In mid 1986, there had been articles about some kind of a monochip called 68070, done by RTC-signetics, with : CPU 68010 + MMU 68910 + 2 DMAC 68430 + 1 ACIA 2641 + timer 68230 + bus I2C interface (100 Kb) Do you know of any firm or lab which have done an evaluation board or a small computer with this device ? articles are : electronic design, May 1, 1986, page 229 minis et micros (french magazine) No 256 ___________________________________________________________________________ DESPOIX Frederic, despoix@imag.fr Laboratoire de Genie Informatique despoix@imag.UUCP Grenoble, France uunet.uu.net!imag!despoix

I spoke with the designer of the 68070 and he told me that Motorola is totally uninterested in the 68000 market now, and prefers to concentrate on the 68030/88000 style ultra-high performance CPU's. They just aren't interested in 68k style controllers for toasters and microwave ovens. Jonathan A. Chandross ARPA: jac@paul.rutgers.edu UUCP: rutgers!jac@paul.rutgers.edu

We have a very large design program that we call CORES which is basically a CMOS 68000 surrounded by various standard functions: DMAC, DRAM controller, timers, chip selects/ interrupt controllers *and* ASIC gates. We fully intend to explore the higer end controller market (from low end laser printers to VCRs etc -- not toasters). the 68070 was not picked up by Moto because it does not have the performance needed for some of these applications. The 68070 is not a 68k inside, it only has one 32-bit ALU that is double pumped. Take a look at the instruction timing versus the real 68k. -- Motorola Semiconductor Inc.

Chandross I think it would be a much better to ask a Motorola sales or marketing representative rather than an unbiased :-) designer of the 68070.

I guess I better tell the circuit designer next to me to find a new job. :-) Mike Schultz Motorola, Inc. Speaking for Motorola is not in my job description, but speaking for me is!

Chandross >ARPA: jac@paul.rutgers.edu >UUCP: rutgers!jac@paul.rutgers.edu With all due respect to whomever it was you talked to: Motorola has absolutely no intention of dismissing the MILLIONS of 68000's it sells. You should be hearing something in the (relatively) near future about Motorla's plans along the lines of the 68070. tomj@oakhill ------ |Disclaimer: I speak officially for only myself.
