what do you mean??

mine has 24 meg installed.  i believe there was a version of the
3/60 that only did 12 meg..

    3/60
        Processor(s):   68020 @ 20MHz, 68881 (stock), Sun-3 MMU,
                        8 hardware contexts, 3 MIPS
        CPU:            501-1205/1322/1334/1345
        Chassis type:   wide pizza box
        Bus:            P4 connector (not same as P4 on 3/80)
        Memory:         24M physical, 256M virtual, 200ns cycle

    3/60LE
        Processor(s):   68020 @ 20MHz, 68881 (stock), Sun-3 MMU,
                        8 hardware contexts, 3 MIPS
        CPU:            501-1378
        Bus:            P4 connector (not same as P4 on 3/80)
        Memory:         12M physical, 256M virtual, 200ns cycle
        Notes:          A version of the 3/60 with no onboard
                        framebuffer and limited to 12M of RAM (4M of
                        256K SIMMs and 8M of 1M SIMMs).



maybe you have the LE version.

services required? hmm  i'm assuming netbooting here...

nfs, bootparam, tftp, rarp, portmap,    i think thats it...

i think the only security risk you run is the tftp.  but if you set
it up right, it should be pretty secure.
