According to the text file included with the zip archive, the BASIC-52 code is Freeware, and this software is not supported by Intel nor Warranteed in any way.
The object and binary files included were NOT produced from this source, but extracted from a known good, factory masked 8052-BASIC chip using the included rom-dump.bas program code. The code allows the 8052-BASIC chip to perform a self-dump of its rom region. I created this program because when I attempted to assemble the included source code, I received 50 errors which I did not attempt to resolve, opting to just dump the contents of the factory mask rom instead, knowing THAT code was good.
The binary or object files may be programmed into any 64k external memory device (prom, eprom, eeprom, sram, etc.) and configured for code memory region on any 8052 series microcontroller with at least 1k of sram configured for external memory addressing, up to the 64k limit.
The factory mask ROM versions of the 8052-BASIC are no longer going to be produced by Intel. Other companies are producing the part, however I am not sure if the rom code is identical. The included rom-dump.bas code may be used with other variants of the MCS-51 series BASIC controllers to obtain possibly other versions of 52-BASIC.
