Hi 68kPlus, I went a step further and created a design that supports both 3.7V 14500 and 1.5V Alkaline/Lithium batteries. Using a small custom voltage regulator the output voltage remains 4.5V (which is the original battery voltage), regardless of the battery type (1.5V -> 4.5V) I there is a...

Dear all, For those who are interested, I have a few (unpopulated) SE/SE30 analog boards left from my SE analogboard recreation project. https://airtalk.shop/product/macintosh-se-and-se-30-analog-board-recreation-630-0147-c These boards are electrically fully functional but have one...

Yes. See the GIT readme for the building manual. When I have more time (beginning next year) I will may sell them pre-assembled. Do you think this will be an addition to the community?

Dear friends, Just for those who are interested; I designed a low cost 3D-printable drop-in replacement for the "SW1" powerswitch for the Macintosh 128k/512k/Plus. https://github.com/daanvdl/mac_plus_sw1 Have fun! Regards, Daan

Dear friends, Just for those who are interested; I designed a low cost 3D-printable drop-in replacement for the "CAPETRONIC DS 1011"/"815-0727-B" batteryholder for the Macintosh 128k/512k/Plus. This replacement batterysocket is based on a 14500 (AA-size) 3.7V rechargeable battery which is...

@Dogmander Currently I don’t have the plan of recreating the Classic Analog Board, but never say never:) Recreating boards is not a “few days” job so I need have (a lot of) time left, which I currently don’t have. Currently I don’t have a Classic I/II AB. If there is somebody who want to “give...

A short update from my side: The first run of the BETA boards just arrived. And, they look stunning!:love: The first batch has been send out for deploying and testing. Will keep you posted!

Hi Julian, I will keep you informed of the progress here. Drawing the schematics and the tracks took more time than hoped. This was very time consuming. I am currently do the final checks before having the BETA boards etched after which they will be deployed and tested. Regards, Daan

No problem! I currently do have enough testers. Will keep you posted;-)

Initially this will be a 100% 1:1 reproduction. Apart from 'Q12' (for which there are still alternatives) there will be more parts that are no longer produced, such as transformers, flyback, battery housing, linearity coil, adjuctable width coil, power switch, etc. In many cases, most parts will...

Best friends, Due to aging and battery leakage, we can condemn more and more boards to death, unfortunately. That's why I decided to recreate the INTERNATIONAL analog board (revision 820-0107-D). Especially because this includes 3 models: 128k/512k/Plus, and intermediate models. I realize that...

Let me know if I can facilitate something

Do you always connect multiple Macs in a network, then maybe more. My suggestion is always 2, or equivalent to the LocalTalk concurrent network connected Macs. I do have 1 diy kit left, but I suggest the PRO because of the look and feel.

I am not sure about your Atari, but always a nice thing to try;-) I generally use them between two of or more 68k Macs and occasionally to a Mini vMac instance. Remember it is LocalTalk, so don’t expect Ethernet speeds;-) Don’t forget the printer/serial cables if you don’t have them yet!

Yes, indeed. You can transfer files from Mini vMac by joining the LocalTalk network wirelessly😬 I have a few left, go for the PRO version if you want a complete (non-DIY) product. https://www.Airtalk.shop

Are you testing with a BlueSCSI?

Will it recognize the disks at all? Could also be a termination issue. When it is passive termination: check TRM power.

sounds like a RTC issue
