I recently un-mothballed my old HYDRA games platform, and (sob!) discovered that it was no longer fully functional. The HYDRA was my first Propeller 1 system, and I not only have very fond memories of it, I still have lots of hardware accessories and software written specifically for it.
The original HYDRA now seems to be unavailable anywhere, but if anyone has one in working order that they no longer want, I would be happy to buy it.
Name your price!
