    Buzzz ADB I/O device recreation?

    I found this thread: https://68kmla.org/bb/index.php?threads/mac-se30-gpio.4427/ I'd love to know more about the ADB I/O device (photos? software?), especially since as ADB is a relatively simple protocol (PDF) and there are implementations of it on AVRs and the like... so it should probably be...

    Quadra 650 dead...but PSU works

    I recently got my hands on a Quadra 650, not in the best shape, but tantalum capacitors on the motherboard and no battery leakage! I replaced the PSU capacitors, and all was well, but then I left it unplugged for a couple of days and now it won't power on at all. I can get the PSU to start by...

    PowerBook Scuznet adaptor

    So in the main SCSI to Ethernet thread, I mentioned that I’d made a PB100 2.5” version. I have now (finally) received all the parts, assembled it and done some initial testing. IT WORKS! Next step is the 3D printed “base” so it can sit nicely inside the PowerBook, and testing that all the...

    Mini Quadra & AppleColo(u)r Display

    So in the 3D printed object thread, markyb86 made an excellent Quadra Pi zero case. I made a matching AppleColour RGB monitor designed to fit a small 640x480 LCD module The module has arrived and I have made it work! I also spent some time making a working Basilisk II image with a HyperCard...

    ESP8266 wireless without another computer

    So ages ago I looked into this and couldn't make it work: Recently I saw something on Hackaday which made me think: https://hackaday.com/2019/07/03/amiga-in-the-mist-gets-online-with-an-esp8266/ So I got a copy of the project: https://github.com/martin-ger/esp_slip_router (Had a bit of...

    slirp

    So a while back I was trying to make my old powerbook wireless with an esp8266. Turned out that when it said it did SLIP, it didn't actually do SLIP in the same way. That doesn't really matter anymore. What does matter is that it can become a serial bridge, and I can get a linux shell and...

    5500/225 & RTL8139 TCP/IP

    So... back at the parents' house over the holiday period and I'm playing about with my old 5500. I try to access the internet, but I'm only getting a 169 address... A few hours later, and various combinations of parts/software I have deduced the following: The 8139 card under both Mac OS...

    Recovering PB100 batteries

    Has anyone tried recovering a PB100 battery? There are a number of guides online regarding recovery of SLA bateries like the one the PB100 has... and having a look at the battery, it's pretty easy to pop the top & remove the caps to get to the cells. I realise these batteries are getting...

    5x0(c) CPU card differences

    Looking at this: http://hackaday.com/2016/08/22/ask-hackaday-calling-all-68k-experts/ I'm wondering if there's just a set of jumpers telling the Mac to look for an FPU or not... But I can't find pictures of the back of a 550c card to check if what look like jumpers between the LSI chip and the...

    Alphasmart SDK

    This is a bit of a long shot... But has anyone ever done Alphasmart SmartApplet development? I can't seem to find anything online about this, bar a few pages on the Renaissance Learning website, which seem to do little more than tell you how to update a few things. (The waybackmachine doesn't...

    SE/30 flyback in the UK

    Anyone know somewhere I can get a replacement SE/30 flyback transformer in the UK? There are a few available to me on eBay via. international shipping, but they're not cheap! Just want to exhaust all the options before I'm resigned to buying one from there. As an alternative, there do seem to...

    Pismo keeps asking me to shut down

    I know this isn't a mechanical problem, as I've gone so far as to unplug the power button to see what I can do here. I know the power button works, because it can boot the thing from cold. But every 5-10 seconds, the "Do you want to shut down" box pops up, as if I've just hit the power button...
