More on Rampage...
OK, following on from Johns pics of Rampage, the following are excerpts from the actual engineering logs from 3dfx’s intranet:
11/15/00 5:27 pm
Stuffed Rampage bringup board being reworked. Rework is fixing power supply connection issues.
Estimated time to completion "a while". Probably about 8 hours to rework and verify.
11/16/00 3:20 PM
With a lot of work, the board engineers have been able to rework one bringup board. We currently have applied power to the first Rampage chip.
Bringup of the chip is underway.
We are continuing to work on a clean up of the database for the first bringup board.
11/16/00 8:45 PM
The engineers have been working thorough intermittent contact problems in the socket area this evening. Progress has been slow because the chip responds for awhile then stops responding.
11/17/00 5:35 PM
Rampage bringup has made little progress today. This morning the engineers were able to read a few registers before the board stopped working. During the day the debug effort continued to point to socket issues. Therefore, we are currently mounting a chip down on the board in an attempt to make more progress. In addition, we are completing three more of the initial bringup boards. We are planning on reworking at least one more board.
The respin of the initial bringup board is underway. The current target for completion of the respin is Saturday about noon. We will not attempt to fab more boards until we have high confidence in the database. We will quick turn 3 to 5 boards to make sure the board is correct before building any larger quantity.
The second bringup board is continuing to make progress in layout including incorporating the new chip model. This board may be ready for fab by the middle of next week.
No updates for a few days, but was told: “Current word is that the version A0 board is responding better now that they have a solution for the (electro-)mechanical connection problem with the socket. A Vice-Grip(c) is involved ....” – that’s what you saw in Johns pictures.
Another update (from the Rampage ‘big Cheese’):
I received no more logs from this point, but put the following together:22/11/2000
Here is what has happened in the last 24 hours.
The new version of the initial bringup board bare fab arrive this morning and was sent to the assembly house. We should get new stuffed boards back Wednesday afternoon. The socket fits well on the new board.
Our next big push needs to be to get the memory working and stable.
We got the DAC's aPwr and GND hooked up, and now we get relatively clean and stable garbage on the video monitor. We've been able to flash and read the ROM reliably, although there may be work left in the 32K-64K address range. We're bringing up our second board with Joe Minacapelli's patented socket holding device, and other rework to ensure stability.
PCI clock insertion workaround and PCI clock PLL fixes are underway.
We've been able to do a 2d blit, but because the memory system's not stable, it didn't look perfect, but it did look like it did a blit.
We tried bringing up the windows driver with Rampage as the secondary device, and it recognized the card, and allowed us to debug some
of the modeset code.
Rampage is running but there are some stupid bugs. The DAC output is reveresed ... high is low and low is high which turns out to be rather sucky since displaying is difficult. Looking at a dongle to invert the inverted output.
Flash rom bug where part can't be written...
Fixes for both are possible in metal layers.
5 boards are operational.
DAC output ‘dongle’ fitted.
Rampage running D3D applications.
And soon after that the D3D DX8 demos were running and Quake3 debugging in a window (which we’ve also seen pics of).
