A2SCSI-A01 - Apple II SCSI card clone
Submitted by GG on Sat, 10/19/2019 - 17:50A new version of this project is available here
The Apple II SCSI card from 1986 was one of the first interface cards to attach a Hard Disk Drive to the Apple II line of computers. A2SCSI is a clone of the last revision (rev.C) of the card with a few enhancements to improve compatibility with modern SCSI drives.

GGLABS Memory Test V0.44
Submitted by GG on Sun, 09/15/2019 - 00:39
GMT (GGLABS Memory Test) is a new developed memory test for vintage computers optimized for speed and coverage. The code is based on the test algorithms described in "Testing Semiconductor Memories: Theory and Practice" by A.J. van de Goor. The program is mostly in C plus small sections in assembly. It is free software and released under the GPL v3 license.

GZ/80-A02 - Zilog Z80 turbo card for Apple II computers
Submitted by GG on Sun, 06/16/2019 - 22:47A new version of this project is available here
The Microsoft Softcard was the first card to allow CP/M software to run on the Apple II. It was originally developed to simplify the porting of Microsoft Basic to the Apple II. It turned out to be a great success and at some point in time it was the most popular CP/M platform in use.

UNICART - Universal Commodore 64/128 Cartridge
Submitted by GG on Tue, 06/04/2019 - 20:01
After we developed the UNICART/D many customers asked for a more compact version of the cartridge without the pass-through connector. The board uses one standard PLCC32 flash ROM up to 4Mbit. In C64 mode 8K, 16K and 16K Ultimax cartridge modes are supported. In C128 mode both 16K and 32K cartridges are supported.

F2R16 - Flash based ROM Replacement for Amiga Computers
Submitted by GG on Thu, 04/25/2019 - 22:02
The Amiga, like many other computers of the late 80s, uses 16-bit wide mask ROMs to store the machine firmware. Unfortunately, the pinout of these ROMs is incompatible with the JEDEC defined EPROM pinout. Memory manufacturers produced "ROM compatible" EPROMS like the 27C400 to allow development and quick turn manufacturing. These EPROMS are however becoming quite hard to find and still require a UV lamp to erase the chips. F2R16 brings all the benefits of modern flash memory technology to any platform designed to use these obsolete devices.
