Jethro,
A quick check show this is a very common problem. Lots of posts on BBs like yours, show up on a Google search.

I went to the TASCAM web portal and found this page.
http://www.tascam.com/Support.html
Read through it and use the links. I think you should be able to get an online PDF manual there.

Kurt,

Thanks for the tips, but I had already exhausted that route before posting here. The tascam site has nothing about the older models and my google searches were fairly fruitless as well. The best lead I got from google was this site.

I've tried using the MKIII manual but the machine I have looks a lot different. The input selectors, the switches near the vu-meters, bus/trk switch are all different.

Any other ideas?

thanks again,
Jethro

I think you best bet is TASCAM. Contact a service specialist there and ask if you can get a copy of the manual. You might have to pay a few bucks for it but I would almost bet the ranch that they have them on file somewhere.
