JohnPCAE Posted January 2 Share Posted January 2 I have 5 more ACC boards, and I've started building the first of them (that's the one on the top). I don't have all of the chips I need to complete it yet, but over time I plan to have a total of 9 units (one is for me). I don't know how long it will take, we'll see. When they're completed, maybe I'll build another 5 (boards come in batches of 5). Who knows? It's only a shame that we don't have something like PhillyClassic anymore where I could drive up and show one off (and maybe hand some out!) 6 Quote Link to comment Share on other sites More sharing options...

mdoerty Posted January 3 Share Posted January 3 What can these be used for -- other than for specialized games? Quote Link to comment Share on other sites More sharing options...
JohnPCAE Posted January 3 Author Share Posted January 3 (edited) They provide several main features: - Overlay video (extra sprites, 40x24 and 80x24 text, bitmap graphics modes) - 64k-words of bankswitched RAM that's shared between video and the coprocessor - Emulated coprocessor with a much-extended CP-1600 instruction set - 8-bit parallel port I chose a parallel port because it's easy to implement and easy to program. You presumably could use it to interface to lots of things with the right software. Edited January 3 by JohnPCAE 1 Quote Link to comment Share on other sites More sharing options...
JohnPCAE Posted January 5 Author Share Posted January 5 I hasten to point out that everything needed to build one of these is available (see the attached ZIP). I'm guessing they cost $100 to $150 to make. The hardest parts to acquire are the EDAC cartridge connector and the power supply: those can take weeks or even months to acquire if they aren't in stock. I've been getting the purple parallel port jacks by buying cheap PCI parallel port cards and desoldering the connector, but you can get new ones (in black) pretty easily. I've tried finding anyone selling purple connectors to no avail. Another word of caution relates to the 7202 FIFO chip. 25ns or less will do, but some sites like Mouser demand a huge minimum order. I've had better luck at Digi-Key for getting those. Advanced Console Component 20221217.zip 1 Quote Link to comment Share on other sites More sharing options...
JohnPCAE Posted January 13 Author Share Posted January 13 Updated the hardware BOM. The 08 (AND) and 04 (inverter) chips need to be of a specific type for clear video. Advanced Console Component 20240113.zip 2 Quote Link to comment Share on other sites More sharing options...
pacmannumber9 Posted March 16 Share Posted March 16 I hope the ACC becomes finished product people can attach to Intellivision. I like the idea of using real Intellivision hardware and having more sprites. 1 Quote Link to comment Share on other sites More sharing options...
