Yes it seems that way but it can be verified with other ID. But as a starting point it is a good indication. Could you create a list of the machines that have so far reported 135?.

I think a variant on SWIOSCAN.BAS could be added to the reverse engineering tools that would detect pull-down, pull-up or floating bus.

I only documented the Mitsubishi ML-8000, Sanyo MPC-2 and Sanyo MPC-3.

I am looking for the NMS8250/16 BIOS (Spanish). I don't have the machine myself, but I need this to get my USB keyboard interface working with this machine. The keyboard layout between a NMS8250/16 and a Spanish USB keyboard seems to be very different. For US, German and French not much translation was required. Thanks!

I'm going to try to recreate the EMC-PB3605 PAL module for the Toshiba HX-10 because there are more than a few people that have issues with it and you can't find them.

The only issue I'm having is identifying L1 and L2.

L1 (green) 12pH +5% Inductor
L2 (blue) 22pH +5% Inductor.
Does that look right?

To my eyes the 4th band looks more silver than gold, so it would mean +/-10% tolerance.

Hi, I have a Talent DPC300 and I could dump the ROM if it is still necessary. Just let me know. I have DPC200A too.

Hi CASDuino, how are you progressing? Really curious! Will you use LVA510 on your redesign or are you considering alternative solutions (as LVA510 are not easily available).
