The last version of MacSSH can connect over the SSH2 protocol which is more or less mandatory today. But it does not support current strong cyphers like ed25519. While this is still way more secure than telnet, I could not connect to any of my Linux machines with it. As I said - Belt suspenders...

To answer @dan.dem's question. I've not been able to get the PC Card extensions working under MacOS 8 or 8.1 although I have tried on a 68k Performa 630 and not a PPC 6100. I had to switch  back to System 7.5.5 for the PC Card functionality although 8.1 did not display any other issues and...

@cofford It is true, Switches provide some degree if isolation and may prevent casual listeners. If there is anything out in your network actively sniffing passwords,  then Switch isolation does not prevent anything. For example - saturating the Switches throughput might just let it fall back...

This is a valid setup for sure. Altough would not recommend using telnet even in an internal network! Usually there are many non-trusted devices on the network, that are able to see your unencrypted passwords. Think about Smartphones, TVs etc... 68040 Macs can connect to modern SSH servers...

Regarding the boot from Rom issue. Mine also would not do that after recapping and repair. Clearing the PRAM on boot (comand+option+p+r) made it work again! I would suggest to disconnect the HD first, then reset the PRAM and then try to boot from ROM. Let us know what happens!

Same situation here - and same Idea about putting the SDCard behind the Security Lock hole. Cannot get it to work either :(

I also recently had problems with a Classic AB (See this thread) Short version, it turned out that the PP1 potentiometer was oxidized and did no work anymore, so I still had low voltages even after I replaced most of the parts you also did. Voltage a bit too low gave me a wobbly screen. Even...

So its a 220 Ohm pot - thank you for the information. I'll order a similar looking one, and if need be, I can always extend the leads and solder it on "free-floating" or fixed with hot glue. But what do yo mean by adjusting from the bottom? In my case I had to reach through and around the CRT...

@bibilit Nice one. That brings up memories of me doing a similar thing with a G3 iMac that was making an incredible loud high pitched noise. Found the source and glued it down with epoxy - that fixed the issue. I had completely forgot about that :)

Hi! Following the recent completion of my Mac Classic renovation I've continued to Software. I am looking for a Gopher client that works on System 7.1 (with Thread Manager) on a 68000 machine. TurboGopher is an obvious choice but on the Classic it crashes with an Error 2 just after the...

@blindowl Too late ;-) - I just wanted to tell you about the localization problem. I hit the same thing yesterday, but found the solution somewhere on the web before coming here. Were you able reach any speed higher than 9600? I'm too stuck at this rate on my Mac Classic. This is true for PPP...

Reading this I think your Classic Mac Repair skill are more advanced than mine. But maybe I can be of help still ;-) I had a wobbly screen problem with a Mac Classic recently (connected to disk drive activity). Replacing all the caps, some diodes and the QP1 optocoupler did not fix the issue...

So applying a generous amount of contact cleaner fixed the problem. The potentiometer seems o work as it should now! This almost finishes this Classic's restauration. The only thing left to do, is to finally figure out how to make the SDcard extension cord working for the SCSI2SD (as in this...

OK thank you. I will take the pot out and see if I can find anything about its values and replace or clean it. The story will continue after that ;-)

Congratulations! You saved another one :) And as I wrote in the other thread - I'm still trying to figure out some things with my Classic's AB, altough the Machine itself is not working as it should!

Yeah, that has been my first guess too. But it really feels like peaking a tuned circuit. I could easily tell the maximum by just listening to the RPMs of the fan. Is there any information about the PP1 potentiometer? Its range etc? It would be easy to replace and test of course. Or is there...

Yes, but what about the fact that I had to "tune in" the maximum voltage? It is not like described in the Classic Mac Repair Notes. Turning  PP1 to the left decreased the voltage, as did turning it to the right. There was a sharp maximum in the middle with the voltages written above. For me...

No, ferrite cores also do not help :(

Thank you for the link. As I read it, it means some cables work, some don't  - pity :( I will try to clap on some ferrite cores. It may reduce electromagnetic interference, or it might add to the cables capacity an make everything even worse. I will try it anyway and report.

Hi! I have a SCSI2SD 5.0a set up in a Mac Classic and it works fine so far. Now I would like to be able to easily reach the SD-Card for swapping it out/making backups etc. So I got a SD-Card extension cord and wanted to put it behind the Classic's lock slot in the back. But unfortunately it...
