Hi folks, A few of you might remember the Jupiter Ace I had that took a 9V spike to the expansion slot -- and my futile attempts at repairing it. It's been well over four years since I sent it to a listmember who offered to repair it, and all attempts to get the board or the spares I sent with it have failed. At this point, I haven't seen hide nor hair of him in months, although he's apparently still updating his website... So basically I'm the proud (?) owner of the two sections of case, most of the snap-rivets (apparently Maplin sell these, so I might be able to complete the set), the rubber keyboard membrane, documentation, demo tape and a (supposedly working) 16K RAM pack. I've heard rumours of spare, unassembled Jupiter Ace PCBs kicking around; does anyone happen to have one up for grabs? It looks like the only way I'm going to get this thing up and running again would be to build a new mainboard need are a Z80 CPU and a couple of 74LS logic chips. Only other alternative would be to get a few PCBs made up for it, then build one from scratch on that -- the catch being I haven't had any luck creating a decent track master from the scans of the PCB that I have.... Can anyone assist me in my Quest to Build a Working Jupiter Ace (tm)? Thanks, -- Phil. classiccmp at philpem.me.uk <http://www.classiccmp.org/mailman/listinfo/cctalk> http://www.philpem.me.uk/ -----REPLY----- Hi Phil, If it were me, I would just take the information from the wikipedia page and build your own replacement PCB. The Jupiter Ace appears to be a pretty straight forward Z80 SBC so just build a prototype board and then get KiCAD and design your own PCB. With some luck and patience you probably can design a board that fits right in the original case. You might even be able to recoup your costs of the PCB manufacturing run by selling PCBs or even fully manufactured SBCs to other Jupiter Ace enthusiasts. I'd guess they'd be thrilled to see some new hardware available. Just a suggestion. Thanks and have a nice day! Andrew Lynch
