If anyone of you is interested in helping me complete the software please contact me. I could provide a prototype for those of you who can make me believe they are seriously interested.
The finished projects could either be published as "Freeware" (instructions, diagrams + software) or sold as products (or even both).
|Project||Platform||Status Hardware||Status Software||Price of components (DM)||Difficulty||Description|
|4-Slot Backplane||A3XX, A4XX||finished, untested||not needed||20,-||medium||Double sided PCB, soldering the connectors is difficult|
|Sound Sampler Podule||Archimedes, RiscPC||finished, tested;
could be optimized
Patch for !Armadeus
|50,-||low/medium||8-Bit A/D-Converter, 100kHz
Simple double-sided PCB with only a few components
|SCSI-Hostadapter Podule||Archimedes, RiscPC||finished, tested||finished and tested on Archimedes,
but very poor performance
|80,-||mittel||Passive 8-Bit hostadapter built around an NCR 5380, double-sided PCB.
Drivers are finished and were in use for almost two years without any problems. Performance is very poor (around 100KB/s). New drivers could overcome this problem and give about 1.2MB/s
|I/O Expansion Podule||Archimedes, RiscPC||finished, tested||started||20,-||low||double sided PCB, 16 bit input, 16 bit output, TTL|
|Floating Point Coprozessor Podule||Archimedes, RiscPC||finished, tested||started||150,-||medium||Floating point accelerator based on MC 68882
Two prototypes have been built and gice an estimated speed increase of factor 20 on Archimedes (ARM3) and factor 5 on RiscPC (StrongARM). However, the Acorn FPA is still faster. The 68882 is expensive (100,-/33MHz) and not very common.
