Looks like you are going to have your hands full for a while then :) It's quite an impressive piece of gear, especially with the VGA out connector. Is it pre-loaded with any firmware that allows you to do anything with it - or is it blank and you have to do it all yourself? It is completely blank. ...

First of all, sorry for not being around here for quite a while. I have to admit I nearly forgot this place, nearly because I am back now! I'll give you a picture then, it's quite a small thing. It's somewhat bigger then a cd/dvd but well, it's smaller then I thought it would be. here is a compariso...

depends...FPGA's are generally expensive but you can get an acedemic version for $99 at digilent. The point was that since I live in europe shipping costs and taxes would raise the price to nearly $189 so I bought it in germany and it costed me with shipping included (no taxes because it was bought ...

Woohow it has been a long long time since I posted here and plans have changed, again. I tried to make it myself a little easier by using an FPGA, but really it's a mess all over again. I currently posses the nexys 2 FPGA board which has some neat features (16 MB SDRAM and 16 MB Flash ROM, PS2 port,...

I will be converting to BCD indeed but, I made a mistake...It is a SIMULATOR not an emulator which makes it way less impressive. Point is I am now trying actually to emulate but that is hard! Already asked for help here: http://tibasicdev.wikidot.com/forum/t-241609/emulator (just a TI-BASIC develope...

Thanks for the swift response. I'll make sure I check out Manchester encoding! Once I have my homebrew computer project done I'll definetely make my own wireless security system!

btw: Cool project! Is it done all ready? Happy with it?

Hmm sounds very interesting...A friend of mine wants to build a wireless video tranceiver for his robot project(!) it is quite complicated I guess. Currently he is trying to device a way to use the internet as the transceiver but that would require building an internet compatible computer on his rob...

Oh well I took them from my TI-84+ so its not an emulation of an emulation but I think I'll do that because then I can show you the syntax of the emulator which is not quite like the syntax in the actual CLU. I have decided to do everything decimal instead of Binary because that is easier for the ca...

Altough I recently did not do much on the project at all yesterday I suddenly had an idea. What if I could write an emulator so that I can show my teacher (and you) how I envision the computer. Well after a day of hard labour it is finally done. But, not in your "usual" format. Since there is only o...

Well there is a reason, they are quite simple to use (so guess how frustrating it is I can't get them to work ) and the book I recently bought is constructed around the use of 4xxx's. Furthermore, there are no reasons besides that I have some 4xxx's chips already and that switching now may financial...

Okay here is the Instruction set as I have it now, notice there are no rotation or shifting functions but these can be made out of the other commands easily (at least rotation can be) Arithemetic Functions: ------------------------- 1.ADD 2.SUB 3.MUL Logical bit Operations: -------------------------...

Well I got the multiplication info from this http://www.asic-world.com/digital/arith ... ultipliers
site. It is a brilliant site! It has tons of information about digital electronics...I have no clue how I got there but I am glad I did.

here is a small update: >I managed to figure out how to multiply in binary! >I got myslef a book called "Digital Electronics" from the Dutch 9which is my native language) company Elektor, it has over 50 breadboard expirements with logic IC's and tells stuff baout how to make NAND's to OR's and vice ...

Yes I think it might eventually look just like that!altough mine has more switches (either because it has more functions or because I can not grasp how a (de)Multiplexer works, probaly the latter ;) ) I'll make sure I'll post all the schemtacis here and since I have to bundle it all neatly for schoo...

Okay then, here it is! As promised I will keep you all up to date on what is happening and what my plans/troubles are. But first I might want to explain what this is all about.. Altough the second part of the forum title is pretty obvious the first part may not be. CLU stands for Calis Logic Unit, C...
