Dear All, I am still using and old ST-4 as autoguider. Last week i was warned that the software in the control box is stored in an EPROM and that this information may decay. Lifetime period is assumed to be 10 years. It needs then to be refreshed. I could not find a source of a binary file in the web. Where can I get it ? It maybay that someone in the community has this program somewhere ao his harddrive- Revcommendations are highly welcome. best regards Christian
Wow, amazing that ST-4's are still out there hard at work. We do not have that available. I recommend reading the EPROM and saving the data. Then erase the EPROM and reprogram from the data file.
