FYI there's some more info on the power supplies here:

They must be full 1MBx36-bit SIMMs of about 80 NS in order to work.

DEC Server 90TL and 900TM 4MB (1MBx36) 72-pin SIMM upgrade details:

	Digital part number:	4A-MS40-WB A01
		replaced by:	20-41141-05

	description:		SIMM 1 QUAD CAS 9 CHIPS 80 NS

	manufacturer:		SAMSUNG
	mfgr part #:		KMM5361000B2G-8 9347 SEC

In several of my 90TLs I've managed to squeeze in a double-sided SIMM,
e.g. the Digital part # 5021224-01.

The MNENG3.SYS I use with my 90TLs is also called DECserver90TL_V2.2_BL29D-52M

The copy I have appears to be a special build done for someone by
Cabletron.  All I know is it works reasonably well (and one heck of a
lot better than the old 1.0 NAS! :-)

The manual you're probably looking for was, until recently, here:

Google is still serving up the text and html translations though....
