I suspect for the mating board connector there is an equivalent plated through connector. There are so many of these thing s these days there almost has to be one. As to speed, I looked at the Pi, it runs at 700MHz, this one is at 1GHz. At that speed assembler driven ARM code should have absolutely no trouble interfacing the S100 bus. A high level language, possibly. It may require data latches on the S100 bus, but I don’t see why one would not use ARM assembler for key interfaces.

Subject: Re: [N8VEM-S100:5018] An ARM CPU on the S100 bus That mating board has SMT connector - so I don't see where you make sense here and John that sample mating board has not through hole connectors so I don't see how you would connect it. I have looked at several boards like this and they base board brings out connection to headers parallel to the board that allows small modules to plug into it. They generally don't have pins perpendicular to the base board so it is not friendly to mounting to another bigger board. You can get the connectors like on the base board to mount on the S100 board but they are SMT connectors not thru hole because the pin spacing is much smaller than thru hole. Look carefully at the specifications of the module and the base board.

Subject: Re: [N8VEM-S100:5012] An ARM CPU on the S100 bus Hi John, The board you are suggesting will probably be a challenge as those connectors I believe only come in SMT style and the alignment of them are very tricky so I don't think you would be able to hand solder them. Dave

They offer a mini-board with two 100 pin connectors on the back that would make the placement on an S100 board very nice. The S100 board would be modeled after one of their "TS-Sockets" and should in theory allow one to use a number of their "Computer on Module boards". They supply a free IDE programming interface but somebody told me programming the I/O control lines is not easy. There are 121 of them. Clearly plenty to control the critical S100 lines for other S100 board I/O data etc.
An alternative I've been looking at is the European Olimex line, for example their A13 https://www.olimex.com/Products/SOM/A13/A13-SOM-256/
The advantage of them is they are more "hobby" oriented and supply much more information. The down side is their boards don’t have the connectors on the back. The could be placed upside-down (not great) or perhaps removed and re-soldered.
Anyway early in the process, I have currently started on an 80486 S100 board which I will do first.
Everybody out there, please feel free to supply suggestions as to "modern" CPU board you would like to see on the S100 bus. If a cell phone can contain a powerful computer, the is no reason our S100 boards cannot be one!

These System-On-Module (SoM) packages offer some interesting capabilities.
Ethernet / wireless support and integration on the S-100 card being a BIG Plus.
Connectivity is replacing most storage media for data/program transfers, such a board could serve the role as a surrogate for other S-100 boards.
Depending on implementation, an ARM based S-100 board (Linux) could also eliminate the need fir a separate PC to address -- uploads, interfacing, etc.
Intel's migration to NUC, now in their 4th generation, shows another paradigm shift and options. It could sit inside a S-100 case -- or attached to back of monitor (VESA), being a super-smart terminal/workstation.
