Galaxian³ [Zolgear] Emulation : more boards pictures

[DarthNuno]

Your PCB photos helped a lot, especially the scaned picture, it's very clear. If possible, could you scan other boards, with their bottom sides as well?
Naibo

Hi Naibo,

What would be the most useful boards to scan for you? Both sides ? Or when you say the 'bottom" I presume you want to see the interconnect boards ?

Let me know... and thanks for your interest on this 

It's already amazing that you can 'browse" the objects 

Emulate a Galaxian3 ... the biggest challenge of this century 

[Naibo]

Hi, yes, I mean "both side" of these boards, so that I can trace circuit printed on the PCBs. I'm now studying CPU & DSP board. (does galaxian3 use the same DSP board as Starblade exactly,  or with some minor difference, such as ICs?)

I believe this "obj browser" can also work with Zolgear, if its ROMs are dumped. :-D

Let's start this once again.

On the rack n°2, there are three 'PERSONAL PCB' boards...all are the same! The scan of the components side is already done here.

Now here the 'printed circuits' side from the PERSONAL PCB board.

Too bad my A3 scanner can't do it (out of focus), so I'll use my old A4 AGFA scanner :



Two passes of course (board is bigger than A4) :



Note : there is a big overlap if you try to reassemble the two pictures 

Because it's a big work, can you tell me on which boards to work first ? Hope this can help

The scaned pictures are excellent. It helps a lot for tracing circuit.
I know that scanning these boards is a big work, let's start from master CPU & CRAM boards first, then each one of DSP, PGN & OBJ later...

Let me know if you want the 300 DPI version:

AWESOME Dexter  Thanks for your help on this 

Regarding the 300dpi version, it's up to Naibo of course.

I'll start to scan of the others boards asap.
