No, it was the 43P for sure, a gray (the 44P was black) system with 43P on the badge. And the model was 7043.]]></description>

					<description><![CDATA[I&#039;ve spent a fair bit of time with using a regular trio64v+ with the gxt110p (huge thanks to tenox for sending a rom image to me, I finally don&#039;t need my laptop tethered to my rs6000!), and here&#039;s some things I&#039;ve come across with it-

The gxt110p rom is 64kb, while most PC video card roms are 32kb. You will need a 27c512 (or compatible) rom chip for the image to fit. 

The card I used only had 1mb of ram, and on AIX the image was very glitchy with this jailbars pattern on both console and X; it was practically unusable. I think this is because AIX assumes the card has 2mb of ram like an actual gxt110p does and is trying to lay the image out into parts of memory that don&#039;t exist. I upgraded my trio64 to 2mb, and the jailbar pattern went away, so that does looks to have been the case. Windows NT and PROM did not have this same issue with only 1mb however, and the image was fine. 

So key takeaways if you want turn a regular trio64v+ into a gxt110p are to use a 27c512 rom (they&#039;re pretty cheap on ebay), and if you want to use it with aix make sure your card has 2mb.

 I do wonder if the rom could be reduced at all, like people have done with ppc mac roms for use on regular pc video cards. That&#039;s way outside my knowledge though.]]></description>

Sure you don&#039;t have a 44P, that speed sounds familiar to the one I have. If that&#039;s the case then it&#039;s not even powerpc, but rs64 (a derivative of power3)]]></description>

					<description><![CDATA[What CPU is in your 43P-140? Because years ago I&#039;ve tried installing NT on one of them and failed. I&#039;ve used an old Matrox, one that was working with no problems with NT in an E20. My 43P never managed to boot from the ARC 1.51 disk, the same disk I&#039;ve used in the E20. I&#039;ve seen NCommanders video and his 43P has the 200 MHz CPU and mine was 332 MHz.]]></description>
