+FarmerPotato Posted October 21, 2022 Share Posted October 21, 2022 From Susan Bailey’s comments in the source, the TI Writer Formatter was ported from Pascal. She leaves in some of the Pascal statements as documentation of the logic behind assembly code. From evidence in many TI documents, the software to format them would be familiar to us. For example, the Hexbus Specification has some typos that reveal “ .” commands by the space in front. Many documents have ASCII line drawings of data structures or system hierarchies with looping arrows. For example, the PAB format, 4A memory maps, etc. I’ve been reproducing these diagrams with an online ASCII box drawing tool. (From the HexBus specification, and the Speech Education Module docs.) I’d like to know what the original formatter was like. If there were box and line drawings commands. Maybe another tool in the chain, like Unix pic? Is a text formatter documented in any of the DX10 or DNOS manuals? Is there a pointer to a lost manual that it would be in? It would be fascinating to connect with TI-Writer’s “big brother” or mother! I don’t think the set of formatter commands came out of nowhere (though it’s similar to Unix runoff and nroff and even WordStar had dot-commands.) From a 1979 ACM article about TI’s internal network, many terminals were installed for word processing, connected to various 990 systems. 3 Quote Link to comment Share on other sites More sharing options...
