Commodore Color Graphics Manipulation System Terminal
by Craig Smith (1985-1988), alwyz (2017-2020), Michael Steil (2022)
- based on 5.5 source by Craig Smith 01/1988.
- 2017-2021 mods by alwyz (see ccgmsterm2021 for final alwyz version)
- fixes and additions by Michael Steil, 2022
- 40 column color mode
- 80 column color mode 🔴
- PETSCII and ASCII/ANSI encoding
- Serial drivers (stable on NTSC and PAL 🔴)
- User Port (300-2400 baud)
- UP9600 (300-9600 baud)
- SwiftLink $DE00/$DF00/$D700/NMI (300-38400 baud)
- File transfer protocols:
- Punter, Multi-Punter
- XMODEM, XMODEM-CRC, XMODEM-1K 🔴
- Phone book with 30 entries and auto-dialer
- Configuration & phone book load/save (disk or EasyFlash)
- DOS command and directory
- Macros
- Screenshots
- Themes
- REU buffer (64 KB)
- RR-Net support
- WiC64 support
- YMODEM/ZMODEM/HMODEM protocols
- IDE64 compatibility
- Additional cartridges (e.g. Lt. Kernal)
- 100% support for hardware acceleration devices (SuperCPU etc). Certain conditions may affect file transfer handshake timing.
- #5: XMODEM (and possibly PUNTER) transmission may be broken for UP9600 devices
- #10: XMODEM/1K may fail for SwiftLink cartridges with a real 6551 chip
Build with make & ca65.
Regular build:
make
EasyFlash build:
EASYFLASH=1 make
The EasyFlash version gives you the option of loading/saving the phonebook to cart and removes Swiftlink.
In either case, the resulting file will be build/ccgmsterm.prg.
To run CCGMS in x64sc with SwiftLink at $DE00:
make runsw
x64sc with User Port:
make runup
x64sc VICE with UP9600 (receiving OK but sending broken as of VICE 3.6.2):
make runup9600
The x64sc command line has changed recently, so these need at least VICE 3.6.
This repository includes automated and manual tests. See Testing.
- Added support for a software 80 column screen mode
- F8 now cycles: 40c PETSCII -> 40c ASCII -> 80c PETSCII -> 80c ASCII
- All menus, transfers etc. temporarily switch back to 40 col screen. The 80 column contents will be preserved when temporarily switching.
- In 80 color ASCII mode, the characters ^_`{|}~ are available, matching ASCII (unlike 40 col ASCII).
- Fixed ASCII-PETSCII conversion of codes 0x60 and 0x7B
- Changed some wording to be clearer (imho):
- "Graphics" and "C/G" to "PETSCII"
- "Anscii" to "ASCII"
- "Author's Message" to "Instructions"
- Internal changes
- rewrote RS232 driver model
- cleaned up code memory layout
- Fixed timing for PAL in User Port and UP9600 drivers
- Implemented XMODEM-1K
- protocol XMODEM-1K forces 1K on upload
- any XMODEM protocol will accept 1K blocks on download
- XMODEM-CRC autodetect on upload
- protocols XMODEM-CRC/-1K will force CRC on download
- any XMODEM protocol will accept CRC on upload
- Punter stack and Unlisted dialer bugs have been eliminated
- Support in autodialer for Zimodem and related WiFi device firmware that prefer an ATD prefix to ATDT.
bo zimmermans firmware (and maybe others) take issue with atdt, and prefer using atd instead for bbsing (uploads/downloads issue). hopefully this is the only issue with firmware compatibility. willing to solve this issue on the software side, though i'd prefer firmware uses a better standard. but fuck it, it's 2020 and who gives a shit anymore about standards on an 8 bit computer from the 1980s? so i added an atd/atdt menu option
- doing some bugfixing. dial unlisted doesnt restore bottom of screen after dial. now it does. cosmetic fix.
- abort punter crashes stack pointer because i bypassed jump table and apparently that is neccessary so its back in the calls from dowmen and f3 routines.
- easyflash false positive with reu detect. since ef and reu cant work together, added provisions at startup to prevent easyflash mode from even looking for an reu
- did some tweaks to autodialer. try counter now works to 99, and dial unlisted had some weird issues with that so that has been sorted as well.
- found one bug in the bottom screen display routine which has probably been there since ccgms 2017, but its good now.
- merged easyflash version into this one. only added 2 blocks. easier for maintaining
- still have some room from $5000-$5100 for more code/routines if need be. And can always add more code at $5c00 before the end
- fixing some possible issues with multi-upload. crashes between files. enablexfer not getting turned back on at the right time?
- re-did cf1 multi-upload enable/disablexfer calls... seems good now
- found a bug on the original punter sourcecode that incorrectly references var "delay" as delay 1 on 0 off, but in truth it is 1 off 0 on, so ive set both to delay on now update... ahh fuck it, no matter what, add delays every chance we can.... i disabled every opportunity to bypass delay around pnt106.
- f3 disablexfer improvements
- multi-receive disablexfer imrovements / trying to prevent crashing on multidownloads (noted on up9600)
- added punter handshake delays from ultimate version back in. baudrates faster than 2400 are definitely having problems with handshakes so its back!
- added jsr call to rsopen to baudrate changer. see if that fixes some weirdness
- first public beta. rewrite of pretty much everything....
- file transfers finally incorporate flow control. they never did before.
- resetvectors removed.
- re-wrote and optimized all modem drivers.
- removed a bunch of spaghetti code of my own making...
