Apparently, Philips being late with concept of ISP rushed out with incomplete ISP.
what are you babbeling about, I NEVER had a problem.

Which is what puzzled a local programmer manufacturer
Maybe your "local programmer manufacturer" did not want to adhere to the Philips rules, too bad.

Having been through a major hassle once a long time ago with a client that used his kitchen table programmer and claimed no fault I totally understand the Philips attitude re. releasing programming specs
