07-03-08:       I have placed my excess electronics components for sale. See the link on the top of my Home Page.

07-02-08:       I have decided to stop developement on SBC-3.   I am currently requesting those interested in buying an SBC-3 board with 2 65C22's and one modified-65SPI to contact me.   If there is enough interest, then I'll layout and produce enough boards for all who want one.   This request will remain open until Aug 30, 2008.   Please email me with your questions/requests.

06-08-08:       I have added the draft 65SPI SPI Controller Datasheet to the Downloads section.   SBC-3 will use a modified version of this for IO access.

11-04-07:       I have the SBC-3 core up and running.   Look under the SBC Circuit Boards tab for more details.

09-12-07:       I have corrected a schematic error on my AVR PC keyboard IO device.   I had the Clk and Data lines reversed.   Thanks to Eelco Huininga for finding this error!

06-06-07:       Has it already been a whole year since my last update??     Progress has sure been slow but I am still working on my next SBC.   I've been busy with family needs but I have been slowing working on SBC-3.   It will be a completely re-worked board with a 65C816, 512k SRAM, 32k Boot EEPROM, keyboard, video, ethernet, and CF or SD Flash storage.   The details have not been worked out but I expect it to be very capable.   Keep watching this site for updates, and thanks for visiting!

05-01-06:       I've been working on developing hardware interfaces and firmware for Ethernet, Compact Flash, and Video for my next SBC.   I hope to have the prototype ready by December 2006.   In the mean time, I have moved the site once again after finally registering a domain of my own (http://sbc.rictor.org).   Over the past 5 years, this site has had over 20,000 visitors and I've seen many SBC's built.   My thanks to all of you who have helped and supported my efforts!

12-10-05:       I've moved this site to another location. http://home.surewest.net/dnh Current project is a FAT16 compatible interface to IDE/CF devices.   Also working on video and ethernet....

05-30-05:       I've fixed the Simulator's Indirect Zero Page address mode and update the Sim OS ROM with the latest updates; including EhBASIC V2.09. I also updated the SBC-2 OS files. Get them in the Downloads section.

01-17-05:       I've added the source code for the Graphical LCD Text Display's ATMega8 in the Downloads section.

12-10-04:       I've added the source code for the Composite Video Display's ATMega8 in the Downloads section.

08-21-04:       I've added a list of parts that are available for sale.   Contact me via email for details!

06-14-04:       I've added a parts list and supply source list (written by Doug Corarito) to the "Sbc25.zip" support file in the downloads page.

01-29-04:       I've added my 28256 EEPROM programmer to the Device Programmers in the I/O devices area.   Check it out under the "I/O Devices" tab.

01-27-04:       I've added two more devices to the I/O Devices.   One is an Atmel ATmega8 microcontroller programmer and the other is a PIC 16F628 microcontroller programmer.   These are only "hobby grade" but have both been used successfully during my video display experiments.   So check it out under the "I/O Devices" tab.

12-27-03:       I've completed Phase 3 of my Video I/O project.   I have a working text display supporting 40x25 monochrome NTSC video.   I'll be working on a PAL version as well so check it out under the "I/O Devices" tab.

9-12-03:       I've added a tutorial covering the building of assembly files with TASS for use with my SBC and Simulator.   I explain how to build and transfer files to these platforms.   Check it out under the SBC Software section of this site.

8-28-03:       I've updated my 65C02 Simulator again!   It has been rewritten to be compiled using the free LCC compiler.   I've fixed a couple of minor bugs in the debugger as well.   Download it from the Downloads section of this site.

8-20-03:       A New topic was added to the www.6502.org forum called SBC Series Projects.   This will provide a place for all of the SBC users to share project information and ask questions.   Check it out!

8-11-03:       I've updated the sbc-2 v2.5 firmware with the latest version of EhBASIC (V1.10).   The Simulator's OS has also been updated.

7-02-03:       I've updated the IO Devices - Composite Video Test pages with my three-phased test program.   I've included the schematic for my phase two test circuit. [1/27/04 - Phase 2 has been abandoned - see the Text Display for the replacement.]

4-18-03:       I've updated the 65C02 Simulator For Windows program to process the WDC 65C02S processors added opcodes; such as STP, WAI, BBRx, BBSx, RMBx, & SMBx.   I've also updated the operating system of the simulator to properly assemble and disassemble these opcodes.   The program and the source code are available from the Downloads section of this site.

4-10-03:       I've added a NTSC Composite Video Demo to my I/O Devices Page. This is a software-based approach to video generation.

4-07-03:       Another sucessful Bulk order was completed.   I made a few modifications to the board and delivered 23 new SBC-2 v2.5 boards to fellow enthusiasts.   Thanks again for all of your support!

12-11-02:       I have collected requests for another bulk purchase of SBC-2 boards.   This will be a not for profit purchase. With enough participation (15-20 boards), the price will be about $24.   Thanks!

9-30-02:       I had my 5000th visitor to this site.   Thanks to everyone for supporting my projects and providing your feedback.

8-13-02:       I ported a copy of PeterJennings' MicroChess to run on the SBC-2 platform.   The binary and source files may be downloaded under the "Download" tab.   Enjoy!!!

8-1-02:       I've worked with Ross Archer to add a file upload capability to the SBC-2 monitor.   We've added the "U" command which allows the user to send either a binary file (via XMODEM/CRC) or an Intel-Hex formatted text file to the SBC.   The monitor will autodetect the format and download the file!   Look under the "65C02 SBC Software" tab for more info and "Download" tab for the Binary and Source Files!

7-13-02:       I added Lee Davidson's Enhanced BASIC to the SBC Operating System

5-01-02:       I offered to manage a bulk order of SBC-2 boards.   I had over 22 boards ordered!

4-15-02:       I created my SBC-2 board and posted its design specs on the site.

4-25-01:       I joined the "6502 Web Ring" and started getting many more hits to this site.

4-10-01:       I created this web site to display my "65C02 Simulator For Windows" program, the operating system, and the details about my SBC-1 project.
