The answer: The only way to go beyond 16 Mbytes in an SLC is to
upgrade it to an ELC. Not even 3rd-party memory supplier Clearpoint
(I called them) offers a way to do go beyond 16 Mbytes on an SLC
board.
Sun offers an ELC upgrade. I have not investigated the price
(since I think it very unlikely we'll go that route).
Here are some edited-down summaries, ending with a detailed description
of the ELC and the upgrade from SunFLASH. In addition to the people listed
below, I received replies from

16MB is the max...
From: Doug Neuhauser <doug@perry.berkeley.edu>
No.
From: Marcel Bernards <bernards@ecn.nl>
According to my information , it's not possible to exceed the 16 MB limit
on an SLC now. (36 bits 4Mb simms)
The ELC can, but they use the new 33 bits 16 MB simms (as the IPX).
The only thing you can do now is to order an SLC->ELC update.
In fact, it's just a new board plugged in the back of your SLC.
It roughly doubles your performance.
From: mark galbraith <deltam!dm!mark@uunet.uu.net>
As far as I know, you have max'd out this SLC. The SLC is only able
to use 4Mb SIMMs and there are only four slots.
From: Guy Boudreault <boudreau@macgyver.crim.ca>
By upgrading your SLC to an ELC you could use the ney 16Mb. SIMM available.
You can put 64Mb. total in the new machine
I include a SunFlash article on the upgrade.
Good luck.

The Florida SunFlash
SPARCstation ELC
SunFLASH Vol 31 #25 July 1991
----------------------------------------------------------------------------
- Industry's highest performance, entry-level monochrome RISC workstation
- 20.3 SPECmarks and 21 MIPS in an enhanced CPU-in-monitor package
- Up to 64MB of RAM using 4 and 16-Mbyte SIMMs
- New "pop-top" CPU access door for easy service,
memory upgrades, and customer installable system board
Available Configurations:
- Diskless, 8-Mbyte ELC (4/25FM-8)
- New 8-Mbyte ELC diskfull package
with 207-Mbyte Desktop Disk Pack (4/25FM-8-P45)
- SPARCstation SLC board-swap upgrade to SPARCstation ELC
available (UG4/20-Q)
The SPARCstation ELC is Sun's high performance, entry-level replacement
for the SPARCstation SLC. The ELC is targeted for Sun's most price
sensitive customers in DBMS, Document Image Processing, Software
Development and Education. The heart of the ELC is a new integrated
SPARC integer and floating point unit. The new SPARC chip represents
Sun's highest level of integration to date and delivers sustained
performance of 20.3 SPECmarks, 21 MIPS and 3 DP MFLOPS.
Like the SPARCstation SLC, the ELC utilizes a small, convection cooled,
17" monochrome monitor package, but includes some important
improvements. The ELC display provides antiglare, antistatic, and
anti-magnetic properties which comply with German GS and Swedish
MPR--two of the world's toughest benchmarks for ergonomics and health.
In addition, the monitor enclosure has been modified to include a "pop
top" CPU access door. This door snaps off to allow E-Z service,
memory upgrades, and customer installation of the system board. No tools
are required.
The SPARCstation ELC is a higher performance version of its predecessor
with several important improvements. It is positioned as a
client/server workstation alternative to minicomputer-attached
terminals and networked PCs where color, SBus expansion, and internal
storage are not required. Like all Sun workstations, the ELC is also
available in a cost effective file server configuration.
