<p>WormFood: initial page</p> <hr /> <div>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.<br /> <br /> 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.<br /> <br /> I will try to get a picture of mine posted before too long. Someone contact me if I forget.</div>

<p>WormFood: Initial page</p> <hr /> <div>The 'CoCo XT' is an interface that allows the CoCo to use certain IBM compatable MFM and RLL controllers, for ST-506/412 interface hard drives. The 'CoCo XT-RTC' is the same interface with a real time clock.</div>
