Feedback on MG011 kit

For MG011 Pseudo Random Number Gen designed for RC2014

Put this kit together over the weekend. Very easy to build, instructions were clear and easy to follow. Overall a nice addition to my system. Now I have a hardware-based random number generator. Great transaction and support overall.

MG001 feedback

For MG001 Seven Segment Display - Designed for RC2014

Purchased MG001 for my SC126. Communication w/ the seller was great. Kit arrived quickly and was packaged well. Putting the kit together was easy. I had to contact the seller a couple of times to have my questions answered; response was quick and detailed. The website with the documentation is thorough and helpful. Truly a great transaction. Thanks Jerry!

Exactly what I was looking for

For MG005 Speech Synthesiser - Designed for RC2014

Back in the 1980's, I read a computer magazine article about building your own speech synthesizer for the Commodore C-64 using the SPO256AL2 chip. I rushed off to Radio Shack and used all of my lawnmower money to pick one up. I still have it to this day, and I've bought another one as a backup, but I wasn't sure it was a real or fake chip (fake SPO256 chips are rampant on the online auction shops due to their popularity). I've wanted to relive those fun days when we used to prank call our girlfriends and make it ask if their refrigerator was running.

Last year, I attempted to build Scott Baker's version, but I couldn't work out the exact Bill of Materials and the one I assembled just spoke garbage with a lot of static. I was excited to find this kit on Tindie, and I ordered it as soon as I saw that it had good reviews.
The kit was easy to assemble, and the parts were clearly labeled. I had a few 3.12 MHz crystals in my collection from when I tried to make a similar board in the past, so I used one of those to get an "authentic" sound. I found them on Digi-Key, I think. The biggest advantage is that the SPO256AL2 chip was legitimate and worked as soon as I plugged it in and wrote the quick demo program.

Make sure to read all the documentation so you don't miss the jumper settings to make the demo code work.

Yet another fine module from Mr Geleé's Tech

For MG013 Alphanumeric Display - Designed for RC2014

Yet another fine module from Mr Geleé's Tech: the PCB and parts of superb quality and thanks to the few parts being used, the module is quickly and easily assembled. This module is a perfect for many different uses: as a status display, clock, memory monitor - you decide what you want to do with it. Data output is done using a single command (even from BASIC !!), a working BASIC code example is included in the well written documentation of the module. Money well spent!

Easy to build and works a treat

For MG014 Parallel Port Interface- Designed for RC2014

It's a nicely laid out board with plenty of room to put it together. The only unclear thing is the LED direction markings.

Having assembled it everything works and it is well documented with both example programs and clear documentation on how the port registers are mapped. This differs wildly from the IBM one in terms of bit order and inversion. The inverting differences are no big deal but the bit order one is a bit of a pain for some bidirectional devices that put data on the status lines in what on a PC is a nicely ordered 4bit value. Nothing a lookup table couldn't fix,

With a bit of hacking it's now supported in Fuzix for both printing and ZIP drives. It's driving my old ZIP-100 nicely.
