop
and clean it. Or press it a few hundred times. If that works, you may
need to exercise the rest of the keys. See if Frank has my old centronics
KGS80. Put it on the keyboard and dump this list through it.
