    I am just updating my thread here as I got it working. So what I did was just to solder 5V directly to pin3 on the cartridge connector on the docking and GND to pin1 on the cartridge conncetor. It powered up like a dream. So if anyone needs this mod -- it works :)

    Excellent. Thanks for the confirmation. I looked at the schematics for the TC but was unable to find the schematics for the docking V1 to find which pin was VCC and GND on the CN3 connector. You guys remember ?

    Hi. Cores, when flashed, have different types of naming and some are more cryptical than others. But I was wondering: is there, or can you make it, a way to rename a core after (or before) it is flashed so that I cam decide the name of it as to how it appears on the list of cores on the core launch menu ?

    For instance: I would very much like my cores to have a similar naming structure as opposed to what the developers decided at the time they were released :)

    Is this possible either via Chaco or possible to do before flashing it ? (Or maybe even after ?)



    Is it possible to power the Turbo Chameleon cartridge with 5V+GND from any of the pins on the PCB of the Docking ?

    For instance, are there any 5V pins on the Docking I can feed 5V (fom the usb charger) to power the unit instead of plugging it into the

    mini-usb connector on the side of the TC cartridge ?

    I am asking because I would like to build my TC and Docking into a case and would like less cables connected to the TC itself, and instead have a power

    conncetor feeding the Docking (which again powers the TC cartridge).

    If this is possible -- where on the Docking PCB can I hook up ?



    I use a Kingston 32GB SD card and I assume it's a bit old and slow cause my diskspeed feels a bit slow in Minimig. So I am gonna invest in a new SD card (also because my current SD card plastic case opened up accidentally.

    But - what is considered the best option here to get e.g. 32GB and the fastest IO ? Is it a samsung, a sandisk or a kingston ...or something else ?

    And what specs should I aim for. I want the best of the best and it has to be a MicroSD card (not fullsize) as I am gonna use it in an adapter.

    Suggestions, advises are welcome :)

    This fantastic Keyboard was sent to me from WASD Keyboards in California to review for use with retro hardware like the Turbo Chameleon since I needed a modern keyboard which worked both with USB and PS/2. So the guys over at WASD Keyboards flashed this keyb with a version of the firmware that support ps/2 protocol.

    The keyboard operaties incredibly well for the TC and I am also using it for productivity since it's also USB. I got it fancied up in Amiga colours and amiga modifier keys.

    I looked very long to decide if I wanted to use a old ps/2 keyboard for my TC experience or if I would be lucky to have a modern keyboard that supported ps/2 protocol as well, and

    I did find this at in the end. Took me months to source and contact vendors, then finally WASD confirmed their v2.5 firmware was ps/2 protocol compatible. So I want to share

    this with the community so anyone else can also buy it and not having to go thru all the loops which I had to by looksing and testing.

    Here is my review and summary. Hope it helps!

    Look here for the review: https://espenskogblog.wordpres…-keyboard-in-amiga-style/

    It's identical, except for a single line, the RTC select line. I didn't bother connecting that, as the Chameleon has it's own RTC. However, you pretty clearly asked for the possibility to connect a 4-way expander, and that's not possible, as these expanders require two more address lines that you can't get anywhere in the Chameleon - they are known only inside the FPGA.

    Ok, thanks for clearing that up for me. I just needed to know if an extender would work as it would open up for using more peripherals on the clockport_v1 core from Lallafa (or Alastair's new agacore if he find a way to include lallafa's clockportfix). :)

    There is no place where you could connect the additional two address lines that a 4-way clock port expander needs.

    Further, there is no driver for RR-Net on the Amiga, and I would not encourage anyone to write one, as it'll be dead slow and totally not Amiga-worthy without IRQs. The Amiga deserves better. I'm thinking of an adapter that lets you connect the X-Surf-500 between the Chameleon and the Docking station, but need to investigate if we have a sufficient amount of signal lines available.

    Yep. I think I asked about whether it would work on the amiga or not and that it would need a driver but it'd suck the life out of the cpu as it did not support interrupts (if I remember correctly) :) But -- I was mostly just asking electronically in my question above, whether or not the rrnet would still work with the c64core if it was connected via a clockport-extender. But you kind of answered that by informing me that the clockport lacked the extra addresslines.

    Is the clockport on the tc64 not quite alike the clockport on the a1200 pinout-wise ?

    The fully-featured 68000/'020 switchable TG68 takes up around 7,000 logic elements (and uses 2 memory blocks).

    With the '020 stuff disabled to make it a smaller microcontroller it takes up around 4,400 (still using 2 memory blocks).

    My own core, EightThirtyTwo, uses around 1,400 (and no memory blocks) in its smallest configuration as used in the new Minimig core. (This rises to around 2,200 if you enable interrupts, partial result forwarding and dual threads.)

    Nice, so you've freed up about 5600 elements (gates?) in the best case scenario ? That is supernice -- was that the thing which made able to fit a full aga-core ? Out of curiosity, how much free elements are left currently with the current agacore ?

    Jens - we've soon passed 800 members in the TC64 Facebook Group so if you need to spread some info to a large crowd to current and possibly future TC-customers -- just let us know and I'll put it up there. I am the creator of the group and we'd gladly help to spread news and updates there as well.
