Alright, thanks to bj74cruiser, I now have a mega pc. In short, it's a 386 computer & sega megadrive in one. Now, I thought that due to lack of photos on the rest of the internets, I'll upload some internal pictures here. You can search for external photos, I currently have it apart. Yea, I havn't even powered it on yet, I pulled it apart instead. I tend to do that. http://i96.photobucket.com/albums/l186/mv75/Image0124.jpg Motherboard picture. FINALLY! Someone has posted a picture of the actual motherboard. About frigging time they just stopped showing their megapcs off and actually showed something useful I say. http://i96.photobucket.com/albums/l186/mv75/Image0127.jpg Bottom left, video card area. Looks to be some sort of WD 90c paradise card, 2x memory chips with 2x 4464 empty sockets with "vga memory expansion" screen printed on. If someone has more patience than me to find actual datasheets, the chips on there are aaa1m304p-08 I guess they are 64kx8 80ns chips giving 512KB for 4 of them. I have quite a few spares of these chips to plug in. To the top right is a vga disable jumper. Yea, I'm going to try that and plug another vga card in instead. Well, maybe. To the bottom left, the pin row is where the ribbon cable from the megapc card plugs in. To the bottom right is a 3 bank of jumpers labelled 16color, 256color and non-int. Now this one is interesting, the 16color and the non interlaced ones are jumpered, the 256color one is open. Maybe it'll affect the mega drive output? http://i96.photobucket.com/albums/l186/mv75/Image0128.jpg Ram slots. Interesting is the empty solder joints for 4 more sockets. If I had the actual sockets, I'd try and solder 4 more on. Anyone got leads for those? Oh yea, Co-processor socket too. Anyone got a spare? http://i96.photobucket.com/albums/l186/mv75/Image0130.jpg Megapc card itself. Yes, 8 bit. For power only I think the edge connector is. This one is interesting, it appears to have that red "do not remove" thing over an edge connecter just like the megadrive2 IIRC, has internally. I forget what it's for, anyone elaborate? Ok, on the left, it seems that side is a sound card. It has a yamaha chip. The big rectangle is a z80 cpu. The middle is a "sega" chip and the right is a motorola 68k. The long black strip is a sort of edge connector that plugs into the front interface card. http://i96.photobucket.com/albums/l186/mv75/Image0131.jpg "inner" of the front interface card. That is where the megadrive card plugs in. http://i96.photobucket.com/albums/l186/mv75/Image0132.jpg "Outer" side. Joystick ports, cartridge port, reset button, mega/pc select switch and a volume slider. There is also a microswitch above the cart port, dunno what it's for, it's depressed when installed. EDIT: I just figured it out, when a cart is installed it would depress that. I guess that is the "power" switch for the megadrive side. Oh yea, the hole in the card is where the red edge connector on the megadrive isa card slots through. On the front of the computer where it says megadrive compatible, or whatever, that panel is removable and has that covered edge connector behind it. Anyway, ask more questions while anyone wants to as I'll have the board out for a little while longer as I'll re-replace the battery as, sorry bj74cruiser, but it was a pretty crap solder job that I'll re-do properly. Oh yea, the size of the machine is pretty small too. Only about another ~3 inches more from the top of the motherboard. Quite a small computer. Maybe about the size of a matx machine, but slimline.
