; Memory map for 128K memory configuration:
;
;	    -27ff	Free
;	2800-2fff	AMSDOS read buffer
;	3000-37ff	AMSDOS write buffer
;	3800-7cff	Code
;	7d00-7dff	Buffer for keyboard input
;	7e00-7eff	Reserved for mode 2 text accelerator
;	7f00-7fff	Reserved for screen blanker
;	8000-83ff	Buffer for IP datagram (rx, and tx response)
;	8400-87ff	Buffer for IP datagram (timeout/async tx)
;	8800-8fff	Special code
;	9000-		Free
;
;	Bank 4		RX serial buffer
;	Bank 5		TX serial buffer
;	Bank 6		Loopback buffer
;	Bank 7		Free
;
; Note it's all a bit of a juggling act.
;
; In the 128K memory configuration, the serial device driver and
; loopback driver can't be in bank 1 because they switch this out,
; so they have to be below &4000 or above &7fff.
;
; The components which use events, however, can't be in bank 0
; because event blocks must be in the central 32K, so have to be above &3fff!
;
; A polled serial device driver, which needs to do both,
; therefore has to be placed in a special area in bank 2.
;
; It's a bit simpler in the 64K memory configuration; the only concern here
; is the one about components using events not being in bank 0.
;
; The memory map for the 64K memory configuration changes as follows:
;
;	8800-8bff	TX serial buffer
;	8c00-8fff	RX serial buffer
;	9000-93ff	Loopback buffer
;	9400-		Free
