Another A1000 resurrection w/goodies
« on: April 03, 2011, 05:33:53 AM »
Inspired by TheGoose's thread on bringing his A1000 back to life, and not to hijack his thread with my work, I have brought my A1000 to life and done some... horrible things to it. :D

I went ahead put my flakey Derringer into the system and found that, yep, it's still pretty flakey.  Sometimes it will see RAM, sometimes not.  Most of the time if it sees RAM it sees the wrong amount, usually only 2MB.

The Derringer is the top of a CPU socket stack of three expansions: AdIDE2 on the bottom, with a Kwikstart II in the middle.

I'm not actually sure the AdIDE2 is working where it is, since boot takes no time at all to fall over to the floppy.  I would expect that there would be at least a few seconds delay on the IDE.

Nice.... but can you put the internal floppy drive where it belongs and close the case?  :lol:

Matter of fact, no I cannot! :roflmao:

@TheGoose: I suspect your suspicion of a ground problem may be applicable here.  I fired the beast up this morning and, after booting, was able to get the system to see the 32MB SIMM.  After which it immediately locked up.  I can imagine the puny socket is not able to supply the ground and/or power all the way up the stack which the Derringer needs to operate fully.  I am going to find good points from which to draw power and ground from the motherboard, and good points to which I can apply them on the Derringer.  Probably play with that later this week.

@Xanxi: Yep, you found it!

Mine is shaping up like this LoadWB,

bottom (A1000) -> AdIDE -> 1meg insider -> kwikstart II on the top

I am wondering if the order of the AdIDE2 and Kwikstart II makes a difference.

What is the Kwikstart jumper set to (DF0: or ROM) ? ROM I would think.

Really cool!

ROM.  Thank you, this is all your fault, after all.  I wonder how many of these "revived 1000" threads we're going to see now :)
