Brutech BEM

A Dutch company, producer of many 6502 and more industrial hardware, BEM was the name one of their product lines.

Brutech Electronics Microsytems – B.E.M

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 CPUs like the 6809 were available.

Brutech sold the VIM-1 and SYM-1, with their cards as expansions.
Review in Radio Bulletin November 1978
Brutech sold also the PC100, the Siemens OEM version of the AIM 65. Again the expansions could be used, same bus.
Review in Radio Bulletin August 1980

B.E.M. SBC4D(2) 6809 based CPU card on the BEM bus

MAiS, a system for airtraffic control, developed around the BEM SBCD4 and a custom card.

As editors of the magazine Radio Bulletin we had many conversations with them and wrote articles about their products.

For the KIM-1 and SYM-1 they had many products, some based on the so called BEM bus (DIN 31 pin connector), some as addons to the 22/44 edge connector of the KIM-1.
I stilll own this 4K RAM card:

Corsham boards

AIM 65/SYM-1/KIM_1 expansion boards are still available: the excellent Corsham Technologies boards offer RAM/EPROM/I/O with modern SRAM (low power, low IC count) in kit or assembled format. Here are the boards offered, I use them on my MOS KIM Reproduction KIM and SYM-1 and AIM 65.

First the current available boards, later the older boards

KIM-1 RAM/ROM 60K board

This is a combination RAM and EPROM board with a fair amount of flexibility for adding more functionality to your KIM-1!

Fills in the KIM’s missing RAM from $0400 to $13FF, giving you 5K from $0000 to $13FF.
Has RAM from $2000 to $FFF7, selectable in 8K segments.
The top 8K ($E000 to $FFFF) can optionally be replaced with 8K of EPROM on the board (27C64 EPROM).
Includes the xKIM extended KIM-1 monitor by default.
The xKIM monitor has commands to load hex files, dump and edit memory, a memory test, plus commands to access SD card features from our SD Card System.
The extended monitor has vectors to command functions so programs written for it won’t break when new versions are introduced.
This board can be added to any KIM-1 system, but the easiest way to add it is with our I/O Board. This board comes with a ribbon cable that plugs right into the I/O Board with no mess. By default the DIP switches are set so your KIM will have 5K of RAM from $0000 to $13FF and from $2000 to $DFFF. The extended monitor is from $E000 to $FFFF.

KIM-1 I/O board

KIM I/O manual Rev C
Schematic KIM I/O board

The KIM-1 Application connector has a lot of useful signals on it and our expansion board makes them easily usable, as well as providing an RS-232 interface to the KIM’s serial port. The KIM has a 20 ma loop interface because that was the standard used by mechanical teletypes commonly used as terminals in the early days of the microcomputer revolution. Now we all have RS-232 ports on our computers and our I/O board allows a modern computer to connect to the KIM.
The expander plugs into the KIM’s Application connector. The lower left hand side of the board has a DB-9 connector that mates with a standard cable to a PC serial port.
Just above the serial connector are two standard 1/8″ inch audio connectors for a tape player; some people still like saving data to tape, just like in the old days. If both cables are out then the audio in/out lines are connected; this is perfect for running PLL adjustment programs. There is a jumper to select whether to use the audio high or low connections.
Above the audio connectors is the power connector with connections for +5, +12 (only needed if the cassette interface is used) and Ground. A filter capacitor is present to keep the voltages smoothed out.
Two of the best additions to this board are the POWER LED and KBD/TTY switch. A few people, myself included, have almost pulled board or made other changes while power was on. The handy LED provides an indication that 5 volts is present.
If you’re switching back and forth between the normal KIM KBD operation and using an external TTY device, there is now a small switch located on the board that is clearly labeled as to which position is for KBD and which is TTY.
There are various connectors and a set of switches provided for feeding the K1-K4 lines to an external memory board, such as our 4K or 60K memory boards. Each K* signal is individually selected, so if you have peripherals in any of the K1-K4 banks, you can disable any of those signals from going to the external board.
All of the remaining I/O lines are brought to a header for expansion.

KIM-1 6530 Replacement board

A very common problem with maintaining 40 year old computer systems is that some of the parts have not been made for many decades, such as the two 6530 chips on the KIM-1. Each contains several timers, 64 bytes of RAM, multiple parallel I/O ports and 1K of mask programmed ROM containing the KIM-1 monitor program. To make things even more complicated, each 6530 is mask programmed with a number of configuration options such as which interface pins and address lines select which internal devices.

Many people, Bob included, have at least one KIM-1 in their collections with a non-functioning 6530. Depending on what failed, the KIM might be quite usable, completely unusable, or someplace in between. For these people, there was little chance of ever fixing the problem because the two 6530s in the KIM are unavailable anywhere… not even on eBay! In an effort to fix his own KIM, Bob borrowed work of other people and developed a small board that can replace either 6530 on a KIM-1.
Basically this emulates the functionality of the non-functioning 6530 by using the I/O ports, RAM, and timers from the 6532 chip, and then having an external EEPROM hold the code that was in the ROM of the original chip.

The board replaced U2 (6530-002) on Bob’s KIM and produces a fully functional system again. This is a prototype board (strange board color) but is identical to the production version otherwise.

For full documentation, schematics, design files, Gerbers, EAGLE CAD files and other technical data please also see Bob’s development notes.

The assembled version is the quickest way, and the easiest. Just set the three jumpers to either U2 or U3 to indicate which chip you’re replacing, remove the old 6530, then plug in this board. Bob strongly suggest saving the original 6530 in case you ever decide to sell your KIM to a museum as a static display.

AIM 65/SYM-1 60K RAM

Basic features of the board:

  • Can be used on either a SYM or an AIM.
  • Memory selectable on 4K boundaries covering the entire 64K address space. Not all blocks can be RAM, as the SYM-1 already has up to 4K of RAM on-board, there are multiple ROM sockets, and I/O.
  • The top $80 bytes are not available; that area is reserved by the SYM-1.
  • Can allow space for BASIC or other software in ROM. My system has an 8K BASIC ROM so I did not place RAM at C000-DFFF.

The Rev 2 boards have an additional chip which works around a bug in early AIM-65 boards. We know the problem was in rev 1 and rev 0 AIM boards, and it was definitely fixed on rev 4 boards, but I don’t know exactly which revision fixed the problem. Basically the RAM_R/W signal (pin Z on the Expansion connector) had the inverted Phase 2 clock NAND’ed with R/W. The SYM and AIM were both supposed to follow the KIM standard, but Rockwell got this one signal wrong.
Rev 2 boards have replaced the jumpers with a pair of 8 position DIP switches; those are easier to set and there are no jumpers to get lost ??
When running the ROM BASIC, this is what gets displayed:




Here RAM is configured from 1000-7FFF, B000-BFFF, and F000-FF7F. That gives a lot of room to squeeze in useful add-ons to the monitor.

22/44 pin Extender Board

One side has a 22/44 connector ready to plug into your KIM or any other computer with 22/44 edge connections on .156″ centers. On the other side are the same pins for you to plug another board into.

In the middle is the cool stuff. All pins brought to a .1″ center header, and each is labeled so you won’t forget that some letters aren’t used ??

There are a couple of good uses for this extender. First, you can easily probe any signal between the KIM and add-on board. Nice. The other big plus is that it saves wear and tear on the edge connectors of the KIMs in our lab. They are almost 40 years old, so we try to be gentle on them.

SYM-1 1541 DOS

A DOS for the SYM-1, based upon the Commodore 1541 System

See also

The DOS was sold by Ronald A. Jordan in 1984, who sold this DOS thru his company, Jordan & Associates. This 1541 DOS system was sold as object code on a cassette tape. For an additional fee he would burn an EPROM as well as provide the object code on cassette tape and for still another an additional fee, he would provide the source code on cassette tape.
The 1541 physical interface was also provided by Jordan and consisted of a very simple box with one 7416 hex inverter chip with the mating connectors for the SYM and Commodore 1541 Disk Drive.
The Commodore 1541 disk drive was affordable, around $300 in 1983. A logical choice at the time therefore, since the serial IEC bus is so easy to operate on a small 6502 SBC and the whole DOS included in the drive itself, avoiding a DOS for the SBC. Disadvantages of course are the slow IEC bus and nowadays the vintage character of the 1541 drive. Since there are alternative ‘1541 compatible drives made by hobbyist, with an SD as storage it is still interesting to add this to a SBC (SD2IEC, Pi1541 etc).

On this page all available information is collected about this 1541 DOS.

The information on the 1541 DOS is from these websites:

Added by me are the sources of the 1541 DOS, the scanned version was lost long ago on teh page of Dallas.. But I did keep a copy. In 2006 the source has been typed in by me in normal 6502 assembly.

The 1541 DOS package consists of a manual, a tape with 1541 DOS code and optionally a hardware interface tot the IEC of the Commodore 1541 and also optional source code on tape.

The 1541 DOS code is made up of interfacing code for the IEC bus, and integration for the Monitor, Basic and RAE. The fuctcionality is limited to showing directories, loading and saving memory, but no data file support. It ix possible to give to the 1541 drive ‘special’ commands, e.g. format a drive. More than one drive is supported.


The interface is simple, just an open collector TTL IC, 7416, 3 inputs and 3 outputs of the VIA 6522 to the IEC serial bus ATN, DATA and CLOCK and RESET

Part is interface to the IEC bus (bit banging), the other parts are linking to Monitor, RAE and Basic.

New SBC: SYM-1

I have acquired a SYM-1 Rev 1.1. Again a historical milestone back in my collection.

It works, so much more advanced software than a KIM-1, with more I/O and 4K memory.

No Basic or RAE ROMs alas.

See the Synertek SYM-1 pages for more info.
