NANOKIT and other SC/MP stuff

NANOKIT: My first computer. You've probably never heard of this -- it was produced locally, in the mid seventies I would think. I got hold of mine somewhere around 1979, second-hand, from Capetronics (an electronics store in Bellville).

Intel SDK-80

My Intel SDK-80 came with a set of ROMs (two 2708s) with Tiny Basic on them, which I've never tried. I've dumped some of it (back in the eighties, by hand, using my MEK6800D2), and it seems to be a copy of Palo Alto Tiny Basic, which you can find at http://www.nicholson.com/rhn/files/tinybasic.tar.Z, or here (local copy).

MEK6800D2 and MEK6802D3

I got the Motorola 6800 D2 evaluation kit from Jacques, a radio amateur who lived just around the corner. Later I bought a MEK6802D3 with peripheral boards from Capetronics, they got a whole bunch surplus from maybe UCT. And even later I inherited Barney's MEK6802D3 system.

I spent a large part of my youth playing with my UNITRON Taiwanese Apple ][ Europlus clone. These guys were apparently not related to the Brazilian Unitron. I would hazard a guess that most Apple ]['s sold in South Africa came from Taiwan.

An 8-bit passive ISA backplane 8088 semi-IBM-PC computer, here

ICL Personal Computer

This is NOT an "IBM PC", but some kind of a passive backplane machine with four serial ports and no video.

Work sort-of in progress, maybe

NCR Core memory

I can't remember where I got this... some junk box at an electronics store, probably. I think it's from a cash register or something. One bit per ferrite bead. But, it will probably survive an EMP, so if there's something you need to store until after World War 3, this memory's for you.

The sticker on the bottom reads


P/N 095-0008708
S/N 3962
8 May 1974

The core array is 64 x 64, i.o.w. 512 bytes. There's also one core located off to the side, (You can *just* see it on the top righthand side of the fourth picture) I don't know what its purpose is.

During a discussion on the Classic Computer mailing list, I scanned an article, Coincident Current Ferrite Core Memories, from the July 1976 BYTE magazine. A while after that, Jim Jones, the author, contacted me. Read more about it here.

You can also download the complete July 1976 BYTE from http://malus.exotica.org.uk/~buzz/byte/pdf/.

A good description of core memory by Brent Hilpert.

The Casio AL-1000 uses core.

Bubble memory
