For those who haven't seen a KM11 in action, I've updated the page to
contain a couple of shots of two of my KM11 clones plugged into an 11/40
while I was running some memory diagnostics. The display was quite
impressive but I couldn't capture it. :-( You'll just have to get a
couple and try it yourself! :-)

I was interested to see someone still interested in the Old TI 990/10 & /12 system. I worked for TI from 1980 to 1986 and worked with the 990/10, 990/12 & Business System 1300 & Business System 1500. I started my company in Austin, Texas, building performance products for the TI Systems. We built memory expansion boards, 8 Port CRU Devices compatible with the CI-402,
8 Port & 16 Port Ti-Line devices compatible with the CI-403. We also built "Turbo" upgrades for the 990/10A as well as the fastest
memory controller to ever be used with the TI 990/12 and 990/12A. The Memory Controller could be configured as 512K., 1 Meg.,
1.5 Meg. and 2 Meg. It was totally Static Ram, ( no hesitating every 14 to 15.5 microseconds for a refresh cycle.) The static
ram on our board ran at 35ns and the fastest boards ran at 25ns. ALL CACHE MEMORY. The controllers sold to dealers for
$15,000.00 ea. At the request of John Deere, TI supported our 8 Port Terminal Controller under Maintenance Contract. We also
used to do fixed price repair on all TI Computer Boards. We also performed Memory Upgrades to the TI 512K. LR Cache controller boards. We could upgrade them to 1 Meg. and 2 Meg. of Dram. The 990/10A was sold as 512K, 1 Meg. and 1.5 Meg. but
we could upgrade them to any of those sizes as well as to 2 Meg. We designed over 20 products to work with the TI Systems.
I really enjoyed working with them. Nothing since has interested me as much.
Sincerely,
Marty

Greetings!
I am an IT Director for a central Illinois school district and we recently
uncovered a Mathiputer while going through old boxes of electronics
equipment from the 70s and 80s. Do you have any info about the Mathiputer
or even if the company is still in business? We want to tinker with it and
give it to a teacher as a gift... and a joke.
Thanks much,
Chris Kruzic

Hi Tom
It was either loan.com or loans.com that he sold. It is
probably more interesting to here his story as to how he
got the .com name in the first place. You know, failed
business plans and then forced on him by the wife of his
business partner that felt he was responsible for the
business failure.

His name might be Marcelo.

Hi
I'm not sure if they had the same reason but today,
DC is actually used for long range, high voltage lines
in a number of places. DC doesn't require the insulation
to hold off quite as much voltage. It doesn't suffer
>from inductive losses.
It isn't much good for home use. In fact, lamps don't
do as well on DC as AC because of the electrical effects
of the wire evaporating ( not sure which end goes first ).
