John,
Summary of results, running simH on a $9.95 Next Thing Co CHIP.
1. I built an RL01 disk with RSX11/M that boots within simH using the
files I found online.
set cpu 11/40
set cpu 64K
set rl0 writeenabled
set rl0 rl01
set rl1 writeenabled
set rl1 rl01
set rl2 writeenabled
set rl2 rl01
set rl3 writeenabled
set rl3 rl01
attach rl0 rsxm32.rl01
attach rl1 excprv.rl01
attach rl2 mcrsrc.rl01
attach rl3 rlutil.rl01
boot r1
1.5. Within RSX11/M make it boot into the mapped version each time -
> 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!
Bill
