In my project of a modern replica of a retro computer “Agat-7” I needed to generate several different clocks. Some of them can be produced by the PLL built in FPGA, others are a simple division of the main clock. But there is another group of clock signals that are not as simple to get.[…]

Category : CP/M
In this post we will check some programs for CP/M and learn how to load your own programs on “RAM-disk”. External command POWER is intended to work with files in a RAM and the “RAM-disk”. It allows to view files, edit them, rename or erase them, as well as to view and edit data in[…]
Finally we reached the most exciting part – we will launch CP/M operation system on “UT-88”. This system was initially developed in 1975 by Gary Kildall of Digital Research, Inc. for Intel 8080 based computers. “UT-88” is based on the Soviet analog of this processor (KR580VM80A), so it was possible to adapt it for this[…]

- Moving AGAT-7 retro-compute… by Electronics Fun
As you may remember, I’ve designed a universal platform for building retro-computers “Retrobyte”. I have successfully tested it by building the “Mikro-80” computer a few months ago and now I’m working on adapting my other retro-computer project “AGAT-7” to this platform. “AGAT-7” requires more functionality than “Retrobyte” has, so I’ve build an extension board for[…]

A blog format is not very suitable for short status updates of my projects, sharing ideas or interesting facts and news. So, I have created a twitter account to supplement the blog. You can now see the latest tweets on the right side of the home page. The detailed articles are still going to be[…]
- Computer “Mikro-80… by Electronics Fun
The computer “Mikro-80” was made in the Soviet Union in 1980 by a team of enthusiasts before in 1982, the magazine “Radio” began publishing its documentations and schematics. In a nutshell, this was the first accessible personal computer in the USSR; in that era, only single digits of people in the country had the ability[…]
- Retrobyte Rev.B by Electronics Fun
In my previous post, I explained my idea of a modular platform for building modern replicas of retro-computers, of which the Rev.A has already been built and tested. In the process, I found a few things to improve: On the silkscreen, the diode D1 was shown incorrectly (the cathode points to the anode) The voltage[…]
- Retrobyte – a univers… by Electronics Fun
During the time I worked on the “Agat-7” replica, I came across the need for constant changes and improvements; these resulted from either new ideas or troubleshooting. Some of these troubleshoots involve tinkering with the circuit board. Currently, I have four different revisions and modifications of PCB’s for “Agat”; this isn’t even the total amount,[…]
- How to add bluetooth music … by Electronics Fun
The multimedia center in my car is quite useful – it features a built in GPS navigator, a rear-view camera, an MP3 player and several other handy functions. However, its greatest weakness is the inability to play music via Bluetooth. The only supported option is the hands-free bluetooth phone connection mode. To listen to music[…]
- “Maximite” computer by Electronics Fun
Not so long ago I found out about a very interesting computer under the name of Maximite. It is built on the microprocessor PIC, on which are assigned all the main functions of this computer. This small device was made in 2011 and became popular enough so that now some games and programs were made for[…]

In the previous post, I promised to tell you about the holders that I made for the spool of plastic for my 3D printer. In the original kit, there is no holder or support for the plastic and it just sits there next to the printer. The spool, positioned thus, often tangles and requires constant attention. This[…]

It was always a problem to find a proper enclosure for my devices. So, I decided to build a 3D printer for these purposes. It is a great project to build. It can be used not only for customised enclosures but for all sorts of other projects. I didn’t want to buy a pre-build printer[…]

I’m about to finalise my Rev.0 of the modern replica of the retro-computer “AGAT-7”. The next step will be Rev.A design with fixed mistakes, improvements and some new ideas. In this post I’m going to summarise the Rev.0 experience and share with you with some ideas for Rev.A. At the moment the Rev.0 computer starts[…]
