Opening the Edirol CG-8 Case
The VIA EPIA-M Motherboard
The Edirol CG-8 uses a VIA EPIA M mini ITX PC motherboard produced in the early to mid-2000s. It uses the VIA CLE266 chipset and comes with 512Mb RAM in its single UDIMM memory slot and a 2.5in 40Gb hard drive, connected via IDE. The Retro Web provides comprehensive information about the board and notes that - like most computers of its age - it is prone to "faulty or leaking electrolytic capacitors".
RAM
The RAM chip is a single 512Mb DDR UDIMM PC2100. The board claims a maximum size of 1Gb, although I have yet to try more than 512Mb.
