ARMSID
A new replacement of the MOS 6581 and 8580 SID music chip used in the Commodore C64 and C128. Real "plug & play" solution. Just insert instead of the original SID chip into the socket and its done. Accurate sound, significantly lower noise level and less interference from the power supply than the original SID. Automatic recognition of 6581/8580 mode. You can change it anytime by using simple configuration utility to change the SID type, tune the audio filters and test your ARMSID. Lower power consumption than the original. Easy firmware update from the C64/C128 app.

UNICARD mk3b
UNICARD is an interface card for computers SHARP MZ-700*, MZ-800 and MZ-1500**. It allows you to simply run MZF/MZT files from a microSD card and provides emulation of standard SHARP peripherals and a VGA output, as well as other inputs/outputs (USB, RS-232C, Ethernet, PS/2, audio).

The Unicard can emulate standard SHARP peripherals, such as Quick Disk, various RAM disks (RAM, SRAM, SROM, EMM), a floppy controller with 4 floppy disk drives, a serial interface, a KANJI and dictionary card and some newly created peripherals, such as an arithmetic unit ALU, RTC and potentially more, because the firmware is still being updated. The Unicard offers several communication interfaces (Ethernet - HTTP server, USB and RS-232 - USARTShell, 8-bit API MZFRepo).

You are buying just the hardware. There will be firmware installed, but it is community developed and not part of the product and its guarantee. You can download actual firmware and ask for sources if you are able to contribute to development. Some proprietary Keil tools are required. Software configuration is done by Unicard Manager. You have to download it and place on your own microSD card. Unicard is sold without microSD card and without CR2032 battery.

Black version of Unicard is not produced currently. It is here just to sample interst and could be produced later.

* MZ-700 requires SHARP MZ-1U06 expansion or another bus adapter. The firmware support for MZ-700 is currently limited. Only older fw for European version of MZ-700 works. New fw is available for MZ-800 an MZ-1500 and will be adapted for MZ-700 later, but no promises.
** Different Unicard firmware is required for different computers. Choose default firmware and you can change it anytime later by placing particular unicard.app into root of microSD card and switch the computer on.

MZ-700 adapter for Unicard
You can use Unicard Mk3b with Sharp MZ-700 with this adapter. It is possible to connect Unicard directly or with a flat cable.

Adapter supplies +5V power, which is absent on MZ-700 bus edge connector. Power can be supplied by miniUSB connector or short cable from one of the MZ-700 joystick ports.

This adapter is also sold as DIY PCB only.

If you buy this with an Unicard, we will refund the adapter postage, so the postage for adapter will be free. We can do this only after payment, while checking order, sorry for the inconvenience.

ARM2SID +FM
Would you like stereo? Or FM synthesis?
ARM2SID is new TWO SIDs and SFX sound expander (OPL FM synthesis) emulator in one DIP28 socket size! You can add the second socket as the second SID if you have stero adapter or connect wires directly to your Commodore computer.
- up to 12 channels music (two SIDs or FM or one SID and FM)!
- for all C64 and C128 boards
- stereo in any combination of SID models
- automatic fall-back to dual mono if second SID is not used
- configuration and upgrades by software in C64/C128

Easy instalation:
- easy no-soldering solution for stereo SID expanders (MixSID, SIDFX, SID2SID etc.) or dual-SID boards (ULTIMATE-64) with ARM2SID's optional second socket
- or all in one solution useful without any expander, only 6 wires (suplied with particular connector have to be soldered for address, select and audio pins (A5,A8,R/W,IO1,IO2,Audio R)

Attention. No stereo expansion board is a part of the product. Just one DIP28 ARM2SID + 30 cm cable with connector and free ends on the other side to solder it to your Commodore computer or the second SID2 chip socket with 5 or 10 cm long cable with 2 connectors. 5 cm cable should be enough for the most stereo expansion boards.

ARM2SID is out of stock currently. Estimated availability date is the May 2019. You can click on "availability notification" button and we will let you know when ARMSIDs become available. We are sorry for the inconvenience.
