If you want minimal, check out the Jr layout. Wow! (From Cameron’s site)

@HOME AUTOMATION is gonna love this one. The 1978 specifications for the Home Computer Security System (over 100 pages!) I whitened it, de-skewed it, and it was good enough to apply OCR, so it's searchable. Enjoy! 1978_Home_Computer_Security_System.pdf

I'll scan everything that I have. It'll all go up here first, and then I need someone's help with renaming it all, sorting it, and uploading it properly to WHTech into the right spots. Also, now that we have people taking my "whitened - deskewed scans" and applying OCR, we need to figure out which ones of these should be chosen as well. While I appreciate everyone helping out with the OCR - and it's good that a few people have done so - let's coordinate who's doing OCR and figure that out so we don't have a lot of different things to worry about choosing from. Maybe an "OCR" thread to separate it all.

I’ve been using Abbyy Finereader - so the deskew and whiten work extremely well. The OCR - not so much.

Merci, humeur! I am simply de-skewing and applying whitening to the scans. Hopefully, this is cleaning them up and making them usable - but thank you for doing this!

Right now, I’m just scanning them. I have a lot more to go. OCR is a whole next level of difficulty. I am scanning them at 600-1200 DPI, so someone is welcome to OCR them to help out :-) Notice I haven’t put them on Whtech yet - I want them properly named and organized (and maybe OCR’d) before they go there.

Bill, @FALCOR4 is here on the forums and can likely help troubleshoot your GK. We also have the test utilities (burn in) that I uploaded to Whtech that can help diagnose what’s malfunctioning.

We have the test utilities and such now to verify the GK operation on Whtech. I thought that the disk image of the utilities was there as well.

Amazing how little current the Tutor draws.

Last one for today. How about the 1983 Power Line Network Design Specification? Designed about the same time TI was pulling out of the home computer market in late 1983. 1983_Power_Line_Network_Design_Specification.pdf

A 1977-1978 planning for a "Project X" LCD calculator with ROM cartridges and a data bus. Anyone know what this is? 1978_1979_LCD_CALC_Product_X.pdf

This goes along with @Toucan's pamphlet that he posted earlier this year from CB - it's a TI planning document. Enjoy. 1977_Strategic_Planning_Conference.pdf

Did you see the other thread? 🙂

Excellent work! Let me know when you get the Japanese BIOS and Japanese BASIC that I sent you. Would be interesting to see if any similarities exist.

In Fall 1981, TI had solicited list of programs that users wanted for the TI-99/4. Here's the PDF of everything requested. 1981_Program_Requests_TI994.pdf

I need to burn a new image today. I was like .7 versions behind and went to update, and it tried all day. Thanks for the heads up - I’ll just set it up again.

Answered my own question above about the contents of the Cartridge adapter ROM. The Pyuuta boots up fine without the internal 16K rom if you have the cartridge adapter plugged in. Both JP and US BIOS. This means that the second half of 32K of the 27512 has both the JP BIOS and JP BASIC on it. Otherwise, the system wouldn’t boot without the internal rom inside. And yes, if you take the internal ROM and don’t plug in the replacement, the SN74689 remains uninitialized, a sound very familiar to us.
