A Whole Megabyte for your Apple //e........ Bob Sander-Cederlof

Both Applied Engineering and Saturn have announced 1 Mbyte cards for the //e.  Saturn's, I understand, plugs into any slot 1-7; this of course makes it a little non-standard compared to other //e memory expanders when it comes to software access.

The new board from Applied Engineering, called RAM WORKS, fits in the //e auxiliary slot.  You get 80 column text and double hi-res, with anywhere from 64K to 1 Megabyte of expansion RAM in 64K or 256K increments.  You can buy RAM WORKS already expanded, or expand it yourself later.  Prices:  64K = $179, 128K = $249, 256K = $449, 512K = $799, and 1Meg = $1499.  The first 512K fits one a normal size card, about 6 inches long.  The second 512K come in a piggy-back card which attaches to the main card.  Another option, an RGB video generator ($129), attaches to the front of the memory card.

The megabyte is divided into 16 chapters of 64K each.  You select which one is active by storing a value from $00 to $0F in a register at $C073.  Then the normal //e maze of soft switches lets you access the active chapter the same way you would access Apple's standard 64K card.

RAM WORKS has some new design ideas, for which patents are pending, including a power saving circuit and a video refresh circuit.  The latter eliminates the annoying screen flicker that normally occurs when you switch chapters with older expansion cards.

Low cost software options available with RAM WORKS include disk emulation for DOS and ProDOS, and workspace expansion for Appleworks.  Standard ProDOS will turn Apple's RAM card into a half-size RAMdisk, but with RAM WORKS you get a full megabyte!

If you like the idea of souping up your //e, one of these boards plus a new 65802 processor may be just the ticket!
