GM>A perenial problem. Believe me, it gets worse as you get older!

GM>Now here's a puzzler that you or one of our other correspondents may be able to
GM>help with.

GM>I have been given an EPSON 386 computer, model EL3/33. The problem with it is
GM>that the CMOS battery has died. But I can't find anything that looks like a
GM>battery anywhere on board.

GM>I even opened the p/s to check for a battery inside, but no go there too.

GM>But there is a realtime clock module - "DALLAS DS1287 REAL TIME
9026B3".

That IS the clock AND the battery!! Go hereto learn more:

GM>Does anyone recognize this part? Is it one of those clock modules with the
GM>internal battery? If so is there anyway to bypass the battery or hook in an
GM>external one?

GM>I'd hate to scrap the computer, as it would be dandy as a second (or third)
GM>unit for multitasking while my main one is busy.

GM>But as the m'board is VERY nonstandard, as are all the other boards and the
GM>p/s, if it can't be repaired I'll grab the FDD and HDD and scrap the rest.

GM>Written in haste, online, after being locked out of the BBS for several days.

GM>Greg
