OTZ80 - Remember it? :D

(1/5) > >>

alberthrocks:
Hey everyone! :D

So finally summer is here, and my school work has substantically decreased to nil! :) (Not that I have nothing else to do... like signing up for internships, studying for SAT, etc. :P)

OTZ80 will resume at full speed, assuming I (and others) can dedicate some time to working on it. This surprisingly comes at a time where recently we've discovered that TI have made a new boot code to block OS downgrades. (And believe me, you probably don't want to use their odd, horrific little 2.55MP :P)
OTARM, as you might know, will probably be shelved... for now. This is due to the fact that there's an Ubercalc being made with the
same exact goals as OTARM, and so we're likely to adopt UberCalc as OTARM's replacement. We also have some great OS (Linux distro) makers and some expert Linux users/devs at hand, so we will definitely be able to handle writing software/OS for it.

We are in a desperate need for HW experts! I'm hoping Ubercalc (the user, not the calculator) may be able to prototype an eZ80 calc for us! :) (If he's available at all, of course.)

Finally - there's some change in opinion about what CPU, what screen, etc. to use, so we may have a poll restart to regather opinion on it.

Here's to hoping we get enough progress this year to get a prototype out! :thumbsup:

Current feature list:
CPU: eZ80 50 MHZ, underclockable to 20 MHZ
Screen size: 192x128 (7 other people voted for 240x160, revote possible based on supply and opinion change)
Battery indication: On screen (part of OS)
Navigation: regular arrow keys
ASCII input: Alpha-lock
Backlit screen: Yes... 14 vs. 9 people on this topic, may need a revote to confirm.
I/O: 3.5 mm link cable and mini USB OTG
Power: Will definitely need a revote - this was the closest one ever, with no real winner. The top two were: AA battery (rechargeable if possible), and "#1 and 2" = internal rechargeable battery + AA battery (rechargeable if possible)

Omitted features:
Wifi (too much power munching, internet connection should be external)
SD card support (no use)

tloz128:
I'll do whatever I can to help. I'm not so great at assembly, and I could use a lot more experience with hardware, but I can do SOMETHING. (Maybe a battery indicator light or something.) :P

SirCmpwn:
Hooray!  I can still write the OS once I get hardware specs (extremely specific - port numbers and protocols).

Munchor:
Concerning OTZ80, the priority are the revotes in my opinion. Either way, nice to see this will have a new "wakening up"? :D

Yay, it got revived again!
