I/O tester System 360

[TXBigDaddy]

Here is the first of many posts to come of the items I'm hoping to share with you guys. I'm hoping you guys could help me determine value and identification. Generally we do e-waste recycling but this new score is full of really cool mainframe and tape drives....complete and in original form! I would rather give the people on this forum first crack at buying these items.

This I/O tester appears to be from 1965. It has 8 templates/cards and instructions. Any additional insight as to what it is and if there is any collectible value here is much appreciated? I plan on selling everything I'm posting here in the appropriate section of the forum.
Thx

My father was an IBM sales rep and he sold the IBM 360 family of mainframes. Seems like he sold a couple of 360/40's to A&P
(a grocery store chain) out of New Jersey in the early 70's.

I sold the 370 family of IBM mainframes like the 370/148, 158
and all the peripherals that went with them like 3350 disk drives,
3420 tape drives, 3203 / 3287 printers, 3271 / 3272 / 3277 / 3278
terminals and controllers and so much more. God, I'm old!

These items are from an estate of a gentleman that worked for IBM and began collecting tape drives and mainframes. He also has a bunc of banking machines NCR. There are 2 10,000sqft buildings we're clearing out. I've never seen anything quite like this
