Unserviceable Slot Interrupt!!!!! [
] ]'> YAY!!! Success . . .
. . . sort of, so far so good anyway! :approve:
And, amazingly enough . . . nothing had released the magic smoke to this point! 8-o
In this config I got the Radius splash screen, and then a boot to this error:
00000003
000000ff
Dunno, something like that, should have written it down . . .
. . . machs nix, when I hooked up the 12" RGB 'zaTopper after doing the documentation pics, I got the far more welcome error at the top of the post along with the Radius splash screen.
This was the fail at doing the machine pin Hack the way I'd originally envisioned doing it . . .
. . . but the bent to hell and gone 40 pin DIP socket, witha few machine pin legs for support on the opposite side, did do a great job of applying the gravitational force from a 1 1/4 inch, half inch drive Socket to the SIP Machine Pin strip . . .
. . . very sketchy result, so I started nipping pins off the Machine Pin Header Strip and tried a few approaches to the soldering . . .
. . . I finally resorted to doing one fluxed pin at at time on top of a Ball Grid I laid atop the soldertail cones of the DuoDock Gemini Card . . .
. . . great feedback when the downward force on the matchstick settled the machine pin onto the ball-melted slodertail cone after heating the pin itself . . .
. . . . here's the more refined version I posted of the prospective hack on the previous page . . .
. . . and here's the first run at FuglyTyping the hack . . .
. . . and a look at the topside connector/board section to be excised from the Gemini Adapter . . .
. . . and another . . .
. . . and this is a better overall look at this most evil hack. }
Now to address the interrupt/addressing issues and figure out how to switch the power and ground lines of the Gemini card straight to the board level inputs of the ATX hacked PSU to get around the Power Budget bludgeoning of having a Rocket AND a second NuBus Card hacked onto the IIsi NuBus Adapter.
The Rocket alone is faaarr outside design specs fot IIsi MoBo and NuBus adapter all by itself.
Question: Is the power/ground service from an ATX MoBo Connector clean enough to route to the Gemini Card without line conditioning? :?:
Next Step: Lop off and clean up the top section of the Gemini Card to see if I can at least get the same results, or document any reduction or improvement in the address/interrupt train wreck. I'm figuring that removing some pins and patching to the proper address/interrupt lines on the RAW PDS pins of the NuBus Adapter might enable both NuBus Slots, leaving me a third set for the basement PDS hack.
