Including the microcode to do that by 1985 was part of this roadmap. . .for a 5x speed improvement to GPL and BASIC execution times. It is also interesting to see that they figured they had better have a better grapics processor with more memory/sprites per line in place by 1983. . . 1 Quote Link to comment Share on other sites More sharing options...
+acadiel Posted January 18, 2021 Author Share Posted January 18, 2021 This is a 1981 packet (with some information you've already seen, and some new stuff). It's from the "Mechanization Department" at TI - and it's the Preliminary Design Review for the ALC (which became the CC-40.) Again - lots of duplicate material, but I'm presenting it as it was stapled together in this packet. 1981-ALC-Consumer_Mechanization_Dept_Prelim_Design_Review.pdf 3 Quote Link to comment Share on other sites More sharing options...

+acadiel Posted January 18, 2021 Author Share Posted January 18, 2021 Last part of the "ALC Development" folder. Onto the next one. This is the June 1982 21-page whitepaper about the Lonestar Microtape Mass Storage Peripheral Power Analysis. Using the Lonestar Intelligent Peripheral Bus. (Otherwise, known as the CC-40 Wafertape mass storage drive using Hexbus.) I really want to see Omega make a "Lonestar" CC-40 logo. That would be really cool. 1982_June-Lonestar_Microtape_Mass_Storage_Power_Analysis.pdf 3 Quote Link to comment Share on other sites More sharing options...

Well, another funny thing I found in that is that they wanted to replace the 9900 with the 9985 still - to replace "9900 plus 9 LS chips". Did the 9900 support circuitry really need 9 support chips over the 9985? Any hazards to why? Quote Link to comment Share on other sites More sharing options...

Wouldn't be needed for the 8-bit external data bus 9985. Quote Link to comment Share on other sites More sharing options...
+FarmerPotato Posted January 19, 2021 Share Posted January 19, 2021 Also integrated would be the 2x128 bytes RAM and TIM9904 clock phase generator. 3 chips there. I guess. That’s what the 9995 has. Quote Link to comment Share on other sites More sharing options...

+acadiel Posted January 30, 2021 Author Share Posted January 30, 2021 This looks to be a pretty-close-to-final set of LCD specifications for the ALC/CC-40.

LanceLHall Posted February 1, 2021 Share Posted February 1, 2021 Thank you for taking the time to do all of this. You should also copy all this to a public shared folder on Google Drive which is free if you or anyone else has Gmail. Quote Link to comment Share on other sites More sharing options...

I've given a couple people access to my personal OneDrive share to mirror what I'm doing as well. Thirdly, I've given access to the TI Corporate Library at SMU so they can also archive these documents. 2 2 Quote Link to comment Share on other sites More sharing options...
