Subject: Settings for Mitsumi/Tandy CD-ROM?

I was given an old Tandy CD-ROM drive.  The controller for this drive
has Mitsumi printed on it in small letters on a part on the card.  So,
I decided to see if it would work with the Mitsumi CD-ROM driver in
NetBSD-current.  To my utter amazement, it read an Ultrix
documentation CD with no problems.

However, when autoconfig probes it on bootup, I get this:

	mcd0: timeout in getreply
	mcd0 at isa0 port 0x300-0x303 irq 3

Then, if I try to run workman on it to play an audio CD, I get kernel
messages like this:

	Apr 30 00:11:59 MindBender /netbsd: mcd0: timeout in getstat
	Apr 30 00:11:59 MindBender /netbsd: mcd0: timeout in getreply
	Apr 30 00:11:59 MindBender /netbsd: mcd0: timeout in getstat
	Apr 30 00:12:00 MindBender /netbsd: mcd0: timeout in getreply
	Apr 30 00:12:00 MindBender /netbsd: mcd0: timeout in getstat
	Apr 30 00:12:00 MindBender /netbsd: mcd0: setting mode to 5
	Apr 30 00:12:00 MindBender /netbsd: mcd0: setting mode to 5
	Apr 30 00:12:00 MindBender /netbsd: mcd0: setting mode to 1

And, no matter what, workman thinks the drive is empty.

Like I said, even though I get these problems under specified
conditions, it reads an Ultrix CD-ROM without a single problem.

I have two questions: 1) Does anyone familiar with the mcd driver know
of anything special I'm going to have to do to get workman running?  2)
Since this drive was given to me, I have no documentation -- can
anyone email me the switch and jumper settings for their Tandy and/or
Mitsumi CD-ROM drive?  If it makes any difference, mine's just an
8-bit controller board.

Thanks for any clues you can send my way.
