Ports of Apache and PHP have been made to it.

One database available for it is SESAM, for which a PHP 3 extension exists (http://www.php.net/sesam). Other available databases are Adabas from Software AG and IDMS from Computer Associates and Oracle from Oracle Corporation.

BS2000 may run under the VM2000 hypervisor.
