No pics because in my stupid, stupid youth I did a terrible paint job I'm not proud to show and am only slightly less ashamed to admit. Luckily I left most of the stickers intact though. I'll sand it down and respray once college gives me some of my precious time back... maybe Thanksgiving in a couple weeks...

 

Interesting, I'd like to get a schematic for that buffer / terminator (dummy) board listed.

Too bad there arn't any markings on the 50 pin connector itself.

 

Some people say rev. 0 Dreamcasts dont come with a modem. Is that true? Mine is a 670-13748E model (produced in 1999) with the metal fan and a modem. It came in one of those orange boxes with Yukawa's photo. That plastic triangle on top of it is translucid.It's second hand. I'd like to know if its rev. 0 or not...

 

Asian VA0 Dreacast units did indeed come with a terminator board instead of a modem. Japanese units came with a 33K modem and a copy of the 1st Dream passport. I happen to have two copies of the Dream Passport disc. 1.00 and 1.01...

The VA0 Dreamcast I used to play PSO was an JP VA0 UGO Denshi model.

 

Here's one that was a bit strange, so I picked it up from Europe second hand.
No modem on this one either. Just a piece of modem shaped plastic.Full photo gallery here. Enjoy!

Interesting ! I remember seeing this one on ebay.
So it is an undumped bios. What are differences against 1.01d version (89f2b1a1) ?

 

Oh the differences... Apparently a typo was fixed
Here's where it all panned out, if you are up for a bit of reading.

 

Just pulled apart my USA BBA that I picked up recently, looks to be very similar to the Japanese one on the website. Only difference appears to be the revision (171-8124D vs 171-8124F). Datestamp of 0024 on the 315-6310 and 0021 on the Pulse H0011.
