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 |
Module started 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. |
