Not yet, Garrett. I wondered if the MT-branded 24-pin TAG SRAM on my bad cache card might be the problem since MT-branded RAM is so often a failure point in 8-bit computing. I used the guide Kai shared to identify a replacement with the same pinout and installed them on my cache card...

I restored a Classic II about a year ago that exhibited the gray screen but no cursor. I wrote about my experience here, see if this might help at all. https://tinkerdifferent.com/threads/adventures-in-classic-ii-repair.1149/

Because you put in a known good board and the CC worked, that also rules out the large connector as a problem, something that I encountered in the past. Beyond @Mu0n‘s suggestion about vias, I’m not sure what else to try other than EGRET and/or sound chip replacement.

That did the trick. Thanks! (Sent from a MacBook2,1 running 10.7 and SeaLion - works like a charm!)

Works great on my MacBook2,1 running 10.7 Lion. Only saw one minor graphical glitch on the Quit dialog box where the bottom of the Quit, Cancel, and Save and Quit buttons are chopped off.

Cool, I’m going to follow this thread while I work on my Apple //e. Mine has rusty screws although the chassis, PSU, and logic board appear fine.

My IIci restoration project last summer also required a repair in that exact same area with the same chips. You can read about it at this thread here. I’m by no means an expert, but it wasn’t too daunting of a task. My IIci is purring like a champ.

I don’t see any active IIfx sales on FleaBay currently but my history over the last month shows non-functioning for parts only IIfx listings all in the $200-$300 range. I’d say our hobby has driven up the prices in recent years. And to think that back when NASA issued me the new IIfx in 1990 it...

Here is the same for US eBay buyers https://www.ebay.com/itm/353675714585?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=z85Zunj2Qd-&sssrc=2349624&ssuid=mmdlzm_0q_k&var=&widget_ver=artemis&media=COPY

For #MARCHintosh 2023 I performed the stereo mod to the analog board of my Color Classic Mystic. James Wages @JDW has an excellent tutorial on his YouTube channel. I salvaged the amplifier chip from a donor CC analog board and ordered the passives from Mouser. I also salvaged a matching 16...

I have not looked for a replacement jack yet. Perhaps @3lectr1c has some insights?

FWIW, I have not recapped my PowerBook 5300cs. I took mine completely apart for cleaning and inspection about a year ago. The electrolytic cap on the logic board looked fine (no bulging or cap juice) and the same with the cluster of caps on the DC board. I opted not to do a recap yet. The DC...

I recently restored a Black MacBook2,1 Mid 2007 sporting a 2.16 GHz Intel Core 2 Duo chip. Back in the day, this is the MacBook I really wanted, but since I had a White MacBook1,1 from 2006, I didn’t satisfy my urges back then. Now, I have a near mint condition Black MacBook that I...

Yes! I gave upon Twitter when it discontinued its API for TweetBot. Mastodon reminds me of Twitter in the early days, and I’m loving my test drive of Ivory by the makers of TweetBot. https://bitbang.social/@rikerjoe

I got a BlueSCSI v2 kit that I plan on assembling this weekend. Out of curiosity, if you had a choice between installing it in a Mystic Color Classic or Macintosh IIfx, which would you pick and why?

Thank you to everyone who volunteered to serve, and congratulations to the elected Board members. Let’s make tinkerdifferent.com even awesomer together!

Thanks for the links. I performed the steps and got the IIfx floppy to read existing disks but couldn't get it to write successfully. As I was troubleshooting, the drive made an awful sound then the motor stopped working. The eject mechanism still works fine. I suspect I might have shorted...

So far, I’ve had consistent behavior between internal BlueSCSIs and the external PiSCSI regarding termination, where I enable termination on the PiSCSI for all of my retro Macs except the IIsi. I recall back in the day the voodoo magic to get SCSI termination just right, then Don’t Touch It...

I had a similar problem with a Mac IIsi with an internal BlueSCSI and an external PiSCSI that I was able to resolve by turning off termination on the PiSCSI. A BlueSCSI in a IIsi requires external power (not enough is provided by the SCSI port itself) so I am assuming it is some weird...

Thanks for the suggestion. I found the zero track alignment procedure in the Dead Mac Scrolls, so I'll give it a shot next weekend and report how it goes.
