SQL Developer Concepts and Usage. This topic covers the main Oracle SQL Developer concepts, and explains how to use the major SQL Developer features. Review Go. Tek System SFR1. M4. 4 U1. 00. K USB 1. Floppy Disk Emulator. Following on my previous review of a 1. USB floppy emulator and testing of the emulator, I realized that the e. Bay market saw the introduction of another floppy emulator. This one is the Go. Tek System SFR1. M4. U1. 00. K 1. 00. 0 bank USB floppy emulator, also attractively priced around US2. The Unit and Inclusions. The device itself has the letters GOTEK in the moulding, and features a three digit seven segment LED display still covered with plastic tape, a USB port, two push buttons and an access LED. The green LED lights up whenever the drive is active. Noregistration upload of files up to 250MB. Not available in some countries. Microsoft Office 2007 applications shown on Windows 10 clockwise from top left Excel, Word, OneNote, PowerPoint these four programs make up the Home and Student.

Google Drive is a free way to keep your files backed up and easy to reach from any phone, tablet, or computer. Start with 15GB of Google storage free. In Lifehackers new video series, Day 1, were tackling exactly what its like to be a newbie in a variety of possiblyintimidating situations, starting off. The right button is used to increment the ones position, the left button increments the tens position, and pressing both buttons momentarily increments the hundreds position. Holding them both may engage the auto format function which will erase all content. In use, this drive allows you to increment the bank during accesses but this may lead to data loss. The increment function appears to cause the change line to be toggled to signal to the controller a disk removal. The other emulator locks out the incrementdecrement during accesses.

Mi Disc View 3.1 Advanced Viewer' title='Mi Disc View 3.1 Advanced Viewer' />The casing itself differs from the other emulator, with a distinctive step shape, and the use of only three screws to secure the unit together. There was also the provision for branding and other button labels which are not provided. The step shape is clearly visible here and may be an advantage when trying to shoehorn the device into non standard floppy drive enclosures, although those often have non standard interfaces as well. Exposed at the rear are jumpers some are labelled for drive select, and others are undocumented. There are also through holes unpopulated which are also for configuration by jumper. The 3. 4 pin interface has the keying pin pin 3 still in place just like the other emulator I had, theres no harm clipping this off for cables with the hole blocked. Its probably a good time to note that this emulator does come with an 8cm CD groan however, the tools provided are arranged arbitrarily, are poor and some improperly licensed. Ill show you some of it later on. It also comes with manuals, although for a variety of versions of products which are not related whatsoever. SMART-CrystalDiskInfo.png' alt='Mi Disc View 3.1 Advanced Viewer' title='Mi Disc View 3.1 Advanced Viewer' />It appears there are separate versions for 7. B, 1. 2. Mb and 1. Mb format, and there is a format which images the disk, and another which interprets folders as a disk and customized versions for sewing machines and networked applications. There are some documentation which refers to a 1. Most of this is there to confuse you, so Id suggest avoiding the CD if you can. The datasheet is provided though with some jumper explanation. Mi Disc View 3.1 Advanced Viewer' title='Mi Disc View 3.1 Advanced Viewer' />The internals consist of a green PCB populated with an STM3. F1. 05 ARM Cortex M3 CPU from STMicroelectronics, a NXP 7. HC0. 4D Hex Inverter Buffer, a 3. Its a little simpler looking compared to the other emulator having no external SRAM or multiple ICs the magic will obviously be in the programming of the ARM CPU. The rear side of the PCB is relatively bare picture is for proof The Unit In Use. I plugged it into the same old Windows 9. I have running since its capable of non standard formats just to give it a go. The unit would display 0. USB stick connected, and would display the same once a stick is connected. Formatting the disks with verification with Win. Image was not a problem at 1. Mb. Surprisingly, a format at 1. Mb also succeeded. B and all non standard 1. Mb, 1. 7. 2Mb, DMF, 8. B, 3. 60k. B, 3. 20k. B, 1. 80k. B, 1. 60k. B all failed. Following the same methodology as before, I performed a pattern fill on the USB key to be used with the device, and I formatted the first 5 banks, and the last bank and found the beginning of the images. It was found that this device also stores sector images, just like the other emulator. The offsets to each bank are as follows Image 0. Image 0. 01 1. 80. Old Super Mario Bros Pc 1985. Image 0. 02 3. 00. Image 0. 03 4. 80. Image 0. 04 6. 00. Image 9. 99 5. DA8. Do you know what this means This is the same scheme as for the other emulator which means, in theory, the first 1. The pattern is obvious and tells us that for 1. Mi. B of any USB key will be used. Therefore, a 2. Gb USB key is enough The Software. A commenter on my previous post said that Ipcas has a similar floppy emulator to the other emulator and had software downloads. Curiously, their software download is similar to the software provided with this Go. Tek system unit but does not appear to work. There are two programs supplied one of them is called UFDISKManager. USB key by extracting the files into a temporary directory, where you can modify them, and then repack them back and write them to the USB key. The language seems permanently fixed to Chinese, and I dont really find it workable You can see that I formatted bank 0. Mb floppy and it detects that correctly. It does not change the binary offset for the other banks however, but this does not work properly, as I will explain later The other pieces of software is UFloppy. Manager. exe with a plethora of options related to pre formatting a USB key for use with the drive, but I havent managed to get it to work meaningfully either. So its pretty much a fail all round with the software. Analyzing the Output. Thanks to the Kryoflux, we can get a little more information about how the drive presents itself to the host. On connecting the Kryoflux, the calibration option returns a value of 8. The Kryoflux itself doesnt test for larger values it may be possible to get 8. This is different to the other emulator which tops out at 8. When reading the virtual floppy, it is very close to 3. RPM with a clean signal on all tracks The first question we should ask is what is being returned on those tracks A quick peek in the hex editor reveals that those tracks indeed return the data in sequence from the USB key so if they were never written by a host, they will return whatever was remnant on the USB key in the gap between images in my case, 0x. BAADF0. 0D. Another question is what happens when we attempt to read a disk which is formatted as a 1. Mb bank Well, as it turns out, the unit emits the full 1. This makes the unit that I have unsuitable for emulating 5. HD drives only good for 1. Mb HD 3. 5. Conclusion. For people wanting to deal with unusual format disks, its a disappointment but at this price, I really dont mind. It works as advertised for 1. Mb HD MFM 1. 8 sectors per track 5. The software is a bit cryptic and generally rubbish, but the compatibility suggests there may be an unwritten agreement somewhere about USB Floppy Emulation, or maybe its a case of someone wanting to remain compatible with the status quo. Whatever it is, its good and bad news. While the first 1. I suppose the good thing is that the reported RPM of this unit is much closer to what is expected, although only having increment buttons and the potential for changing the bank during a write is a bit of a risk. At least, I hope this information comes in handy for anyone who may be thinking of purchasing such a unit Related.
