Help with RT-11 V02B

Jerome Fine replies: The use of a monitor file with the integrated "monitor/device driver" was last used with V03B, as far as I can understand and see with the 7 RT-11 binary distributions that I have prior to V05.00 of RT-11. With V04.00 of RT-11, the separation had occurred. For V03B of RT-11, there was an "almost" impossible number of Monitor files to be distributed. Jerome Fine replies: For V02B of RT-11, as far as I can see, the hardware boot code is only in 2 blocks of the device - block 0 and block 2. By V04.00, the hardware boot code had also expanded to blocks 3, 4 and 5. As for the boot code being in the first directory segment, V04.00 contained a DY.MAC file with code for a double sided RX02 drive. However, I don't think that the hardware boot code allowed the monitor boot file to be on the second side of an RX03 floppy. At one point, I ported the code from V04.00 of DY.MAC to V05.03 of DY.MAC for RX03 media. However, I don't think I bothered to correct that aspect of the boot code. At this point, I am confident I can finish a CD with about thirteen RT-11 distributions of RT-11 for V05.03 and prior. For V05.00 and later, there will be RL02 file images that are bootable. Prior to V05.00, there will be RK05 file images that can be booted. After that is done, my goal is to work on a Y10K compliant V05.03 of RT-11 for hobby users.
