96fccc355a Block loader for TT2500. 
The 2500 bootstrap ROM expects to receive a block loader first, which
will run and recieve the actual payload which is the microcode and
font data divided into blocks.

3255fc5188 Microcode for the TT2500. 
The assembler will recieve a GC-OVERFLOW interrupt.  Other TT2500
files set the GC-OVERFLOW variable to a dummy function, which seems to
appease the interrupt.

Since the TVDIS code was written before backquote was introduced to
Maclisp, it uses comma characters without quoting.  To accomodate this
a call to SETSYNTAX overrides the new syntax for comma.

4af63f786b Assembler for TT2500. 
The assembler is written in Maclisp.  The main entry point is ZAP
which expects a symbol with a value cell pointing to the source code.

47fb5ba074 Don't start display right away.

DSTART will be called later, honoring the updated GTTY value.

f31a4f1f57 Make DUMP's "LCF hack" only work on DM. 
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.

1a6115e949 Fix Muddle's CLOSE not flushing the output buffer. 
There were two problems here:

- The FOPEN code in 56 uses new C.DISK/C.TTY flags to keep track of the
  channel type, so it knew what to do when closing the channel. The
  TOPS-20 open code had been modified to set these, but the ITS code
  hadn't, so CLOSE was assuming all channels were network channels.

  Fix: set those flags in ODSK and OTTY, as TOPS-20 does.

- The BFCDSK flush routine had been modified to use byte pointer writes
  to write the last incomplete word for both TOPS-20 (SOUT) and ITS
  (SIOT). But on ITS, SIOT only works in unit mode, and Muddle opens
  files in block mode.

  Fix: restore the working code from Muddle 54 for writing the last
  word. The only difference is that BFCDSK can now be invoked with the
  leftover byte count (C) being zero, so it needs to check at the
  start to avoid duplicating the last word in that case.

56404ba0e4 Update Lisp Logo for new GC-DAEMON list format. 
The format of the list passed to GC-DAEMON has changed.  LLOGO expects
a list of "(space old-free . new-free)".  The new format is "(space
old-free new-free old-size new-size)".

1f66578276 Remove references to BIBOP from Lisp Logo. 
The Lisp Logo loader conditionalizes some things on the BIBOP feature.
Maclisp still uses BIBOP memory management but the feature symbol went
away in 1980.  Since Lisp Logo has unconditionally been ported over to
NEWIO, the BIBOP checks are removed.
