 		 #173020 - OP's computer definition
Responding to: ???'s previous message
Andy Neil said:
What, exactly, do you mean by "computer"?


I think the OP mentioned 'early sinclair computers' somewhere earlier in the thread http://www.8052.com/forum/read/172999

So I guess he's referring to simple computers like the ZX80/81/spectrum systems (unlikely
he's referring to the Sinclair QL! :-) Therefore..

Andy Neil said:
There are far better architectures available for "computer"-type applications - some at similar costs to comparable 8051-derivatives...


A suitable 8051/52 derivative can still be considered this case, though I really don't think a plain-old 89S51 would 'cut it' on the video side..

Of course, those who have moved on to ARM can consider the new Cortex-M0!
