I was considering this tonight. I'll probably make a separate box with
just SCSI devices, so I can easily mount those and then install a 10base2
network between the two boxes so I can easily access those drives from the
box with the tape drives. SInce my whole setup will most likely be
DOS-based, I can use a simple P2P LAN such as LANtastic (LANtastic was
very cool for what it was in its day).

Yes, well the 10 megger I mentioned may well be a 44 megger. I didn't pay
closer attention to it.

I'll definitely want all the various types if the larger ones are not
backward compatible. From what I understand, Bernoulli 230 drives can
not read Bernoulli 150 drives. Somebody please correct me if I'm wrong.
I don't yet have a controller for any of these drives, so am in need.

The drive I am getting is a dual drive, so maybe it is a 10 megger after
all.

Of course. I used this sort of tape drive extensively with the Colorado.
But you'll never be going from tape to floppy or vice versa. And if you
had to, you'd of course dump to the HD first and then out to floppy.

I need those 6-8 drives then ;)

Well, I got to if it's to be worth while. The idea is to create one ready
to use super box that can convert from just about anything to just about
anything else without requiring a long search for the right drives,
software, and hardware for the media in question. The emphasis is on
just reading the data which will eventually go to CD-R. So it's important
to be able to read just about anything, but writing isn't as critical.
Usually when someone wants data converted these days, they want it on CD
or 3.5" floppy.
