This is the inside of the 3/80. It has four banks of 4M SIMMs (four SIMMs per bank). (The other 2 banks are under the bwtwo graphics card.) I was able to use 4M SIMMs because this 3/80 has PROM version 3.0.2. Strangely, the 3/80 has two SCSI bus connectors, the first one has been used by my Quantum Fireball 2G disk (I don't recommend Quantum's for anything, but that's anouther story). The other one is unused. I'm not sure why there are two connectors, I know that the 3/80 only has one SCSI controller. (I guess it's like a Sparc 10 with the two SCSI connectors). The 3/80 could have also had a floppy drive, but this one didn't have one. |

This is another picture of the 3/80 sitting on top of my Ultra-1 (the
U1 was used as a terminal for setting up the 3/80). I had the disk sitting
on it's side to make sure that the 3/80 was booting off of it instead of
the network. (I bought a new NVRAM chip for this machine and had some problems
with booting.) Many thanks to Peter Koch in Germany and http://sun3arc.krupp.net/
for helping me thru the NVRAM programming process and other important
info! (The stupid NVRAM chip has a battery in it! And, of course, the battery
died along time ago and all of the original's NVRAM's memory was erased. Peter was able to supply me with the NVRAM's original data for the new NVRAM chip! (based on the PROMID printed on the top of the old NVRAM chip.))
Here is it's important info: PROMID ETHERNET_ADDR HOSTID DATE_PROGRAMMED
