Hi! I have a problem that I am hoping someone can help me with. I installed a (new) A1000 Inboard in my A1000, and followed all the instructions. To be safe, I even grounded the PALs. The *darn* thing does'nt work. On power up, it seems to go through the hardware checks OK (blinking leds etc), then prompts for Kickstart. It seems to load Kickstart for a while (maybe, all of it ?), and then comes up with a blank screen (not dark) and hangs. There is *NO* Workbench prompt. The instructions say that if too many expansion devices are connected, or a hard drive is connected or other video devices such as frame grabbers etc are present, then the system will not *LOAD* Workbench. Does this mean *LOAD* or *PROMPT* Workbench ??? Further, I DO NOT have any expansion devices other than the 256K front panel and a second floppy. I even tried without these devices - yet no luck. Should I follow Spirit's suggested cure -- which is to replace two PALs on the daughterboard with faster PALs. Anyone done this ?? Anything I should know about this ?? Should I get the PALs from Spirit or can they be got from any IC place (Radio Shack etc). Any insight/cure for the problem will be greatly appreciated !! Thanks Yaseen

It was suggested to me by several kind people on the net that we: 1) ground our pals 2) terminate our bus 3) replace the pals to overcome similar problems (will not load workbench) when adding a CMI accelerator to a A1000 with a Starboard. We first determined that the CMI would run without the Starboard, we already knew that the Starboard would run without the CMI PA. We first grounded our pals -- did not help. Then we built a bus termination circuit on a card. It cost about $40 and fixed the problem. The A1000 now also seems to be resistent to inexplicable lockups and crashing. I recommend this effort and cost if you plan to keep your A1000.
