Am I missing something here?Why don't you order it burned with a bootloader ? Most distributors have automated part programmers, and can deliver the chip with your bootloader on the part for little, or no price increase over the raw part.
Microchip PICs don't come pre-installed with a bootloader firmware??

I said all the Philips VARIANTSNah Ian, you'll have to do better than that :-) The 8052 originates from Intel, so if you say "....8052 variants from Philips. All come.....", you don't say "some 8052 variants from Philips". This is standard math basics as taught on high-school. The way you said it, you implied that all variants from Philips have a bootloader. Damn, this is bad for my headache..... Meindert

Damn, > this is bad for my headache..... > > MeindertThink again - I did not say all Philips 8052 devices have a boot ROM loader I said all Philips 8052 VARIANTS i.e. variants on the original 8052 from Intel and not the straight copies.

And I am still not convinced. The Philips 80C451 has no bootloader and is not a direc copy of an existing Intel type..... :-)=) Meindert
