ISA Bridges |
||
 |
 |
I guess this is the first revision of an Zorro<->ISA Bridge This was long long before my time at VT |
 |
 |
Its 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 its a fully populated production card with a little addon DAC, that allows to display full 16.8 Million colors with a Domino not just 32k |
|
PII |
||
 |
 |
the upper card has a little badge on the graphic 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 Ariandne(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 as an PII version for the A500(+) I've been told that it actually never worked |
|
Ariadne 1 |
|
 |
 |
 |
 |
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, its was created for the planned PicassoIII which never saw the light of day, since the planned oak spitfire
finally had a shortcoming which I don't remember 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, this one should have been used for the 3D Module development, which was never finished, one could fit a Mac 3D Overdrive into the backplane and connect it to a paloma for the pixel capturing into the Cirrus framebuffer |
 |
 |
prototype of the work-a-like DAC that does all the magic for the 3D Overdrive |
