+acadiel Posted December 11, 2020 Author Share Posted December 11, 2020 This appears to be a cartridge adapter pinout to plug in an EPROM programmer or simulator to the CC-40. "Programmer plug" is on the left and "CC-40 Cartridge socket" is on the right. This is dated May 1984. CC-40_Cartridge_Adapter.pdf 4 Quote Link to comment Share on other sites More sharing options...

+acadiel Posted December 11, 2020 Author Share Posted December 11, 2020 This one is a schematic for 2 16k x 8 or a 32k x 8 CC-40 ROM module (selectable), dated Feb 1983. Just to give you an idea of how much cleanup these take - I left the original as page 1, and then show you the cleaned up version (page 2), which takes quite a bit of manual touchup (the only thing I can't do is redraw some of the lines that are missing).

+acadiel Posted December 11, 2020 Author Share Posted December 11, 2020 Pictures of the first ALC, which was later designated the CC-40. Also, three prototype concepts for the ALC (see the ALC market study). The RM-1000 (entry), RM-2000 (mid level), and RM-3000 (deluxe), as well as proposed accessories for each model. Note, the 3000 had a tilt screen. 2 Quote Link to comment Share on other sites More sharing options...
+acadiel Posted December 11, 2020 Author Share Posted December 11, 2020 Concept drawings of the RM-1000, RM-2000, and RM-3000, as well as other early concept drawings of peripherals and very early (1981) concepts of what would become the ALC/CC-40. 1981_ALC_Concept_Drawings.pdf 2 Quote Link to comment Share on other sites More sharing options...
+acadiel Posted December 12, 2020 Author Share Posted December 12, 2020 This is first of five revisions of the cartridge for the CC-40. This is the "Type II" - rev from 3/23/83 CC-40-module-3-23-83-schematic.pdf 2 Quote Link to comment Share on other sites More sharing options...
+acadiel Posted December 13, 2020 Author Share Posted December 13, 2020 The second of five revisions of the cartridge for the CC-40. This is the "Type II" - rev from 5/3/83 CC-40-module-5-3-83-schematic.pdf @brain - Hopefully these will be confirmation of the exact dimensions of the CC-40 carts! 3 Quote Link to comment Share on other sites More sharing options...
+acadiel Posted December 13, 2020 Author Share Posted December 13, 2020 This is not one of the 5 module board revisions - I believe this is a header cartridge, meant to crimp a ribbon cable on (probably for the EPROM/module simulator). 1983_CC40-Header-Cart-09-1983.pdf 2 Quote Link to comment Share on other sites More sharing options...
+acadiel Posted December 14, 2020 Author Share Posted December 14, 2020 A little bit of diversion here. I think this is the final schematic set and block diagram for the CC-40. These three pages were the latest dates that were stapled together. Someone, please validate. Thanks! Sorry it's taking longer to come out with these... these three pages took me an hour and a half to clean up. If someone wants to take some raw scans and do the same page whitening/cleaning up - let me know, and I can throw them over to you for processing. Also, there's a LOT of very light lines that need to be fixed on this one. I have the raw ABBYY FineScanner 15 files if anyone wants them to try and fix the schematic (or can draw on the PDF itself to fix it.) 1983_CC-40-final_schematics_and_block_diagram.pdf 3 Quote Link to comment Share on other sites More sharing options...

+acadiel Posted December 31, 2020 Author Share Posted December 31, 2020 Now, this is really cool (and the first time we've seen this type of code) - another TI response to a customer, this time with several assembly routines that handle Hexbus communication. This source is 7000 assembly, and even has an example cartridge header, Hexbus operations in assembly, you name it. 1983-CC-40-OTRAN_Assembly_Sources.pdf 5 Quote Link to comment Share on other sites More sharing options...
+acadiel Posted December 31, 2020 Author Share Posted December 31, 2020 This is cleaned up as best as I could - it looks like a 2nd gen copy. The December 1981 document and schematic are the Preliminary Specifications for the ALC I/O Bus controller (later known as the Hexbus interface). 1981_ALC-IObus_Controller-Prelim_Specs.pdf 5 Quote Link to comment Share on other sites More sharing options...
+acadiel Posted December 31, 2020 Author Share Posted December 31, 2020 This August 1981 document is the gate array timing specifications for the "Lone Star" - which was the code name for the ALC (then CC-40). 1981-Lonestar-Gate_Array_Timing_Specifications.pdf 5 Quote Link to comment Share on other sites More sharing options...
+acadiel Posted December 31, 2020 Author Share Posted December 31, 2020 Here are the functional specifications for the same gate array - this is a 1981 draft, and there might have been changes. 1981-Lonestar-Gate-Array_Functional_Specification.pdf 5 Quote Link to comment Share on other sites More sharing options...
+acadiel Posted December 31, 2020 Author Share Posted December 31, 2020 This seems to be some kind of markup format - May 1983 Intelligent Bus Controller Data Manual (Hexbus). The first place was very badly damaged toward the bottom, so I tried to reconstruct what I could. There's some marking at the bottom to the left of the I/O Bus Buffer (very left bottom) that are damaged. 1982-Intelligent_Bus_Controller_Data_Manual.pdf 5 Quote Link to comment Share on other sites More sharing options...
+acadiel Posted December 31, 2020 Author Share Posted December 31, 2020 This is a 1983 version (v3.2) of the Intelligent Peripheral Bus (Hexbus) Structure - Timing/Protocol/Specifications. I believe it's an earlier iteration of what I've seen floating around. 1983_Intelligent_Peripheral_Bus_Structure_Timing_Protocol_Spec_v3.2.pdf 5 Quote Link to comment Share on other sites More sharing options...
+acadiel Posted December 31, 2020 Author Share Posted December 31, 2020 Last one for a bit. The 1983 CC-40 Editor Assembler manual. This is a nice copy. Next one will be the CC-40+ Manual. 1983-CC40-Editor-Assembler_Manual.pdf 4 Quote Link to comment Share on other sites More sharing options...
