The LOGICAL DESIGN TOOLS EPROM EMULATOR is going to save you both time and money. It will save you time by not having to remove, erase, program and reinstall an EPROM each time you make a small change in the controlling software. It is going to save you money because you will no longer need to buy expensive computers (i.e. TARGET DEVICES) which have SRAM to contain your software, and a PC interface for transferring your software to the computer.
Developing an operational, bug free, easy to use program for a computer (large or small) takes as many as a hundred test cycles. This is especially true for programs in the several hundred line category. More so if your TARGET DEVICE outputs to an LCD screen or monitor because you are constantly changing your software to achieve that 'Easy to use interface'. With the LOGICAL DESIGN TOOLS EPROM EMULATOR each test cycle requires only seconds (11 sec. transfer for 32K file). Compare this to an EPROM test cycle which typically takes 15 minutes. With our LOGICAL DESIGN TOOLS EPROM EMULATOR you are going to enjoy improving your software because there will not be any 'hassels' to cope with, and you will get immediate results.
Using the LOGICAL DESIGN TOOLS EPROM EMULATOR is both fast and easy. Easy because you are not required to remove or unplug anything when transferring your program to the EPROM EMULATOR or when testing your software. Easy because RESET or RESET is totally automated to keep your computer from "going nuts" while data is being transferred to the LOGICAL DESIGN TOOLS EPROM EMULATOR. EASY because when your program is transferring from your PC to the LOGICAL DESIGN TOOLS EPROM EMULATOR, RESET is forced HI or LOW (chosen by options). After transfer is complete, RESET goes HI or LOW to allow CPU operation. FAST because transferring your program from your PC to the LOGICAL DESIGN TOOLS EPROM EMULATOR takes only 11 seconds for a 32K program.
Writing software with the Eprom only method is so time consuming when you spend 15 minutes or more, programming and erasing Eproms, just to test only one revision of your software. Two hours are lost in just 8 revisions. Even the smallest program typically requires 20 revisions, especially when you work with new or unfamiliar parts of a device.
Consider the advantages of owning an LOGICAL DESIGN TOOLS EPROM EMULATOR which is going to work with just about any target processor you buy, so you won't have that "locked in" feeling. Also, the money spent for LOGICAL DESIGN TOOLS EPROM EMULATOR is almost returned with your purchase of an inexpensive target device which does not contain all that extra hardware (i.e. SRAM decoders, SRAM, PC interface, PC plug). Not only will the target devices be less expensive, but, smaller and consume less power.
When you receive your LOGICAL DESIGN TOOLS EPROM EMULATOR it will be enclosed in a black plastic ABS case, not just an open printed circuit board to cause sparks and shorts. Options, such as RESET(HI) or RESET(LO), are set by moving a gold plated shorting block on gold plated posts, not by soldering wires on pads. We also include all cables; IBM XT/AT/386/486 compatible software and Illustrated Instruction Manual. Each LOGICAL DESIGN TOOLS EPROM EMULATOR is tested to ensure it provides 100 NS access time to the target device before shipping. Typical power requirement per LOGICAL DESIGN TOOLS EPROM EMULATOR is about 100 mw (i.e. 0.1 amp).
Supports 8, 16, or 32 bit buss computers. Up to four LOGICAL DESIGN TOOLS EPROM EMULATOR's may be connected together for use in 16 or 32 bit data buss computers. All LOGICAL DESIGN TOOLS EPROM EMULATOR's are identical; this means if you buy only one LOGICAL DESIGN TOOLS EPROM EMULATOR for your 8 bit data buss computer, you won't have to buy two later should you change to a 16 bit data buss.
Software for the LOGICAL DESIGN TOOLS EPROM EMULATOR runs under DOS and includes the following programs.
-- EDITBIN.EXE - HEXADECIMAL/ASCII EDITOR. Used for modification or examination of binary files. Employs split screens to display the values in both HEX and ASCII. Features include GOTO ADDRESS, INITIALIZE buffer to specific value, DISPLAY CHECKSUM of file, SPLITTING 16 or 32 bit programs into separate files, and other features found only with expensive device programmers.
-- MOTR2BIN.EXE - Converts Motorola 'S' files into binary files. Supports 8, 16, 24 and 32 bit forms of MOTOROLA 'S' files.
-- NTEL2BIN.EXE - Used to convert INTEL 'HEX' files into binary files. Supports 16 bit and 'Extended HEX' formats.
-- XMTBIN.EXE - Transfers your 8, 16, 32 bit binary program to the LOGICAL DESIGN TOOLS EPROM EMULATOR. Totally automated device addressing if multiple devices are used (i.e. 16/32 bit buss). Device addressing is built into the hardware and is automatically selected by the software.
-- Plus other programs intended primarily for experimentation or modifying existing software, such as SBST.EXE. SBST sends part or all (in byte widths) of a 8, 16 or 32 bit frame to a specific device.
No card to install in your IBM or compatible computer. Works with any 8088, 80286, 80386, 80486; Notebook, Laptop, Luggable Computer which uses MSDOS and has a parallel printer port (DB 25 PIN connector).
Our software does NOT REQUIRE Device Drivers or TSR's. Device Drivers and TSR's can be a nuisance when your PC begins to malfunction or lock up and software conflicts are suspect.
All programs, except for EDITBIN.EXE, may be used in a batch file. Having all executables in a BAT FILE allows automation of your development process.
Each unit comes with a standard 32K to emulate 2764-27256 Eproms. Units with 64K are also available to emulate 2764-27512 Eproms. Should you buy the standard unit now, you can get it upgraded later to 64K for only $24.00.
Warranty. Each unit has a 30 day parts and labor Warranty and a 10 day money back guarantee.
-- Standard 32K model to emulate 2764-27256 Eproms. Includes cables, XT/AT software and 30+ pg. manual. $129.00 (SPECIAL, but only for a limited time).
-- Upgrade 64K model to emulate 2764-27512 Eproms. Includes cables, XT/AT software and 30+ pg. manual. $149.00 (SPECIAL, but only for a limited time).
-- Engineers Version. Same as above except all IC's are mounted in sockets. No charge. (SPECIAL, but only for a limited time).

Please note: An Eprom Emulator is not a perminent replacement for an Eprom. An Eprom Emulator is used to emulate (temporarily replace) the Eprom while the program you intend to install in the Eprom is under development. Having the ability to transfer your developing program to an Eprom Emulator eliminates the trouble of erasing and programming an Eprom each time you need to test your software.
When you own an EPROM EMULATOR, you are emulating a device which will permanently contain your finished software. The fact that you appear to the target device as an EPROM means the transfer of your software to the EPROM is NOT going to change the behavior of your software. Also, you will not have any hardware differences to compensate for. Just think, when your program performs to your satisfaction, you can take that same exact program and permanently place it in an EPROM. Also, when you buy a target device, it will not have to provide a method for transferring or storing your software. So it's going to be cheaper, smaller, and consume less power.
While using the LOGICAL DESIGN TOOLS EPROM EMULATOR, you will not have to concern yourself with serial communications, baud rates, new communication interface if changing CPUs, or other unique requirements for each target device you buy. When you use a LOGICAL DESIGN TOOLS EPROM EMULATOR, it is going to work the same with any target device that has an EPROM socket, regardless of who made it, and regardless of CPU type (INTEL, MOTOROLA, ZILOG). That's versatility!
