Components

• Opti 495SLC motherboard/chipset with 5 ISA and 2 VLB slots
• Intel 486DX50 CPU
• OPTI-495SLC BIOS VER 2.1A (although the chip says AMI 386C Bios)

I want to make the changes:

• The battery has been removed. I want to add a new battery.
• maybe add more or faster memory.
• add a solid state storage solution.
• add a sound card.
• add a VLB graphics card.
• add a Gotek floppy drive.
• maybe add a 5,25 inch floppy drive.
• add a nice case badge.
• add a mouse (maybe through a serial to PS/2 adapter).
• get a 5-pin DIN to PS/2 connector for a better keyboard.
• get some blank PCI brackets to cover the empty holes.
• get a more silent PSU.
• maybe add a PCMIDI card.
