I have been scrounging for parts for my computer, and I believe I have hit
the jackpot. A friend of mine set me up with some older Seiko control system
boards, various revisions, from the late 80s. On them are many ICs,
including RAMs, Z80 CPUs, and PIOs, as well as some AMD Arithmetic
processors, a Z80 SIO/2, and other various components. I want to try to make
my computer from these components. Can anyone point me in a good direction
for the datasheets, preferably online, for these mostly obsolete ICs? Some
of them I don't even know what they are, and some I cannot find online,
presumably because they are obsolete. Here's a partial list of them:
NEC D780C
NEC D770008AC-6
NEC D4364C-15L
NEC D8251AC
NEC D449C
AMD AM9511A-1DC
Sharp LH0081A
Sharp LH0082
Intel 8339
Intel 8325
Intel K3235001
Zilog Z8442BPS
Zilog Z8430BPS
Thanks for any help

NEC D780C
This is a Z80 compatibe CPU.
NEC D770008AC-6
I believe this is the low power
version of the above
NEC D8251AC
USART - Universal Syncronous
Asynchronous Receiver
Transmitter
AMD AM9511A-1DC
Processor
Intel 8339
Intel 8325
Sure those aren't date codes?
Zilog Z8442BPS
Serial I/O controller
Zilog Z8430BPS

Some of the ones I have on hand do both.

You could have a look here, for starters:

:-)
I suspect that second one is a pretty generic 64K DRAM, the next one an
8251...

AFAIK it's an exact equivaletn of a Z80 CPU. I've never found a circuit
that works with one and not the other.
NEC D770008AC-6
No idea
NEC D4364C-15L
I guess that's a 64K*1 DRAM, similar to a 4164
NEC D8251AC
Equivalent to the Intel 8251, National Semiconductor INS8251, etc. It's a
USART
NEC D449C
No idea
AMD AM9511A-1DC
AMD floating point chip
Sharp LH0081A
Sharp LH0082
No idea
Intel 8339
Intel 8325
Are you sure you've not given me the date codes?
Intel K3235001
No diea
Zilog Z8442BPS
Z80-SIO I think Dual serial interface chip
Zilog Z8430BPS
Z80-CTC COunter/Timer chip
