@Androda makes flat flex cables for stuff, he may be amenable to creating something :)

Honestly, the 2SC5299 datasheets i've seen specifically refer to it as a HOT transistor - the ISC one, specifically.

Any PCI NIC based on the DEC 21140 NIC chip should work, as that's what was on the official Apple add in PCI network card.

Stickied this thread - great work Max!

Did you look at the memory chart i linked above to find other 4Mx4 DRAM's in SOP? :)

Try www.utsource.com

Paging @techknight to the thread, as he's the CRT god 😂

Cory? Who's cory? ;)

Tindie is great for maker space stuff - the front end and web store is already there. You're also welcome to apply to the TD Trading post for your own section, if you'd like :)

Thing is though - he's needing the SOP parts, the CJ are the SOJ's - which may not fit in the footprint. This chart has a few more bits on than the PDF you linked: https://ardent-tool.com/memory/Chip_Conversion.html

And here's a seller of these panels: https://www.aliexpress.com/item/1005003367936381.html

You can download the Sprint layout file from the Macintosh Classic Reloaded GitHub and use the 'test' function in the demo version of Sprint, to find where the trace goes.

Yes, those have, in fact, also been used in SE/30 boards, as seen here: Get a pair of them. Check under them for trace rot/grot as well, while you have the originals out - might as well put in some dual wipe sockets, too :)

Would it be possible for you to add a BOM/PnP file usable for a board house like JLCPCB? :)

Are the 68HC24's a pain to get hold of? I know UTSource supplies them in bulk, but not sure if they're going to be available for long elsewhere - looks like they were EOL'ed in '99?

Love it - i'll take two! 😂

I need at least one of these - excellent work, looks almost factory!

Pics here pls :p
