6501
(foldoc) | 6501
An eight-bit microprocessor, the first sold by
MOS Technology. The 6501 pin-compatible with the
Motorola 6800 and was the first member of the 650x series.
It had an on-chip clock oscillator.
See also 6502.

6502
(foldoc) | 6502
An eight-bit microprocessor designed by {MOS
Technology} around 1975 and made by Rockwell.
Unlike the Intel 8080 and its kind, the 6502 had very few
registers. It was an 8-bit processor, with 16-bit {address
bus}. Inside was one 8-bit data register (accumulator), two
8-bit index registers and an 8-bit stack pointer (stack
was preset from address 256 to 511). It used these index and
stack registers effectively, with more addressing modes,
including a fast zero-page mode that accessed memory locations
from address 0 to 255 with an 8-bit address (it didn't have to
fetch a second byte for the address).
Back when the 6502 was introduced, RAM was actually faster
than CPUs, so it made sense to optimise for RAM access
rather than increase the number of registers on a chip.
The 6502 was used in the BBC Microcomputer, Apple II,
Commodore, Apple Computer and Atari {personal
computers}. Steve Wozniak described it as the first chip
you could get for less than a hundred dollars (actually a
quarter of the 6800 price).
The 6502's indirect jump instruction, JMP (xxxx), was
broken. If the address was hexadecimal xxFF, the processor
would not access the address stored in xxFF and xxFF + 1, but
rather xxFF and xx00. The 6510 did not fix this bug, nor
was it fixed in any of the other NMOS versions of the 6502
such as the 8502. Bill Mensch at Western Design Center
was probably the first to fix it, in the 65C02.
The 6502 also had undocumented instructions.
The 65816 is an expanded version of the 6502.
There is a 6502 assembler by Doug Jones
which supports macros and conditional features and can be
used for linkage editing of object files. It requires
Pascal.

650x
(foldoc) | 650x
A family of microprocessors from {MOS
Technologies}, based on the design of the Motorola 6800
(introduced around 1975). The family included the 6502 used
in several early personal computers.

6510
(foldoc) | 6510
A successor to the 6502.
The 6510 was used in the Commodore 64C. Successors included
the 8502 used in the Commodore 128 line.

65816
(foldoc) | 65816
An expanded version of the 6502, with which it
is compatible. It has 16-bit index registers and {stack
pointer}, a 16-bit direct page register and a 24-bit {address
bus}. Used in later models of the Apple II.

Commodore 64DX
(Or Commodore 64DX, C65, C64DX) The last 8-bit
computer designed by Commodore Business Machines, about
1989-1991. The C65 boasts an ugly collection of custom
integrated circuits which makes even the Amiga hardware
look standard.
The core of the C65 chipset is the CSG 4510 and {CSG
4569}. The 4510 is a 65CE02 with two 6526 CIAs. The
4569 is equivalent to a combination of the 6569 VIC-II and
the MMU of the Commodore 64. The C65 also has a {DMA
controller} (Commodore's purpose built DMAgic) which also
functions as a simple blitter, and a floppy controller for
the internal Commodore 1581-like disk drive. The floppy
controller, known as the F011, supports seven drives (though
the DOS only supports 2). The 4510 supports all the C64
video modes, plus an 80 column text mode, and bitplane
modes. The bitplane modes can use up to eight bitplanes, and
resolutions of up to 1280 x 400. The palette is 12-bit
like the Amiga 500. It also has two SID's (MOS 8580/6581)
for stereo audio.
The C65 has two busses, D and E, with 64 kilobytes of RAM
on each. The VIC-III can access the D-bus while the CPU
accesses the E-bus, and then they can swap around. This
effectively makes the whole 8MB address space both {chip
ram} and fast ram. RAM expansion is accomplished through
a trap door slot in the bottom which uses a grock of a
connector. The C65 has a C128-like native mode, where all
of the new features are enabled, and the CPU runs at 3.5
megahertz with its pipeline enabled. It also has a C64
incompatibility mode which offers approx 50-80%
compatibility with C64 software by turning off all its {bells
and whistles}. The bells and whistles can still be accessed
from the C64 mode, which is dissimilar to the C128's
inescapable C64 mode.
Production of the C65 was dropped only a few weeks before it
moved from the Alpha stage, possibly due to Commodore's cash
shortage. Commodore estimate that "between 50 and 10000"
exist. There are at least three in Australia, about 30 in
Germany and "some" in the USA and Canada.

ibm 650
(foldoc) | IBM 650
A computer, produced ca. 1955 and in use in the
late 1950s, with rotating magnetic drum storage and {punched
card} input. Its memory words could store 10-digit decimal
numbers and each instruction had two addresses, one for the
operand and one for address of the next instruction on the
drum.
SOAP was its (optimising) assembler. Languages used on it
included BACAIC, BALITAC, BELL, CASE SOAP III, {DRUCO
I}, EASE II, ELI, ESCAPE, FAST, FLAIR, FORTRANSIT,
FORTRUNCIBLE, GAT, IPL, Internal Translator, KISS,
MITILAC, MYSTIC, OMNICODE, PIT, RELATIVE,
RUNCIBLE, SIR, SOAP, Speedcoding, SPIT, SPUR.
