According to the ProDOS Technical Ref. Manaul, p. 106: To support clock cards that do not follow the ProDOS protocol defined above... All that your code needs to do is get the time from the clock card, convert it to the ProDOS format, and store it in the date and time locations in the global page. I have the AE Serial Pro (the serial card + clock). The card conflicts with my Saturn 128K memory card and renders the Apple unusable if the Saturn and Serial Pro are in the same computer. It also does NOT follow the standard alluded to by Mr. Owen (the one listed in the Tech Ref on p. 105). I have also found that there is not one location (that I can find) to put my newly acquired NSC in my Apple II+. Either my peripheral cards have no ROM, or have 24-pin ROMs, or there is no space for the over-sized NSC. The NSC requires a 28-pin ROM to operate properly. As a result of these shenanigans, both my Serial Pro and NSC are OUT of my computer. <SIGH>. [david] -- !======= David Douthitt :::: Madison, WI =======!== The Stainless Steel Rat ==! !
