BasicMicro no longer supports earlier IDE/compiler versions like 22xx, 53xx or 80xx. Each new revision existed because of bug fixes. All models' corresponding IDE/compilers now exist in Studio, which represent the latest in bug fixes. If you call or email BasicMicro for support in any of these earlier compilers, you will be referred to the forums. Studio is available as a free download at:
