README
README.mdIBX ][ Hardware
IBX ][ is an information barrier setup for nuclear warhead verification with an Apple II (Details). This repository contains schematics and layout files for two custom Apple II peripheral cards.
The KiCad files use the Apple ][ Edge Connector Template, best place it inside the directory as (Apple2_Bus).
ADC Board
Apple II peripheral card for A/D conversion of signals from radiation detectors (scintillator/photo multiplier combination). The card includes all necessary parts - pre-amplifier, amplification & pulse shaping, peak-detect and hold circuit, ADC timing circuit. The current revision is improved to use full +12V/-12V components all the way to the ADC. Previous versions included 8 LEDs that can be toggled by writing to a specific Apple II memory location, but these have been removed now.

Address scheme (has to be offset by address of card slot, eg. 49344 for Slot 4):
| Address | R/W | Function |
|---|---|---|
| 01 | (Read) | Reset trigger circuit, make it ready for a new incoming pulse |
| 02 | (Read) | Read low byte of ADC value |
| 03 | (Read) | Read high byte of ADC value |
| 04 | (Read) | Read status buffer for ADC |
HV Board
Apple II peripheral card to provide high voltage supply to devices (e.g. Photo Multiplier tubes). The voltage is adjustable by writing an 8bit value to a memory address. It produces a voltage from 0-5V depending on this value, which gets converted into highvoltage by a CAEN 7505P module.

Questions
How big is the Adcboard PCB?
It measures 184 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Adcboard use?
126 parts, built around the 74HCT244D, LM6172IM, 74HCT00D and 74HCT04D. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Adcboard KiCad files?
From the nuclearfutureslab/ibxII-hardware repository on GitHub, at the commit this page was made from: the board is adcboard/adcboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Adcboard design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
