The OSI 8K version of Microsoft BASIC had a famous bug in the garbage collection routine, which would cause the system to crash when running certain string-intensive programs. Several fixes have been published, generally involving re-burning one of the BASIC ROMs (ROM#3). Here are the ROM images, suitable for burning to 2K EPROMS. They can be concatenated to an 8K EPROM if desired.
Premier Publications offered a series of enhanced BASIC ROMs that significantly extended the functionality of the ROM BASIC. Many thanks to Mike in New Zealand for contributing these! Mike contributed the ROMS and the accompanying information in the table below. Any additional documentation would be much appreciated.

I have not been very lucky in my attempts to recover code from the few surviving old cassettes and disks I have. Therefore everything in this section has been lifted from the various links. I'd like to comb through the code and write little summaries of the programs and create a little index. If you try some of these, please send me your comments.
By the way, the programs below are in cassette-dump format, meaning that each line ends with a <CR> and several nulls. This is reccomended if you plan to encode the files for cassette input, or upload via the serial port, since BASIC needs a few moments to digest each input line. If you wish to remove the nulls (for example, to edit under Unix/Linux or DOS), you can use the 'tr' command, standard on unix/linux, and available for DOS/win. The following removes nulls and CRs:
tr -d '\000\015' < ASM.BAS >tmp
for i in *; do tr -d '\000\015' < $i >tmp; mv tmp $i; done

FBASIC is a compiler for a subset of Microsoft BASIC. Some of the missing features are:
Some extensions are:
