MESS TI cartridge requirements
From Ninerpedia
Cartridges from TI or third party had the following features:
Standard:
- 8 KiB ROM (address space 0x6000-0x7fff)
- 40 KiB GROM
Modules could have either one or both. Later consoles refused to mount modules without a GROM (trying to lock out third-party manufacturers).
Enhancements:
- 2 banks of 8 KiB ROM (e.g. Extended Basic)
- RAM
- MiniMemory (4 KiB)
- SuperCart/SuperSpace (4*8 KiB)
- MBX (1 KiB)
Special features:
- Parallel Port (word processor)
- Switches
- SuperModule (Wiesbaden): Reset, soft reset, select between ROM and loaded GK file
- GramKracker: 5 front-panel switches
- MultiCart: Selector
- Audio out (Forti system)
