T2A2 – The transputer is finally here!

Axel Muhr from Germany has released his T2A2 card, a transputer card for the Apple II. Read his announcement and get yours soon!

 

Hey a2central gang,

I’d just like to send you a quick heads-up, that my T2A2 (“Transputer to Apple II”) interface finally became a real PCB – 6 years after you ran a news-line about the prototype (http://a2central.com/2683/t2a2-apple-ii-transputer-interface/). Well sometimes it just takes a tad bit longer :-D

I ran a first initial batch of 20 as I have no idea how big (or small) the interest is, as this is really something, uhm, ‘special’ ;-)

A 65816 in a PAL //e

a2heaven.com has just revealed one of their projects: a microprocessor replacement for the PAL Apple //e. Switch from your current 8-bit 65(c)02 to the 16-bit 65816 one. You are still running at 1 MHz and access 64 KiB of RAM — but is that the first step before a modern accelerator interface card similar to the one a2heaven.com has recently announced for the Apple //c?

Apple-1 clone Mimeo 1 finds a new home

Prolific hardware developer Mike Willegal has handed off management of his original Apple-1 clone, the Mimeo 1. The boards were first made commercially available in 2010 and "have been sold to vintage computer buffs around the world", writes Willegal. "However, the learning part of the process, which is one of things that keeps me interested in my hobbies, has not been there over the past few years."

Henceforth, the Mimeo 1 will be developed and distributed by Corey Cohen, an Apple-1 enthusiast who was previously profiled in the New York Times for his work on restoring an original Apple-1 sold at Christie’s auction house. Find the Mimeo 1’s new home at Cohen’s website.

DynaComp 240V power supply dissection

Long time Australian Apple // enthusiasts and full time technicians Dean Claxton and Mark Cummings, lamenting the lack of official documentation on power supply circuits, have reverse engineered a circuit diagram, schematic and a parts list for the DynaComp 240V power supply (model 699-00136) which was commonly used in the Platinum Apple //e. The DynaComp 110V power supplies are probably very similar and therefore these resources will be useful for troubleshooting those models too.

The article also discusses testing capacitors in-circuit using an ESR meter.

Manila Gear introduces the Apple IIGS VGA Adapter

Mountain View, CA, August 26, 2016 – Manila Gear, makers of the 4soniq quadraphonic sound card for the Apple IIGS, today announced the Apple IIGS VGA Adapter. The adapter lets you connect your Apple IIGS to a VGA monitor that supports 15 kHz. It consists of a DA-15 to DE-15 adapter with an integrated sync separator.

This is a great solution for those of us who have aging AppleColor RGB Monitors, or are still looking for a simpler and better VGA solution.

The adapter has been tested and confirmed to work with a few Benq and Samsung monitors. It can also be used with monitors that do not support 15 kHz, by using the adapter in conjunction with a frequency upscaler such as the Gonbes GBS-8200. A list of supported monitors is maintained here.

The Apple IIGS VGA Adapter retails for $30, and is now available for purchase at https://manilagear.com/product/apple-iigs-vga-adapter.
