A92: EII feature list
I'm happy to announce the EII. If you would like to reserve a
firmware chip for the EII, please send me an e-mail. I currently only have
16 to sell. The chips won't be available immediately, but in a day or two,
so you don't have to get out your money yet. If you have a TI-92 you
should be very interested in this. If you have a TI-85, you should wait
for a bug free driver to be released.
The EII memory expander has these features:
-8bit I/O
The 8bit I/O can be used to interface with many different devices.
There is already devolpement in "ti-hardware" for 8 bit sound capibilities.
Other possibilities being worked on are 5 1/4 and 3 1/2 disk drives,
serial UART, Parallel printer, Character LCD, IDE hard drives, remote
control, the possibilities are endless!
-256, 512, 1, and 2MB capacities
The EII will interface with 256k, 512k, 1MB, and 2MB chips without
midification to the hardware. This allows you to have an inexpensive
cartridge ($8) for games, or allows you to have a more expensive ($20) 2MB
cartridge for pictures.
-Removable cartridges
The EII will support cartridges with all the capacities listed
above. You can exchange a cartridge with another person just by pulling it
out! The EII even has protection built in. If you take a cartridge out
before turning off the EII, it will automatically turn off!
-Status light
The EII has a LED that operates like the busy light on your modem
or hard drive. When the EII's memory is being accessed, it will turn on
for the length of the transfer.
-Memory life
The memory used in the EII is top of the line FLASH. It takes over
1,000,000 writes to burn a $10 chip out. People have tried doing this, and
after a few million times, gave up. 1 million is just the minimum! The
EII will retain the memroy in the cartridges for over 10 years also.
-Compatibility
The EII is currently compatible with the TI-92, and by the time its
released, a beta version of the TI-85 driver will have been released.
There are problems with ASH and CrASH so a TI-82 driver is impossible. A
TI-86 driver is on the way also! The TI-83 will either be supported after
the 86, or in the EIII when its announced in 2 weeks.
If you have questions/comments please send them to gussie@alaska.net.
Thanks,
Grant
