above - I see sev. ways to interpret yours, as in ..iam_Ox... but not ..iam Ox.. but maybe --> ..iamOx..
I'll ponder on a mainly demo for kids, but best let me know what other use you might have in mind. BW goes from teeny handheld 500 KHz -- on up. Have some needing minor fixing, thus for rilly cheap. All good lab-grade Tek, some HP, no TV-tech type beaters. Even teeny 4 MHz w/ batts. Cute but jeweler-hands needed. Should see the gold plate in such as the 335 (a Sony-Tek venture in '70s).
(What's amazing and of course depressing too - the occasional near-mint super lab-grade 7000 series (plug-in mainframes + beaucoup speciallized plug-ins).. going for <10% of last new cost.) Indicates to me that we are losing that always small part of population - who even know what to do with such equipment. They don't build kits; dunno how most stuff works.. and don't wanna know. They buy. Then toss, all unCurious.
Supply/demand in a dumth-increasing, MBA PHB culture - focussed exclusively on boring bizness. Our techno must soon reflect this absence of new talent, new explorers.
No more Numbah One, 'cept maybe in Reality Tee Vee games.
