USE CURSOR KEYS TO SCROLL TEXT. USE CURSOR KEYS TO SCROLL TEXT. To: 999 (all members) From: K5B (David J.MacGraw) Subject: 512 and DOS+ Part 1 8BS is now distributing and extending the BBCPD 512 collection of DOS+ based software. This remarkable system uses an Intel/AMD 80186 microprocessor, but runs all I/O activity in the BBC host via the Tube. It is capable of running many of the older DOS programs but not those needing better than CGA displays or mega-bytes of memory. The occasional article on 512 and DOS+ topics is, hopefully, not out of place in this magazine and any contributions from other 512 users would, I'm sure, be welcome. Questions, tips, problems and solutions, enhancements, software reviews/compatibility and so on would all be of benefit to other users. I am by no means an expert on the 512 (or the BBC for that matter!) and use it mainly at home in a Master 128 with a 20M Hard Disc (\ ADFS, \ DOS+) and a twin 5{" floppy disc drive. I used it initially as a 'hands-on' introduction to the world of PC's but it is proving to be a valuable aid in understanding the inner workings of the M128 as well! The following are probably essential for any 512 user: BOOKS: 512 User Guide c/w disc by Chris Snee. 512 Technical Guide c/w disc by Robin Burton. (Both are available for hire from Richard Chamberlain's Book Loan offer.) HARDWARE: 1 meg.memory expansion PCB Solidisk and Essential Software once produced and fitted these. (If there is sufficient interest, a new version could be produced. Watch this space for details.) SOFTWARE: DOS+ v2.1 and supporting s/w as supplied by Acorn. PCCE, Mouse Driver and 512 Technical Information by David Harper. (Available from 8BS: disc 512-3-1.) OSCLI, RAMDISC and PRTSCRN utilities by Essential Software. A hex.File Viewer/Editor A text File Viewer/Editor A file compression utility Many of the other programs produced by Essential Software put the 512's twin- processor system to good use, MEMOPAD being perhaps the best example. This uses the host's SWRAM as an instantly accessible notepad (for 'in-program' note-taking, memos, instructions etc.) with printing and filing facilities. CPFS+ is another winner. This uses the 512 as a large, very fast ramdisc (BBC) filing system and/or printer buffer. TIP: The !Boot file given on page 175 of Chris Snee's User Guide doesn't work if CPFS(+) is fitted. Use this version instead: (supplied by Robin Burton) *BASIC *CO.TUBE ?&FEE0=&A0:?&FEE0=&20 ?&FE4E=&7F:CALL!-4 On my setup, which uses Pineapple's ADU ADFS management rom, I move the cursor block in the *MENU screen to the 'DOS' directory (containing the above !Boot file) and press Shift/Copy/G. This then automatically enters the directory and EXEC's the file, which resets the 512, simulates a Hard Break, installs and starts up DOS+. This concludes my first 512 article. I hope to include various tips etc. in future contributions and would welcome any comments or suggestions as to the content of this occasional series from all other 512 users. ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
