Re: [M100] MiSTer FPGA Core
The DE-10 Nano also has an ARM CPU which handles I/O and provides a nice interface for USB and (I think) the HDMI frame buffer. This should save a lot of effort when it comes to I/O mapping, since the ARM software can handle the keyboard and storage interface (for backing up RAM in between sessions and the presumed TPDD and REX flash storage interfaces.)

Re: [M100] MiSTer FPGA Core
The MiSTer is based on the Terasic DE-10 nano, which is based on a Cyclone 5. The board has 1GB of DDR3 RAM, but most MiSTers are build with an add-on board containing 32 or 128 (or more) MB of SDRAM so you don't have to deal with DDR. -Josh On Sun, Apr 19, 2020 at 8:34 PM Ken Pettit wrote: > I have most of one.

Re: [M100] MiSTer FPGA Core
I have most of one. It has been quite some time since I worked on it, but I had it running a modified version of the M100 ROM. It was working on an Actel FPGA at the time sometime in the 2009 - 2010 timeframe, but I believe that FPGA is now obsolete. But it is mostly just Verilog / VHDL code that could be ported to any FPGA. When I say modified ROM, the modifications were because I had extended the 8085 CPU with 24- bit registers and relative branches. I had it running in simulation a few months back. From what I recall, I had modules for the LCD, keyboard, 80155, etc. What type of FPGA are you interested in using? I typically use Xilinx these days.

What I can't find, yet, is documentation on the software that comes pre-loaded and how to interface with them. It looks like there are some solder points for two GPIO pins on the board: pins 12 and 2. I'm hoping that these things come with enough documentation for me to figure out to program them and tie them into a TTL serial device. I have plans to build at least two microcomputers (both running CP/M using two different emulators) and a stand-alone terminal for things like this project.

Thanks, Steve. I have been using my own terminal program with my Altair emulators for a long time, and it's always nice to find new uses.

So they are all standard VT100 codes? That’s good to know. I know a couple of guys who produce GeoffG terminal boards for an Altair clone, and I may have a more ready supply than the Tindie guy. So I *may* be able to get a supply of kits and have the PICs programmed with the additional VT100 codes. David, the guy who customized the firmware for the Altairduino, has already modded the firmware to use a USB keyboard. I’ll add those codes to my test suite and see if David’s firmware supports them.

How funny. I’ve been re-writing Star Trek to get rid of some bugs and make it work more reliably on the 100 (and CP/M.) I’ll have to add a DVI mode, too. Is there any way to detect the screen size?

[M100] BCR serial TTL hack
http://bitchin100.com/wiki/index.php?title=BCR_TTL_SERIAL_HACK I've documented the information around using the BCR port as a half duplex TTL serial port. The solution for M100 is to solder in a single wire on the backside of the PCB. I expect a similar solution exists for T102 and other machines. I've included the schematic and layout change as well as my code for demonstrating M100 <--> M100 transmission at 57600 using BCR port. Also, my code for very fast 115600 and 128000 baud transmission is there for reference. Steve
