GGLABS and Flirc.tv at the 2018 Bay Area Maker Faire

Bay Area Maker Faire BannerGGLABS and our good friends at FLIRC will be at the Bay Area Maker Faire. This year the faire will be 3 days from May 18th to the 20th. As usual Friday is dedicated to educators and makers while Saturday and Sunday are the general admission days. If you plan to attend the faire feel free to stop by and say hi.

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.

GRAM/512S - 512KB 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/512S is a geoRAM compatible cartridge based on a single 512Kx8 SRAM.

GGLABS and our good friends at FLIRC and plugg.ee labs will be at the Bay Area Maker Faire. This year the faire will be 3 days from May 19th to the 21st. As usual Friday is dedicated to educators and makers while Saturday and Sunday are the general admission days. If you plan to attend the faire feel free to stop by and say hi. We will be showing some of our current projects and a few prototypes still in development.

RAMGS/4 - SIMM based 4MB memory expansion for the Apple IIgs

ramgsThe apple IIgs is the most advanced computer in the Apple II series. Equipped with a 65c816 8/16-bit CPU with 24-bit address space it could address up to 16MB of memory. The original rom 01 model shipped with 256KB of fast RAM, the revised rom 3 shipped with 1MB (both had an additional 128KB of standard RAM and 64KB of sound RAM). RAMGS/4 is a newly designed 4MB SIMM based memory expansion card for this great classic computer.
