So, my quest for a portable PC led me to this:
It's an Ocean Systems machine, but I figure it's just a rebranded ACME TAP-763. It has a 15 inch 1024x768 screen, a mechanical keyboard with a built-in touchpad, a built-in A/V converter for VGA. The bottom line — it can take any standard ATX motherboard, a standard PSU and any videocard with VGA output. It also weighs 12 KG (just the chassis, screen and keyboards)
The machine originally had an AMD Phenom inside, so I'm pretty sure the original hardware was long gone. Right now I've installed an Intel SE440BX-2 with a Pentium 3/1GHz, a Voodoo 5 and some ISA soundcards. This is going to be my box for LAN parties, so I'm pretty sure I'm going to switch to a Tualatin-based system with GeForce 3/4, but for now it just amuses me that a pretty much "ultimate" DOS/Win9x machine can be lugged around.
There are some issues, though. The case smells like cat piss (it was stored in a garage for a while), so I foolishly rubbed the whole chassis with IPA. That nearly destroyed the rubber coating on the keyboard. Another issue is that the locking mechanism on the keyboard is semi broken. Does anyone know where I could get a replacement keyboard for a TAP-763? 😀
Also there is a dead pixel on the LCD, the power LED connector was modified from 3-pin to 2-pin and there are some cracks and broken screw holes. I'll do a dedicated post with lots of photos once I do some work on the system.
