Pinout & Chip Analyzer / IC Quick-Finder
Interactive DIP and PLCC chip visualizer featuring signal direction indicators, bus group highlighting, power/ground rail flags, clickable oscilloscope trace popups, and datasheet links across 76 classic CPUs (6510, 6502, Z80, 6809E, 68000), custom silicon (SID, VIC-II, CIA, Agnus, Paula, ANTIC, POKEY, ULA, 40010), PALs/GALs/PLAs (82S100), DRAM/SRAM, and 74/4000-series logic.
Core Capabilities & Coverage
- Colour-coded DIP-14 to DIP-64 and PLCC-44/68/84 package diagrams with pin-1 notch orientation markers.
- Signal direction indicators (Input, Output, Bi-Directional Tri-State, Active-Low bar notation) and bus group pills (Address, Data, Control, Clock, Analog, Power/GND).
- One-click Oscilloscope Waveform Triggers on clock, reset, chip-select, and bus pins comparing healthy signals against common fault states.
- Bi-directional Machine Hub cross-references showing every retro computer or console mainboard that uses the selected IC.
Step-by-Step Workbench Workflow
-
1
Select Chip Variant or Filter by Machine Hub
Use the category pills (CPUs & MPUs, Sound & Video, Support & Peripheral, Memory, 74-Series Logic, 4000-Series CMOS) or the Machine Hub dropdown to isolate chips for your target system (e.g., Commodore 64, ZX Spectrum, Amiga, Dragon 32/64).
-
2
Search Pin Names, Part Numbers & Aliases
Type a part number (e.g., 6510, 8580, Z80A, 6809E, 82S100, 74LS245) or a pin mnemonic (e.g., PHI2, /RESET, /CAS, /DTACK, RW) into the instant search bar to jump straight to matching ICs.
-
3
Toggle Bus Overlays & Signal Direction Flags
Click the bus filter pills above the package diagram to highlight only Power/GND rails, Address lines (A0–A15), Data bus pins (D0–D7), or Active-Low control strobes (/CS, /IRQ, /NMI, /WE) to prevent mis-probing adjacent pins.

4
Probe Live Voltage Rails & Launch Scope Traces
Click any pin on the SVG chip diagram to lock the Pin Inspector readout. Verify expected DC voltage levels with a multimeter or logic probe first, then click the attached Scope Waveform badge to compare your live oscilloscope trace against a known-good reference.
Always locate Pin 1 via the physical package notch or embossed dot before placing a probe tip. Count counter-clockwise down the left column and up the right column on DIP packages—and always clip your ground lead to the IC's own VSS/GND pin to minimize ground-loop ringing.
4116 vs. 4164 DRAM & Dual-Rail SIDs: A 4116 DRAM uses three rails (-5V Pin 1, +12V Pin 8, +5V Pin 9), whereas a 4164 uses a single +5V rail on Pin 8. Plugging a 4164 into an unmodified 4116 socket feeds +12V into its +5V Vcc pin! Likewise, verify 6581 (+12V VDD) vs. 8580 (+9V VDD) before swapping SID chips.
