I have never seen anyone try to compile the CG works from this ALPS CD, which is no longer in production or floating about the web. These are all the images I could compile from it, though I'm sure some are missing in regards to Zeta Gundam. I have spent a long time trying to find out more about this CG set as is, but not much information is present on the web anymore.
From what I do know, it was released in 2004-2005 through mail order on the ALPS doujin circle page here: http://luckypuffy.sakura.ne.jp/alps_classic/cgi/zaiko/zaiko_list_alps.cgi?1&0 and here: http://luckypuffy.sakura.ne.jp/alps_classic/html/books/power_cg_01.html
It mentioned being available via DMM also, however its nowhere to be found as of today.
These were drawn by Ohio-Shuu Riki (オハイオ州力), known for his uncanny ability to draw on model mecha anime characters. ALPS as a doujin circle was active between the late 1980s until about the early 2000s from what I understand.
If you own anymore images unlisted or have any information about this CD, please let me know or contact me at Adoggoart on Twitter.
*Also included in this CG set are images archived from the ALPS website pertaining to the CG set itself.
