GLINK-LT - User Port RS232 for Commodore 8-bit Computers

glinkltGLINK-LT is a modern clone of the Commodore VIC-1011A RS232 User Port adapter for Commodore 8-bit computers. The adapter is fully supported by the standard Commodore BASIC at up to 2400 baud. Jumpers allow the card to be configured as a UP9600 for 9600 baud operation in Novaterm and Striketerm. A reset button and a 5V header are also provided for added convenience.

GRAM/1D - 1MB geoRAM clone for Commodore 64/128

geoRAMThe geoRAM is a 512KB memory expansion for the Commodore 64 and 128 designed by Berkeley Softworks for use with GEOS. While not as fast as the Commodore REU due to its lack of DMA capabilities, it still provides a significant performance boost. GRAM/1D is a 1MB geoRAM compatible cartridge based on a two 1Mx4 DRAM devices.

Retrochallenge 2017/10

geoRAMThis year our staff decided to enter the retrochallenge competition. Our goal is to reverse engineer the Berkely softworks geoRAM and publish what we discover under the GPL. The geoRAM is a 512KB memory expansion for the Commodore 64 and 128. Unlike the Commodore 1750 REU, which contain a custom chip, the geoRAM is built completely out of standard TTL chips.

GLINKUSB-LT - User Port RS232 to USB for Commodore 8-bit Computers

glinkusbGLINKUSB-LT is a modern variation of the Commodore VIC-1011. Instead of providing a legacy 12V RS232 connection, it provides a USB Virtual Com Port (VCP) suitable for direct connection to any modern PC. The adapter is fully supported by the standard Commodore BASIC at up to 2400 baud. Jumpers allow the card to be configured as a UP9600 for 9600 baud operation in Novaterm and Striketerm. A reset button is also provided for added convenience.

MACSIMM - Programmable ROM SIMM for Mac SE/30, IIfx and IIsi

MACSIMMThe Mac SE/30 was the fastest of the classic compact black and white Macintosh computers. It featured a 16MHz 68030 with 68882 FPU and a 32-bit memory interface and supported, albeit not officially, up to 128MB of RAM. Unfortunately the SE/30 ROM contained some old code that used 24-bit addressing making it 32-bit dirty. Many classic computer enthusiasts make their SE/30 32-bit clean by installing a Mac IIsi ROM SIMM. These are nowadays quite rare and difficult to find.

E2R16 - 27C400 programming adapter for Minipro TL866

MiniproThe Minipro TL866 is very popular among hobbyist because of its low price and ease of use. Its list of supported chips is however somewhat limited compared to more expensive professional programmers. The E2R16 adapter adds support for the ROM pinout compatible EPROM of the 27C400 series which are compatible with Amiga computers and many arcade machines.
