7. Lage 9 51 18 8 0 ibikan N 1 31 REN 1 To me the C65 has the sense of being what the creators of the C128 might have liked to have done given enough time It also contains obvious lessons learned from the C128 principally that all advanced features can be accessed from C64 mode In fact the C65 boots in C64 mode first and a modified C64 mode kernel decides whether to jump to C65 mode In terms of specification the C65 is like a cross between the C64 and Amiga 600 It has stereo SIDs the newer 8581 type The units shipped with 128KB of RAM and an Amiga like trapdoor slot that theoretically take another 8MB of RAM but not without some rather scary memory banking tricks involving two nested levels of memory banking The trapdoor slot mapped 512KB ata time into the 1MB address space of the 4510 processor and required the memo ry expansion to include a special register to select which 512KB bank was required The byzantine logic to make use of this was built into the DMAgic DMA controller or at least was sup posed to be I don t know if anyone knows whether it was actually all implemented in the experimental units The DMA unit is however handy for memory fills and copies and is heavily used in C65 mode for screen clearing screen scrolling Commodore Free Magazine CORRU HI K be and accessing BASIC variable and pro gram storage The C65 has an internal 3 5

13. in the C65GS s VIC IV For me the important thing is that it is still purely 8 bit and feels like an 8 bit computer So all IO is direct mapped POKE is a skeleton key that lets you do anything and booting is mostly a euphemism for letting the ROM clear the screen and say READY Page 30 already getting very hard to source FP GA replacement of ICs is a good backup plan However I have been doing a bit of digging around and if we can raise the necessary funds there is a chip fab in a Canadian University that uses the right kind of process that would allow us to recreate real SID chips real VIC II chips and all the other custom chips As a University fab the costs are sur prisingly low especially if it is connect ed in and becomes part of their VLSI teaching If this can succeed then it will be the golden standard for preserv ing old computers but as I say FPGAs are a good backup plan and have the advantage that we have them now Q talking of cloning is that how you see the designs in FPGA Is it clon ing of the machine Well I hope to provide as close to 100 compatibility for C64 mode as I can This might mean having a 4510 and 6510 CPU and a VIC IV and a VIC II in the design to achieve this However I don t intend to exactly clone the C65 It was never finished and so I am re imagining what it could have been and giving it some capability and perform ance boosts along the way so that the end resul

16. row This means that clean raster splits are easy to write but it probably means that some advanced tricks like FLI and DMA delay based effects may not work on the VIC III It also has a 256 colour palette with 12 bit colour 4 096 possible colours like the Amiga 500 32 colours can be used in text and nor mal bitmap modes through the use of an extra bold flag bit in the colour RAM which is not 8 bit wide and is really just 2KB of the 128KB internal RAM unlike on the C64 where it is a Separate 1KB x 4 bit RAM The palette can be changed at anytime so it is pos sible to have many more than 32 col ours visible in a single frame To have more than 32 colours it is necessary to use new bit planar modes like on the Amiga Unfortunately with only 128KB of RAM this is really memory inefficient and with an 8 bit CPU at 3 5MHz really slow The focus on pla nar graphics even though allowing 8 bit planes and hence 256 colour graph ics is in my view a Serious design mis take Having a super character mode with 256 colour characters and allow ing more than 256 characters is more memory efficient for games where there is a lot of repeated graphics and also much faster to manipulate the dis play More on that when 1 talk about my C65GS design Q I often felt that Commodore missed out by not manufacturing apart from a few prototypes the Commodore 65 I know I would have bought one Commodore Free Magazine If Com

72. t while very C65 like will be a unique machine and I think a very fun machine That s really the goal that this be a machine that is similar enough to be nostalgic and give an au thentic experience of a real C65 but with some niceties like SD storage in stead of actual floppy disks and extras that can be accessed like extra RAM faster CPU ethernet more colours higher resolutions and so on if desired But when it turns on you will be think ing wow I get to play with a C65 Q Someone once said to me the holy grail of cloning or implementa tions would be to create a SCPU in FPGA I see one of your goals is to provide a machine faster than the SCPU so will SCPU compatibility be programmed into the design Well that is the holy grail for some at the moment and I am sure will contin ue to be for a number of people How ever the C65GS is already faster than the SCPU especially for video intensive tasks The only real advantage of the SCPU right now is that GEOS works on it It won t be hard to add C65GS sup port to GEOS and once that is done there will be only a very few SCPU spe cific programmes that people will miss out on So my personal view is that SCPU compatibility will not be high on most people s agenda if they had a C65GS Talking about GEOS I am actually very looking forward to seeing it ported to the C65GS Pretty much all the func tionality required is already there for it to work
73. t has been used in many applica tions and quite prominently by most of the major turbo uti lity cartridges The Buddy assembler and accompanying text editor is another good example What is PRIMM or print immediate In short it is a function which allows the 65x programmer to print an inline 0 terminated petscii text string That is placing the string characters and optionally screen location coordinates directly after the call to print our string Normally we tend to place our code in one loca tion and our data in another separate space This can make JSR PRIMM text Hello World 0 more code follows RTS Instead of returning to execute the next instruction PRIMM instead does some parsing to retrieve and print the in line text string Once PRIMM encounters the zero byte 0 termi nator it returns to the code stream This is really very straight forward but it takes a moderate understanding of both the stack and the program counter Okay let s take a first look at the C 128 version on the left and our modified version to the right Commodore Free Magazine for cleaner more understandable code but other than for aesthetics or reasons related to personal preference there is really no rule which prevents us from placing code with and around data or from printing an in line string The C 64 does not have a function for printing in line strings but we can borrow from big brother C 128 So let s see ho

77. ts what would you have done differently given the limita tions of the day Ok so If we assume we had to work with the technology of 1985 but had plenty of time and money then I would have used the fastest 6502 compatible CPU of the time probably 8MHz or 16MHz and made a new VIC II that did 40 and 80 column output to either a composite or RGBI video output Also I would have made C128 mode re acces sible via secret knock register like on the C65 The memory management would also be a lot different Q Finally I would like to thank you for your time and do you have a com ment you would like to add You re welcome The only comment I have is to emphasise that this is an Open source project and so other peo ple are more than welcome to contrib ute with VHDL programming testing documentation or any other activity that interests them My hope is that others can derive some fun from what I have begun to create Paul av pij C4 74I Plus Edition 29310 www commodorefree com COMMODORE FREE INTERVIEW WITH MELON64 SYSADMIN Some people were worried Lemon64 would be no more after attempting for days to access the forum and with no success then suddenly another forum formed up called Melon64 Soon enough though the Lemon64 forum was back but does this mean we have to choose our forum or can both live in harmony WE asked Melons sysadmin to shed some light on the new forum Although I
