Package arrived from the US this morning which I assume to be the LSI chip (I'm not expecting anything else from the US). I'll get it programmed up in the next day or two and get it on it's way back by the end of the week.
Yeah, true! But if i can count on you later, that would really be great.
Sure! I would like that! Please tell me how much I owe you and i will PM you my address.
Thank you
Great. You know how I did it. I used a small blob epoxy (under each chip) to hold the chips in place before I soldered them in. That way, I was able to align them perfectly in place before the epoxy set (I did that too for the chip ram)... Now I just 3 cap away from powering my board up....Oh I did four chips at a time....

Right, good news, possibly on more than one count!
I programmed the LSI1024 tonight and it programmed in one go which is better than mine did when I programmed it. I had to go over mine 3 times before it would fully program. One thing though which I had completely forgotten. Even when I powered the LSI from the programmer the software still reckoned VCC was at 0v. Curious since I'm sure I didn't have any wiring wrong. I just disabled the voltage check and it programmed / verified just fine.
Point is though that those Chinese programmers you have could still be OK yet. If there is any option in the software to disable the check for chip presence or chip voltage, go ahead and try selecting that. You never know it may go ahead and program it anyway. I don't believe you can damage the chip. Don't take my word alone for that but I believe the worst that could happen is you end up with a chip that is only partly programmed...

Hi. You should now run a solder wick along the chip. That way you'll get a better looking solder joints..

:-D Thanks, I hadn't even thought of doing that just for the aesthetics, even though I use the wick on these all the time when the solder runneth over! I'll give it a try.
Guys it's done PHEW!!! My board is finished (Started building it just before Christmas).. All I have to do is to check the board over for any visual soldering and other problems before I power it up (QC check in my home).. However is there any jumpers that I have set first..
Oh for this board I'm gonna use a new 2.5" 30GB hard-drive, as it'll load WB a-lot faster than a CF card can (Though I do have one in my A1200)

I'll let you know tomorrow. What can go wrong. Maybe popping sounds eh??. If it don't work then I'll donate the board to Amibay lol, and I have bought a new 321 USB Blaster programmer (Not on eBay). It can program 3 type of chips. The Lattice which is used on the GBA1000 and the Xilinx chips that are used on the 060, and the Picasso-II card, so that's why I bought it (Have to be ready)....
