[GRLUG] Dear Builders & RaspPi people -Chips & Parts Available

[Adam Tauno Williams]

I assume the project-builders / Raspberry Pi people frequently have to
build some kind of interface circuitry beyond their little embedded
computers.... I have a large-ish collection of TTL logic chips for
someone working on a cool project; if you need some chips let me know
and I'll get them to you or arrange for them to be at the next social.

7400 7402 7404 7407 7408 7411 7412 7420 7430 7432 7438 7470
7490 74109 74138 74139 74161 74166 74240 74139 74161 74166
74240 74241 74245 74273 74373 74670 74688 74244 7474
* Various quantities of all the above, from one to fist-fulls.

4164 [64k x 1] & 41256 [256k x 1] D-RAM chips.

There are also Z80 CPU, DARTS, PIO, and CTC chips for those for whom a
pre-build embedded computer is simply too lame.

Several 2N3055 power transistors and some stout looking rectifiers [no
part numbers].

A couple of fairly string induction motors with sprocket drives; these
are pulled from big copy machines.

A shoe box of some big capacitors [I'll go through it for specifics if
someone is interested].

A Tecny Electronics [aka Tecel] MC200 - this is a 68HC11 based
microcontroller board [3"x3"] with 36bit IN/OU, 8 Channel 8 Bit A/D, 512
bytes of internal EEPROm, 8K EPROP, 32K SRAM, an RS-232 port, and runs
at 8MHz.  The two onboard sockets for adding addition EEPROMs are both
filled.  I believe Tecel [the company] is gone, but this is a nice
little controller.  I don't have a copy of the related S/Basic compiler.

A cast off FIRST gyro-chip by BEI.  Part number looks like PET-GF15, you
can possibly dig up docs via the FIRST web-site.
