new Mega 65 prototype pcb - connectors

append delete adtbm


i have a question, i have just seen the pictures of the prototype Mega65 board.
i was not able to see any connectors for the SID(s).
Are they still in the planning ?
That there is no Tapeport i knew already from recent podcasts, what is with the Userport ?

Can you maybe post a board description, what connectors are there ?
(Of course, seriell, joystick, etc., is obvious)

Thanks in advance and i just wanted to say, the board looks great. (Even if it looks a class harder to solder at home, compared to the previous widget board (and that one was allready challenging)).

The final set of connectors has not yet been settled. What there is currently, is:

* C65 keyboard
* IDC header with keyboard pins (will probably be changed to a C64-compatible keyboard connector)
* 24-bit VGA out
* 24-bit HDMI out
* 34-pin standard floppy drive connector
* C64-compatible cartridge/expansion port
* 3x PMOD connectors (common on FPGA development boards)
* 50-pin IDC expansion connector
* C= serial floppy drive port
* Connector for USB serial debug
* Power switch
* Reset switch
* Joystick ports

As I say, the final list of ports may end up somewhat different. What is likely for now, is that if you want a tape or user port, these will probably connect via a PMOD or the 50-pin expansion connector. The lack of these physically large ports all comes down to cost. The bigger the PCBs, the more expensive.

We do hope to add sockets for SIDs. Worse-case scenario, they will be usable from a cartridge.

Thanks for the answer Paul !
I like the decision, to maybe make the Tape/Userport optional attachable via PMOD, or 50-pin IDC.

If i may ask one more question: What will be the operational Voltage ?
Since the SID operates with +5VDC and +9VDC/12VDC (8580/6581)
and the FPGA normally runs on 3.3VDC, will the Voltages be generated onboard, will you be using transceivers again (Like on the widget board)?
What are your plans regarding this ?

paul......CAN the sid be on cartridge????
