processor
- 68060 @ 50 MHz
- can be ordered with empty CPU socket to put an existing 68060 into it
memory
- four 72 pin SIMM sockets accept 128 MB RAM
- supports 4, 8, 16, 32 MB SIMMs 60-70 ns
- 64 bit interleaved RAM access
- up to 68 MB/s transfer speed
- the Cyberstorm Mk3 is a bit picky about DRAM Chip Memory Array organization
- the card only has 11 address lines, thus only 2048×2048 organized DRAM Memory Arrays are supported
- 1024×4096 organized chips would need 12 address lines and are not working
- the Memory Array organization is given in the chip datasheet and not to be confused with the output bit configuration (e.g. 4M×4) of a DRAM chip
- if the chip has the wrong organization, only half of the RAM is recognised
notes
- the board is the same as the CyberStorm PPC without the PPC components - not upgradeable to PPC
- Ultra Wide SCSI controller, NCR 53C770 - supported by NetBSD
- expansion slot for the CyberVision PPC
- the SCSI controller needs the INT2 signal which is not present in the A3000's CPU slot
