Maximum 71B Soft-Configured RAM Using FRAM71
Referring to the S/W IDS, Ch. 2 and 3
1. The memory available for soft-configured devices is the address range 30000-FFC00.
2. If a hard-coded module is installed, E0000-FFC00 will not be available for soft-configured devices.
1. Max RAM
The address range above provides 425472 bytes of RAM. Using 32 and 8K devices, 408K can be configured using the string "939495969798999A9B9C9D9EBF000000".
2. Max RAM with HP-IL
400K of memory can be utilized using the string "939495969798999A9B9C9DAE00000000".
384K of RAM is configured from 30000-EFFFF. Plug-In ROM's and IRAM's always begin configuration on a 32K boundary, so the HP-IL ROM is at F0000.
3. FORTH/Assembler ROM installed, no HP-IL
336K of memory can be utilized using the string "939495969798999A9BAC000000000000".
The high two pages of memory aren't available because of the hard-coded module. The FORTH ROM is configured at D0000. That leaves 320K for RAM.
4. FORTH/Assembler and HP-IL installed.
352K of memory can be utilized using the same config string as in 3., "939495969798999A9BAC000000000000".
320K is available for RAM.
I would appreciate it if someone would verify my findings.
