Migrate From 87C750

I am involved in selectively redesigning some legacy robotics hardware, a part of which uses an embedded Phillips 87C750 microcontroller, datasheet: http://www.nxp.com/acrobat_download2/datasheets/83C750_87C750_2.pdf.

We don't mind reusing this part if it is current but I can't find a statement regarding it's current production status. I've attempted to contact nxp but no response.

We have firmware already written for the application that uses this microcontroller that we would like to reuse without modification if possible.

So my question is:
Does anyone know if this part is still active, and if not - what microcontroller could I use that would accept the existing firmware without modification? Ideally it would also be a pin compatible part but this may be asking too much.

Thanks.

Thanks HappyCactus. Your comment has led me to http://www.nxp.com/products/eol/ which in turn has suggested LPC762 or LPC932 as possible replacements. At this stage, the 87LPC762 looks promising.
