65816 Books

The race is on!  "Programming the 65816", by David Eyes from Prentice-Hall, originally scheduled for publication last October, is now expected in late April.  "65816/65802 Assembly Language Programming", by Michael Fischer from Osborne/McGraw- Hill, scheduled for May publication, is now also due in late April.  We have plenty of copies of these books on order, and a long list of patient people waiting for complete information on programming these powerful new chips.  Coming Soon...


More Memory Expansion

We'd like to call your attention to the new ad for Applied Engineering's RamFactor board.  This is a "Slinky" style memory expansion card for any standard slot of an Apple II, II+, or //e.  We've been doing some of the firmware for this product, and it's been a delight to work with.

One thing the ad doesn't really emphasize is the power and flexibility of the program switcher firmware.  You can set up the card with a variable number of variable-sized partitions and then switch between them almost instantly.  Any partition can be based on any operating system, or on your own program.  Couple this with the battery backup option (it's really more of an uninterruptible power suppply for the card) and you have what amounts to a hard disk operating at RAM speed!
