(6303, 6309 and 68030) and I find the trusty old Tek 465 o-scope is no
longer compensating for my lack of design skill (or I'm getting better at
hiding bugs in my designs, depending how you look at it). I'm looking for
a recommendation for a logic analyzer. Considering my very modest design
constraints, I'm thinking:
- Suitable for 50MHz designs (really more like <16MHz, but you never know)
- 32 channels would be nice, ~128 probably perfect, less...you know...do
what you gotta do...
- No weird technologies in the design (all TTL/CMOS logic)
- I'm willing to spend a few $$ to get decent kit, but need to spend closer
to 465 money than TLA7012 money
The Tek 1240 should work. If you want disassemblers, you need to look
up whether those specific CPUs are supported, but many of the common
ones from that vintage were available.
Probably not 68030, though.
The DAS9200 is a lot more capable, but had several different families of
acq cards, and some used different (incompatible) pods for the CPU
connection.
There's also the TLA 710 /TLA 720 series that are basically DAS9200's.
These are often cheap on eBay. They are able to be connected to the
net, and you can access them from a Linux PC.
