622.0. "Logic Analyser" by SUBURB::JAMESH () Tue Oct 03 1989 04:51
In the October 89 issue of Elektor magazine (UK) there is an article
about a logic analyser for the ST. Here are the details:
Hardware:
8 TTL Channels, 2 Mz sample frequency, 31 kbyte memory,
selectable sample rate, External clock input,
External trigger input, Selectable trigger polarity,
Connects to ST DMA port.
Software:
Data read after triggering, Selectable trigger polarity,
6 scroll speeds for data window, Zoom function
Pulse timing with cursor counter, Disk storage/retrieval of samples.
Chips used are 74HCT series: 74, 04, 32, 86, 4040, 4051, 245, 375
plus a 74121 and a 7805.
A PCB is available for 5.25 pounds and the software for 10 pounds.
Unfortunately there is no listing. Sounds nice. I shall wait a couple
of months for any amendments then go for it.

Cheap enough, but 2MHz isn't very impressive.
That's 500 ns per sample. Any information that
it could be sped up?
