Short video of the RK8 disk test read/write running on my old pdp-8i

I no longer have this system, but it was fun to work on and get parts working. It had a bit 6 problem on the external bus which
causes the write portion to fail. Never did find the cause. But I always enjoyed watching blinking lights so I hope some others
enjoy it too. https://www.youtube.com/watch?v=mwrEPASoCOA

Seeks are really noisy. What model disk?

I believe they were RK02's or something similar. THey held half as much data as an RK05.

wow, those are IOMEC drives
RK01? They were 100tpi, same as IBM 2315's

That appears to be correct. Wasn't sure.
