 		 #156988 - The P/S2 interface is not that bad
Responding to: ???'s previous message
But it does look like he wants to make a little PC.
The LCD is not that hard, the keyboard, same. Talk to EEPROM or FLASH same. Now moving up, BASIC52 fit into 8K. 64K chips are common now.

Add an assembler is a lot more work. Then comes the issue where are you going to run from? The 8052 does not fully support relative instructions. The code must run at the address it is coded. Plus the Memory spaces are separate. They can be combined but then you get Only 64K not 64K Code + 64K RAM. On the plus side newer chips have FLASH. So you can write to that.

All that he said is do-able. But some of it is a bit of work.
