That sounds very like the ICL 1900 mainframes where I first
learnt assembler (I'd previously learnt Algol 60 at uni). The 1900 only 
had two hardware registers, which held datum and limit addresses for the 
active program. Programs were a contiguous block of memory - task 
switching was done by changing datum and limit to point at the next 
program to run. Each program had its own register set because they were 
the first 8 words of each program, with word +8 being the PC and, since 
all addresses in a program were relative to datum, programs could be 
swapped in, out or moved in memory very simply.

Motorola 6809 and 68xxx chips partly shared these characteristics: 
although the registers etc were a single set implemented in hardware, it 
was possible to write a program using only PC-relative addressing, so 
again it could be swapped in or out and moved in RAM by the OS between 
its active time slices. Microware's OS-9 operating system (it ran on both 
6809 and 68xxx chips) could and did do this because all programs written 
for it used PC-relative or indirect addressing.

Not an unusual arrangement in those days. The PDP-10 had the same (with 
16 x 36 bit registers).

In fact, in the more expensive systems (e.g. 1904) the registers 
(accumulatots, call them what you will) did appear as the first eight 
words of memory, but were in reality hardware based.

In those days IIRC CPUS were built from logic chips, and RAM was not the 
same thing.

Only when single chip CPUS appeared wasit woirth puttng some RAM on te 
chip itself and calling it 'registers

PDP11 used 4 X 4 bit TTL register chips to make its 8 X 16 registers.

Also in PDP11, the hardware registers were addressable as though they
were memory locations on the I/O page.

In *some* PDP-11s....

I never dealt with anything bigger than a 1903S when writing PLAN or 
using the macrogenerator. Later, when I was a G3 system programmer, I 
don't think I touched code at a lower level than GIN (and usually with a 
layer or two of macros below anything I got my fingers on), COBOL and 
Algol68R. I only found out about the hardware registers in the bigger 
machines fairly recently, but even then I'd guess that there were many 
less hardware register sets than running programs and that program 
switching would involve copying the accumulators + pc set between the 
hardware registers and the program image.

BTW do you know how much of lower program memory was supported by 
hardware? Was it just the accumulators + PC, or was anything else, e.g. 
the option switches (word +9?) also put into a hardware register?

But that's what happens in practically *every* register based machine. 
Except that they're stored in a process control block, usually.

(excepting machines that have two sets - at the low end, the Z80, higher 
up something like the PDP-11, which had one for each mode)

Just the accumulators, and presumably the PC. I don't actually think it 
*was* the PC, it was just somewhere to stash it between times.

The PC gets changed as an integral part of executing every instruction, 
so the speed-up you'd get from putting that in a fast hardware register 
could be more important than moving the accumulators into fast hardware. 
Doing the same for the CC register is also more important than moving the 
accumulators. Here's my basis for saying that:

- the PC register will be changed for every instruction, so gets accessed
  much more often (one read, one write per instruction executed) 

- the CC register probably gets more accesses than any one accumulator
  because every conditional jump, loop instruction and arithmetic opcode
  reads it and some percentage of arithmetic opcodes write to it

- on average each accumulator gets accessed by approx 10% of instructions
  (less than 12.5% because not all instructions access an accumulator)

I'm not disagreeing with you. I am saying that the PC (and other context 
such as CC and accumulators) were NOT, in  practice, stored in memory.

But on a context switch, that is where they were stored.

Depends what you mean by memory, which is I thought the whole point of 
the discussion. Registers *are* memory. Fast local memory. Before LSI it 
would likely as not been static RAM. Even a D type register is 'memory'.

The evolution of single chip processors, initially with onboard RAM for 
registers, later with onboard ROM for microcode, and latterly with 
onboard cache to shadow offboard DRAM  is a story that can be read many 
ways.

You're splitting hairs. Let's use the terminology 'memory' for the large, 
immediately accessible memory that, in those days, was either core or (if 
you were lucky) MOS or similar.

Registers are in the CPU and a LOT faster. Just because the registers 
were associated with locations in that slower memory, doesn't mean they 
were actually stored in it (except at a context switch, perhaps). That's 
my point.

The advantage of making the memory system 'lie' and allow access to the 
registers as 'memory' is quite useful, though. I've seen tight loops 
copied to such registers and then executed.

We're in agreement.
 
I thought you were saying that, when a program image became the active 
process accumulators were copied to hardware registers and saved back to 
the image when control was switched to another program image but you 
weren't certain whether the PC and CC registers were transferred with 
them. All I'm adding is that, if only some of theset (accumulators, PC 
and CC) were transferred, then it would be better to move PC and CC 
rather than the accumulators. If I've understood Denis correctly, that's 
more or less exactly the Sigma did, leaving the register bank as part of 
the program image unless it was an expanded machine with multiple 
hardware register banks.

The active PC, I think, should be a real hardware counter, as opposed to
an ordinary register, with hardware parallel load for jumps.  Most
instructions are not jumps, so it is incrementation that should be
optimised.

The PDP11 instruction set required pre-decrement of the PC to work; but
I imagine that -(PC) occurred so rarely that it could be handled by
calling an interrupt in the OS code.  But 014747 was an interesting
instruction.

FYI : I too started with Algol 60, using just an ASR33.  Transfers
to/from the computer were, IIRC, by bikenet.  Subsequently, I became
acquainted with one of the authors of the Algol 60 report.

The TMS-9900 chip from TI had three 16-bit register internal to the CPU: 
Program counter (PC), Status register (ST), and Workspace Pointer register 
(WP).

The Workspace Pointer held a pointer to memory where 32 bytes held what was 
used as the general purpose registers of the CPU.  Changing context involved 
changing the WP to point to a new register set... among other things.

	Sigma task switch was done via an "eXchange Program Status Doubleword",
which held the new program counter value, condition codes, and (for
expanded machines) an indicator for which bank of registers to activate
(apparently one could add multiple 16-register banks to the processor).

	No standard stack register -- though one could dedicate a register to
do stack operations, the common (FORTRAN/non-recursive) paradigm turned
into indirect references via subroutine link register (also not a dedicated
register, one specified the link register in the call instruction).
Arguments were passed by...

	call,<lr>	<subroutine>
	data		<address of first argument>
	data		<address of second argument>
	...

subroutines would then copy the addresses by indexing off the <lr>, ending
by incrementing the <lr> by the number of arguments.

	Sigmas were (in)famous for having something like 224 interrupt vectors
(when IBM 360/370 only had 7 and had to poll to determine which device
interrupted). Each interrupt vector basically held a program status
doubleword, so an exchange PSD made for fast response.

	The "big" assembler for them didn't even have a hard-coded instruction
set... Programs started with a "system ..." declaration which basically
loaded a macro definition file for all the opcodes. Out of boredom one day,
I wrote a "system" file that would generate absolute 8080 code. (I forget
the instruction format declaration but something like:

MOV	S:SIN,2,3,3		x'01',AF(1),AF(2)

"Form an instruction with three fields sized 2-bit, 3-bit, 3-bit using
constant x01 for first, argument field 1 for second, argument field 2 for
third" (also had LF and CF for label and command field -- presuming one had
defined constants for the 8080 registers the above made

		MOV	H,B

a valid instruction to the assembler))

The 1900 was equally crufty. It also had no stack pointers and no 
dedicated subroutine call register either: A subroutine call at its most 
basic looked something like this:

   LDA 4 #PARAMBLK   [ pointer to arguments starting at PARAM
   JSR 3 MYSUB

which passed the pointer in accumulator 4 and left the return address in 
accumulator 3. Or, if arguments were under 24 bits you'd just put them in 
accumulators, Trivial example:

       LDA 6 VAL1
       LDA 7 VAL2
       JSR 0 ADDER
       ...
       ...
ADDDER ADD 7 6    [ Add accum 6 to accum 7
       RTS 0      [ Return

The 1900 was quite efficient at running COBOL (claimed 6 machine 
instructions per COBOL Procedure Division statement) but was less good at 
handling stack based languages like Algol60 or 68. I don't recall seeing 
even a mention of a Pascal compiler and the first C compiler was barely a 
gleam in Kernighan & Richie's eyes.

The nearest to that I've got was the General Purpose MacroGenerator, 
which came out of Cambridge Uni and could, among many other things, be 
used as a fairly basic assembler.

And, of course, Lex & YACC which are wonderful once you get your head 
round them though you can only get C out of it. 

However, CoCo/R is an even better: its a  bit easier to use because both 
lexer and parser are parts of one program, so there's only one input 
syntax definition file to write, it is available written in several 
languages (C,C++,Java,Pascal, Python,...) generates code for the language 
it is written in, and if you don't like the template file for its output 
its trivial to write another. 

If you have a need for this type of program, I'd say Coco/R is the one to 
go for.
