CompuPro - History

CompuPro started out as a company call Godbout Electronics founded by one of the legends of the early micro-computer era, Bill Godbout.  Unlike some of the other S-100 computer founders Bill had quite a bit of experience in building and selling computer/electronic equipment. He started in the business working as a manager and buyer for a guy named Mike Quinn who had a legendry electronics equipment store near Oakland Airport in California. Mike's store in the early 70's was a hive of activity where pioneers in the field like Lee Felsenstein, Bob Marsh  & Gordon French (Processor Tech) , George Morrow (ThinkerToys, Morrow Designs) , Chuck Grant & Mark Greenberg (Northstar Computers) , Howard Fulmer  (Equinox-100), Brent Wright (Fulcrum)  and many others hung out.  Eventually Bill started his own mail order business in the early 1970's selling electronic experimenter kits.  He setup in the building behind Mike Quinn -- thereby always being in contact with new products, ideas and people. 
 
Bill started in the S-100 board business in 1976 by selling RAM memory boards out of his Godbout Electronics mail order business. His contacts and experience in getting chips fast and at good prices help him get going quickly and allowed Godbout Electronics to fill a market need for boards that Altair, IMASI and even Processor Technologies could not meet in those early days.  In the end Godbout/CopmuPro had more different types of S-100 RAM boards than anybody else in the business. All their boards were static RAM boards. As the business grew the evolved into most other S-100 board types eventually putting together complete S-100 systems. Their S-100 boxes were arguably the most solid and reliable ever made. His innovative products played a large part in the success of the S-100. Bill played a major role in setting the specs for the S-100 bus IEEE-696 standard, being one of its authors.

CompuPro made a number of complete systems over the years.  The CompuPro 8/16 came in various forms of capability and probably represented the best example of a S-100 boards cooperating with each other. It was one of the last commercial systems to come out for the S-100 bus. There are still some of these boxes around still working! At a late point in the companies history CompuPro started to call themselves Viasyn.  Late boards were labeled with this name.

The CompuPro 8/16 was probably the last commercial system to come out for the S-100 that was marketed to both hobbyists and commercial users in the mid to  late 1980s.  However like Cromemco, Compupro designed and sold even more advanced systems based on the S-100 bus to commercial users up until they went out of business in 1990/91. These systems were of little interest to hobbyists because of their extreme cost, and the fact they were primarily designed to support connections to multiple users each working at a “dumb terminal”.

A note of caution: some of the later Viasyn boards and systems were run without the voltage regulators on the boards. Instead, 5V was supplied on a non-standard S-100 bus.  If you put these boards into a standard S-100 system without the regulators reattached, you will fry the board IC's.

Huawei Router B311221 Unlock Firmware

Unlocking firmware typically refers to removing network carrier restrictions (SIM-locking) or gaining administrative control to change settings restricted by your ISP. Because this process involves technical risks and potential legal implications depending on your region and contract, 1. Understanding "Unlocking" Carrier Unlocking: This allows you to use a SIM card from any provider. For many Huawei B311-221 models, you can request an unlock code directly from your original carrier once your contract is fulfilled. Firmware Modding: Some users seek "debranded" or "unlocked" firmware to access hidden features (like VOIP settings or specific frequency bands). This is often done via tools like Balong USB Downloader or specialized forums like 4PDA or GSM-Forum. 2. General Firmware Update Process If you are simply looking to update to the latest official firmware to ensure stability, you can follow the official manufacturer steps: Via Web Interface: Log in to 192.168.8.1 , navigate to Advanced > System > Update , and check for online updates. Via AI Life App: Connect to your Wi-Fi, open the Huawei AI Life App , and select Updates to see if a new version is available. 3. Risks of Custom Firmware Bricking: Using the wrong firmware version (e.g., trying to flash a with B310 firmware) can permanently disable the device. Voiding Warranty: Modifying official software will void any remaining manufacturer or carrier warranty. Security: Unofficial firmware from unverified sources may contain vulnerabilities or backdoors. 4. Common Troubleshooting: Factory Reset If your router is acting up or you have forgotten your admin password, a factory reset is the first step before attempting firmware changes: Log in to the web interface. Go to System Settings > Backup and Restoration . Select Factory Reset and confirm. Alternatively, use a pin to press the physical Reset button on the back of the device for 10 seconds.

Guide to Unlocking the Huawei B311-221 Router Unlocking your Huawei B311-221 router allows you to bypass carrier restrictions and use SIM cards from any provider. While many users seek "unlock firmware" files, modern unlocking often relies on official IMEI-based codes that are safer and more permanent. Methods to Unlock Your Router There are two primary ways to achieve a network unlock for this specific model: 1. The SIM-Unlock Code Method (Recommended) This is the safest method as it does not involve flashing modified software that could "brick" (permanently disable) your device. Locate IMEI : Find the 15-digit IMEI number on the sticker at the bottom of your router or in the admin panel under Advanced > System > Device Information . Obtain Code : Use a trusted unlocking service like MobileUnlocks or DirectUnlocks . These services typically charge a small fee ($3–$8) to provide an official code based on your IMEI. Enter Code : Insert a SIM card from a different carrier into the router. Connect to the router via Ethernet and go to http://192.168.8.1 in your browser. Log in (default is often admin/admin ) and a prompt for a "SIMLOCK Code" should appear. Enter the code you received to unlock the device permanently. 2. Firmware Flashing (Advanced) Flashing modified firmware is typically only necessary if the router's web interface is restricted or if you want to change deep system settings like the IMEI (for mobile-only SIM plans). Risks : Attempting to flash original or modified bootloaders without a proper backup can erase the flash memory, making the device unbootable. Modified Firmware : Some community forums and Google Drive links host files claiming to be unlock firmware, but these carry significant security risks and should be used with extreme caution.

Unlocking the Huawei B311-221 router typically involves using an IMEI-based network unlock code rather than flashing modified firmware, which can risk bricking the device. While "unlock firmware" files are often searched for, modern Huawei routers are generally unlocked by entering a unique code into the web interface when a SIM card from a different carrier is inserted. 1. Official and IMEI-Based Unlocking The safest way to unlock the B311-221 is through authorized methods that don't modify the core software, ensuring the device remains stable after future updates. Carrier Request : Contact the original ISP that provided the router. Many ISPs provide the unlock code for free or a small fee once the contract is completed. Third-Party Services : Sites like ExpressUnlocks MobileUnlocks offer remote unlocking for a fee. Requirements : You will need your 15-digit IMEI number , which can be found on the device sticker or by navigating to Advanced > System > Device Information in the router's web portal. : Once you have the code, insert a non-authorized SIM card, access 192.168.8.1 , and enter the SIMLOCK Code when prompted. 2. Firmware and Software Modification Exercise caution with firmware files found on unofficial forums, as these are often specific to certain hardware revisions or regions.
