Memory sweetspot?

I'm planning to run OPENSTEP/Mach 4.2 on a SparcStation 20, I have 192MBs of RAM in it now, is this enough or do I need to rip apart more Sun boxes to add memory to the SS20? What is the minimum amount of RAM an experienced OPENSTEPer would run with?

I'm going to use the machine mainly for fun and will run X11 on it.

Thanks for any thoughts on this!

If you think that the original machines came with much less than 128MB (like 32MB), I think you'll agree that 192MB will be plenty. Of course if you're going to use memory hungry applications (X not being one of them), then you will need more. I think you're just fine. Start installing ;)

For most the apps you'll find for OPENSTEP, 64 MB is a good minimum. I have 80 MB in my ThinkPad and 128 MB in my SPARCstation 10.

With those amounts I'm able to work on pretty large multipage layouts within Create 5.2.1 and still have a number of other apps open. For image intensive layouts of 10 pages or more I move to my PowerMac 8600/300 running Rhapsody 5.6 which has 416 MB of memory.

As I recall, OPENSTEP tops out at 512 MB of memory.

If you are at 192 MB now, I doubt you'll get any more performance out of your system by putting more memory in it. NEXTSTEP and OPENSTEP apps weren't the memory hogs that todays apps are.

Sounds good. I'm having the harddrive exchanged this sunday (it wont spin up anymore the poor thing) so I guess come monday i'll be installing!

I have 256mb in my SS5 with NS3.3 and it's speedy to say the least.  

In my experience my with my NeXT machines in order of fastest to slowest

1. Sun Sparcstation 5 110mhz 256mb

2. Canon object.station 486DX4-100 96mb ram

3. NeXT Turbo Dimension Cube 128mb ram 64mb Dimension ram

4. NeXTStation  Turbo 128mb ram

5. NeXTStation Turbo color 128mb ram

6. NeXTStation 128mb ram (Turbo chip set mb with 25mhz chip)

6. NeXTStation 32mb ram

7. NeXTStation Color (I can't remember the ram in this one)

I would agree with the previous poster, 192mb is more than enough ram for NS.

Yay! I have it up and running and have TCP/IP up to. No I just need to figure out where I set the name server and I'm good to go. :)

Looks nice and some things are amazingly OS X-like.

As in virtually every older version of UNIX, DNS server names go into a file named resolv.conf in /etc (link to /private/etc for NextStep, of course).
I'm at work (and no NeXT computer around :-( here) so can't hit my own man pages but have at look at the online ones at

http://www.vorlesungen.uni-osnabrueck.de/informatik/shellscript/Html/Man/_Man_NeXT_html/

and have a look at resolver(5), that is, the page named 'resolver' in section 'man5' (and ignore the note about this file not normally being used - you very much do need it).

I upgraded my RAM to 256 MB but I have to wonder, was there ever an OPENSTEP-version that supported SMP?

I have 2 SuperSparcs (at blazing 50MHz speed) in my machine but only one is being used right now.

Or is there a soopersikrit bootswitch to get SMP?

Sorry, SMP is not available in this old Mach kernal...

Certainly it would be nice, but you can also have higher performance by getting the 75 or 85MHz SuperSPARC-II (versus the SS-I you have) - should still be available on occasion on eBay (& very cheap). Do your CPUs have L2 cache? Have a look at the excellent http://mbus.sunhelp.org to find out (look under 'Modules').

I'm totally unsure if my CPUs have L2 cache even with the website you pointed to. :oops:

I got a 100MB network card today and a ConServer-1053 SCSI-FWS Host Adapter for my SS20 and I have a second SS20 inbound with 2 HyperSPARC 150MHz processors and 336MB RAM (it also includes 2 50MHz CPUs).

From what I understand OPENSTEP does not run on HyperSPARCs and I feel pretty awful having 4 50MHz SuperSPARCs but no SMP support. Maybe I'll get yet another SS20 with just one SuperSparc (and maybe one of the faster ones). :)

...or maybe I can run OpenStep/Solaris on the HyperSPARCs?

The 100MB network card has a port that says MII, since it predates the Nintendo Wii by quite some time I wonder if someone knows what a Mii port is?

you have quad sparcs in one ss20?? ill trade you a supersparc 75mhz for those dual boards ;)

A little off topic, but seeing all the Sun guys here I thought I'd ask: I'm cleaning out some of my stuff, so I was curious if there is any interest from the NeXT folk here in a working Sun Station ELC and a working Sparc Station IPX (both Lithium-battery enabled, plus various other things like keyboards, optical mice, 13w3 cable, 13w3 19" screen, CDs with software, whatever manuals I can find, maybe a SCSI tape drive, a rare Sun watch, etc) ?  Not sure of a price yet, but if interested feel free to make a bid (via PM, or wait until I make an inventory and get photos and add a thread in the marketplace section). I'd give preference to SF bay area people, but I'll probably ship as well.
