And now the third, a fully functional and complete with the documentation.
A German developed system by Micronic Computer Systeme, short MCS.

I also found over the years documents and dumps of ROMS for the big brother, the MCS Beta 8 development system.

This is a good moment to celebrate the new family member of KIM-1 like systems with better scans of the paperwork for MCS Alpha 1 and the cards and software of the Beta 8, more new photos and a study into the ROM dumps with disassembly and published listings.
You find the result here.

The ALPHA-1, made by Berliner Unternehmens MCS (“Micronic Computer Systeme GmbH”) is an early computer, produced in 1977. The design is influenced heavily by the KIM-1 with many improvements and enhancements. The firm is in business, though the original founders have left a long time ago and besides a page on the website about the history nothing substantional is available.

The Alpha 1 is ready to run and has a KIM-1 like look and feel, like the KIM-1 compatible cassette file format (hypertape) and a cased display/keyboard I/O system.
With connectors for audio tape and TTY.

The system is made up of:

• M622 CPU karte (inserted on top of computer) with 6502 1 MHz, 1K SRAM (8×2112), buffers, address decoding, reset
• M626 Tastatur – Anzeige (8x seven segment LEDs, keyboard with 24 keys, 4 LEDs L1 ..L2), 2 relays for cassette recorder motor control
• M627 Hauptplatine I/O print (2x 6532, Audio tape interface, TTY interface, system ROM with MONA 1 monitor
• Power supply build in case

MONA A 1.10.77 ROM

The source of MONA A 1.10.79 is listed in the Handbuch (manual). I have recreated the source in MOS Technology assembler syntax standard. It delivers a 2K ROM image.

I also dumped the ROM of my MCS Alpha 1 (in a TMS2716 2K EPROM) and checked for changes. The routine at label STP (initialization code) is slightly different.
So also the source of this dumped version is recreated. You find all sources (from listing and dumped ROM) and binaries and changes in the archive downloadable below.

Gebroeders Bruyn, Vinkeveen. Small company, custom made electronics and standard microprocessor boards and systems aimed at industry and hobbyist.
During my years with Radio Bulletin we often worked with Brutech, and I visisted their office/manufacturing plant in Vinkeveen several times. The BEM-bus became the standard bus for expansion at Radio Bulletin after the first BEM-1 card was connected to the KIM-1 by Dick de Boer. Brutech specialized in the beginning on the KIM-1/VIM/SYM-1 expansion cards, later on they made their own CPU cards and besides the 6502 cards with CPUs like the 6809 were available.

I started writing about my interest in electronic since 1970. And in 1977 the magazine (Dick de Boer!) introduced me to the KIM-1, and that enhanced my joy with electronics with computing.
At the university in these days electronics and computer science also came together.

We have published many articles around the KIM-1. Alas in Dutch and only on paper. Published on this website, see the Radio Bulletin pages.

Many of the articles deserve a wider public, the KIM-1 and its clones are used by a broad international public.
So I started a new project: translate the articles to English and make the software available in assembler and binary format.

Write your own programs

Radio Bulletin September 1977

The most enjoyable work is of course writing your own programs, making the KIM I do exactly what you want. Now, programming is not that easy for someone who has never done it before. Especially at the beginning, the aspiring programmer works in such a disorganised way that in the end he no longer knows which instruction is at which address. It is therefore important to set up a program in a clear, orderly way and to write down every change. In this article we will use an example to show how this is done. However, we leave the exact working-out to the reader, because here too it is certainly true: practice is the best teacher!!!

Programming step by step

A five part article in Radio Bulletin 1978 to 1979
Since RB’s KIM campaign in August of last year, the number of KIM owners has grown considerably. Readers’ reactions show that some of the new KIM owners are already getting the hang of programming quite well. Another group, however, is clearly lagging behind: the people who cannot find the ‘beginning’. That is very understandable when you consider that, although the computer is built from electronics, programming is completely new territory for many. In this article RB will therefore try to help this group on their way.

Memory expansion for the KIM

Radio Bulletin 1977/ Introduction of the BEM bus with a 1K RAM card.

Although the 1K memory space of the KIM 1 is very generous for a beginning programmer, sooner or later the need for more memory will arise. This allows larger programs to be written, or more programs to be held in memory at the same time.
There are several ways to expand the memory. You can buy a number of ICs yourself and mount them on a home-made circuit board, which is by far the cheapest solution. The nicest solution is simply to buy a ready-made memory card; you then have a professional piece of work, with the reliability that goes with it.
A 1K EPROM card is designed, based upon the BEM bus.

EPROM Programmer

Radio Bulletin 1978 J.M. v.d. Peijl
The EPROM (Erasable PROM) can also be programmed by the user. In addition, it can be erased again using ultraviolet light. Thus an EPROM containing obsolete or outdated programs can simply be erased and reprogrammed. The most popular EPROM at present is the 2708 (1K byte), which has fallen considerably in price recently, partly because of its successors, the 2716 and 2732, with 2K and 4K bytes respectively. Programming such an EPROM is a task that the KIM can handle very well. In this first part you can read how, by adding a few simple circuits, the KIM takes over the job of an expensive PROM programmer. We will describe several practical versions.

Audio cassette recorder

Radio Bulletin March 1980

Accompanied by the slogan ‘Tophit 1980’, Radio-Service Twenthe is offering a built-in front-loader cassette deck for the low price of f 32.50. Radio-Service Twenthe often manages to offer interesting industrial surplus to the amateur at a reasonable price, and this cassette deck is another example of that. A handy tinkerer can easily turn this cassette deck into a mono cassette recorder; for personal computer users this is a golden opportunity to get hold of suitable cassette recorders with a tape mechanism.

Memory Expansion for the KIM

With 4K RAM card and busbuffer print.
Radio Bulletin September October 1979

Memory expansion for the KIM has already been discussed twice. The first time, in the November 1977 issue, it was shown how RAM could be added with the BEM-1 board, a kit for 2K of static RAM. The second time was in the July 1978 issue, when a board design for a 2K EPROM card was published, with the same bus connections as the BEM-1 card. This series now continues with a 4K static RAM board, also with the same bus. Connecting the RAM to the KIM requires address decoding and a bus buffer. A board has been designed for this as well.

Motherboard, memory support for 6502 systems

Radio Bulletin July 1981

Radio Bulletin has already described several ways to expand the standard memory of 6502 systems such as the KIM. Published so far are a 2 Kbyte static RAM card, the BEM-1 board (November 1977), a 2 Kbyte EPROM card (June and July 1978) and a 4 Kbyte static RAM card (September and October 1979). All these designs use the bus as used on the BEM-1 board, but with a number of additions, which will be needed mainly for the 4 Kbyte EPROM board in a forthcoming issue. This article describes a motherboard into which all these cards can be plugged.

The subject of this article is a family of parallel input/output ICs: the PIA 6820, 6821, 6520 and the VIA 6522. These are widely used ICs, and not only in 6500 and 6800 microprocessor systems. Besides the general hardware characteristics of the PIA and the VIA, a practical implementation is presented

4K EPROM card

Radio Bulletin September 1981

As part of further memory expansion for 6502-based systems such as the KIM, Junior, SYM, etc., a 4 Kbyte EPROM card is described here. It is suitable for two types of EPROM, the TMS2516 and the 2716, the latter being the most common. The board plugs into the motherboard published in a previous issue of Radio Bulletin. Combined with the EPROM programmer (RB December 1980 and January 1981), this gives you the tools needed to put programs such as an assembler, a high-level programming language, a bootstrap loader or your own developments into ROM and run them from there.

Graphical TV Display

Radio Bulletin, 4 parts, September 1978 – November 1978 – February 1979 – March 1979

Just imagine: an ordinary TV on which you can make your own drawings. These can range from plain text and graphical representations of mathematical functions to a drawing made by a toddler. For this purpose the TV screen has been divided into a grid of 256 × 256 dots!! Such a grid gives roughly the maximum resolution that can be displayed on an ordinary TV (without interlacing). The applications are countless. The computer hobbyist gets a particularly fine output device, a kind of combination of plotter and teletype. For those who do not own a computer, it is possible to expand this unit into a hobby computer.

Characters (Letters) on the Graphic Display

Radio Bulletin May June July 1981

In the previous series of articles on the home-built graphic TV display, a lot of attention was paid to the hardware of this display. Two important routines were also discussed, namely switching on or off one of the 65536 dots and clearing the picture. But… a display is not a display if no text can be shown on it. That is why this article presents what is perhaps the most important piece of software written for this display: ‘drawing’ letters, with unprecedented flexibility.

Graphical Display Monitor

Radio Bulletin 1981 – 1984 4 parts

The set-up is as follows. The complete package consists largely of subroutines that are controlled by a small main program. These routines are simply placed one after the other in memory. Those who do not want a complete monitor can use these subroutines separately, since they can also prove their worth on their own. This produces a “subroutine arsenal”. Those who do want a complete machine-language monitor, however, will have to make a few changes to, and additions to, the hardware.
1. As you may know, it is possible to build a hardware scroll-up on the GD. This needs 4 ICs. Without this extension the monitor does not work.
2. The monitor needs a larger keyboard (28 keys). I may assume, however, that if you do not have an ASCII keyboard you have long been planning to buy a more extensive keyboard. Further on in this article a keyboard is described that is very cheap and more than adequate (for about f 30.00 you have a well-working keyboard). A real ASCII keyboard is of course still recommended.
3. Not necessary, but very handy, is a circuit that allows a loudspeaker to be switched on and off by software. This can be useful in combination with the monitor (think for example of a beep after CRLF has been given).

Digiscope for 6502 systems

Radio Bulletin April 1983

Those who have a Graphic Display and a computer system based on the 6502 will discover in this article that the possibilities of this combination are almost unlimited. The January 1980 issue described a frequency meter, which once again showed that a computer can prove its worth in the hobbyist’s electronics lab. The program discussed here, as an addition to the frequency meter, will for many be an answer to the question: “Should I buy a computer?” What we have here is a so-called “digiscope”. This is a kind of oscilloscope that makes digital signals visible on the graphic display.

48K RAM card

Radio Bulletin 1982

If you want to work with Basic, Forth, editors etc., you need a lot of memory. It makes no sense to build this up from 4K memory cards. A cheaper and better solution is to use dynamic RAM ICs.
The industry-standard 4116 is a 16K × 1 dynamic RAM chip. With eight of these 16-pin ICs you get 16 Kbyte, and with 24 ICs 48 Kbyte. The dynamic RAM card for the 1802 fits into a bus connector of the Cosmicos computer. The card is also easy to use with other 1802 systems; it is then connected with 24 wires.
What is remarkable is the simplicity of the dynamic RAM card. This is because a special IC has been used for timing and refresh: the Intel 8202. Since this controller and the memory ICs functionally form a self-contained unit, use with e.g. KIM or Junior computers is certainly possible by adapting the addressing logic. You don’t need to design a PCB for that part – no small job saved.

48K RAM card Interface for the 6502

Radio Bulletin September 1983
After tinkering for some time with 4K RAM cards and the accompanying tangle of wires
and connections, my eye was caught by the 48K RAM card for the 1802 published in the
March 1982 and following issues of RB. This o%ered the chance to solve the memory
problem once and for all, so the possibility of adapting this card to the 6502 processor
was studied. By leaving a number of ICs o% the original board and adding a small
interface in the space freed up, you get 48K of RAM for your 6502 system – a real wealth.
