Re: Got my RAM Drive kit today

I finally got around to finishing the ramdrive. I followed the instructions on how to do the fw upgrade and it worked like a charm from the start. Next thing will be to play around with the assembler and try to do something fun.

Re: expansion board and 6532 board now available

On page 28 of the users manual you can see that the second, optional, RIOT is mapped to $1700-$173F. Looking at the 6532 datasheet I assume that the register layout for the ports are as follows. I have not seen the schematic yet so if I'm wrong please correct me. DRA $1700 DDRA $1701 DRB $1702 DDRB ...

Re: My micro-kim goes color graphics

Thanks Vince, I have always wanted (for some obscure reason) to make a graphics board of my own with the MC6847 and MC1372. Probably because my first real computer (not counting the ZX80) was an Acorn Atom, which used the same VDU, but without the color modulator. So I had to endure bw for several y...

The weirdest thing happened yesterday.....

I've had my uKim up and running for a week and yesterday I decided to work on my graphics card again. After powering down and making some changes to my card I reinstalled it, powered my unit up, pressed reset and...... nothing happened. I tried resetting the machine numerous times and it would occas...

Re: My micro-kim goes color graphics

I finally got the time to try out the new transistors (2N4403 and 2N4401) as suggested in the Motorola Datasheet. And although the image isn't fantastic it certainly got a lot better. Now, what I really wonder is what the Motorola guys were thinking when selecting the palette :roll: The colors are r...

Re: My micro-kim goes color graphics

Forget that last part, S-Video still requires a modulated chroma signal, not the pure color video signal as in component video. I'm going to try replacing the generic BC547/BC557 that I am currently using, to the suggested 2N4401 and 2N4403 which I understand have lower capacitance and would more su...

Re: My micro-kim goes color graphics

I have attached the schematic here as well for anyone interested, the forum did not accept pdf files for some reason so I had to make it a zip file before uploading it. I am a bit suspicious towards the MC1372 device. It seem impossible to get a good picture on my NTSC LCD-tv. The colors bleed heavi...

My micro-kim goes color graphics

I built micro-kim some years ago when he was pretty new and ever since he has been sitting on my shelf looking pretty sad, poor thing :cry: So I decided to cheer my u-kim up and get him a gift. I sat down one weekend and designed a simple color graphics card. Based on the MC6847 and a MC1372 chip it...

Got my kit yesterday....

and built it during the commercial brakes in the TV-show Medium. An excellent spent hour of entertainment and fun.

Worked right of and is now a great complement to my Altair.

Thank you Vince for another great kit.

Looks superb :D

I certainly will be wanting one when they are available, or maybe two. Will give my really old S-100 systems a real boost.

I thought about doing it on a 48-pin DIP sized module but needed the extra pins to route the high FLASH address pins out from the module. Any banking needs to be implemented outside the module. But who knows what will happen :)

My latest 65C02 creation

I keep myself busy with numerous projects and found myself wanting a simple CPU module that I could use for different applications. And voila, I came up with this. http://www.allthings6502.com/images/images/Wombat_mounted.JPG It's equipped with 512Mbyte FLASH, 32KByte SRAM, Reset device and an oscil...

Dasm (http://sourceforge.net/projects/dasm-dillon) is another great assembler. I use it for all my 6502 assembler projects. If you want a more advanced environment with link possibilities you can always have a look at www.cc65.org
