Hi! I've just got (for free :) an ancient MIPS ACER PICA 61 motherboard. Can anyone help/guide me to run Linux-MIPS on this machine ? Is it still possible to run Linux on this architecture ? The motherboard is old (~1993) and it is very difficult to find any documentations... AFAIK, this is version of ARC MIPS. (mipsel) This is Full-size AT board, AT power supply, 5 ISA slots, 8 SIMM slots. The CPU is PACEMIPS R4000-50Mhz (x2=100 internal ???) by Performance Semiconductor Corp.. NatSemi Ethernet/AUI onboard. No IDE connector. One additional slot is not ISA, but maked as IO an contains SCSI/Floppy/Serial/Perallel/Mice card. Another slot is like reversed EISA (double) and marked as VIO (locabus video?). Unfortunately, the original videocard is lost. :( However it works fine with old CirrusLogic VGA card in ISA slot (old ISA Trident 8900/9000 does not works). St.Petersburg, Russia -- -=AV=-
