Machines I'm curious about:
- Acorn Archimedes
- Psion hand-held
- Apple II GS
- Newton
- Anything else you use that's NOT 68000-based, NOT Intel-based, and does
not have full 32 bit registers and arithmetic operations.
What I want to know about them:
- What's the CPU?
- How many registers does it have?
- Are they general-purpose? (e.g., 68000: yes Intel: no)
- Are the registers 16 bits or 32 bits wide?
- If 16, does the processor support doubling up two registers
for 32 bit arithmetic? I.e., can you put the low 16 bits
in register A, the high 16 bits in register B, and then
do a single instruction that does a 32 bit ADD, AND, etc.
- How fast is the CPU? (MIPS, or SPEC -- approximate)
No need to post this stuff; just email and I'll summarize if anyone else
cares. Thanks for your help in advance.
