Re: 4040 dual floppy
What is it with UK sellers? Had another one cancelling this order with the explanation: "Hi, if you are from outise of you UK i wont be able to send it to you. There is a lot of restricions to send electronics that are so old :( i am not sure if thats not the reason." That is after giving ...

Re: 4040 dual floppy
IEEE on the user port? IEEE requires 13 I/O lines, 8 for data, 5 for control signals. The top of the user port gives us 10 (PB0-8 + CB1 & CB2), there's other lines on the bottom (joystick, tape) that could be used for the others. Well if it could be done without the 232, that would be better, b...

Re: 4040 dual floppy
My immediate problem with a IEEE solution would be that it occupies the expansion port which I need for other things. So a 232 solution would enable me to have the expansion port free. That's easiest solved with multislot expansion board. Granted they aren't easy to find these days. It should be st...

Very nice sprites! The isometric reminds me of Spy vs spy.

Re: 4040 dual floppy
I'd drop a line to dragos and see if there are any spare replica VIC-1112s left https://www.kickstarter.com/projects/1203958506/vic-20-ieee-interface If you go any other route you will need to transfer IEEE commands to the drive, that will mean writing your own LISTEN, TALK etc routines and then pa...

4040 dual floppy
I just bought a 4040 and the obvious option is a Vic-1112 IEEE-488 cart. Schematics and ROM code are even available to build one. An alternative is to buy a RS-232 to GPIB adapter, but that may require some not-so-obvious way to send commands to the drive. Has anyone tried that here and if so, what ...

Re: WIP(?): A proposal for a VIC-20 with 60K RAM
@Mike Obviously since your project is well structured, coherent and more than likely perfectly feasible, we're bound to see kakemoms exhibit strictly no interest in it... I suggested the multiplexed address lines and fake address solution as a favor to him. I have absolutely no interest in a projec...

Re: Term
Any modem that did support this speed at the user port? Most commodore modems seems to have been up to 1200baud unless you went for a RS-232 interface with a modem through that.plbyrd wrote:Anyone have VIC term that supports color PETSCII at 2400 on the Userport?

Ok, great to clear that up. You answer this questions straight, without trying to ridicule the person asking. I appreciate that.groepaz wrote:its just that ALL drive roms are based on the old drive roms from IEEE488 era - no more no less. it doesnt really support IEEE488

Re: Would anyone like to complete Mighty Term?
Those screenshots look fun and make me want to use my VIC-20 to connect to some of the remaining BBS's. Not trying to divert the thread, but are there any wireless versions of ethernet modems that work with the VIC-20? Like this but wireless (my VIC-20 is in another room nowhere near my internet mo...

Re: Tricking the 6502 addressing to access 54KBytes of SRAM
This is claiming to be a 64k ram expansion for the VIC20 ? Here Interesting! I didn't know that a 64K expansion was made in the heydays of the Vic. Those guys were forward thinking! My other project here has a 128K or 256K paged expansion. But this tread is about non-paged expansion. It means you h...

Re: Cartridge based kernel
Kakemoms deliberately ignores some fundamental principles of digital electronics. It is not, and never was, a good idea to let two digital outputs play tug-of-war. However, as long as he only fries his own VIC-20 with those experiments, that's not my problem. Hey... that's exactly what I said in th...

Re: VIC ultra minimum system
You could try to use a WDC 65C134 which has ROM and a few bytes of RAM built-in. Not sure if its enough to get the 6561 to do something, but it has a serial bus built-in so you may be able to control it from a PC or alike. I was actually planning to use the 65C134 myself, but have started with the 6...
