A wire to the RESET line or physical switch can be added if desired for manual switching.
In most installations no additional wires are needed to use the "wire free" ROM switching feature.
Moudles can be linked to support ROM switching in 32 bit systems which use two ROMs (e.g. In most system setups no aditional wires or switches are required to perform image switching. For example in an Amiga 500 with 512KB Kickstart images you can program up to 4 different version of Kickstart and select between them with CTRL+Amiga+Amiga. The 2MB FLASH chip on board allows multiple ROM images to be uploaded and selected with ease. Built in support for byte swapping so no need to manipulate binary image files on the PC. Program, verify, CRC and dump out the contents from the USB terminal. Options menu allows quick configuration of module through presets or custom setup. Configure and program the module in or out of the target machine via the built in menu system.
Commodore A1200, Acorn A4000)Ĭonnect to the module via USB with your PC or Mac and terminal software (e.g. Link multiple modules for 32 bit (e.g.Can emulate any 8/16 bit mask ROMs and EPROMs with simple adapter PCBs.Switchable pinout for JEDEC (27C400) or Commodore A500 rev3/rev 5 ROM.5v CMOS data output (no pullups required).Wire free ROM bank switch function (kickswitch).Warning do not insert module in an EPROM programmer! Vid and Vpp voltages will damage the module. Pinoutĭirectly pin compatible with M27C400 and AM27C400 UV EPROMs. It can be adapted for use in almost any equipment that has a ROM or EPROM for data or firmware. Highly customisable connections cater for almost any system and use case. The module can be programmed in system (ISP) which makes it ideal for ROM software development.Ģ7C400 family EPROMs support byte mode access and it is simple to use this ROM switcher in an 8-bit computer with a suitable adapter PCB. It is programmed via USB from a PC/Mac eliminating the need for an EPROM programmer (+adapter PCBs) and a UV eraser. The module can be used as a drop in replacement for the ROMs in compatible systems. The Commodore Amiga 500/A600/A1200 and Acorn A3020/A4000 all used this ROM pinout. The 27C400 UV EPROMs have compatible pinout with ROMs used in many computers and electronics from the 1990s. Instead of requiring a UV eraser and EPROM programmer the module is programmed via a USB connection. With a 2MB FLASH chip on board it can switch between four 512KB images or emulate the larger 27C800 & 27C160 EPROMs. This module emulates and is pin compatible with the 27C400 4 Mbit (512Kb x8 or 256Kb x16) EPROM. 16 TTL (3.USB programmable 27C400 EPROM Emulator Introduction.But now with Numato Lab’s USB GPIO adapter, controlling external devices and reading external signals through USB has become very simple. USB-to-GPIO connectivity has never been easy unless you were a USB expert. These Analog inputs can be used to read Analog quantities such as temperature, pressure, etc.
All that you need to operate GPIOs is a standard Serial Terminal Emulator such as HyperTerminal/Teraterm or your favorite programming language such a C/C, Python, Perl, etc… Besides providing standard General Purpose IOs, this product has multiple Analog Inputs as well. Numato Lab’s GPIO devices provide an interface that looks like a Serial Port on your Operating System and thus effectively hiding the complexity of USB. No USB specific knowledge is required to set up and use this module. Numato Lab’s 16 Channel USB GPIO module is low cost easily deployable GPIO USB solution for connecting your PC to other electronic circuitry through USB. 16 Channel USB GPIO Module With Analog Inputs
