Any other files text or otherwise welcome also to this address or drop us a dropbox link The Sun workstations I never knew too much about as at the time did not seems like old history nor did we use any so playing catchup!

The PSU and an assembly that holds the drives fills the top half. A 3.5" half-height drive fits in one side of the assembly and a 3.5" floppy drive fits in the other. The PSU cables go from the rear to the front of that side of the chassis, below the FDD (when the chassis is closed). I did an exhibit on Sun lunchbox systems, including the IPC (4/40), for PNW VCF earlier this year. I looked for press kits, posters, etc. to use in the exhibit, but could only find text files. I know people who worked at Sun on the development of those early SPARCstations and none of them had any of that kind of material. I had an audio cassette "Introducing the IPC" for Sun sales. I donated it to CHM this year (but I ripped the audio before I sent it to them). alan > On 12/2/18 10:13 AM, ED SHARPE via cctalk wrote: > Thanks for the info to get it open! when back at the office shall do that.. there may be drives in 2 places - on board and the off board one.

I do remember lusting after one of these 1U COBALT servers when they were current didn't have anything in the budget back then though for one. I have been told SUN eventually ended up owning COBALT. > > As will all that we have we are looking for any ad slicks press kits posters, wild artwork for the Sun $/40, and the 2 COBALT machines.. > > Ed Sharpe archivist for SMECC www.smecc.org > > > > > In a message dated 12/1/2018 8:15:39 PM US Mountain Standard Time, aperry at snowmoose.com writes: > > > Yes. It is next to floppy in the upper half of the chassis. There is a 50-pin (IDC connectors) ribbon cable that goes down to system board at the bottom of the lower half of the chassis. The chassis splits in the vertical middle in a, if looking at the chassis, fairly obvious place. Because of the cables that run from the top to bottom, it effectively hinges at the front of the chassis. There a couple buttons on the side to release and sometimes a security cable bit to remove (phillips screw). > > On 12/1/18 7:08 PM, ED SHARPE wrote: > Hi Alan - The hard drive is same size cabinet.... with I guess a SCSSI cable.

If the PS on the IPC that you have now doesn't need to be re'capped now, it will need it soon. After that will likely be the HDD that needs work. Almost all of my HDDs that originally shipped with lunchbox systems up to the 424 meg (ST1480N) have died. The price for working 50-pin SCSI HDDs are at a point that SD2SCSI parts make more sense (unless you want to exhibit them as they originally ran). > > alan > > On 12/1/18 6:55 PM, ED SHARPE wrote: > BUMMER > It may become a static display..... > > Ed# > > > In a message dated 12/1/2018 7:53:44 PM US Mountain Standard Time, > cctalk at classiccmp.org writes: > > A 4/40 is a SPARCstation IPC.
