- Micro-Guider 5: a telescope to computer interface device built, tested, and ready to use, which is designed to work with the Earth Centered Universe Pro and other popular planetarium software.
- The Micro-Guider III: a do-it-yourself telescope-to-computer interface has been discontinued due to the lack of pcbs. The much-improved Micro-Guider 5 replaces the MGIII. Many of the parts for the MGIII are still available for those who need them.
- The Micro-Guider I has been discontinued since the pcbs are no longer available and a critical part has become hard to find. The original documentation in Adobe Acrobat format, for those still interested, is available here.
- The Intel format hex files for the MGI and MGIII eproms are here.
