   Thought I’d shoot an update your way about what’s been going on in the CoCo world.

   Vcc Emulator update – It’s now at version 1.42 and supports Windows 2000, XP, Vista and 7. New home page for it: http://vcc.20x.cc/

   In the last few years we’ve had a MicroSD Drive Pak, 6551ACIA Pak and Wireless Pak created by Roger Taylor over at coco3.com. They use a heavily modified version a DECB called CoCoNet to add all sorts of drive configurations once only dreamed about.

   A fellow named Aaron Wolfe took Cloud9′s DriveWire3 pack and created a 4th version in Java that is cross platform for Win32, Mac, Linux and virtually any platform capable of running Java. It’s opened the CoCo to Internet BBS’s via telent thru the PC host machine and even acts a webserver. More info is available here: http://sites.google.com/site/drivewire4/ (Aaron, Boisy Pitre and a couple other guys teamed up to win the 2010 Retrochallenge Winter Warmup)

   Several people have worked on an FPGA CoCo3 on an Altera DE1 board that is as close to the much talked about CoCo4 as one can get. It can even run at 25MHz. There’s not a dedicated webpage for it yet, but, it’s in the works.

   A couple websites you might want to add:

   http://www.coco3.com – The CoCo Super Site

   coco.randomrodder.com (my CoCo-centric page)

   coco.randomrodder.com/forum – dedicated to CoCo talk about all subjects, but, also have a section for other popular Tandy/Radio Shack computers.

   Keep up the great work on the TRS-80 site!!

   Brian
