VT Prototype Shrine A collection of VT prototype hardware the whole bunch ISA Bridges I guess this is the first revision of an Zorro-ISA Bridge. This was long long before my time at VT. An ISA bridge with two VGA connectors, possibly for the Domino, since there are no relays on the card. Domino Different revisions of Dominos. This one is special: a fully populated production card with a little add-on DAC that allows display of full 16.8 million colors with a Domino, not just 32k. PII The upper card has a little badge on the graphics chip stating "Cloanto" — it means the card was once given to them for their software developments. The lower "card" is a papered version of an Ariadne (I) to check the design fitting. This one is special in that it was fitted with some newer relays to try out for a newer design revision. Picasso Classic This one never made it into production. It was thought of as a PII version for the A500(+). I've been told it actually never worked. Ariadne I MultiIO This card was also never produced nor made it to a working state. Harald Frank of vmc was involved in the development, I guess for the software. The card was to provide fast serial and parallel IO and also PC-compatible floppy IO for cheapish PC floppy tape streamers. PIV Left: the first PCI Bridge prototype still with two big AMD MACH PLDs. It was created for the planned Picasso III which never saw the light of day. Right: handmade proto of the Denise adapter for the PIV. The second PCI Bridge proto for the PIV, this time already with the later used XC5210 Xilinx FPGA, but the 160-pin version. PCI adapter for the PIV, meant for the never-finished 3D Module development. One could fit a Mac 3D Overdrive into the backplane and connect it to a Paloma for pixel capture into the Cirrus framebuffer. Prototype of the work-alike DAC that does all the magic for the 3D Overdrive. VT Prototype Shrine
