BLKLDR 1 is from the IMLAC; IML DEVICE archive file dated 1976-11-02.
The archive was found in three identical copies on ToTS tapes 7006990,
701351, and 90606; they were extracted by Brad Parker. The BLKLDR 1
timestamp inside the archive is 1975-01-26. Tape database records
from DM show a BLKLDR 4 dated 1974-08-19.
To build the IMLAC; IMLAC BLKLDR file, it's first assembled with
MIDAS. Regular IMTRAN writes the block loader format, but the block
loader itself is in the "special TTY" boostrap format. IMTRAN is
runtime patched to skip the block framing.
The file IMLAC; SSV 52 dated 1973-01-07 was edited to match the Imlac
block loader format file http://www.ubanproductions.com/Imlac/ssv,
which claims to be SSV 22. SSVMSE 38 from 1977-12-13 was also helpful
in the process.
IMSRC; SSVCHR 22 is entirely from disassembly. The original file
would have been machine generated by SYMFOR.
The PDP-6 must be attached. Type L and a file name to load it. Start
the PDP-6 from 0. Toggle switch 1 on. Set address switches to 0 to
play from the memory indicator lights.
Needed to assemble MUSRUN.
The patch to TSYMGT+5 is to make a larger memory area for receiving
data from .GETSYS. The type of data is CALLS, the list of system
symbols. Presumably one page was enough when MIDAS 77 was current,
but now eight pages may be needed.
disk parameters to separate file (system;rp04 >) from system;rh10 >.
Made build default to RP04 when RH10 is specified, but switches
can select RP06 for relevant components. Resolves#1648.
I'll reiterate the depencencies involved:
- STUFF wants the AI IOELEV in .
- 11STNK wants KLRUG in .
- 11BOOT wants IOELEV in the same directory as KLRUG.
To resolve this we currently have:
- The AI IOELEV in .
- The KL IOELEV in SYSBIN
- Copies of KLRUG in both . and SYSBIN
C; [CREL] 16 is timestamped 1981, but [CLIB] 16 is dated 1986.
Probably the latter was patched not to use the obsoleted UFA
instruction not supported by the KS10 machines.
