Description

Memory

The on-board memory occupies a contiguous 32-Kbyte address space, the
base being at C8000h or D0000h (jumper selectable). All memory is 8-
bit only. The following table shows the memory map:

The BIOS is a 12V non-sectored Flash device. Since it is not critical to
the system boot process, no jumper mechanism is present to enable an
alternative ‘boot’ block.

The Flash disk is a 2-Mbyte 12V part. Since the part requires a tight-
toleranced 12V rail, a DC/DC converter generates the programming
voltage. The part is protected from programming via an Apricot port.

The 32-Kbyte SRAM is for use by the BIOS as a stack or for other
storage purposes.

On card reset, the SRAM and DOS Flash are disabled, being enabled by
the BIOS through the Apricot Control Register.
