EkriirkE Posted July 9, 2019 Report Share Posted July 9, 2019 I purchased this lot just because it was a working IIfx which I've wanted for a while but they don't float by often enough. Turns out this included a second dead IIfx from a PRAM battery explosion. I was not prepared for how large the also-included SuperMac 19" Trinitron was, but I should have known better with how well it fits above the massive Mac II series I'll attempt to repair that one as well as generally re-cap both boards. Both machines included a SuperMac video card (different models) and a third SuperMac video card was included New-in-Box It came with 4 SCSI devices; cartridge-loading CD w cartriges, SyQuest 44MB with bag of cartridges, HDD, and unknown-yet spec DIGITAL Storage Expansion box And a bag full of cables, a second AEKII, and 4 more classic rectangular mice ...Also the guy threw in the DIGITAL (DEC) lappies in with the lot when I arrived. The working IIfx also has DEC software on it. So this guy must have worked for them More pics.... https://i.imgur.com/a3znTUv.jpg https://i.imgur.com/1VkmGvN.jpg Quote Link to post Share on other sites
ArmorAlley Posted July 9, 2019 Report Share Posted July 9, 2019 (edited) Congratulations. It really is great to get your hands on a haul like this. Edited July 9, 2019 by ArmorAlley Quote Link to post Share on other sites
tokyoracer Posted July 9, 2019 Report Share Posted July 9, 2019 Wow. The only IIfx I got was bundled with a II on eBay near 10 years ago. Batteries absolutely nuked the board so I have only a IIfx without a motherboard. Even got a bunch of 64-pin RAM for it still. They're scarce even in the US, just imagine how hard it is to get one here in Blighty! Not sure if I want to just sell what I have left of it or keep it in the hope something might happen.

Unknown_K Posted July 10, 2019 Report Share Posted July 10, 2019 Nice monitor stand. I have a Supermac 19 or 20" fixed frequency monitor (uses BNC) and it is heavy as hell. Quote Link to post Share on other sites
Bolle Posted July 10, 2019 Report Share Posted July 10, 2019 (edited) Sweet. That lot was a steal. It had been sitting on ebay for quite a while if it came from the auction I think it of... How bad is the damage on the second IIfx? I have been looking for a fixable IIfx board now for some time already. Edited July 10, 2019 by Bolle Quote Link to post Share on other sites

I have been looking for a fixable IIfx board now for some time already. Vielleicht! But it only just appeared in my saved searches a couple weeks ago, so unless the seller updated the listing I can't say.... Außerhalb von MUC? The board doesn't appear all that bad from the inside the case though there are some loose floating tants with corroded legs which doesn't bode well for any nearby ICs. I haven't broken them down yet, and there are a few SMD electrolytics I want to replace. It's nowhere near as bad as the huge brown rust holes you typically see in an SE/30 Edited July 11, 2019 by EkriirkE Quote Link to post Share on other sites

It's bad but not terrible - I'm going to give it a shot. Luckily I have the other IIf to reference for parts and surface traces Edited July 19, 2019 by EkriirkE Quote Link to post Share on other sites
IIfx Posted July 21, 2019 Report Share Posted July 21, 2019 The Apple custom ASIC to the left of the Zilog serial controller might be a goner, but fingers crossed you can save this system! Quote Link to post Share on other sites
bibilit Posted July 23, 2019 Report Share Posted July 23, 2019 Probably too late, only been able to save one Logic board (SE) with this amount of acid, too many traces probably gone already. Quote Link to post Share on other sites

Just did an acid soak and preliminary scrub with soapy water. The ASIC looks fine. The Zilog is missing 1 pin which I think I can fix and the 2 onboard RAM are shot. Also lots of missing traces. Those I can handle, but I worry for the vias that go to inside layers. I'll have to get the schematic Edited July 23, 2019 by EkriirkE Quote Link to post Share on other sites
68kMLA Supporter trag Posted July 23, 2019 68kMLA Supporter Report Share Posted July 23, 2019 The 8530 and the Static RAM chips are available (or were). As long as you can save the IOP and are able to repair the traces, if should be fixable. Nice project. Quote Link to post Share on other sites
olePigeon Posted July 25, 2019 Report Share Posted July 25, 2019 (edited) I'm as jealous of your IIfx as I am of the monitor stand. I've been looking for that stand (plus the IIci sized one) for many, many years. Are there any markings on the stand? I thought it might be Kensington.

Yes, the stand has a sticker on it by Raduis - the other big player in Mac graphics. But nothing more identifying than that like a model Bonus underside shot showing reinforcements made in corners and under the top Quote Link to post Share on other sites
olePigeon Posted July 25, 2019 Report Share Posted July 25, 2019 @EkriirkE Oooooh, that helps a LOT! I never even knew who made it before today. Thanks! I always assumed it was Kensington because they made those kind of things back in the day. Although I'd imagine the stickers get lost all the time. I'm wondering if it was originally sold by Supermac. It would make sense to have both a Supermac monitor and a Radius branded stand because Radius eventually bought Supermac. So now I know they existed in the wild outside of advertisements. I've still never seen the IIci/IIcx/Quadra version in the wild, only in print. Thanks for the pictures. It goes without saying that if you decide to get rid of the stand, I'd be more than happy to trade/buy it. I'm in the South Bay. Quote Link to post Share on other sites
EkriirkE Posted July 26, 2019 Author Report Share Posted July 26, 2019 @olePigeon Glad I could help! Unfortunately this lot is still in Germany But the stand seems easy enough to make if you have access to any decent workshop. Mabe ask someone over at the TechShop if they still exist?

slomacuser Posted August 8, 2019 Report Share Posted August 8, 2019 I like that monitor stands too. Will probablly recreate one for IIcx and II. Here is the Radius ad from Macworld magazine And IIcx stand from SuperMac showroom Quote Link to post Share on other sites

They were a community machine shop in SJ/RWC, looks like they closed a couple years ago. You could have had one bent into shape from sheet metal there for you, the design is simple enough... @slomacuser Very cool! Edited August 8, 2019 by EkriirkE Quote Link to post Share on other sites
