Someone just posted this handbook on the Heathkit listserver, and looks pretty good at a first glance. DEPARTMENT OF DEFENSE HANDBOOK FOR STORAGE SHELF LIFE AND REFORMING PROCEDURES FOR ALUMINUM ELECTROLYTIC FIXED CAPACITORS It is online in PDF format at: http://www.multi-volti.com/hb1131.pdf

Do you mean Richard Stallman of GNU fame? If so, what's so bad or contageous about him? While it's well known that I'm quite disapproving of GNU (which is strictly because GNU is anti-UNIX and I'm well known to be a priest of Holy UNIX), I have nothing against RMS personally and I'm quite shocked to see people make comments concerning him ("sterilize the keyboard" etc.) that one would expect to be made about, say, Dark Emperor BillG.

rarest computers. was: RE: Xerox Alto Restoration + Emulation

by dwight.elvey＠amd.com

Hi ben A good picture of it can be seen at: http://www.omahug.org/vcf40/v02.jpg ( the Wyse terminal is not original ) It was used as a processing unit for a nuclear magnetic resonance spectrometer. This did chemical analysis. The upper part of the panel is related to the data acquisition while the lower part is the blinking lights part. Mine has 12Kx20 of core but they also had a 24Kx20 setup with an expansion chassis. The 12K core comes in 3 stacks. Most used a hard disk but mine is floppy bases. I'm always looking for more programs to run on this ;) Sellam has another one of these and there is a fellow in England that has one as well. These are the only remaining machines that I am aware of. These were in competition with the Varian machines of the time. Nicolet was one of the last manufactures to make core bases processors and made processors for use on subs because of cores resistance to radiation. The instruction set is funny as well. It used the typical conditional skip instruction of the time but the ALU was interesting because it used a 5 port input. It has hardware for doing multiply and divide because it's primary output was the result of doing FFT's on the data input. Fast multiply and divide are desirable. I have running a BASIC ( with matrix operations ), an assembler, an editor and several games. I also have a floating point package as well and some diagnostic programs. Any more specific questions?

How about replacing a card costing $25 to $50, vs. replacing the fried surface-mounted ASIC (one of only two or three chips on the card), which incidentally is only available to OEMs in the first place? In order to make mass-market electronics so cheap, they have had to be tailored to large-scale industrial producers, rendering them inaccessible to mere mortals. To take one extreme example, the single IC of modern calculators isn't packaged at all in the conventional sense--the chip is mounted right on the printed circuit board and encased in a blob of resin to protect it. And, of course, the logical conclusion of integrated circuit technology is to get rid of the circuit board and separate components entirely. Colin

Zilog Z8038 Z-FIO document available

by dwight.elvey＠amd.com

>From: "SHAUN RIPLEY" <vax3900(a)yahoo.com> > >I copied the Z8038 part from the book "The Z8000 >microprocessor, A design handbook" by Bradly, K. >Fawcett.

Thanks. > > Hi Shaun Does your book describe the floating point processor ( that was never released ). I was wondering because the CP/M-8000 that I've been playing with ( accually the C compiler ) uses the floating point processors instructions and then exception traps them to execute the floating point code. The format for using these traps would be the same as was expected for the real FPU. Dwight
