View Full Version : Intel ICE-80 board pair (Intellec bus)

I recently got hold of the pair of Intel ICE-80 boards, much like the ones pictured on this page: http://www.classiccmp.org/hp/multibus/multibus.html

I'm curious to see if there is any interest in this kind of development gear at all. At the heart of the system is an 8080, with 256 bytes of RAM and 1K of ROM. Apparently it also shares the memory with the host computer. Not too much, and not too usable unless you got an actual Intellec system like the MDS-800. I don't got any of the breakout stuff, nor do I got hold of any software.

The iLBX bus (Intel Local Bus eXtension) was developed by Intel in an effort to overcome the bandwidth limitations of the main (Multibus) bus, particularly in multi-processor systems or systems with lots of I/O. Their intention was to give each CPU it's own local bus for things like I/O and some amount of local memory. The physical characteristics, handshaking, electrical loads, etc are all specified by the Intel iLBX Bus Specification 145695 Rev A.
