    Plastic fasteners on Classic analog board sleeve

    What is the direct replacement you have found? I'm just using 3M double sided adhesive. Appears to work well and didn't test as conductive but if there is something purpose built for this I'd rather go that route.
  2. I just finished recapping 3 Mac Classic logic boards. When starting them up, two displayed horizontal lines on boot (not garbled, just perfect ~4 pixel wide horizontal lines). When taking them back to the garage to clean them up I noticed that the ROM on the board I had just powered up felt warm. That prompted me to realize I made a silly mistake: I didn't notice there was an extra row of pins on the side of the ROM socket and for two of the boards I had the ROM in the wrong pins. I fixed the issue and tried to boot the boards. This time 2 of the three worked and the last one still had the same lines. By swapping ROMs across the boards and I was able to validate that one of the ROM chips itself was causing the problem. I'm not sure if the chip was ruined when it was plugged in to the wrong set of pins on the ROM socket, but I'm thinking probably not given that the other ROM chip is still working fine. I'm posting this as I've read a number of posts regarding these horizontal lines and none of them concluded on the issue. TL;DR: If your Macintosh Classic boots up with horizontal lines/bars either your ROM chip is defective or one of the traces going to the ROM socket is defective.

    @SE30_Neal How do you retrobrite?

    Modern PSU for the SE/30

    That is how I wired mine as well. The only downside though is I'm still hesitant to leave the computer plugged in when I'm not using it. If I had wired the PSU AC power to the physical switch I probably wouldn't think anything of it as turning the Mac off would mean it's off, full stop.

    Repair: AsanteTalk or MicroAsantePrint?

    Well, I just recapped it (two radial caps, a 2200uf and a 470uf) and no difference. The box is definitely doing something on both the LocalTalk and Ethernet side of things, it just doesn't seem to be bridging the two (except for one time). When I plug in power to the Asantetalk with everything else powered up, the Ethernet lights start to flash quickly and on the Mac that is connected via LocalTalk with the Chooser open, the cursor turns to the watch for a moment once the Asante finishes flashing. But the server I have on Ethertalk doesn't show up in the Chooser and another Mac connected via Ethertalk can't see the machine with the AsanteTalk.

    Repair: AsanteTalk or MicroAsantePrint?

    Well I may have spoken too soon. Looks like the box only works when all of the planets are in alignment. I've tried it since with a IIci and an LC II and no luck. It would be great if there was a modern alternative to this box. Looks like there were some investigations but nothing came of it.

    @Johnnya101 thanks! for your next compact Mac shell done in a turkey bag, how many bottles of cream developer do you think you'll need?

    Repair: AsanteTalk or MicroAsantePrint?

    OK - NEVER MIND. It's working. I don't know why, or how. Maybe it just needs a lot longer than I thought to boot and register. I finished that post above, went back to try to reset the PRAM on my Duo (another post indicated their AsanteTalk started working after they did that) and low and behold in the Chooser, there was my AppleShare server. nbplkup now also shows the AsanteTalk. I feel a bit bad now that I bent the metal case opening it the other day but I guess it will just sit under a desk anyways. (Well on top of the desk for easy access to the power cable.) pi@raspberrypi:~ $ nbplkup AppleServer:AFPServer 65280.17:128 AppleServer:netatalk 65280.17:4 AppleServer:Workstation 65280.17:4 AsantéTalk 94A8C686:Asant?Talk 65485.175:252 :ARA - Client-Only 65485.176:2 <Unnamed>: Macintosh PowerBook 65485.176:252

    Repair: AsanteTalk or MicroAsantePrint?

    When I was searching for AsanteTalk troubleshooting, it appears that the AsanteTalk registers itself on the AppleTalk network. Here's an excerpt from another thread here: $ nbplkup gateway:ADSP 40215.94:128 10.1.3.1:IPADDRESS 40215.94:72 10.1.3.1:IPGATEWAY 40215.94:72 gateway:netatalk 40215.94:4 gateway:Workstation 40215.94:4 EVO:DceDspRpc DynEpt 638.1 41384.136:136 EVO:DceDspRpc DynEpt 114.1 41384.136:129 EVO:DceDspRpc Endpoint Mapper 41384.136:130 EVO:AFPServer 41384.136:131 083D86B6F0E990040330A5CA083D@EVO:Microsoft¨ Windows 2000ª Prt 44318.148:2 083D86B6F0E990040330A5CA083D@EVO:Microsoft¨ Windows 2000ª Rtr 43497.215:2 Asant?Talk 94AFE828:AsantTalk 40000.15:252 10.1.3.2:IPADDRESS 40000.16:72 porter:Macintosh Classic 40000.16:253 This time, I tried plugging it into my Duo 230 which is running System 7.5.x The Duo seemed to recognize that there was an AppleTalk network connected as when the Localtalk box was plugged it a dialog box came up and indicated "Your AppleTalk network is ready for use" but still no joy (or AppleShare server). The AsanteTalk Ethernet lights keep blinking away showing there is activity. The LocalTalk network seems to be recognized by the Duo, but there isn't any bridging of the two going on and 'nbplkup' still doesn't show the AsanteTalk box. I've unplugged it and plugged it back in multiple times (and tried a different power adapter.)

    Repair: AsanteTalk or MicroAsantePrint?

    No zones are configured. My other Macs can see my netatalk server. I tried the power up sequence you noted multiple times without success. From what I read the Asante should still register itself on the Ethertalk side of the network which it doesn't seem to be doing. I think there is a problem with the device itself unfortunately.

    Repair: AsanteTalk or MicroAsantePrint?

    Resurrecting this old thread - I have an AsanteTalk box that I have never been able to get working. All of the lights flash like they should (solid link) when connected to Ethernet but it never seems to work. I have observed the power up sequence and I recently installed netatalk on a raspberry Pi to have an AppleShare server available and that allowed me to run nbplkup to see what shows up on EtherTalk. All of my Ethernet equipped Macs show up but the Asante never does. I have tried different switches and most recently an EN104tp 10 base t hub. I pulled it it apart and was thinking of changing the capacitors, just because but otherwise I think this unit just simply doesn't work. Anybody have any similar, seeming dead (but still lighting up) AsanteTalk boxes?

    A9M0106 Cleaning + Retr0brite

    AWESOME WORK!! This is timely as I bought some yellowed Macs and monitors that I would like to retrobrite. A few questions: 1) You said no brushing but just to put the parts in the bag with the developer. How much cream did you use? Was it fully submerged or just covered? 2) You say to "soak it". Is that in the sun, or in warm water? There is a lot of recent discussion indicating that heat may be as important as UV light in the process and some guys are using sous vide circulators. 3) In a prior thread, you painted on the cream onto an SE30 and then put it in the sun. It looked like that was on a cold day (snow on the ground). I guess temperature didn't make a difference for you? If you were doing it again, how would you retrobrite the SE30? Have you found any zip loc bags big enough for a compact Mac? i bought two bottles of 40 volume developer and am just debating buying a sous vide circulator or a UV light.

    $30 LCII from eBay

    Sorry. I just reread what I wrote. I meant pliers. Not a screwdriver, definitely not a screw driver. I twist it clockwise then counterclockwise (ie rotating) but just literally by fractions of a hair at first and then progrsssively more. I think the pads are strongest laterally and that's the direction force is applied by doing it this way. Ive read with hot air there is a risk the cap could blow and you run the risk of making other nearby components too hot.

    $30 LCII from eBay

    I know everybody has their own style but for a board with corroded leaky caps I have had way more luck with gently pushing down on the old caps and using a screwdriver to twist a little bit left then right and back and forth probably 50 times and then the cap comes off at the legs. I tried two soldering irons, soldering tweezers, even ChipQuik but like you said the cap goo makes it very difficult to heat up the old solder. At the same time, the cap goo makes the capacitor legs very brittle and prone to breaking off. Since I started doing this I haven't lifted a single pad (prob 15+ machines) and it takes about 1/20 of the time.

    J1 connector (Plus analog board)

    Is there not a part number somewhere on the connector (either end)? I found the molex part number for the analog to logic board connector by reading the ultra tiny type on that molex connector.
