Hello to everyone from italy!Some days ago i went to the sunday market and i found a bunch of old mcu and cpu.I dont know almost anything but i would like to program them with arduino.
HERE IS A LIST OF THEM:
Nec D80C42C-315
Nec D8085AC
INTEL P8748H
TOSHIBA TMP8048
TEMIC ACERPERAP3509M
TMS70C02NL (I HAVE 3 OF THEM)
P8742AH
TMP8048P
MC68B45P
AMSTRAD 40042
MOSTEK MK3880N-IRL
Z8420B1
NEC D8085AHC-2
D8085AC
INS8048-6
Can you help me?
Have you got the technical datasheets for those microprocessors with details of the assembler commands they understand and details of how to connect to them to upload a program?
GaryP:
Curious...
-Have you a hardware for connecting these CPU's?
-With Arduino, you mean Arduino IDE or Arduino hardware
well,i have a mega 2560 and a uno.I want to program mcu in any way,is not important how i program them.

...R
i have datasheets,but i dont understand everything...:-()

The 80xx microcontrollers are chips with internal ROM memory that isn't reprogrammable. They MIGHT be usable with an external program memory chip and latch (like the 8051) and a pin tied appropriate.

The 87xx chips are theoreticaly UV-eraseable and reprogrammable. If theses are chips with a glass (quartz, actually) window, you can erase them with a short-wave UV source and reprogram them using an appropriate parallel programmer (it probably requires weird high voltages on multiple pins.) If they don't have the window, they're in the same state as the 80xx chips. The 804x are some of the very first microcontrollers, probably really unpleasant to deal with.

This is a CRT controller peripheral controller.

The 8085s are microprocessors. They need external RAM and Program memory, and a bus (latch chip.) And peripheral chips, if you want more than one bit of IO. (The 8085 has a single input bit, and a singe output bit.)
MOSTEK MK3880N-IRL
This is the Mostek version of the famous Z80 microprocessor. Like the 8085s, it requires quite a bit of external circuitry to make it work. (You can build a 4-chip Z80 system these days, using an AVR to simulate the IO and bootload code into RAM. It's pretty neat. Z80-MBC2: a 4 ICs homebrew Z80 computer | Hackaday.io
