Where was it coming from? Just white-noise gibberish because I didn't have a signal source connected?. Sorry, I assumed that you were hearing dahs & dits on your monitor when pressing keys for transmit mode rather than white noise. Most RTTY interfaces worked in this manner, in part to help nov...

Great find for your Vic-20!!! You seem to be getting all the neat toys lately. How much did you pay for it? The mystery code you heard was morse code. I have several plans for RTTY interfaces from old magazines. Many of the early adopters of computers were amateur radio operators as well and built t...

You're also in Toronto, right? You're welcome to take a look at the insides of mine...maybe in return for some help with EPROMs etc... 8) Edit: Someone else already took their apart and posted a pic here: http://www.mainbyte.com/vic20/display_manager.jpg[/quote] Yes, I'm in GTA.

Does your documentation include any info on what chips are used or theory of its operation?

Good idea Jim!

Why two crystals for 6551?

Try Craig Bruce's word processor - Zed for C128.

It will use 64kb VDC memory.

Does anyone have a copy of - Crt Controller Handbook by Gerry Kane?

I'm looking for some detailed info on 6545 (yes, I already have datasheets and Synerk Application note).

I'm looking to use the 6545 for video display as part of my 6502SBC project.

Thanks!

Wow!

I don't know too many Vic-20 fans who would be willing to part with $2K for their hobby.

So far noone with a PET/CBM of either model? Of course PCs only would count if they were made by or under the Commodore brand. Actually one of the C64/Amiga mags I have once reviewed the latest fan-less PC-1 (or PC-10 ?) which was an odd article to understand if you didn't know about PC and MS-DOS ...

I have:

10 -- Vic-20
3 -- C64 (brown box)
1 -- C64 (flat style)
4 -- C128
4 -- 1571
3 -- 1541


I can count over 50 computers + over 25 monitors in my basement / computer room. It is getting more difficult to find space for new stuff.

Do I have a collecting problem???
