PROM-Based RMX/SO BASIC-SO

Configuring PROM-Based RMX/80 BASIC-80 With or Without DFS. If you do not need DFS facilities, PROM requirements are reduced by 7K bytes and RAM requirements are reduced by 1.6K bytes. You can configure without DFS by:

I.Setting DFS to 0 in BQOPS.ASM before assembling BASCM.ASM and BQMEM.ASM.

2.Excluding the DFS libraries from GBASIC.CSD, as in figure F-S.The DFS modules RQRNMX, RQDELX, RQOPNX, and RQATRX will be unresolved externals, but they present no difficulties.

Configuring a PROM-Based BASIC-SO For An iSBC 80/10-A Based System. In a typical iSBC SO/IO-A configuration, the memory allocation would look like this (refer to the iSBC 80/10 and iSBC 80/10A Hardware Reference Manual.

On board PROM:	OK to 8K
On board RAM:	15K to 16K
iSBC 016 RAM:	16K to 32K
iSBC 464:	32K to 57K

System PROM is discontiguous, making linking and locating the configuration module more difficult. Follow these steps:

I.Edit the BQOPS .ASM module to specify the desired options. A sample iSBC SO/IO module is listed below.

CPU	SET	10	;MODEL OF CPU
BOOTED	SET	o	;1 IF BOOT VERSION, ELSE 0
TERMH	SET	o	;1 FOR FULL TH, 0 FOR MINI
RATE	SET	7	;BAUD RATE FACTOR
CONTR	SET	204	;CONTROLLER NUMBER
DFS	SET	6	;NUMBER OF DFS FILES OPEN AT ONCE
UIO	SET	o	;1 IF USER I/O DRIVERS ELSE 0
NFILES	SET	6	;TOTAL FILES
HIRAM	SET	07FFFH	;HIGHEST RAM LOCATION
BOTMEM	SET	OH	;BOTTOM OF BOOT LOADER RAM
