Sigh.. and here I sit, yet again, with neither a logic
analyzer
I've bought Tek 1240's (which are really nice units, although of course
without the capabilities of today's - but still a lot more powerful than the
earliest LA's) on eBay for as little as $25 (albeit without leads), and I
gather there are modern units which plug into a PC with a UCB port for not
much more money.
Yes, a lot of the older machines were built without benefit of them (pretty
much all their builders had was 'scopes), but there are so many things where
one cannot easily create a 'scope loop, and for investigating those, a logic
analayzer is the perfect tool.
It's just a critical tool to have if one is going to _repair_ old computers -
only slightly less critical than a VOM. No ifs, ands or buts.
