I think you're right *g*

Hy!

I think it's a good idea to start such a project.
In my opinion, diskettes are still useful, but too old.
I suggest using a DATA-POD, described on the 6502.org

good luck!

Hi Folks!

Hope you can help me (again) attaching a cathode-ray-tube (TV Screen) to my SBC. It's been canibalised from an old GRUNDIG SYSTEM 5300 Oscilloscope and has a monochrome screen with approx. 3" diagonal size.

There are...
- 2 thick lines (red/blue), I think they're for power connection
- 5 ...

Thx, now I'll be able to connect the different busses.
But I got another problem with the 65c22 output pins labeled RS0 to RS3.
Due to the schematic, the RS-Pins should be connected to the Address Bus lines 0 to 15. But it doesn't seem logical to me that 4 output lines can be connected to 16 bus ...

Hy!

As You know from an earlier post I want to rebuild the 65c02-SBC.
But because I'm fairly new in electronics, I don't understand the Bus connectors. In the schematic file, there are fat blue lines labeled A[0...15] and D[0...15]. These seem to be the Data-/Address-Bus, I think. But how to ...

I'm going to rebuild the SBC-1 on Darryl's page, and I want to connect twenty 7-Segment to the parralel I/O. But how can I connect 140 LEDs to a 16-Bit I/O-Controller? Please help!
