Do you like this my MD2 ?

I found a handful of VFD tubes when I was stashing through my pile of electronics and then I thought that I'd put them into my MD2 for extra coolness
After a day of operation these get pretty warm (and associated resistors really hot), but I guess it isn't fatal. These work on 12V, pretty scary as there's 5V everywhere else...

HAHA lol
I already thought in that but my idea was to put a rectangular VFD from a recorder
It has 2 big digits in the top, then 4 digits at it's right and 5 digits at the bottom, it was perfect for address bus at the top and data bus at the bottom
but it needes heavy decoding
Are you decoding or just conecting the segments to random lines?

I think it's just hardwired to display Sega (or as close as you can come on such a display anyway).
My Genesis has a minor modification which allows me to disconnect the /CART_IN signal (useful for dumping), but my wiring came undone so I need to make some repairs. I currently can't play cartridge games as a result.

Yeah I didn't noticed the "SEGA", I saw it as a 5E6A hexadecimal number...

5E6A is SEGA... and everything is hardwired, I already got too little room in it !!! I'm thinking of adding "internal" game in it too, like in SMS or some new more kick-ass famicom clones... I wonder if I could fit 2 flash chips between the board(underside) and RF shield... everything else fits, I want to continue this...
Show me YOUR mods

Pretty cool design, got no Genny so I haven't been able to mod one.

A tssop package flash fits very good between underside board and the shield

But I need to make a PCB then... I hate making PCBs for any kind of TSOP packages... wait a little... I have some PLCCs... 512KB is enough for Sonic 1...
