I figured you would give the answer Greg. I loved working on the machines with core memory. The drivers were getting a little hard to find at the time. We bought up al the TI 75???s we could find at the time so we wouldn't run out. I still remember having to fix a Data General 1200 or 1220 CPU with core memory. It couldn't load the diagnostics from mag tape. I pot in a good CPU, loaded from mag tape and shut down. Then I swapped in the bad CPU and powered up. The diagnostics were still in core. The Mini-Megs couldn't have pulled that one off.
On the original question, does IPL bootstrap or BZUP ring a bell with anyone?
