I remember ~10 or so people got nice cheap mostly working Heathkit 3400's at VCF 10 last year. Anyone do anything with theirs? Someone today sent me a question through my web site about terminal settings for the 3400 monitor program, I pulled my 3400 system out and fired it up to test and confirm mine is 2400 7/n/2 -- Bill

Was it Andy Welburn who asked you? Or someone else? Andy has been working in the past few weeks restoring and fixing/repairing an ETA-4000 (the rs232/BASIC/monitor add-on module for an et-4000) which was missing among other things both of the code ROMs and even the address decoder prom! He was able to figure out the prom contents based on the eta-4000 manual and schematics, but still could use a dump from an actual ETA-4000 to ensure that his guessed dump is correct. -- Jonathan Gevaryahu jgevaryahu@gmail.com jgevaryahu@hotmail.com

Yup. We had a few back and forth messages. I offered to dump RAM but I guess he got what he needed elsewhere. Anyone else? I exhibited mine at VCF 2014 b

I own an ET-4000A (the 'later' 6802 based ET-4000), but not from vcfe. I don't own the ETA-4000 addon, though. And the dipswicthes on the ET-4000 have been 'studented' half to death, so I should probably replace the array. Does anyone have the "Speech Synthesizer" addon 'lesson' binder and chips for the ET-4000? If so, please contact me off-list. -- Jonathan Gevaryahu jgevaryahu@gmail.com jgevaryahu@hotmail.com

Sorry, I keep calling it ET-4000 or ET-4000A or ETA-4000; the correct names are ET-3400, ET-3400A and ETA-3400. Sorry again! -- Jonathan Gevaryahu jgevaryahu@gmail.com jgevaryahu@hotmail.com

I have a couple of ET-3400s, but I've never been able to get my hands on one of those wonderful expansion units. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Anyone use the cassette for storage and retrieve their program successfully? I saved a Tiny BASIC program to tape and that's as far as I took it. Andy Welburn was asking me about my success with tape storage, but I did not have much to add other than what the manual says. Bill Degnan twitter: billdeg vintagecomputer.net
