2025-12-29: I have restored the wiki to a backup from the end of November. Starting in September 2025, accesses went form the 800MB-1.2GB range per month to 26GB in September, 42GB in October, and 70GB in November with most accesses originating from China. As soon as I realized what was causing all the access problems in November, I shut it down (it had reached 36GB by then) behind a password/login screen. The database had gotten corrupted, and I tried a restore from just before the spike in access but that didn't work. Thus, end of November. I still have the other daily backups so if there were any important additions in December, let me know and maybe they can be recovered. - Allen H.
EPROM Programming
I don't know how many versions were made, but mine runs off a single +5 volt supply. It does not use batteries to get the programming voltage, it uses a DC-to-DC voltage contverter to generate the +12V, +21V, or +25V programming voltage. By using a DC-to-DC converter, it allows it to work on all versions of the coco. This IS compatable with the CoCo3.
repair tip: I had my DC-to-DC converter go bad (I broke it, by overloading it, it was an accident), and I simply tested the 4 transistors and replaced the bad one(s). With the price of these small signal transistors, you're probably better off to just replace all of them.
I will try to get a picture of mine posted before too long. Someone contact me if I forget.
