Wang2200.org

This page contains virtual media for the Wang 2200, which presently is mostly disk images, although in the future tape images may appear. These files can be used with the emulator, but it is also possible with enough effort to use the file to create real disk images to get running again that old Wang computer you found at the curb.

Just about all of the disk images here were contributed. If you have any old Wang 2200 disks in a box in the back of your closet, please consider contributing it to help grow this library. I have an 8" floppy connected to my PC and special hardware and software so I can read these old disks. In particular, I use a Catweasel disk controller and some custom software to decode these disks. Note that if you want to do this yourself, you will need a Catweasel card, and a PC which can run DOS, Windows 95, or Windows 98. Source code is provided, so it might not be too hard to recompile this to run on a Linux machine. In theory it should work with a Catweasel Mk 4, but I have only tried it with the Mk 3 design. The zip file also contains some notes on how I built an adapter cable to allow connecting the 50 pin 8" drive to the 34-pin connector on the catweasel card.

The "notes" links below mostly just contain the metadata of the disk and the catalog listing. These were generated by a utility program, available below. "wvdutil" is written in Python. Python is a pretty nice language, and this is my first Python program. Don't expect much.

Version 1.14 of wvdutil can list the disk catalog, set and clear the disk write protect status, set and clear program protect mode, list program and structured data files, check the disk and files for consistency, and change the catalog index style from the old 2 byte format to the new 2 byte format. See the readme in the zip for more detailed information. The zip file also contains a windows executable which can be used if you don't have python installed on your computer. This executable contains an embedded python interpreter and the necessary libraries. If you do have python installed on your machine, it is advisable to use the python version instead of the .exe, as the .exe is slower to start than the script version.

Finally, I have captured hundreds and hundreds of disk images, but not all of them are presented here. Capturing them is one part technical problem, one part perseverance. But that is the easy part. The harder part is going through them all, labeling them, getting rid of defective images and maybe extracting the valid files, resolving which of N variations of a disk image (eg, the TBO disks) should be presented. Then updating the website with all information. If anybody actually desires to see ALL the disk images I've captured and wants to do their own spelunking, let me know and I'll create a zip file for you. Currently it would be about 720 MB.
