Experiences with 3/160 -> Sparc Upgrade?

[John Valdes]

We have a Sun 3/160 which we are thinking of upgrading to a Sparc.  Has
anyone done this?  What have been your experiences, good and/or bad?
Exactly what type of Sun will the 3/160 become after the upgrade?  (I
realize the upgraded CPU is a 4300; I want to know if the Sun will be
4/370 or 4/380 or whatever).  Also, any comments as to which of the
following boards/peripherals will/will not work in the upgraded Sun will
be appreciated:

CURRENT CONFIGURATION: Sun 3/160C (Office Pedestal) w/

Board Name                               Sun Part #     Slot #   will work?
----------                               ----------     ------   ----------
Sun 3/160 CPU                             501-1208         1         no
Sun 4MB Memory Board                      501-1132         2         
Helios MSV-8 Memory Board (8MB)           --------         3         
Sun-3 color graphics board (cgtwo)        501-1116         4         
Sun FPA                                   501-1105         5         no
CPC TapeMaster 1/2" Tape Controller       501-1156         7         no
Xylogics 7053 SMD disk controller         501-1249         8         
Systec VPC-2200 printer controller        501-1054         9         
Sun GP+ graphics processor                501-1139        10         
Systec MTI-1600 (ALM-1)                   501-1165      11 & 12      no

PERIPHERALS:

Hitachi 19" Color Monitor, Sun Part# 365-1000-01 (?)
Fujitsu M2351 Eagle SMD drive (2)
Fujitsu M2382K SMD drive
CDC 92181 1/2" Tape drive (Keystone) (may be replaced with a CDC 92185)

Obviously the CPU and the FPA will not be needed, but how about the
memory? (My guess is no--won't work.)  I'm aware that the TapeMaster
controller will no longer work (we were planning to get a dual-density
1/2" tape controller anyway--any recommendations?) as will not the ALM-1.
Will the 7053 still work?  Any restrictions on it or the SMD drives as far
as booting is concerned?  I'm also aware that we'll need an upgraded power
supply and fan assembly (the serial # for the 3/160 begins with 624C...).
Finally, does the upgraded CPU board come with a SCSI interface?

Thanks in advance for you're replies.  Please e-mail directly to me if
possible.  I will summarize to this list if I receive any requests to do
so.
