| Macintosh ED purchase with surprise! | |
| Posted by: CharlieFrown on 2016-08-05 10:15:27 Look what I found inside 512ke (ED) I had bought...  | |
| Posted by: just.in.time on 2016-08-05 11:33:45 That's impressive! All for the SCSI, or are there two separate upgrades there? | |
| Posted by: CharlieFrown on 2016-08-05 13:22:48 two separate upgrades: SCSI plus memory. | |
| Posted by: just.in.time on 2016-08-05 13:56:13 Very nice, sweet find! | |
| Posted by: tanaquil on 2016-08-05 14:39:09 Nice! I have an upgraded 512Ke like that, but mine doesn't work. It's on my list of machines to fix when I finish fixing up my workbench. | |
| Posted by: BadGoldEagle on 2016-08-06 02:29:10 That's a nice upgrade! Hope you have the scsi cable as well! This one added a port on the back where the battery lives, right? | |
| Posted by: jsarchibald on 2016-08-07 15:42:21 I got a similar thing with an ED I bought a few years ago. It is probably the cleanest compact Mac I've come across to date, and it had a 2MB RAM board installed. Love these things! I also have an SE with a Levco board in it, and another SE with some other card (can't recall as this time, Advanced something?). Enjoy! | |
Posted by: CharlieFrown on 2016-08-08 23:58:54That's a nice upgrade! Hope you have the scsi cable as well! This one added a port on the back where the battery lives, right?yes it did ! 🙂 not being ecstatic about it right now, it gives me 02xxx RAM related error. Does it add up another 512k to existing RAM or totally bypasses motheboard mem adding full 1 MB? | |
| Posted by: BadGoldEagle on 2016-08-09 03:54:55 We've got to get this thing back up and running! I think it adds another 512k of RAM on top of the onboard 512k. You should google whatever's written on top of those chips to find out. I believe the sad mac code is irrelevant here, since this is a 3rd party extension. Unless.... Is it possible to remove the daughterboard? I don't know how this was connected to the Logic Board: Killy clip on top of the MC68000 or on top of the original RAM? If it is possible, then you should try to boot it up without the MacSnap. Maybe the board is misaligned ? If possible you should reseat it. Side note: Killy clips are very delicate things, and they can break easily. Just don't apply too much force. | |
| Posted by: max1zzz on 2016-08-09 05:51:31 The macsnap board adds a extra 512k iirc, It should be esay to remove and test, It just clips over 4 or 5 ic's on the board (Not the CPU btw) I have one of those macsnap boards sitting around, I brought it with a couple of 512k boards with the intention of fitting it to one, but in the end i got hold of the parts from a MacGusto II board (Which adds a extra 2mb of ram, scsi and a optional 68881 fpu) | |
| Posted by: CharlieFrown on 2016-08-20 00:29:16 fortunately it's working! Found a tip on ancient net.micro.macintosh newsgroup how to increase RAM from 1 to 2 MB. | |
