I'd appreciate some advice on the following from any Olivetti M24 / AT&T 6300 experts :- 1. Olivetti (UK) tell me that the real-time clock is a MM58174, and is accessible at port addresses 70 through 7F. When using DEBUG, all I can read from 70-7E is FF, and 7F reads F0. This doesn't look much like a MM58174 according to my data sheet. Any descriptions, pointers, (or program source !) would be appreciated. 2. The reason I'm bothering with this is that I need to use MS-DOS 3.2 (for compatibility with other PCs around the site), and (according to Olivetti UK) the M24 version isn't available. The clock update is built-in to Olivetti versions of DOS (somewhere - I haven't found it yet) - hence the problem. Is 3.2 available for the M24 / 6300 yet ?
