Quote from: bleeper on 14:03, 12 June 10I'm still wondering though, if I actually need to have it switchable, or if Parados will perform anything Amsdos can?
Quote from: bleeper on 15:52, 11 June 10I've been reading the Wiki and this seems like a good ROM to have in place of Amsdos. However, I don't have the means to produce one myself so would like to buy one, and was also wondering if there is any downsides to using Parados? Is compatibility identical?
Quote from: TFM/FS on 23:12, 23 June 10Instead of Parados I use the XD-DOS, it contains a lot of usefull additional commands, supports even the HD20 hard-disc and naturally the Vortex format.
Quote from: Executioner on 03:22, 24 June 10Yeah, it supports the German Vortex format and the HD20, but does it support DS80 Data/System and ROMDOS formats which are the most common outside Germany.
Quote from: sixonetwoeight on 20:35, 21 July 10Does anyone know what's the chip enable pin of AMSDOS / Parados? Piggybacking might be a messy solution but it's also cheap :-)
Quote from: archcosmo on 13:27, 24 July 10I prefer to make my own eprom and use a switch to enable Parados
Quote from: xesrjb on 17:31, 24 July 10I solder an 27512 in my CPC:1. AMSDOS;2. Vortex 2.11;3. DDOS (720kB Dos from Dobbertin, but the CPC has to run as a 464 not as a 6128),4. Parados 1.3 (Patched Parados 1.1 that run in a 2 x 720kB Mode.xesrjb
Quote from: Bryce on 22:48, 21 July 10 There's no Chip Enable, but they do have a Chip Select (Pin 20) and an Output Enable (Pin 22). For true compatibility, you'll need to use a 2 pole switch to switch both signals between Original and piggy-backed chip, all other pins can be directly connected in parallel.
Quote from: OCT on 16:09, 24 July 10From your second image I gather you are using an EPROM of double capacity but identical pin count, probably switching an address line between GND and +5V to toggle the appropriate "half" ?Could you provide some more details on this for the readers who do not have ParaDOS installed (piggyback or otherwise) yet?
