Max 71B Memory Using FRAM71
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". Code: Port Dev Size Addr Type 2. Max RAM with HP-IL 400K of memory can be utilized using the string "939495969798999A9B9C9DAE00000000". Code: Port Dev Size Addr Type 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". Code: Port Dev Size Addr Type 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". Code: Port Dev Size Addr Type 320K is available for RAM. I would appreciate it if someone would verify my findings. Dave |
