not "dumb questions" at all. everybody has to start somewhere. couple years ago, i was in the same boat you are... trying to decipher how to do all these things with 3rd party firmwares. it does take some time to wade through these waters, but they're really not that deep.
- Simultaneous key presses - meaning key roll over? how many keys pressed at the same time & still register. USB default is 6 which is more than enough, unless you're laying on top of your keyboard.....
- macros are supported, not sure if they are configurable in the web configurator, i did see macro in the action dropdown on the code edit tab. i don't use them, so i'm probably not the best one to ask.
- actually, if you want to go that route... web configurator, you certainly can, saves a lot of headaches... you'll just need a flasher to get the hex file onto the micro.

- pick "IBM4704-USB Converter rev.1 for Alps 102-key" from the dropdown (it's important you use rev.1, rev.2 will not work with your controller)
![IBM 4704 Pingmaster DIY controller question 214634-0](https://geekhack.org/index.php?PHPSESSID=qjh23vki8dciqsiuhgastudsgmtbkh6c&action=dlattach;topic=99757.0;attach=214635;image)
the reason this is important is the
rev.1 is a ATMega32u4, same as your controller.the rev.2 is a ATMega32u
2, not the same & won't work.
from Hasu's TMK converter thread...
TMK converters translate various old keyboard protocol into USB so that you can use the keyobard with modern computer.
How to flash firmware
Current converters(rev.2) use ATMega32u2(while rev.1 used ATMega32u4). You will have to select microcontroller in flash tool like Atmel FLIP or dfu-programmer.
To turn into flash mode press tiny button on converter PCB.
See this for detail: https://github.com/tmk/tmk_keyboard/wiki#flash-firmware
the only flasher i have experience with other than teensy is Atmel FLIP, very easy, follow link above for instructions & download
so, finish configuring your keymap & download your hex file. then download & install Atmel FLIP, flash your controller, then all you have to do is wire up the cable & connect it to the pingmaster (if you haven't already)
apologies for the extra stuff earlier, i didn't know hasu had web configurators for all of his different converters. the only one i knew of was the adb-to-usb configurator. plus, i've always done it the hard way.... i guess....
i still recommend you learn as much as you can of the info from the other sources, will help you understand how everything works together, but i can understand being overwhelmed & frustrated about not getting your 1st "custom" board quickly.
hang in there, you'll get it.
