I've ordered some PCB but they are already asking me questions about how to do certain things which has me a bit worried.

If someone made an A600 case with the expansion port removed and just a flat base I reckon it would be pretty easy, all you'd really need to modify is the joystick area and any expansion card would have to be really short, or maybe just remove the edge connector altogether and add some fast ram in the empty space. I've been interested to know how the Blizzard 1220/4 doubles the 14mhz clock actually.
Trying to design a board around the stock A600 case is going to be really difficult though, definitely more trouble than it's worth. |

Tentatively this should be possible as I think the CD32 would close to fitting inside an A600 case if you exclude the optical drive. That would pretty much become an A1200 equivalent if you equip it with something like a TF328/330/360

I liked the form factor, but as a machine A600 seriously underperformed, but if at its core it had AA it could be a nice machine and quite portable!

I think I've found a good substitute for the line filter.
KEMET SHO-301 What do you guys reckon? |

Boards have arrived just give me about 3 months to build one. I've done it as accurate as possible the only real difference is I smoothed out the grounds fills as they were all over the place. The software Commodore used for fills did some weird stuff.

I've managed to get hold of a CD32 relatively cheaply if I were to buy some rev 4.1 boards with hard gold connector and assuming it works (it will) would anyone be interested in buying a board so that I can make some money back? it costs at least £500 for 30U hard gold so it's quite a big investment. If you use a Rohm BH7236 RGB encoder all of the signals are present for the RGB connector without need for the Band Pass Filter or Delay Line, it's just missing the audio buffer used for the RF modulator.

Also sorry for being slow getting stuff done and presumably coming across like a tease but these have more or less been hobby projects and when it comes to actually buying PCB's I get scared because of how costly it can be (particularly with mistakes etc). I've sold two A3660's (with full 060's) and a bunch of other stuff over the last year to raise some money to try and make something happen.
