    Even the powerup sound of the AtariVox seems off to me.

    That's my British pronunciation :cool:

     

    BTW the start-up can be changed. I can instruct you how to do it if you want ?

     

     

    I had always wished I had an Alien Voice Box because that thing supposedly could sing.

    AVox can sing too.

     

     

     

    Wouldn't it be cool if someone used the TTS algorithm in a game.

    OK, then serial mode only for the SpeakJet seems the best way to go. So from that POV, the support I'm adding to Stella will work with any serial converter, not the the AVox USB one.

    That's right :cool:

     

    Just been doing a bit of coding and I have managed to read / write the CBUS pins (using the D2XX DLL). So it should just be a matter of incorporating the i2c protocol for me to get access to the EEPROM.

    now that I think of it, how did the old serial port adaptor access the EEPROM stuff? Because maybe it can be done through the serial port??

    The old serial adaptor used a microcontroller attached to the EEPROM and a separate utility to access it (via serial at a lower baud rate). The new one has the EEPROM connected directly to two of the FT232R's i/o ports (and can't be accessed through the VCP).

     

    IMHO it would definitely be best to simulate the EEPROM in Stella as multiple writes (e.g. during testing) to the actual chip would eventually wear it out.

     

    I'll try and write a separate utility for accessing the EEPROM, perhaps just a simple backup or something.

    Chris has pretty much covered your answers. The FTDI site has everything you need, VCP (Virtual Com Port) and direct i/o control drivers (D2XX) of the chip (for accessing the EEPROM). BTW the AVox (and SaveKey) EEPROM SCL is connected to CBUS0, and SDA to CBUS1. The i2c protocol is documented in the driver code.

     

    The AVox speech / sound works on 19200 baud 8n1 serial. It's actually inverted, but that's done through an option in the FTDI chip's firmware.

     

    I can send you an interface, but I don't have any AVox's here as they're all built by Albert now. Perhaps he could loan you one or something.

    If Stephen Anthony (or who ever) wants to put support into Stella, I'll gladly send them a complimentary interface. Don't forget it can be made to work with the AVox's EEPROM memory (and SaveKey) too, there's some programming docs on the FTDI site to access the chip ports (which are already connected to the memory).

    Everything is minty new looking however aside from the dead pens. I might try the alcohol pen trick to see if that works when time permits.

    Looks like the same printer innards as my CBM 1520. I got my pens going by gently heating them with a hairdrier and then dipping the tips in hot water for a few seconds.

     

    BTW does anyone know if replacements can still be purchased ?

    Nice review :lol:

     

     

    I guess I was just referring to the "raspberry" sound effect

    That's one of the pre-set sounds. You can get some good effects when used with the volume, pitch, speed and bend settings.

     

    I remember John saying a while back that using the music synth takes a lot of resources on the 2600. This shouldn't be problem when used on the Chimera's serial port.

     

    The synth has quite a nice 50's Sci Fi quality to it.

    Nathan, I can send you a USB interface, it works with PhraseALator and will make your task a LOT easier / quicker.

     

    BTW when I'm making new words, I start with the standard dictionary and tweak / copy until I have something which sounds right. It's pretty easy, and once you have your custom library it's then just a case of inserting the codes into your program.
