'[OT] 6502 question'

Greetings to all,

I 've got an off-topic question about the 6502,6510 8-bit
microprossesors. Are they still in existence or in production? If yes,
please name some suppliers or manufacturers.

Thank you in advance,

Nickolas

Jameco still sells the 6502, it's on page 6 of their catalog.
1-800-831-4242
They've just started carrying Microchip as well... good for them!
(gotta stay on topic ;-)

Nick,

I am an old 6052 coder and HW designer.   Only ther "core" remains.
The Gameboy uses a 6510 variant.   I have 6502s, 6510s and 6522s 40p
DIP plastic chips lying around.   Plus the ASM development systen the runs
on CPM - yea what a fossil - but a 2 MHX 6502 and 8255 in 1981 was a
marvelous pairing and was the core controller for a soup can factory...
Rockwell was the original manufacturer, I believe there is still old stock
from a Japanese manufacturer that had a 4 or 8 MHz version...  Look into
Jameco - they carry mid 80s stuff still...  What a joke...

Nope, the gameboy uses a z80 variant.

What Z80 variant would that be?

It's a LR35902, according to the schematic at

       http://home.HiWAAY.net/~jfrohwei/gameboy/gameboy1.gif

It's basically a stripped-down Z80 (no port IO, no string instructions,
and no alternate register set). It also includes all the sprite/sound
hardware. I don't know if this part is publicly available - I suspect
it's a custom Nintendo thing.

Cheers,

Ben

It is a real customised job with added instructions.
I remember there were a stack of new DJNZ's for
many different registers. There was added hardware to
scan the LCD screen too.


I had a friend who wrote/writes? Software for it and he
showed me all the development stuff. (but I wasn't meant
to see any of it so I didn't get to take notes.)

I take it some one is looking for a 6502.

If so i've got one spare that i could post to them.  It's just sitting there
doing nothing.

Free to a good home.

Ricoh, of all 'people', lists a 65C02-equivalent CPU in their
data book.  Basically just a 6502 with (if I remember right)
a few new instructions:

       bit set/clear
  branch on bit set/clear
  STZ (store zero--works with same addressing modes as STA)
  BIT #imm
  and a new addressing mode: non-indexed indirect

but otherwise the same 6502 as you've grown to know and love.

Hi,

I would like to thank all people in PICLIST that replied to my 6502
information request and for sharing valuable information with me. Their
help was really great :)
Thanks again.
