LocalTalk and OSX? 🤤

I can recommend the Radeon 7000: https://68kmla.org/bb/index.php?threads/driving-a-23“-dvi-cinema-display-from-a-powermac-8500.43187/

Good to know!

That‘s the address bus with its 32 bits/pins numbered 0…31

Go and start coding 😉

I can confirm A/UX already works with BlueSCSI and Macintosh II series computers like the SE/30. A/UX‘s complicated startup procedure is due to the fact that the Macintosh ROM was not intended to load anything else than a Macintosh System file on a HFS volume. The A/UX kernel however is on an...

I think you can convert it to vga using a simple circuit

I think it‘s a PCPC video card with 9-Pin TTL video connector. This one is similar: https://www.ebay.ch/itm/154195765446?mkcid=16&mkevt=1&mkrid=5222-175126-2357-0&ssspo=tWt0jM94Q9W&sssrc=2349624&ssuid=e3-7ygrpska&var=&widget_ver=artemis&media=COPY

Appears to be a normal NuBus card… I can‘t see any reason why this would not work in an 800. Do you have higher resolution images?

There is a nice museum here in Switzerland: https://enter.ch/ They also have Macs, a couple of Lisas and even an original Apple 1! Definitely worth a visit!

Any ROM SIMM working on a stock board will work in a replica board. (I can confirm that both the stock and Rominator II SIMMs will work) However, if you remove the PLCC chips from any ROM SIMM and put them into the replica’s PLCC sockets (which don‘t exist on the stock logic board), they will...

Press the ⌘ and the V keys on your keyboard at the same time. It‘s the same keyboard shortcut as if you would paste some text from the clipboard.

Try booting into verbose mode by pressing and holding „cmd v“ during the boot chime. What‘s the last message you see?

Check Inside AppleTalk Btw. you can swap pin 1 and 2.. It doesn‘t make a difference due to the encoding LocalTalk uses.

My Studio Display is also green-ish when connected to a Quadra 700.. I believe it’s somehow related to ’sync on green’ . There is a System Extension made for the Apple Basic Color Monitor that can solve this.

My Mac Plus sounds similar when no logic board is connected… Check Larry Pina‘s Dead Mac Scrolls which is a vital source of information when repairing early Macs

I think you should be able to boot System 6 with no SIMMs installed.. If you have SIMMs installed, they need to be identical and all four sockets must be populated. To boot System 7, you need at least 2MB, so at least one additional Megabyte needs to be installed in the sockets.

It‘s a bit hard to see in the video, but did you also recap that tiny daughter board inside the PSU? Maybe there is a short somewhere, causing the PSU to shut itself off. From what I can see your EGRET and therefore also the 5VTrickle from the PSU are working properly. There is a schematic...

Today‘s work… Just needs new RAM, ROM and CAS PAL chips!

What about Classic ROMs?
