Re: TI-H: TI-85 disk drive
It woudl go at about 1200bps... :) Thats about 7x slower than a standard
link. The EII (mels model) will transfer at speeds reaching 5k and
transfer backups at 1.2k...
I've decided to do what mel was going to do orrigionally... Out of the
hundreds of people that e-mailed me, bakckups were important...
Orrigionally, there will only be support for 85 backups...
I think that I've finally have a good pdf file <g> I will start the
communication routines... Other than that, I can use the existing code
from my serial port driver... Then you can have a modem attached to your
calculator and use EII memory! :)
I think you may be able to get an EII by sunday...
I'm starting a new campaign... If I receive 40 different e-mails from 40
different people then I'll start on it tomorow instead of friday... ;)
not jokeing... :|
