Has anyone (electronically inclined) considered using a ESP8266 or ESP32 to build a modern Wifi card for the Newton?
Both versions could also double as a Flash/SRAM card too !
Both provide:
-Ultra Low power operation
-on board processor(s) with RAM
   -ESP8266: single L106  @ 80MHz w/ 32KB & 32KB & 80KB & 16 KB RAM onboard (each has different purpose)
   -ESP32: Dual core LX6  @ 160/240MHz (600 DMIPS) w/520KB RAM)
-802.11 b/g/n
-Up to 16MB of QSPI external Flash
-Up to 4MB of QSPI external SRAM
-among other things…
The ESP32 adds many other niceties:
-Bluetooth 4.2
-Many Peripheral interfaces
-Ethernet MAC
-Cryptographic hardware acceleration
   -AES, SHA-2, RSA, elliptical curve, random number generator
-Flash or SRAM (via QSPI interface)
-(ESP32-D2WD) has 2MB of flash on board in addition to the QSPI interface for more externally
-and a lot more….
The ESP32 is about $10 individually.
It could also be used as a coprocessor!
This board could replace several PCMCIA cards and substantially reduce power.
This would be a really useful add-on for the Newton!
-Wifi with WEP2
-Wired Ethernet
-Flash or SRAM (via QSPI interface)
-and more in ONE card !!
What do you think?
Is there anyone willing to give this a go !?!
