First of three new projects released: The #GalDiskII, sponsored by #PCBWay (thanks!)

An #Apple2 Disk II controller clone using a PLD in place of the P6A PROM.

It does away with the transistors used to turn on/off some ICs and introduces a few quality-of-life improvements I wanted (mainly the ability to configure it for the FloppyEmu dual-drive emulation mode).

It was built to help me test my P6A to 22V10 conversion, and is now the controller of choice for my //e clone.

Enjoy, it's free for everyone!

The Tauntingboard prototype now works! After a few fixes and bodges, all trivial, but I think it warrants another run just to check that I did not fuck up elsewhere by fixing rev.0.

Also thinking of replacing the Apple Garamond text with Motter Tektura, same I was advised to use on the GalDisk.

A reminder that there is a Game Lobby built into #FujiNet, offering access to cross-platform multi-player networked games! Press 'L' in CONFIG!

5 Card Stud, Battleship, Fujitzee, in an open API.

A post only a human could write: What if the #apple2 had run on Field-Sequential? (the kind with the spinning color filters)

Here are the reconstructed schematics of the #apple2 #SCSI Rev.C card:
https://codeberg.org/hkzlab/AppleII_SCSI_RevC_schematics

These will be the base for a clone I'll work on soon (SMD based, someone else is taking care of the THT).

Given that everything you see inside the repo is taken from the community, I am giving it back, in case someone else wants to have fun with the schematic and use it as a base for some #retrocomputing project.

Just be aware that I do NOT own a card, so I could not check every connection personally. Hopefully it's correct.

Ok, #apple2 #retrocomputing people of the fediverse, I need some help.

If any of you has a few minutes and an Apple II SCSI card (picture attached), I'd like some help to buzz out a connection.

You'll notice a ceramic disc capacitor, C7, near U2B (74LS08).
In the schematics I have, that cap is not present. I'd appreciate the following:

1. Value of the cap (or whatever is written on top) [looks like 331, 330pF]
2. Buzz out the connections: I guess one leg goes to GND, what about the other?

Thanks a lot everyone, boosts appreciated!
