I've put the DOS/VS r34 install tape on my site. It'll expand to a 21 MB AWSTAPE file, dosrel34.aws. You need the Coverletter to install it. Read the relevant postings of the Hercules mailing list first, as the install process is quite obscure.
You also need enough hard disk space to accommodate the emulated DASD. A virtual "3330 model 1" disk drive will need about 100 megabytes of space for emulation (a 3330-11 will need about 200 megabytes). A 3380 "single density" model will need about 650MB, a 3390 model 2 needs about 2GB, and a 3390 model 3 needs about 3GB. If you use thecompressed CKD DASD feature, these sizes will shrink dramatically, usually to about 20 to 30 percent of the original size.
