I'll have to look that pro380 technical book up, I've always referred to my XT100 documents but those were pre-release for the Pro/350. Now for the real 50k question: Does the AVO socket next to it take the same board format for the 8 bit color video memory? Anyone have a picture of the AVO

Possible. I see that Xhomer includes a version of RT11, and when I looked at that I saw that the .MAC files for the DZ and whatever the disk is (DY?) drivers appear to be there. So it might not be impossible to write the drivers in M+ based on that. Maybe. On 7/29/2023 11:00 AM, Lee Gleason

Answering my own question: Yes it does work. My Pro/380 now sees 320kw of memory instead of 256kw. Now to buy some sockets and upgrade these boards to 256kw each. One can go in the Pro/350 and the other plus the memory boards should take my Pro/380 to almost 1kw. I wonder if the CTI memory

Meantime a question: The pro/350 has two memory daughter cards on the board. The Pro/380 appears to have a spot on the motherboard that takes the same size card. Can one use a Pro/350 internal memory board (not CTI) on the Pro/380 motherboard? Wondering before I plug this in On 7/29/2023

Copied all the files onto my Gotek, it's SO EASY to just turn a dial to select a disk! Anyway, loaded all the files, but when I try to run them it says it's missing PROF77 Common. My guess is that's the same block as F77OTS, but how does one load a common block with a different name? I
