I didn't think too highly of his soldering of the DB9 connector and the LM317 regulator, he spends way too much time applying heat to the heat sink of the regulator overheating it. He left too much bare wire on the DB9 and he should have secured the db9 connector in vise grips or something to stop it from wobbling. Ok, mine is not perfect either but he uses too much heat. Practice makes perfect so they say :)Quote:

Yep count me in too for the group buys cpu, ram, sockets, Zorro connector, infact just about anything need.
I do have a question though .... the NTSC -11 Agnus you are discussing, does this need to be a pal version for those of us in Europe and if so is there one available ?
I'll buy from you Kipper2k just easier dealing with you since your in CAQuote:

I'm interested in getting in on the group buy of the harder to source parts , even some of the easier to get parts such as sockets etc.
Would also be interested in having the TSOP's soldered onto the boards as well.
I'm interested in a group buy for those parts..Quote:

I have contacted via George Brown. He confirmed that AGNUS 318069-11 (2MB NTSC) and 28.37516 MHz oscillator function in GBA1000 Rev.4!
did i mention i am ordering a few of each :)
And If I could get a TSOP done on my board.. you can add that to the price I owe you too. Thanks!
The 318069-11 (NTSC) will default to providing 60 Hz timing upon bootup.Quote:

Switching modes requires bit #5 of register $dff1dc being changed, so either a CPU/copper command must be issued to write the appropriate value (e.g as implemented by hitting the spacebar in the early bootup menu) or dedicated circuitry provided to emulate the command before system initialisation (unlikely to be implemented).
So, for a "PAL" machine the appropriate 28.37516 Mhz oscillator should be used and (preferably) matched with the 318069-10 Agnus, and for an "NTSC" machine the appropriate 28.6363 Mhz oscillator should be used and (preferably) matched with the 318069-11 Agnus.
Hi,
Count me also in or group buy of parts like cpu, ram, amber, connector... to make the all kit to solder.
yamakakiche.
Group buy for me too please.
thanks for clearing that up cheers.Quote:
