Hi every one. First I have to say, I'm sorry, that it took so long to write this part. I wrote the service routines for the next group keys: Prog, Mem, Reg, Move and Rela Inside the groups Prog and Mem, you can use the function-keys: Data, Addr, +, -, INS and DEL Inside the group Reg you can use the...

Hi, everybody. The last weeks I've worked hard to make an assembler for my ISA. (It is made in EXCEL) Well, I've to say, that I'am inspired by mcostalba. One of my wishes was, to have a tool, that would be able to translate mnemonics and produce the ROM-file. Furthermore, I want you to understand ho...

Dear Superryan,

Here is a simple circuit, with which you can study the functioning of the VGA-screen.
If you want to know more, you can send me a PM.

Hi, everybody I'am ashamed, that I've written so little, the last six months. Fortunately, I can say, that not making the program was the issue, but actionally the explanation in particular the translation of it. Most of the time I've spent on the explanation, and often, when I wrote something, I wa...

In this library you will find several useful circuits, among them different counters You can find this library on page 2 of this forum. Maybe it is necessary to replace your counte...

Hi, In this part, I make a start, programming the monitor (BIOS) This monitor will enable you, to write your own programs You can find all the possible instructions in the CU. (10. Units, 05.01 IR+CU) At the property page of the ROM, near the micro-counter, you'll see all instructions. In the Rom, w...

Dear Administrator, Thanks for the compliment. I like to build a computer, that allows an user to run his own programs When you turn power on, the monitor (a program, already present in ROM), controls everything (keyboard, displays, subroutines) With the keyboard, the user can enter HEX-codes (32 bi...

Hi basso95, Like the administrator already said, to help you, we need some more information. for example: which parts do already have, what kind of input do you use, what is your level in electronics, and so on We can help you, if you help us first. I can help you, advise you, but I wo'nt give a tur...

Hi, everyone. At the moment, I wrote part-09, I had to conclude, that the design would not fulfill all desires. Alas, a vacation in the US, during the month September, didn't work along I thought, that I would need a month time, to change the design, in such a way, that it would operate better. Unfo...
