The diodes and bodges look good.

I forgot to put this in my last post. In your third photo, some of those traces are definitely gone and need to be replaced, but some are probably still good under the corrosion and lifted solder mask. You can carefully use an x-acto knife to scrape the solder mask off. If you can scrape off the...

I'm glad to hear you are making progress. Do you have more photos of the damaged area of the board? In your third pic there are definitely a couple rotted vias. Have you checked what they connect to, and come up with a plan to repair those? If the via just goes straight through the board and...

Did you find one to purchase, or are you going to build your own? Last I heard there is not a known source for the clip that clips over the 68000 on the Classic, it is a newer package type than the 68000 used in the Plus.

Eek yeah, definitely fixable but it will be tedious. How are you going to approach the diode repair, are you going to glue the parts in place and then bodge from there?

Is that the worst damage on the board? Are the diode pads still there, or did they come off entirely?

I had a IIsi PSU I recapped, it had a fair bit of corrosion that I left alone when I did the recap. It worked for a while, then just shut off mid-use and wouldn't stay running after that. I took it back apart, scraped a bunch of corrosion and added solder to the bare copper. It looks a lot...

I ultimately wrote this board off and repaired another IIsi board I had. I did a bunch of work to this one and could never get rid of the death chime. I replaced the onboard RAM with known good chips, replaced all the ALS245s, beeped out all the traces going to/from the RAM and ALS245s. A...

My BlueSCSI v2 works great, for some reason the accelerated Plus just does not like my v1.1. I used the same SD card in both just to rule out card incompatibility.

@MrPickles2169, do you have a Floppy EMU? @JDW is having trouble with his accelerated IIci (DayStar accelerator) not being able to read 400k or 800k floppies or images using his Floppy EMU. I am curious if it is a problem with accelerated IIci's in general, or unique to his machine/accelerator.

A few months back I picked up a DayStar PowerCache 50mhz card for $250, plus $25 for the Mac II adapter the guy had. Granted it is not a Diimo, but it's a data point. I don't know if the Diimo cards are more desirable. You could also check eBay sold auctions.

In both my accelerated Plus and accelerated SE my FloppyEMU will not work in HD20 mode, I get the same "READ STATE CHANGED" error. From what I have read the FloppyEMU does not work well with accelerated Macs.

I have a CC that I suspect has a bad CUDA chip. I found the list below of CUDA variations from an old post. Does anyone know if any of these are compatible with the CC? It appears the CC is the only machine that uses the 341S0417. From what I can find online 341S0788 seems to be used in...

Thanks, I'll try those suggestions.

Unfortunately the only external SCSI drive I have is the BlueSCSI, all my spinning platter drives are internal, and I don't have any sort of adapter or enclosure to adapt the 50 pin dive to the DB25 port on the Plus. That's good to know about the SCSI2SD and potential ZuluSCSI working with...

I recently installed my Performer clone accelerator into my Plus and have found it seems to be incompatible with my BlueSCSI v1.1. Does anyone know if there are any SCSI emulators that work with an accelerated Plus? I know the Plus's SCSI implementation is a bit non-standard so they have...

It's always interesting to hear people's real-world stories about these old machines.

Another alternative until the WarpSE is completed is a MicroMac Performer clone. If you are into tinkering it's a fun project, I did a write-up (link) to my build.

Unfortunately I don't have a pic of the accelerator compared to stock, and somehow my Speedometer records file became corrupted, so I don't have easy access to that info without re-running the tests. The increase was significant though. The pic below is from an accelerator benchmark thread on...

Well I spoke too soon, shortly after that May 2nd post the machine began the death chime again and would not boot. I put it on the back burner since I did not have time to work on it. I decided to work on it some more recently, I replaced the ALS245 chips with new chips from DigiKey, there is...
