VCF East 9.1 Workshop

by on Feb.13, 2014, under News

We are pleased to announce that we will be hosting a workshop Saturday April 5th at the Vintage Computer Festival East 9.1 VCF East.  

ONLINE SIGNUPS ARE NOW CLOSED. IF YOU STILL WISH TO ATTEND THE WORKSHOP, WE WILL HAVE A FEW EXTRA KITS THERE FOR YOU TO CHOOSE FROM!

vcf

This year will be the first workshop in 2 years. Now is your chance to build a kit in a classroom environment with the designer! Not only do you get the workshop for free, the kits are offered at a 10% savings! Pre-registration is required but if you have a firm commitment to do the workshop and want to pay at on the day of the workshop, you can email me at vince@brielcomputers.com and I will get your information and have a kit for you. We require pre-registration because we have to ship the kits in advance to the venue and need to know how many to send. There is limited seating available so don’t wait. These prices are only for the workshop, kits will be issued at the workshop.

Kits for the workshop are:

replica 1

The replica 1 is a functional clone of the apple 1 and uses some of the original chips like the 6502 and 6821. With the help a micro-controller the kit has only 10 chips and is a great kit for the beginner to intermediate builder. Normal kit price is $149 but the VCF East workshop special is only $134. This is for the standard edition similar to the tenth anniversary edition.

PockeTerm

The PockeTerm is a single board terminal that uses a Parallax Propeller micro-controller to emulate a VT100 terminal. With a special pass-thru serial port you can connect a PC to the PockeTerm and download data right to the host device. Just add your own PS/2 keyboard and VGA monitor and you have a powerful terminal in a small compact size. Perfect kit for the beginner. List price is $69 but the workshop special price is only $62.

Altair 8800micro (SOLD OUT)

The Altair 8800micro is a miniature sized version of the MITS Altair 8800. It comes with a 32K SRAM, built in terminal with your choice of VGA or composite connection (or both), SD card slot for program storage. The processor is a ATMega8515 with front panel and CPU emulation to reduce chip count. For time constraints, the front panel will be pre-assembled. A good kit for intermediate builders. List price on the Altair 8800micro is $219, workshop special price is only $197!

Just added! The Micro-KIM

The Micro-KIM is a reduced sized replica of the KIM-1. The KIM-1 was a single board computer designed to help aide with 6502 engineering development. The Micro-KIM has a reduced chip count with no micro-controllers and much of the original design. A few changes were made for more RAM and 6532 and EPROM replace the 6530. This kit has many components and is recommended for intermediate builders. List price on the Micro-KIM is $109 but the workshop special price is only $98!

replica 1 tenth anniversary edition

by on Nov.28, 2013, under replica 1

R110As previously mentioned in A2central.com the new replica 1 tenth anniversary edition is here. It’s hard to believe it has been 10 years since the replica 1 was created. In celebration of 10 years of kits, we have a limited edition replica 1 ten board. The new design is our sleekest and most modern design ever. The mini USB interface is not only a power source, but has a built in USB to serial interface allowing you to have a virtual COMM port on your PC. You can run your entire replica 1 from a USB port on your PC or from a USB power supply.R110 kit

The new replica 1 ten limited edition has a unique red color distinguishing it from prior versions. As such, we are limiting it to only 50 hand serial numbered units. Why 50? Well, that is the number of apple 1 computers believed to still be in existence. In order to maintain an economical kit with today’s rising component prices, we found ways to reduce components and made some hard choices too. Gone is the ATX power supply option along with the 40 pin replica 1 header, however, there will be ways to get these features as needed. Don’t have a USB power supply, we now offer a universal USB power supply R110 DIAGRAM

The new design allowed us to eliminate the 1MHz oscillator and now the Parallax Propeller controller generates the system clock. We added a larger EPROM so you can now select between the original BASIC or the new Applesoft lite. We were also able to reduce chip count using the Propeller to handle critical I/O glue logic processing.  All these changes makes it possible to not only maintain the price, but also makes a smaller, more efficient board.

Preordering is over, orders are being filled.

replica 1ten limited edition kit $149

replica 1ten limited edition assembled and tested $199

replica 1ten universal power supply and cable $19

Maker Faire 2013

by on Apr.01, 2013, under News

It’s official, we are going to the Maker Faire May 18th and May 19th. The Maker Faire is a gathering of people who make things, naturally this is a perfect fit for us. Last year we only brought the Altair 8800micro for people to play with and our table was always crowded. This year we are going to bring all the platforms and some that under development.

We are probably going to need help. If anybody is planning on attending and would like to help, we can compensate with a free entry pass. You must spend at least 4 hours at the table in order to qualify. If interested, please email me and I will be making a decision on that this month. You must be familiar with our products enough to talk about them to people who come up.

Hard at work designing the next platform

by on Mar.31, 2013, under Vince's blog

I’ve been spending my free time working on a new project. This platform system will have a 65C02 and emulate the OSI 600 Superboard II or Challenger C1P. Visit the forums for pictures I’ve posted of my messy wire-wrap board with tactile buttons for a keyboard. The final version will have larger buttons but I’m having a difficult time getting buttons that are the right size, right price and has different sizes for SHIFT, RETURN, ENTER, and SPACE BAR. I’ll come up with something but I’m open to any ideas. Just email me at vbriel@yahoo.com and I’ll look at your suggestions.

What’s great is the wire-wrap board is actually really stable, almost as good as a PCB and yet I don’t have any caps on the chips for noise. Right now, I’m ready to implement the serial interface. I’m not going to do the cassette interface as they are just a real pain to deal with. After I have that working and an external keyboard option, I’ll lay down a board and see how things look. If you are interested in me going into production on this, email me and let me know so I can get an idea of how many people might want one.

Waiting for approval from Maker Faire

by on Mar.13, 2013, under Vince's blog

Maker Faire in the San Francisco bay area is a huge venue with so much to see and do. Last year was won of the best times I’ve had at a venue ever! I hope that my application to show my equipment is approved so I can return again this year. In the mean time, I will plan on being there.

Well, my wirewrap project has been on standby while the design details get worked out. It appears that I’m running out of I/O pins on a micro controller and I’m having to dance around that a bit. I should be starting today. This may be my first board that is all 3.3V based. My other boards all use standard TTL 5V logic levels for most of the work and 3.3V where needed. This causes interfacing issues so I may think outside the box again. I like having all my projects do something a little different. The replica 1 TE was the first kit I used the Propeller on. The Micro-KIM was the first kit I kept most of the original design. The Altair 8800micro was the first CPU emulation I wrote. What’s next? Hopefully I can post pictures soon, but I don’t want to show something that is years away, so I’ll post updates when I have a board working.

What I can say is that with the help of Jac Goudsmit I have a Propeller micro controller connected to a 6502 bus using the Propellers onboard memory as video RAM. This means I can connect a Propeller controller to a 6502 system and directly address video RAM at 1MHz speed. We also have the ability to eliminate ROM this way but the project I’m working on also has a serial port and keyboard. This is where aspirin gets applied. We need to shuffle 1 or 2 pins to give us the I/O required for everything. Once this is done, the project will make a nice single controller I/O package for 8 bit processor systems.

Wire wrap

by on Feb.27, 2013, under Vince's blog

I’m going to wire wrap a project that I’m working on starting today. It takes a few days for me to do a board this way because I like to do it in small sections at a time so I don’t make mistakes. If this project works, it’s one I’ve wanted to do for a while but never had the time (still don’t). Without too much information I can say that I’m working with another 6502, this time the WDC65C02 at 3.3V and the whole circuit will be 3.3V, a change from my other designs. In the past I’ve kept my circuits at 5 volts just like vintage machines, but this project is a little different because of the video interface. As soon as I have a working wire wrap version I’ll post pictures and details.

VCF SouthEast Workshop Announced

by on Feb.13, 2013, under News

We are going to be hosting a workshop at the VCFSE in Roswell, GA just north of Atlanta on April 20th and 21st. There are 4 different kits to choose from from beginner to more experienced builders. If you have never experienced the fun of a workshop now is the time. Building a kit in a classroom type setting is great fun and really has that 70′s computer feel to it. This will be a next generation workshop as I can’t physically be onsite but will be using a video conference setup to assist in the workshop. There will be experienced people there with plenty of soldering experience to help those who need guidance with soldering. I will be available on video chat to help answer more kit related questions or just to chat and answer general questions. So, you can not only build a kit, but pick my brain.

The workshop is free, simply order the kit you want to build from the VCFSE Workshop page.

Registration ends April 12th and is limited to 12 entries, so don’t miss out!

JUST ADDED: Tools needed for the workshop

Soldering iron 25-40 watt, 30-35 best
solder
wire cutters to cut the extra length off of resistors/capacitors, etc.

Sign ups are now open and on a first come first serve basis with limited seating. You can order your workshop here:

VCFSE WORKSHOP

Please contact me if you have any questions.
