Need help on DEC cards & drives

Hi; I need some help IDing some DEC cards; What is a PMAG-E & a PMAD A used on? How can I identify the quantity of VRAM on the PMAG-E? What is the small memory card on the same? All the slots are full. How big is a RF35-EA drive? RZ25, RZ26 & RZ28? How much memory on a M7622-AV, a M7622-AP and a DataRam 63015 (180010002)? These are in the VAX 4000/200. How do you open the case on the 4000 to see if it has any drives? I got the front panel open. Is an Emulex QD2110202 a Qbus ESDI or MFM drive controller? What is a Microtech MT CIQBA+? How much ram does a M7608 BS have What is an AH-132-06? 6 wide card, prob. Unibus. One is marked CPU Nissho. What is DEC MS02-AA memory used on and what size are they? Thanks for all help.
