calypso

Plus Calypso is one of the only baseband processors out there that accepts unsigned firmware (which is exactly why it's OsmocomBB's target) and 3G on Calypso is not possible.

Suddenly Neo Freerunner became free again because there's a free firmware available for Calypso now.

They can be easily intercepted by anyone near your phone with TI Calypso based phone, like Openmoko Neo Freerunner or old Motorola phones.

I ran calypso.z3, tristam_island.z3 and a few more Zmachine text adventures under an interpreter created in PostScript.

Enjoy your steel-drum calypso music while you barbecue on your steel-drum smoker.

I was a part of Openmoko community in the past and remember the TI Calypso modem used inside Neo1973 and Neo Freerunner.

[1] With the very tiny exceptions of calypso-based motorola phones running osmocom and possibly the neo freerunner phones...

That would give us a new, modern equivalent to the calypso baseband which is open and hackable, and is the de facto standard for osmocombb running on handsets.

I think in cases where it' a major rebuild, like turning a WW2 Minesweeper first into a ferry, and finally into Cousteau's research ship Calypso this outlook is more obvious.

He's been at it for three and a half years and is almost through "Calypso", the fourth chapter.

A modern, LTE capable "calypso" would be a game changer.

> “The models are getting better, but they’re also more likely to be good at bad stuff,” said James White, chief technology officer at cybersecurity startup Calypso.

All other modems are locked with crypto keys (TI Calypso also had this ability, but for some strange reason it went out of factory with security checks disabled - that's why its the only modem OsmocomBB works on) From Neo900 project there are plans to support "special orders" from people who want to mount TI Calypso on their PCB instead of standard modem.

Before mobile era there was incredible mail <s>app</s> programme - Calypso.

You can't use non-certified firmware for modems, like OsmocomBB for TI Calypso, on public networks (yes, there is even free software GSM modem firmware!), but GSM stacks in user space are possible and legal.

PostSscript files came from the same company in the 80's -Adobe- and with GhostScript and zmachine.ps you can play Zork I-III, Calypso, Tristam Island and the rest of propietary Infocom text adventures on it with ease.
