The Humming board is an 80386 with 16 megabytes of memory and "special" hardware additions, apparently to do typechecking. It is a "coprocessor" board, with a price around $7,000. It is available from Gold Hill and runs their Development Environment. It is said to provide a speed improvement of a factor of 2 over an AT. Jeffrey M. Jacobs CONSART Systems Inc.

Sounds like it should be more like 10. Any of the features you mentioned (386 instead of 286, 16 meg memory, hardware type-checking) should contribute at least a factor of 2 in performance. If it's really a factor of two, they must be doing something seriously wrong... Arpanet: yoram@cs.columbia.edu | Columbia University Usenet: seismo!columbia!cs!yoram | 450 Computer Science Bldg.

Jacobs I believe Golden Hill says the speed improvement factor is about 5. That makes it run about as fast as a Symbolics, I believe. -dan costin

The Gold Hill data sheet says, "This new system performs up to five times faster than the PC AT-based GCLISP 286 Developer, providing an attractive PC alternative to LISP machine development." (note: GCLISP 286 Developer is a Gold Hill product). The Hummingboard holds 6Mbytes of RAM (and can be upgraded to 24Mbytes when 1Mbit DRAMS are available (I was told the board uses DRAMS in SIP packages so that may affect availability and cost). The data sheet also says, "The HummingBoard supports the Intel Above-board standard, allowing users to run large EMS standard programs on their 8088 or 80286 processors accessing the 386 HummingBoard's on-board memory." I'm not sure if this means that the HummingBoard can use the EMS memory for lisp. I can only pass on what I've read in their brochures and from talking to someone there. I would certainly like to hear more from anyone who is actually using the HummingBoard. -- Jeff Kitson jeff@kestrel.arpa

The Humminbgobard only has 1 megabyte, and I cnanot confirm type checking hardwawre.
