This is bad, really bad.
First of all this article suggests an accumulator processors has one accumulator (which 6502 did). However numerous examples are contrary to this such as
With 2 accumulators you need only a single bit in the instruction to indicate what accumulator is to be used. 68000 has a lot of data registers, and those are not called accumulators, so the article should state clearly where the limit is. Seems the limit is around 4 (ARM Piccolo)
SWEET16 has one accumulator and 15 other registers, a wealth closer to 68000.
Next is the link to accumulator-based architecture which goes to PDP-8, specifically the section Legacy_of_accumulator-based_architectures which no longer exists. Is there any reason why this has to be split up?
Also it seems a bit lacking that the multiply-and-accumulate is not mentioned.
All in all an article in need of an overhaul. --22:47, 22 February 2009 (UTC) Amended --21:30, 23 February 2009 (UTC)
Hopefully such an overhaul will also disambiguate further, since the term "accumulator" in programming applies to a variable in which values are accumulated... 63.249.90.205 ( talk) 00:55, 25 June 2010 (UTC)

#Accumulator machines says Almost all early computers were accumulator machines with only the high-performance "
supercomputers" having multiple registers.
However, the
IBM 7070
[1] had three accumulators, the
UNIVAC 1107
[2]
[a] had 16, the
DEC
PDP-6
[3]
[b] had 16 and, of course, the
IBM System/360 had 16 general registers. The 1107, PDP-6, S/360 and their successors were popular in the 1960s and 1970s, and that era was dominated by machines with multiple accumulators. So where is the cutoff for "early"? --
