Amiga Processor Peripherals


CyberStorm MK3

> Company: Pahse 5 Digital Products, Germany
Date: 1998
Amiga: 3000, 4000
Interface: CPU slot
Autoconfig ID: 8512/100

Processor
68060 @ 50 MHz
It 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
