GTERM25-A01 - DB25 Active SCSI Terminator with diagnostics LEDs

Submitted by GG on Thu, 11/10/2016 - 22:59

A new version of this project is available here

GTERMActive termination is required to get newer higher performance drives working on vintage computers. Unfortunately both the Amiga and older Apple computers use a DB25 SCSI connector which makes finding a suitable terminator quite difficult. GTERM25 solves this problem providing a high performance active terminator with a DB25 connector and SCSI diagnostic LEDs.

E2R16 - 27C400 programming adapter for Minipro TL866

Submitted by GG on Sun, 03/27/2016 - 00:52

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.

T232-A02 - Simple DB9 RS232 monitor and breakout board

Submitted by GG on Fri, 01/22/2016 - 15:25

A new version of this project is available here

T232RS232 monitors are quite common but most of them use the standard good old DB25 connectors. The majority of the RS232 ports in use today however use the smaller DB9 connector. This forces the use chains of adapters to get the commercial monitor/breakout boards working. The GGLABS T232 solves the problem by providing native DB9 connections.

A520HD - Commodore Amiga RGB to HDTV Component Adapter

Submitted by GG on Fri, 01/15/2016 - 13:33

A520HDThe GGLABS A520HD is the HDTV equivalent of the classic Commodore A520 TV modulator. Instead of encoding the Amiga video signal to a low quality composite output it converts the RGB output to a high quality YPbPr signal compatible with HDTVs with a component input. The A520HD connects to the Amiga 23-pin video port and is powered directly from the system.
