|Here's another probably unimportant question about obsolete technology...|
I have a couple socket-7 boards with RTC (real time clock) modules (the kind with the integrated battery, which go into a socket on the board).
One has a Dallas DS12887, the other has a Houston HT12888A.
Following these genius instructions, I was able to "revive" the DS1287 in my 286. My next mini-project is doing the same to the DS12887 I have in the socket 7 board.
However, I have a problem...there is NO documentation for the Houston RTC modules out there, and they are not pin compatible.
I have found references to this information which DID once exist...but all links I find are now dead / go to holding pages. Someone, somewhere, knew how to do the same mod on the Houston chips, but the info is now gone.
I call out to you, Computing.Net, to please check through your old information and ask knowledgeable people you may know about this. The Houston chip is in a board I want to turn into a submerged PC (just for fun of course) but I want the CMOS settings to be able to be retained.
