The @ TECO binary is from the . directory on many backup tapes going
all the way back to 1971. The LPT 11 and MACTAP F68 sources come
unchanged from Peter Samson's "RandomSystem" DECtape. The TECO DUMMY
file is close to the undated SYSENG; TECODM 2 file.
The source files can be assembled with MIDAS 73, and linked with the
Muddle version of STINK. The link order is TECO DUMMY, LPT, MACTAP,
TECO.
This results in a binary that is identical to the original @ TECO with
a few exceptions:
- @ TECO has a loader in 20-37, and something in 776000-777777.
- MOBY is set to 174000 for 64K core, which results in MACDMP being
1777400 and MACCR being 177777. The @ TECO binary has it set to
DSKDMP at 777700.
- The buffer size in MEMSIZ is not the same.
- CONSTANTS has one additional zero at the end, shifting the rest
of the memory image up by one word.
Instead, use ITSNMS table.
- MAGFRM doesn't need to check machine name.
- But still knows about MC's config...
- Look up hosts in ITSNMS table instead of a hardwired one, and use all of the ITSNMS for *.
Use bits in .RYEAR/.RLPDTM result to return a local time zone,
TZONE (definable in SYSTEM;CONFIG).
TZONE should be the integer timezone offset (hours West of UTC)
Bit 4.4 => timezone known (otherwise, assume EST/EDT = 5)
Bit 4.3 => sign bit of timezone offset
Bits 3.5-3.1 => absolute value of timezone offset
If DSTEU is defined and != 0, calculate daylight savings time
according to European Union rules:
- starts at 2:00 (standard time) on the last Sunday in March,
- ends at 2:00 (standard time) on the last Sunday in October.
DUMP will scramble ACT and DUNG files written to the LCF directory.
This is no longer useful in protecting Zork files, so the code is
limited to the DM machine.
MACDMP MOBY1 has 340 support, but only works with the old PDP-6
microtape device. MACDMP 6U32 has both microtape and TD10 support,
but no 340 code. Both programs can be adjusted for core size.
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.
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.
This is the real source for DEVICE; OARCDV BIN, which uses the old
"ARC!!!" archive format. The previously reconstructed ARCDEV 66 can
be removed, and it was also the wrong version.
At the * prompt, type a file name and then Enter to load that file.
(Terminate with Altmode to first load the GT40LL "loader loader".
That file is currently missing.)
