- Notes for the 1.0 distribution of the Speccylator
-
-
- Three versions of the Speccylator program are included, all compiled
- *without* the DEBUG option and *not* including debugging information
- such as labels:
-
- * `Speccylator'
-
- Runs on MC68020 and compatible processors. Does full Z80
- emulation. Needs at least 433 kByte RAM, of which about 43
- kByte is "chip memory".
-
- * `Speccylator-00'
-
- Runs only on MC68000 or MC68008 processors (put otherwise,
- it does not run on MC68010 and compatible processors). In
- all other aspects it should be equal to the above version.
-
- * `Speccylator-00q'
-
- The "Quick-and-dirty" version. Like the `Speccylator-00'
- program, it runs only on MC68000 or MC68008 processors, but
- the executable program is almost 32 kByte smaller, and it
- dynamically allocates 64 kByte RAM less than the normal
- versions; in other words, it needs at least 337 kByte RAM.
- This version does not include emulation of BCD flags,
- cannot detect interrupts between iterations of Load and
- Repeat instructions, and more importantly, does not protect
- the ROM memory area from being written to, and cannot cope
- with modified code (the term used in the widest possible
- sense).
- The speedup of these "unfeatures" is significant, but many
- ZX Spectrum programs will not work. Do not use this program
- for producing serious work in a ZX Spectrum environment,
- since a crash can occur at any time.
