[CoCo 2 + CoCo SDC problem]

Finally found a cheap solution and upgraded my CoCo2 to 64k (2x 4464) and Extended Basic on an ordinary 27128 eprom (Extended Basic V1.1 - 0h -1FFFh & Color Basic V1.3 - 2000h - 3FFFh).

[CoCo 2 + CoCo SDC problem]

As i mentioned before ... I don't have any problems with the Dragon + CoCoSDC. Had one regarding the CoCo 2, but the reason was the missing ext. Basic ROM in my CoCo.

Thanks for the funny joke.

 

Still searching ... EU only.

[CoCo 2 + CoCo SDC problem]

Well ...

 

No chance to contact Ed here, 'cause he never replied my PM (he wasn't here since month). I'm not at crappy Facebook and there is no contact adress on his homepage ... so this forum would be my only chance ...

[CoCo 2 + CoCo SDC problem]

Hi,

 

i used the CoCo SDC interface for my Dragons so far and it worked very well.

 

I've a CoCo 2 as well, so i tried to run the interface with this one.

 

What i did:

 

- changed the Dragon DIP switch to off (all switched are "down" now) and removed the jumper from the DRQ pins

- plugged the interface in and ...

 

... i only got the normal CoCo 2 basic screen.

 

After that i put the jumper to AUTO and i only got a white screen and nothing happens.

 

Well, i think, that i should get at least the SDC boot screen ,,,

 

Who could help?

 

Thanks.

[What did you buy today?.........]

Received a Sharp MZ-800 (with a quick disk drive included, so it is a 821 which had the tape drive replaced) with a amber monochrome monitor for my collection.

 

Great machine ... i tried some wavs to check it.

I'm restoring an Acorn A3000 at the moment and i hope i'll succeed.

[What did you buy today?.........]

Bought an Archie A3000 with a leaked battery. Will repair this one when he arrived.

 

[What did you buy today?.........]

Bought a CoCoSDC from a good guy, so i don't have to bother with the very strange and unfair selling behaviour of some other people.

 

 

A Dragon32.

There should be a list ... all other procedures are not fair..

 

Some people are NOT using such crap a like faceb. and other similar things ... and want a CoCo2SD since month.

 

I still want one, but i don't wanna sell my soul for this. It should be fair ... that's all i want.

[color computer 2 composite mods for sale]

Well ... and there are no other AVAILABLE mass storage possibilities for the CoCo2?

[Defective Oric 1 and Atmos ... need help for a repair ...]

Yes, i know ... i'll transfer the issue 3 board into the Atmos case (and put the V1.1 in the rom socket), so i've time to repair the issue 4 board. I get an 6522 in the next days, so i hope, that this one caused the error.

[Defective Oric 1 and Atmos ... need help for a repair ...]

Atmos:

I desoldered the old cpu and put a socket in. Tried three different cpus and the Atmos still has the same issue (the pattern i showed in the first post). I checked the socket again and again, but that changed nothing. All cpus worked with the Oric 1, so there must be an other problem. I piggybacked all RAMs ... nothing. Crap.

[Defective Oric 1 and Atmos ... need help for a repair ...]

Ok, bought some UM6502 in Ireland ... i desoldered the old cpu of the Oric 1 and soldered a socket (my first socket so far) ... put the first cpu in ...



... AND ...

 

Tried some keys and they works so far. I'll test the Oric 1 with a test ROM, so i hope, that the cpu was the only bad component ...
