Re: Possible to add more features via propeller alone?

Good stuff! Thanks again Jac! I'm going to have to buckle down and learn the propeller. I'd bought the propeller learning lab kit at some point, and it came with a pretty hefty text book for learning the propeller. Here's the kit: https://www.parallax.com/product/32305 For anyone that is interested ...

Possible to add more features via propeller alone?

Hi All, I'm still learning the coding part- and I need to do my homework on the propeller. I figured I'd ask here, as I bet some of you gents will know the answer to this question 'off the cuff': Is it possible to add more features to the Replica 1 using the propeller alone? For example, if you were...

Re: Anybody thought of a light port of Applesoft?

That's really cool, Jac!

I think I'm going to read up on your L-Star project!

Re: Anybody thought of a light port of Applesoft?

Hi All, I've built applesoft-lite from the source code (v.4) Tom posted. I also downloaded all binaries for this version that he hosted on his site (a ROM one that replaces Integer BASIC and Krusader, from $E000-$FEFF, and one to load into RAM at $6000) Using Pom1 emulator, the RAM version at $6000 ...

Re: Replica 1 address decoding question...

Thanks Jac! I'm very slowly learning this stuff, and confirmation I am on the right track helps- looks like I got the encoding part right! :-) Here's the memory map I used... http://www.brielcomputers.com/wordpress/wp-content/uploads/2010/04/memchart.jpg Of course, I googled for this, and have no id...

Replica 1 address decoding question...

I was studying the schematics for the Replica 1 (I checked both the Replica 1 Plus and also the Replica 1 TE), and I can't figure out how the ROM is enabled for the Cassette interface code which I believe is in the ROM at address $C100-$C1FF. I looked up the Binary for the address range for things i...

Re: Two serial ports?

If someone beats me to it, I'm all for it, as I just want an extra serial port for this computer! :-) I've got the components in now, and will be breadboarding shortly, which I think at the very least getting the board to realize when the computer is trying to talk to it as a serial device should be...

Re: cassette interface

I too would like to have a real (not emulated) was to connect a cassette drive. I suspect this would not be best done with the existing serial interface methods, as this is a copy of the same serial connection that is used for the monitor/keyboard(or terminal) connection, and therefore it would clob...

UPDATED: Two serial ports?

Here's where I am so far... I've come up with a theory, that, by using an Atmel AVR, I could design a very simple interface board (simple meaning, easy to design, cheap, low parts count), yet functional serial interface. There is just enough hardware here (I think!) to hard-code the I/O ports to the...

Re: Two serial ports?

I'm really excited about getting a serial card together for these computers. I can't stress enough how much this would add to these cool little computers!!! I'm still reading up and learning about serial ports.. I found this youtube: https://www.youtube.com/watch?v=JJZOTtwpAjA So far, I'm thinking a...

Re: Two serial ports?

Check out the book "Build your own Z80 computer", page 138 (Basic peripherals chapter, section III serial interface) A quick google search shows this book available in google books, and I downloaded a copy in .pdf form that has in the front page the following quote: "Please note: The ...

Re: Two serial ports?

This is what I am trying to find out too! Is it the case that, the serial port that is on the RAMDISK (and also the external serial port that was included I think on some kits) is only for connecting an external terminal if you are not using the onboard terminal (onboard VGA and PS/2 interface)? Or,...

A BBS running on the Altair 8800micro...

For those of you that remember calling BBS's back in the day, I thought I'd share a video I made, demonstrating an RBBS BBS session. https://www.youtube.com/watch?v=Ug6TcmHe1Ko I think it would be AMAZING to create a telnet modem for the Altair 8800micro! RBBS running local is neat, but, there are 1...
