>From the EIA/RAM Combo Board Installation Guide, page 2:
RAM W1 W2 W3 Rows populated with RAM ICs
0.0MB - - - none
0.5MB - IN IN 5 & 6
1.0MB IN - IN 7 through 10
1.5MB IN IN - 5 through 10
With "w1 and w2 are capped, and w3 is not" you can fully populate the board
using "standard" 256Kx1 150nS DRAMs (faster parts will work, too, but DON'T
make the board operate any faster and are usually more expensive; note, though,
that the price of 100nS 256Kx1 DRAMs in this area is about US$1.20 each.

No software needed just for RAM. You should TOSS the disk that accompanied
the EIA/RAM Combo Card whose contents (as recorded on my system) are:
thadlabs ksh 24659/24687> cat /usr/archives/floppy/AT+T/EIA-RAM_withHW
EIA/RAM Combo Expansion Board Disk 1 Disk each
0037406-0R01-0382-X Ver 3.0 (accompanied expansion card purchase)
0037406-0R01-0383-X Ver 3.0 (accompanied expansion card purchase)

and, instead, use the disk that accompanied the 3.51 Foundation set whose
contents are (as recorded on my system):
thadlabs ksh 24659/24687> cat /usr/archives/floppy/AT+T/EIA-RAM_Combo
EIA/RAM COMBO BOARD EXPANSION DISK 1 Disk

100755 bin 2076 Jan 1 10:10:00 1970 cmbupd
HOWEVER, please note the FIXDISK 2, in the kernel directory, contains:
total 338
-rw-r--r-- 1 root users 206 Nov 22 1989 Info
-rwxr-xr-x 1 root users 1326 Dec 6 1989 Install
-rw-r--r-- 1 root users 21 Nov 22 1989 Name
-rwxr-xr-x 1 root users 131512 Nov 22 1989 UNIX3.51m.z
====> -rw-r--r-- 1 root users 4933 Oct 3 1989 cmb.o.z <====
-rwxr--r-- 1 root users 33410 Dec 2 1989 wind.o.z
so you'll probably need to re-apply that portion of FIXDISK 2 after you load
the 3.51 combo driver (for its shell scripts, cmb.rc, etc.). And note that
the "*.z" files are restored using unpack (whereas "*.Z" files would be
restored using uncompress).
If you didn't get ANY disk with your EIA/RAM Combo Card (you didn't say),
then lemme know and I'll uuencode, shar and email you the stuff for 3.51 since
you're ENTITLED to that software because you have the EIA/RAM hardware card.
BTW, as a general tip to EVERYONE, please note that I made "listings" of all
the software disks that accompanied my 3B1 purchases in the form shown above;
makes it real handy to "grep" to find what came with what and to check the
original dates and sizes of things.
