I had the chance to talk with the fellows out at the CHM that restored the
1401. They had trouble with stock as well, especially with their high speed

uses IBM's dies and stock that has the correct surface friction. Check out

Like roll paper for the TTY's, if you watch ebay you'll find a few deals on
new old stock cards. Plusboxes can be shipped as media mail. -C
