Wanted Cumana Disk Interface for +1 Cartridge Port : NO LONGER REQUIRED !

Post by BeebMan2018 » Wed May 15, 2019 12:26 pm

Hey Guys,

I've finally got a grotty +1 being shipped home to me. Well they haven't shipped it yet but i hope they will soon. I have paid for it however so i hope its good. Anyway. I have a spare disk drive knocking about and rather than save up to buy the rather expensive +3 i thought i might find a cheaper solution and buy the Cumana Disk Interface. So I am hoping someone out there has one or two surplus to requirements and that i can perhaps purchase it from them. Let me know if you have one and are willing to let it go ! Maybe we can make a deal.

Cumana is incompatible with standard disc formats. Added to that, most suffered battery rot so you're very unlikely to find one.

You should look for a Pegasus 400 or AP3/4 (Speak to daveejhitchins on here, he should be able to help?)

Can you tell me a little about those ? I have no clue. I had an MSX then an Amiga and for the past 20 odd years been a PC User.

They both do the same job, the circuitry is slightly different. They'll give you a disc system that doesn't play with the amount of memory available (DFS) and is compatible with all of the ssd/dsd disc images you'll find lying around, and the option of also adding an ADFS ROM which gives compatibility with ADFS discs (double density, 320/640k). This will chew up your memory somewhat.
