Thanks for the Kickstart switcher! I've installed this in my NTSC A1000 yesterday, along with a TF536. It's a tight fit but it works great!
There are products for USB to Amiga keyboard adapters, e.g. "Sum A234/CD32". Unfortunately the A1000 has a different connector, but I think the electronics are the same.
I don't see why it should not work with the Rejuvenator.
That is experimental. I want to use one of the QMTECH FPGA boards which you can find on AliExpress as a base, e.g. the QMTECH Intel Cyclone IV EP4CE55. I haven't started with the VHDL code, but the schematic and layout of the base board should be finished although not tested, yet.intric8 wrote: ↑Wed Nov 11, 2020 6:33 pmSpeaking just for me, since I have neither a TF or Vampire, can you explain a little bit more about the "FPGA socket to use an FPGA as a CPU emulation"? That sounds very interesting. You might should consider making this board its own thread whenever your boards arrive. (Or, I think I can help with that now if you like.)
At the moment I placed 5 jumpers and one of them disables the Kick Flash at 0xF80000, but it leaves the range at 0xE00000 active to be able to do the flash programming while the active Kickstart runs from internal WOM/ROM. It is also needed, because the flash will be empty when it is delivered or probably flashed with the DiagROM.
There are no buffers at the Zorro I bus (in contrast to Zorro II), so the load to the bus lines could become too high when too many cards are chained, but two should probably work.intric8 wrote: ↑Wed Nov 11, 2020 6:33 pmAs an A1K fan that uses his expansion port today, my only concern would be if I could continue to use my Microbotics 2MB RAM that I also use for its SCSI port. That's how I boot via "hdd." I wonder if I could stick this board out of the Microbotics side port? Oh man that would look nuts, but it would be an interesting experiment for sure.
I don't have an A1000 myself, that's why I additionally need an A500 connector for testing. So I have no experience with such problems.intric8 wrote: ↑Wed Nov 11, 2020 6:33 pmNot sure about you guys, but the expansion ports on some of my A1Ks can be a bit finicky at times if the connection isn't spot on. Sometimes how an expansion "hangs" on the outside can have a dramatic effect on it working, even if the angle change is a fraction of a millimeter.
I use an ATF22V10C and the /OVR signal to disable the internal Kickstart. To switch between the two Kickstarts in the flash I just use a jumper where a switch can be connected.
