-
- CBI * Coral Basic Interpreter version 7.0 by Carlo Delhez,
- Terminal Software, 1987
- * extension of ZX81 basic and editor, machine coded
- * type POKE 16388,8 \ POKE 16389,107 \ NEW before loading
- * when having started CBI with RAND USR 27400, useful commands
- to type are ERR MSGS ON \ NOSTALGIC OFF
- * pseudo screen editor, no tokens but full typing, space
- insensitive commandline interpreter
- * many new commands available, e.g. for structured loops,
- procedures, renumbering, indentation, graphics, debugging
- and machine code utilities; manual available on request
- * user-friendly syntax check returns cursor near or at error
- * exit by typing EXIT or NEW
-
- CBI-DEMO * Coral Basic Interpreter Demo by Carlo Delhez, 1987
- * demonstrates some features of CBI, in Basic and machine code
- * load program only when CBI is active (otherwise error C)
- * demo is mainly intended for studying the new features of
- CBI, not as a serious toolbox
-
- CBI-KEY * Coral Basic Interpreter Key Repeat by Carlo Delhez, June 1990
- * alters key repetition of CBI, in Basic
- * load program only when CBI is active (otherwise warning)
- * the normal keyrepeat of CBI may not function well on fast
- computers or on computers with dirty key switches; the code
- of CBI is changed for more reliable repetition
- * line 130 holds the start address of the CBI code, line 140
- represents a delay factor (try 15 first, then change)
- * with altered key-repeat you cannot type quicker than the
- POKEd delay factor!
-
- CBI-REL * Coral Basic Interpreter Relocator by Carlo Delhez, undated
- * adapts code of CBI so that it can be moved to another address
- * first load CBI and then this relocator (CBI inactive!)
- * the relocated version can be SAVEd as a code file or be
- moved to the required address immediately; you must do this
- yourself
-
- CLCKFREQ * Clockfrequency by Carlo Delhez, October 1991
- * benchmark program to determine effective processor speed
- * does some simple printing and plotting and counts the number
- of frames needed; this is compared to the original ZX81;
- the result gives a rather good indication of emulator speed
- * requires Frames to be emulated (OK on XTender & XTricator)
-
- GRAFFITY * ZX81 Graffity 1989 by Carlo Delhez, February 1989
- * painter-like game, machine coded
- * try to paint all the city walls but watch out for
- the cleaners, tourists, police and super-brush
- * 10 screens, 10 speed levels, large sprites, fast action
- * steering: A & D : left & right
- 9 & K : up & down
- * steering also user-definable (`change keys')
- * exit at main menu by pressing `Q'
-
- RED-ANTS * Red Ants by Carlo Delhez, August 1984
- * maze game, machine coded
- * walk through the giant ants nest, eating their eggs and
- meanwhile looking out not to get stung by an ant
- * vast maze, special steady-player screen scrolling
- * steering: instructed
- * exit during title page by Break
-
- SIMDOS2 * SIMDOS/2 version 0.04 by Carlo Delhez, June 1992
- * RAMdisk driver, machine coded
- * after loading, the program is copied to the 8-16k section,
- starting at address 14000; commands are issued as follows:
- PRINT USR 14000;"<commands>"
- * available commands are (separate them by ';')
-
- DEL:<name>.<type>: delete file
- DIR: show directory
- FORMAT:<addr>:<len>: format disk & show directory
- LB:<name>: load basic program (.B)
- LC:<name>:<addr>: load code file (.C)
- LL:<name>: merge basic lines (.L)
- LP:<name>: load complete program (.P)
- LS:<name>: load display file (.S)
- RUN:<name>: load & run program (.P)
- SHOW: show help screen
- SB:<name>: save basic program (.B)
- SC:<name>:<addr>:<len>: save code block (.C)
- SL:<name>:<1st>:<last>: save basic lines (.L)
- SP:<name>: save complete program (.P)
- SS:<name>: save screen (.S)
-
- * the commands SBO, SCO, SLO, SPO, SSO are the same as the
- ones without the 'O' but they will delete a file of the
- given name first (when it exists) and then save the data
-
- * examples: "FORMAT:32768:16384:" : format 16k disk at 32k
- "SS:TEST:;DIR:" : save screen, show directory
- "SC:ROM:0:8192:" : save ROM code
- "DEL:TEST.S:" : delete screen file
-
- * error messages: E : lines merged
- H : file already exists
- I : linenumber does not exist
- J : syntax error
- K : file not found
- L : format error
- M : out of memory (disk full)
-
- * type NEW after loading to clear ZX81 memory; the RAMdisk
- is preformatted for 32760 bytes at address 32768
-
- YAHTZEE * Yahtzee by Carlo Delhez, September 1983
- * dice game, Basic
- * fill your Yahtzee sheet by trying to throw the right
- combinations of dice; rules of Yahtzee not included
- * up to 20 players, Dutch text, sorted scores
- * exit any time using Break
-
- ZX81TIME * ZX81timer by Carlo Delhez, November 1991
- * digital clock, machine coded
- * a sizable digital clock; accuracy of the clock depends
- on the accuracy of Frames emulation; the clock should `flash'
- at 1 Hz and should be as accurate as, say, 1 second/hour
- * source code of machine code included in line 2; can be seen
- with editor of ZX Assembler
- * initial time requested by program
- * exit while clock is running by pressing Break
-
- ZXASSEM2 * ZX-Assembler-2, revised version by Carlo Delhez, 1991
- * rewritten version of this excellent Assembler, machine coded
- * this version resides in line 0; the source code is stored
- in line 2, the object code in line 1
- * Type LET OC=USR 16516 then assemble your source and quit;
- on return, OC holds the start address of the object code
- * ORG directive is added; use COPY option after assembly
- * use ORG +16516 and remove line 0 to get proper `1 REM' code
- * more extensive manual available on request
- * most options can be quitted by pressing Q or Shift-Q
- * exit assembler by pressing Q twice at main prompt
