No Slot Clock, Arrived and Works

Today the chip came in.  It is a Dallas DS1216E  I purchased it on eBay for $6.50 with $4.00 for shipping and it took about nine days to arrive in a box slightly larger than a deck of playing cards.

DON’T TRY THIS AT HOME  IF YOU DO TRY IT, YOU DO SO AT YOUR OWN RISK.  That being said here is what I have done to test the No Slot Clock.

Not having opened my //c before I did some quick research.  I found a copy of the No Slot Clock Apple //c Install Instructions on Apple2Online.  Unfortunately, while they show where to put the chip they don’t show how to take the //c apart.

Further research found Apple //c V4 ROM Upgrade Installation.  This book has pictures that show which screws to undo, which is important because there are ten screws.  The book shows the six screws to remove.  Removing the screws didn’t let the case open, the book refers you to another document, which I couldn’t find.

I did find a web page at ifixit.com which has step by step guides.  They have one on opening the Apple //c, which I provide the link for.  Basically you remove the six screws and push in on the front seam to release a hidden catch and push the top part of the case back and off.

Once the case was open, I just lifted the keyboard back over the disk drive and followed the directions for the No Slot Clock, mentioned above.

When I got the //c put together I booted it up with a disk that had the no slot clock driver on it.  After ProDos loaded, so did the No Slot Clock driver.

I downloaded a copy of the No Slot Clock Utilities 1.4, again from Apple2Online, using ADTPro.  When I Booted it up on the //c,  the Applesoft Startup program crashed with a dimension error.  I ran the ns.clock.utils program with the dash and set the date and time.  Once the date and time were set the startup program runs fine.

I was able to read the date and time using both Applesoft and ZBasic.
