I'd love to be able to recreate the functionality of these chips in CPLD/FPGA form - so you could use them as replacements in Reloaded boards, or repairs. I'm envisioning something like this: https://www.tindie.com/products/furrtek/neo-d0-replacement/ in terms of footprint, although you could...

I know, I know, them's is fighting words! But, i stand by this method. Pics coming soon, will edit the thread when I have some. Ingredients: Knorr Beef Stock Pot x 2 500g Minced Beef - 10 or 12% fat - just not 20, or 5 - that's too fatty/lean respectively. One large red onion (for a sweeter...

I'll be making a run of boards in August/September for the SE, SE/30 and Classic Reloaded - however, i've just been made redundant so finances are a little tight until my severance pay comes in!

What logic board are you using in that? :)

Well, the latest email i sent to the creators of Sprint Layout said that 6+ layer support is 'coming soon' - so it's more plausible...

@max1zzz has them for the Plus, LC/LCII & LCIII and the IIcx is nearly ready too, i believe?

I am - i actually have one, kindly donated by a TD user.

THE FLYBACK HAS BEEN LOCATED! For some reason the bag it was in, had been put in the 4th floor kitchen/canteen/bar area of the office i work in...uhhh...why, i don't know. However, that means that fingers crossed, the Plus will be fixed soon!

Should work for any PCI PowerMac

Excellent guide, stickying this.

OK well, from a quick glance so far - Apple P/N 343S1027 is identical in pinout and function to the Ti SN74BCT2420 - Nubus Bus Transceiver, available at UTSource: https://www.utsource.net/itm/p/1008026.html The NuChip30, however? Made by Pinnacle Micro in Irvine, CA, by the looks of it. I...

That trace damage looks pretty grotty but it depends on the copper hiding underneath the rotten mask - @Branchus and @Mac84 might be able to assist with this.

Anyone can upload resources here - so feel free to upload it! :)

You could use the pinouts referenced in the BOMARC schematics to see if they line up with the pinouts of the TI offerings. If the pins are merely re-arranged, you could build an interposer of some description, like the castellated PLCC replacements they use on NeoGeo & JAMMA boards.

Might be time to rope in Porchy and Max for the reading of those as well. For the NuChip - I did send one with a broken leg to @jgrip for imaging - which might also come in handy, if it's an off the shelf ASIC like the BBU is.

Porchy / @Bolle / @max1zzz may be up to the task :)

Hi there! If you're after a replacement chip - UTSource carry these in stock for $30 each https://www.utsource.net/itm/p/11615479.html You can probably remove the chip and lose the LAN functionality - just needs to be removed carefully, with hot air.

Woo! Orders to fulfill! :D

Yep - PLCC is an acronym for Plastic Leaded Chip Carrier. I.e. square, legs on each side, can either be socketed, or soldered.

Good thing he's building a new one from that then ;)
