I have made the bootable RL01 image and it works in simH. I have
BB-L974F-BC_RSX11M_4.5_BRU64K.tap in place but what kind of tape device
do
I set in simH to attach it? I need to attach
prior to booting and the
within RSX11/M
If you?ve set the simH to an 11/40 you can attach it to tq0 before
booting. It will
boot a standalone system so the tape is no longer needed after the
boot. I was
unable to successfully boot the tape in less than 256KB so make
sure you have
sufficient memory enabled.
ins $boo
boo [1,54]rsx11m
2. I installed a blank RL02 disk (rlRSX11M.dsk is a blank RL02)
3. I downloaded the tape from bitsavers with the program that copies from
RL01 to RL02
BB-L974F-BC_RSX11M_4.5_BRU64K.tap
4. Created a simh script to load up the tape. I called it
RSX-11_copy2RL02.ini:
set cpu 11/40
set cpu 256K
set rl0 writeenabled
set rl0 rl01
set rl1 writeenabled
set rl1 rl02
attach rl0 rsxm32.rl01
attach rl1 rlRSX11M.dsk
attach TQ0 -r BB-L974F-BC_RSX11M_4.5_BRU64K.tap
b TQ0
This took me into the tape utlity. I set the date and then entered the
command
first device is dl0:
second device is dl1:
run bru
BRU> /init dl0: dl1:
5. I fired up PDPGUI and used the Tools --> Read/write disk images utility
to copy the RL02 disk to an actual RL02 disk on my PDP 11/40
I then checked and saw there is a wash running, my PDP 11/40 shares the
washing machine circuit so I have to wait until the wash completes, it
takes a number of hours to copy the disk via PDPGUI so I will probably do
this in the morning.
Fun!
