I got the MCF5206 Coldfire evaluation board SBC5206 ( today: M5206AN ), for about 100 EUR, a special offer, called “M5206PROMO”, valid until 1997-06-10, bundled with a complete software package, as mentioned below. I will tell my experiences with the processor, this board and the software on this WEB site.
Here is a list of useful documents to order for COLDFIRE users:
MCF5200PRM/AD | COLDFIRE Programmer´s Manual |
---|---|
MCF5206UM/AD | COLDFIRE User´s Manual |
MCF5206/D | MCF5206 COLDFIRE Integrated Microprocessor 96 |
MCF68HC901UM/AD | MC68HC901 Multi Function Peripheral User´s Manual |
For comparison, You should cross-read these documents, too (e.g. if You would like to know about the exact differences in the exception vector assignments or between the opcode sets):
M68000PM/AD | M68000 Family Programmer´s Reference Manual |

M68000UM/AD | M68000 8/16/32-Bit Microprocessor User´s Manual |
M68000UMAD/AD | M68000UM/AD Addendum |
M68020UM/AD | MC68020 Microprocessors User´s Manual |
M68040UM/AD | MC68040 Microprocessors User´s Manual |
I/O channel (8-Bit), soldering side | B3 | +5 Volt |
---|---|---|
B5 | -5 Volt | |
B7 | -12 Volt | |
B9 | +12 Volt | |
B29 | +5 Volt | |
I/O channel (16-Bit extension), soldering side | D16 | +5 Volts |
As a bonus, a NE2000 compatible Ethernet network adapter KNE 2000 TLC by KINGSTON is supplied with the MCF5206 COLDFIRE evaluation board SBC5206 ( today: M5206AN ). It may be plugged into the 16-bit ISA-BUS compatible slot. It needs +5 Volt for power supply. For this card only the operation is guaranteed in the ISA-BUS slot.
Unfortunately for me at that time, in the late 1990th, the network adapter is just equiped with a jack for the 10BaseT unshielded twisted pair wire. I finally found another NE2000 compatible card for which a +5 Volt power supply is sufficient and which operates in the COLDFIRE board !

Comment of KINGSTON about direct connections by a 10BaseT twisted pair wire: “If you are connecting two machines together using RJ45 cabling only (no hub), make sure your cross-over cable is built correctly, crossing pins 1&3 and 2&6. Even though pins 4,5,7, & 8 are not used, it is mandatory that they be present in the cable. (NOTE: A cross-over cable is necessary for connecting PC to PC, or hub to hub, unless your hub has a built-in cross-over switch on one of the rear-panel ports)”.
If you need more than one ISA-BUS slot for development purposes, then please have a look at these ISA-BUS slot extenders:
In general, “Riser Cards” are provided for free with “Pizza Box” alike flat network pc cases !
I am still looking for a suitable box for the Coldfire Board !
The ATARI_ST is equipped with the same i/o chip (e.g. the 68901) like the COLDFIRE board .
