List of cores with ADC and RTC support

Unread post by pgimeno »

Is there one? I have been unable to find any.

From the release notes over at atari-forum and here, I've found the following cores are mentioned as supporting ADC.
  • Spectrum (tested myself)
  • Amstrad
  • Apple II
  • ADCTest
  • (Unofficial) MSX1
Update: From the comments in this thread and other sources:
  • Acorn Electron
  • Lynx 48 and 96
  • Oric
  • CoCo2
  • AliceMC10
Are there any more?

Similarly, I have not found a list of cores that support the RTC, and from the release notes I have found these:
  • Linux
  • Menu
  • Minimig
  • QL
  • Archie
  • NeoGeo
  • SNES?
  • GBA?
These were not mentioned anywhere, but I've used these cores and verified that the RTC works with them:
  • ao486
  • X68000
  • PC8801
  • MSX
Any help making this list more complete will be appreciated.

Hi,

I just got an ADC for my Mister. I have successfully tested it with the above mentioned Spectrum and Amstrad, and also with the Oric. It is supposed to work with the Dragon core, but doesn't.

Pretty sure it is not yet supported on Dragon as I was talking to author. I was trying to use a CASdunio tape loader (.cas to audio signal device) which i used with a real Dragon and MSX so I knew it worked.

Tapes ruled in 80s UK. 8-)

I don't think the Dragon core supports the ADC.
I've been trying to keep track of cores that support the ADC add-on in my Google Sheet.

Hi, thanks for the link to the Google Sheet. As the sheet says, it also works on the Acorn Electron. I just tested this this evening and it seems to work very well. I have not yet tried the Lynx core at all, but will probably get around to it eventually :)

I was under the impression that the Dragon was supposed to support it, but it seems I was wrong.

The ADC is brilliant. It really gives that 80s vibe. Interestingly, I get EXACTLY the same results using the ADC with the Spectrum core as I do with my real Spectrum. Exactly the same files work or don't work, in exactly the same way.

I had considered implementing this for the TRS-80 Model 1 core - and indeed, the current core takes the .CAS files and modulates them according to the original 500 baud timing, so it may not be such a big effort remaining.

But as I was also going through old tapes this past summer, I found that the combination of Audacity and WAV2CAS/CAS2WAV utilities was far easier to use than the original tape device had been (setting the tape level was always a big issue since there is no particular feedback on volume levels/distortion).

There might still be use in implementing it for non-native tape formats such as B-17 or TC-8 though.

I just recently got my ADC board, as I ordered the new acrylic case from misterfpga.co.uk, which has a hole for the connector. I was also looking for a list of cores that support it, glad to find it here.

I was hoping the VIC-20 core would work with it, but it doesn't seem to. Neither does the C64. Maybe it couldn't work, if it has to be able to pause the cassette player to function correctly. The Datasette has this functionality and if I remember correctly MSX computers (or was that the Spectrum?) have a remote control connection to do this, which works with a lot of regular cassette players.

A few posts up I have a link to my Google Sheet that I've been trying to keep track of cores that support the ADC or you can find the link in my signature (MiSTER RGB Sheet).

You should add the ADCTest core to the list of ADC support.
May be useful for setting volume levels and verifying functionality or tape quality, etc.

Just wanted to add that the NeoGeo core uses the RTC for the internal "Bookkeeping" feature so you can see when you played and how many credits you've put in!

The ADC Test Core is listed under the "Utilities" tab on the Google Sheet.
@dshadoff, thank you for the suggestion. I added your suggestion to the notes.

Oh, I hadn't noticed the tabs before. :)

The SNES and GBA both have RTC implemented, and the GB/GBC core has this added in branch and should be going into main very soon.

The Atari ST core could get it added, as people have added it to real hardware, so I raised a ticket.

The C64 could get RTC functionality on real hardware as well, so could potentially be added to the core.

It might be worth doing some digging to see what other cores could support RTC and ADC and making a list of those.
