Minor issue with jr-IDE RTC

I've (almost) finished my jr-IDE build (see link below), but I'm running into an issue with RTC.COM. The build I am using is from https://www.retrotronics.org/svn/jride/trunk/prebuilt/jr/ but it complains that options /P and /O are exclusive even when I don't state /P or /O in the command line.

jr-IDE C4, C9 & C11 voltage rating?

I'm currently in the process of building a jrIDE and the BOM description for C4, C9 & C11 states a 50V rating for the 22uF capacitors. Both the Mouser and Digikey links utilize 6.3V parts.

I assume the 6.3V part is OK, but I thought I'd check.

Re: Issue with two different PCjrs - looking for troublesh h

This is my first post on here, but I recently got a batch of 8 PCJrs. 6 of them exhibited the issue discussed in this thread. The tantalum capacitors next to the <olex connector on the 5.25" drive were shorted across the 12V line, simply replacing them with some electrolytic 4.7uF 50V capacitor...
