Help ZT-180: PDF reader and memory upgrade

[ZiggyDroid]

Hello all. I am new to the forum and I had a couple questions on my ZT-180.

1. Is there a good PDF reader out there that will read large files? I am trying to read my D&D books on my Zenithink and i can't seem to find a PDF reader/viewer that will work. I got close with Office Suite but it gave me an out of memory error, which leads to my 2nd question.

2. I have read in intermittent spec sheets that the Zenithink ZT-180 has 256mb of DDR2 in it and is supposed to be changeable. Has anyone torn there's down too see if the memory is replaceable and if so upgradable? I bet this thing would fly if it had 512mb or even 1gb

Thanks in advance for any help provided

had mine apart the other day to mod the wifi by soldering a length of wire on the ariel, i've not noticed any difference by the way.
i did't notice any ram modules under the bonnet, but i did't look that hard, i can only think the ram is surface mount ddr2 which unless your a soldering god, i would't entertain the idea of trying to change, also there must be some kind of bios/cmos and if you did manage to change the ram modules, the bios might need updating. though i might be wrong completly.

Good advise!

If they did surface mount the modules to the system board it's probably not prudent to make any major modifications. Most modern computers (I can only assume that the Chinese manufacturers follow the same principals) use multi-layer circuit boards. In this case it would be nearly impossible to accurately re=solder the main board without causing other damage in the process.

defo agree.
