A friend of mine left me some ZX Spectrum clones produced in the 90′s in Czechoslovakia and Russia.

As you can see from the photos i have tried to find the right pinout of the RGB video and audio output.

Thanks again Andrea Pierdomenico.

…from the author website:

Since the end of 2015, it became clear that the “good old” 1541 Ultimate-II was at the end of its life cycle. Xilinx, the manufacturer of the most important chip of the cartridge, had started to increase the prices of the chip. Also the memory chip started to be harder to get and at higher cost. When the news came that the company that made the black plastic cases for the 1541 Ultimate-II had lost the injection mold tool, it became evident that the 1541 Ultimate-II would be no more.

I have given it some thought. What would be the best way to continue with this project? When the feelings of being upset about the lost injection tool had subsided, I realized that this may be the perfect moment for an upgrade. This is when set backs change into opportunity.

Since then, a lot of work, and I really mean A LOT OF WORK has been done to create a successor: the “Ultimate-II+”.  Why not “III”, you may ask or think. Well, the foremost reason is the software. The install base of the “1541 Ultimate-II” is rather large (>3000 units), and I do not want to let my customers down that have just purchased a unit. This means that in case of new hardware, the same software should run on both the new board, as well as on the older board. So, the new board will offer similar functionality. You could see it just as an upgrade, not an entirely new product.

Although the “Ultimate-II+” is similar, there are also differences:

• No more MicroSD!  (… that needs to be pushed in with something sharp, could fall into the case, … etc)
• More USB ports (… one to compensate for the lost SD, and just one bonus: 3 in total)
• IEC connector moved (… further back to facilitate use on some C128 models)
• Integrated Ethernet (… no more need for an external USB2LAN adapter, and a smaller step to CS8900A compatibility)
• Dual Flash (… no more worry that a software bug or upgrade failure leads to a bricked device)
• Integrated Speaker (… who connects a speaker set to the audio jack for hearing drive sounds??)
• External power supply connector with auto-switch over circuit (… for stand alone mode, and to lower the demand on the power supply of the C64)
• Improved Audio (… audio codec, 24 bit/96 kHz*, for sampled sounds and SID emulation)
• Improved Tape connector (… no more custom board and able that snaps in on the bottom, but standard USB 3.0 cable)
• Improved power supply circuits (… for some reason they seemed to break down relatively often)
• Slightly bigger and faster FPGA, as to control the new features

Jean-François DEL NERO (who’s behind the HxC SD Floppy Emulator) recently has released a version of the HxC emulator firmware that is compatible with the STM32 chip used in the Gotek floppy emulators.

This means that the great functionality of the HxC SD emulator is now available on cheaper and more widely available hardware.

The bootloader to convert the Gotek floppy drive in HxC compatible must be purchased on the website HXC 2001 by sending an email to Jean-François DEL NERO. The price of the bootloader is one-off 10 Euro per Gotek that you want to update. Future updates of the software are free and can be made from a USB stick

The HXC Usb (Gotek) firmware supports:

Release notes Firmware USB HxCFloppyEmulator v3.0.8.2a

• HD floppy disk format issue corrected : write buffer size corrected.

The Tulip system I was a 16-bit personal computer based on the Intel 8086 and made by Tulip Computers, formerly an import company for the Exidy Sorcerer, called CompuData Systems.

Its 6845-based video display controller could display 80×24 text in 8 different fonts for supporting different languages, including a (Videotex based) font for 2×3 pseudo graphic symbols for displaying 160×72 pixel graphics in text mode. The video display generator could also display graphics with a 384×288 or 768×288 (color) or 768×576 (monochrome) pixel resolution using its built-in NEC 7220 video display Coprocessor, which had hardware supported drawing functions, with a very advanced set of bit-block transfers, it could do line generating, arc, circle, ellipse, ellipse arc, filled arc, filled circle, filled ellipse, filled elliptical arc and many other varied commands.

Its memory could be upgraded in units of 128 KB up to 896 KB (much more than the 640 KB of the original PC).

It included a SASI hard disk interface (a predecessor of the SCSI-standard) and was optionally delivered with a 5 MB or 10 MB hard disk. The floppy disk size was 400 KB (10 sectors, instead of 8 or 9 with the IBM PC) or 800kb (80 tracks).

It ran at 8 MHz, almost twice the speed of the IBM PC XT which was launched only a few months earlier in July 1983. It had the possibility to use an 8087 coprocessor for math, which increased the speed to > 200 kflops, which was near mainframe data at that time.

After initially using CP/M-86 it quickly switched to using generic MS-DOS 2.00. There was a rudimentary IBM-BIOS-emulator, which allowed the user to use WordStar and a few other IBM-PC software, but Compudata B.V. shipped WordStar and some other software as adopted software for this computer. There was a programming support by Compudata B.V. with MS-Basic, MS-Pascal and MS-Fortran. On a private base, TeX and Turbo Pascal were ported to the Tulip System 1.

DirMaster is a Windows-based GUI application designed to help Commodore enthusiasts explore and manage their disk image collections.

DirMaster supports common (and uncommon) emulator disk image formats (such as .d64, .d81, .d2m, etc), almost every native Commodore archival format (such as .arc, .sda, .lnx, etc), and many native graphic formats (such as koala, doodle, amica, etc).

DirMaster was designed to give users a perfect blend of familiar appearance (e.g. natural looking disk image contents using the PETSCII character set) and modern GUI functionality (e.g. drag and drop, opening multiple disk images at once). The first version of DirMaster was released in 2006.

v3.1.1 addresses a few bugs reported by users:

• Issue opening NAT partitions (.dhd)
• .dhd performance (no md5, .dhd BAM)
• Horizontal BAM display (.d71)
• Disk initialization when unzipping a 1-4! zipcode set when dragged from Explorer.
