Same here, I'll have 2 working, well, 1 because the SE/30 won't have a good hard drive and SCSI2SDs are super expensive for me.

 

[Verault]

its true they are expensive. I happened to have a spare 500MB scsi hdd from a scrapped powermac 7100/80 in my SE

 

[Retro Rider]

I've been looking for CF to SCSI adapters because I already have some CF cards and I fell like they would be cheap, but I can't find any

 

[Verault]

they pop up from time to time, just not common.. which is weird to me they should be more common. I just learned they have MFM/RLL to SD devices which is amazing, why arent there cheap scsi to sd or cf on ebay?

 

[Retro Rider]

Where do you find them though? It's super weird that they're so rare, most stuff like this wouldn't be (at least I would think)

I bought the SE "working" off ebay 2 years ago with a bad 20mb scsi harddrive. I upgraded all the roms and bought a super drive just for ease of use. I also upgraded to 4MB of ram (which was an undertaking since I didnt know there was a jumper/trace to set the ram amount at the time.   the classic I got maybe a month ago for $25.00 knowing it was broken. I figured the hard drive CRT and floppy at least would be worth that if it was dead.

The Plus I paif $50 for last fall. It worked but when I got it home found the battery compartment/Analog board and chassis very rusty. In cleaning the rust and corrosion something failed on the analog board so Im still working on fixing that (it has the horizontal line like yours)

Supply & demand.

SCSI is effectively dead except for a few specialty applications and vintage enthusiasts.

There just isn't sufficient demand for these items for the price to come down or become more widely available.

I LOVE SCSI! Always have! IDE was inferior. Bus speeds, drive speeds, spin rates! All of it! I remember in 1998 I had to install a SCSI scanner which made these incredibly detailed images for the time which were about 300MB files when done for a pharma company. Really good stuff.

Could these 2 be part of the issue?

They were the only ones that looked kinda off and there was a weird smell coming from that area

 

[techknight]

that corrosion is caused by the leakage of the 2 caps nearby. 

 

[Retro Rider]

Looks like it might be that whole area of capacitors because I found these 2 corroded things (image). Might need to get someone to recap all of those and get new replacements for the corroded parts

 

[Verault]

yes, those caps are bad, and if they are most likely others are bad too. Those are Diodes (the things in black) they could be faulty but I would replace all the caps first. The smell is the electrolyte that oozed from the capacitors. That ooze will corrode ALL the exposed metal and traces if not cleaned up/.

Would this work with a 68k Macintosh? I know it says IDE to CF, but it doesn't have that one hole out like usual ide connectors

 

[Verault]

I have those for my old ibm compatibles.. they work but only IDE systems. you need the SCSI to CF or sd card. 50 pin to work with a compact mac.
