well i dont know about the telestrat - i better go read the mess sourcecode : :D

i cant see why it cant be mapped the same, but i'm not sure the bits would be similar because the usage would be different.

let me go look into it. :arrow:

i looked at the mmc2iec some more, the way to go is to ditch the iec code from the atmel & go simple async serial or 8bit parallel with clock & ack. then (get ready to screem) add a second via to the oric. this will give an extra 8bit port too - joystick? i even considered dma, but that would be a p...

the one with a 9way d is totally different in every way to the one with din plugs & maybe a scart. (space on the board for a scart but i'v never seen one fitted) if anybody gets a 1084 then go for the one with the 9way d on it - it's way superior to the others. it was also badged by philips as the c...

i'm not so sure, that "intensity" pin will have to be left alone and you need to join the sync pins together.

the intensity pin may not like being unconnected.
if it almost works you could link the intensity pin to ground or 5v and see what happens.

the wrong way wil give a dark picture.

yea, if i can remember that far back i think loriciels was big on using unlisted opcodes!
not that it stopped me breaking there dodgy loader that abused the stack space.

dealing with overlay is easy, but most people would scream at my methods :) i'd replace the 16k rom with a 32k one, then use a gal to gate the upper address-line based on the address-bus and a signal from somewhere. i could have any combination of 1k,2k,4k,8k + whatever ram is left after in the 16k ...

that's an interesting link - bookmarked :) now as for the tape-sim, it handles any reasonable baudrate, the guy designed it from the begining to handle fastloaders & custom formats. and i just found this: http://www.ktverkko.fi/~msmakela/8bit/c2n-oric/index.en.html 8) as for the main thing - found t...

interest - good. a few things i should point out - i'm looking at things with an open mind with regard to working in the oric - end goal would be an sdcard system *internal* to the oric. but first - that digital tapedeck. it records & plays samples. it will work on the oric because it isnt system/fo...

i know all about hooking stuff up to a cia or bus - i'm a hardware engineer. i think it may be possible to get an IEC bus from the existing cia, and pushing up the speed wouldnt be a problem afterwards. that said, obviously i'm the only person actually interested in anything like this and your all h...

You can already convert a tape image to an MP3 and play it back on an MP3 player or over a sound card so I don't see a tape emulator as very useful and more expensive. Sure it might allow saving but you can capture to wave form with a sound card and convert it to an MP3 or tape image. You could add...

It should be possible with a transistor (maybe a fet) and 2 resistors... would have to look it up... The problem being the relay is NO (normaly open), and we don't have any Vcc handy on the plug... we could at worsetake it from printer port. i was thinking of an internal mod using the vsync signal ...

vsync cable.

just a quick question for people who have one,
does it mess with the tape loading so it has to be removed first?

if it does then why not just linik the sync output and the tape-relay signal through a nand gate or something so the sync signal is blocked when the tape runs?

hello people. had a lot of trouble signing up here, but now i managed: have you seen this? http://www.luigidifraia.com/c64/dc2n/index.html looks like a dropin to me. :) also: http://pontoppidan.info/lars/index.php?proj=mmc2iec not a dropin, but good enough to make me want to add an IEC interface to ...
