Tearing into ProDOS

Have we got a treat for you!  You've heard about ProDOS, the new operating system for the Apple II's.  Its main advantage over DOS 3.3 is speed, and on the next page of this issue you'll start to see what makes it so fast.  ProDOS uses a completely different technique for translating between memory bytes and nibble-coded disk data, and here it is!  Start reading Bob's completely commented disassembly.


Holiday Special Prices

Remember that we are offering special prices on several popular products from our list.  Check the ad on page two for details.  We are also having a sale on back issues of Apple Assembly Line: now only $1.00 each, rather than the usual $1.50.  This is the time to complete your set!  Subscription rates will be going up as of the first of the year, but you can still renew at the current prices.  Let us hear from you.


Non-volatile RAM

Rodney Jacks, a Mostek engineer, tells us of a very interesting new chip:  a 2K-byte static RAM, plug compatible with a 2716 EPROM, with a built-in lithium battery.  Call your distributor and ask for Mostek MK48Z02.  I can hardly wait to get some.
