 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 version of Z80, fully compatable.

...
 NEC D770008AC-6 
NEC, may be an 8bit ADC.

...
 NEC D4364C-15L 
8x8k dynamic ram 150ns 

...
 NEC D8251AC 
USART, serial same as intel 8251A

...
 NEC D449C 
2kx8 CMOS static ram 450ns and two chip enables
and retains data down to 2V in standby mode.

...
 AMD AM9511A-1DC 
AMD arithmetic procesor

...
 Sharp LH0081A
Sharp LH0082 
  I think these are Opamps or maybe line drivers.

...
 Intel 8339
Intel 8325
Intel K3235001 
Intel 83xx is likely a 1983 date code. The Kxxxxxx is a 
mask/date code for a rom based part.  None of those cross 
to any part I can reference and my intel databook set is 
complete from 1977 through 1993.  Those are likely 
"house numbers" if they are not date codes.

Since no other rom parts were listed I'd assume they are 
ROMS.

...
 Zilog Z8442BPS 
Z80 SIO,  dual serial 

...
 Zilog Z8430BPS 
Z80 CTC, timer counter chip
