@@1971merlin Specially made for capsizing them

nice! That's a great idea for a project too, since you get an actually-useful thing out of it at the end

It is late Ron Crane’s databook. The co-founder of 3Com, and designer of one of the first (the first?) 10Mb Ethernet interface, once Ethernet got standardized after the experimental 3Mb Xerox Alto. Great things were done with that book. See Ron in this video: kzfaq.info/get/bejne/js55osuI15eUm4k.html

I inherited the same TI book from a guy who worked for Ampex for decades. I also was given his mint condition Zenith Z-159 with all manuals and original brochure from when he purchased it in 1979. I still use his tube manuals and TTL books in 2021!

@@CuriousMarc I got mine from a teacher that was throwing it out. I was like is that literally a hardbound TI databook I'll take that and he's like but it's garbage but okay lol

I just thought of the same thing - my concept for now would be to use an AVR-microcontroller with enough digital pins (not a master-slave construction as the one Marc had) and two 16channel analog switches. A possible platform could be an Arduino Mega, but I would probably not use the Arduino framework for my project

@@uwezimmermann5427 I think I will use PIC18F87J50 as in the TL866. The cost of the chip is cheap, only 4 €. My concept is to create a PC interface connected by USB cable. The data sent to the PC will be processed by software or vice versa. In this way I will have to enter the parameters of the chips only in the sw. Currently not all power pins are connected to the ZIF. This limits the number of chips I can test.

@@leonardochiruzzi7642 I am not a PIC-fanboy and more than just happy that Microchip even started to release new AVR chips since they have swallowed Atmel for its ARM-license. I tell my students that once they know how one microcontroller works they will be able to use almost any microcontroller, but I'll stick with my AVRs for now 😎

Oh boy that keyboard was hard. It’s still waiting for some unusual chips.

Was it a Watford Electronics Adder? I've got one of those.

you have a link to the software?

Ohh yes. Stick a Teletype on that tester ❤️

I was going to, but it uses VT100 escape codes to do the highlighting :-( . I need to ask for a special TTY and HP 2645 compatible version!

@@CuriousMarc no one that has a DEC VT100 ?

I found your video kzfaq.info/get/bejne/ftt_e8Zzppilo2w.html

link to @Michael Benn ‘s tester video: kzfaq.info/get/bejne/ftt_e8Zzppilo2w.html

@@CuriousMarc Oops, I should have included the link myself! Thanks Marc & Nuts - odd way to put it I suppose ;-)

Ooh, aah! Nice vintage unit!

I'm lacking the white coat so guess I'll settle with the automated tester.

You deserve to win a vintage TTL circuit, guaranteed broken as proven by the Tauntek!

@@CuriousMarc I think I'll pass (or , should that be fail?)

Later it became known as the Texas Instruments TTL databook I think. An oldie but very goodie.

Et merci pour le remerciement!

It helps in aligning the electrons better, they don’t get disoriented.

Older terminals used a limited screen resolution because the bitmaps for the font had limited memory, usually a 6 by 8 bit font.

@@acmefixer1 it's a Windows terminal though, they can use any font they like. It seems to have a scanline effect applied that makes it look bad on a 1080p TV.

Alternatively show it connected up to to a HP 2645A.

Thanks for the offer, but I got some from Marcel already. Marcel has everything…

I jury-rigged surface mount RS-232 connector, which is kind of acrobatic and not recommended. I believe the board was made to use one of these old cables that used to go to RS232 ports from motherboards on PCs.

I ended up doing the same. I could not get my hands on the old PC cable that was intended to use with the 10 pin header connector. He should just design the board to just solder on a female DB9 connector so a USB to serial cable can just connect directly instead of a mess of cables & adapters just to finally connect. Those old PC cables are hard to locate when you live in an area with zero electronic stores. Even the thrift shops no longer have the once piles of PC junk parts.

@@glennbruner7504 Yes I suggested that too.

Yes, apart from some NVRAMs it can only test a few, but very common SRAMs - like the 6116 oder the 6164, for example. It's a really good product, still getting updates (with more chips supported) -- especially considering the price!

v11 works only with a more recent TL866II Plus.

I've done pretty well over the years with a SIGNIFICANTLY dumber tube tester... a.k.a. ME 1: If there's cracks in the glass or the mirror-like getter flash looks like powdered sugar, straight into the bin 2: Does the 'pilot light' (filament) turn on - if not, check filament voltage and, if present and correct, throw it out. 3: Does the big black metal thing inside (plate) look like it could fry an egg from 50 feet. If so, disconnect everything from the associated grid(s) and retest. If it's still hot, place gently in file #13 and install another. If it's NOT hotter than Mercury with the grids disconnected, replace all the leaking coupling capacitors Rinse and repeat

I thought so for a second, then realized that would be waaay too much current for an S too! So it’s really toast.

The Main purposes of the GUI and the Device is not to test Chips, rather to write to eproms. It probably cant eben thest the things that the other can. The other one is dedicated to Chip testing as is built for this.

The Tauntek tester only applies power when you do a test, otherwise everything is electrically isolated

So does the TL866 btw

Tauntek Logic IC tester is great for logic chips, when you want to see the specifics of how the logic chip behaves. The retrochip tester does a basic pass fail vector test like the tl866, so less info on logic test. The retrochip tester is great for testing memory ics. I use both regularly.

Hmm. Not really, that's the one I use to talk to him.

Maybe you entered a capital i instead of a lowercase l?
