1541 SAMS Computer Facts CD4 Technical Service Data

This original SAMS computer facts folio is in really good shape. My copy of this is my go to service manual when working on a 1541. Condition - Has been opened and used but in great shape. The cover is marked "AV Dept." and there is some tape on the cover as well. Where the original seal was broken there is about a 1/4 inch tear. (See images) The actual service documentation in the folio looks like it was never used. There are couple smudges but it is in great shape overall. This does have the usual musty smell, as is typical from Stone Collection items.
