MUAHAHAHAHAHAHAAAAAAAA!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I accidentally buttoned up all three of my Classics in just the right combination that one of them worked after a fashion! So I tore down the long since discharged 128k->DayStar->Plus->MicroMac'030 and hot swapped the working CRT, MoBo, A/B combo into the DayStar branded front bezel/clean chassis. It won't boot from the 20SC that I got in a deal for one of them, interesting story, that.* I don't have a Floppy on hand to try that and no time to do anything about it right now . . .
. . . luckily, it was the MoBo with the Killy Klip on board that works, the other MoBo tested unsuccessfully . . .
. . . it boots up to the :?: with its '030 MicroMac Accelerator plugged into the KILLY KLIP after the first two test runs . . .
. . . so, of course, I'm
already toying with the notion of having a run at this hack! :
BTW, is it common knowledge that a Plus with a bad FDD will boot to a non-flashing :?: or was this just a fluke? Seems more like an elegant error message to me.
At any rate, I've come up with another couple of variations for the direct connect approach and a better process for the Controller removal/machine pin socket/PCB adapter approach I floated previously.
A. It looks a LOT easier to me to solder the 50 pin ribbon cable to the underside of the board so:
__route the ribbon cable (hot glued to the solder side of the MoBo) to the top side . . .
_______directly up to the front of the MoBo and then bring it back around and through to the openings in the chassis . . .
_______turn the cable and pass the split halves up and around the MoBo in the opening opposite the reset switches . . .
______________ or do a couple of different variations based upon using the handy little internal SCSI extension cable I've got on hand.
B. I had a bookmark/link to replacement SCSI controllers (along with a relatively affordable SCSI->PCMCIA/misc. chiplet adapter) on an Amiga oriented site, but I seem to have misplaced it. This brings me to the thought of simplifying the controller removal process. Grind the legs off the lil' B*****D from the top, and then winkle each pin out of the MoBo with braid and
then install the machine pin socket. Then test the board with the replacement controller before moving on to the socket/header adapter PCB development.
I'll do a layout of the physical form factor and thru-hole locations of that bad lil' boy in AI9 and post it here for markup. I'll be doing a similar diagram for markup so we can clearly delineate the Ribbon Cable Split->Controller hack at the same time.
While I'm at that, I think I'll also have a run at a DIP ROM socket->ROM SIMM adapter board for the low end of dougg3's ROM SIMM. If he chimes in to determine that this approach might prove to be an interesting way to render the internal SCSI hack superfluous or just icing on the cake. [

Since I've got an extra Plus with no MoBo, rusted Chassis and bad(?) A/B, I'm going to take a file to the FDD opening and make a run at as stealthy an internal ZIP installation as is possible.
Other than these few thoughts, I'll probably do a little post-processing in the background while in file sculpturing trance . . . [
