Microsoft catalogs from the 1980s also showed the availability of BASIC-68 and BASIC-69 for the [[Motorola 6800]] and [[Motorola 6809|6809]] microprocessors respectively, running the [[FLEX (operating system)|FLEX operating system]]s, and also mention OEM versions for [[PerkinElmer|Perkin-Elmer]], [[Ohio Nuclear]], [[Pertec]] and [[Societe Occitane d'Electronique]] systems.<ref>[http://archive.computerhistory.org/resources/access/text/2009/12/102665404.05.01.lg.pdf "MICROSOFT Software Catalog"], c1980, Computer History Museum</ref>
It seems likely this is what is also the basis for the Microsoft/Epson BASIC in the [[Epson HX-20]] portable computer, which has two Hitachi 6301 CPUs, which are essentially a "souped up" 6801. Most of the core features in BASIC-68 and BASIC-69 were copied directly from BASIC-80.{{Original research inline|date=February 2019}}

BASIC-69 was notably also licensed to Tandy, where it formed the nucleus of [[Color BASIC]] on the [[TRS-80 Color Computer]].{{Citation needed|date=February 2019}} Not to be confused with [[BASIC09]], a very different BASIC created by [[Microware]] as the main language for its [[OS-9]], the other OS available on the Color Computer (Microware also wrote version 2.0 of Extended Color BASIC when Microsoft refused to do it). Microsoft BASIC was also included in the Dragon 32 / 64 computers that were built in Wales and enjoyed some limited success in the UK home computer market in the early 1980s. Dragon computers were somewhat compatible with the Tandy TRS-80, as they were built on very similar hardware.
