On the KA/KI you could read in from the RC10 and RH10 controllers. The RP10 did not support read in. Also the PTR and TMA/TMB controllers supported read in. > The reason I ask is that ITS DSKDMP seems to include code for a disk > boot block, but it's a bit of mystery how it was used, if at all.

For my KA/KI simulator I have added support for read-in off the RP10 controllers, by simulating a read of blocks 4-7 and dropping them into memory where they should be.
