Second attempt at the external 4mb expansion for the #SamCoupe and it works perfectly. Decided to give #JLCPCB a try just because I couldn't bear waiting another month for #PCBWay to deliver to find out if the new design worked, and they weren't too far away on pricing. Placed the order on 26th April, it arrived today. That's not bad going at all.

#TauntingBoard has finally been released!
It's an #Apple2 #MockingBoard clone(ish) with a few changes I'd dare call improvements.

It's free for everyone: print it, build it, enjoy it.

Thanks for #PCBWay for sponsoring not one, but two prototype runs for this board!

Boost if you wish (appreciated!) and/or donate a few credits via Ko-Fi if you want and have some to spare (Not essential, but they'll be used to help pay for components for future projects: believe me, they're helpful, vet expenses are eating away most of disposable income lately).

Rev. 2 of the tauntingboard ( #Apple2 mockingboard clone with a few improvements for my use cases) has been submitted to #PCBWay for sponsorship evaluation.

We'll see tomorrow.

If lucky enough, I expect to be able to release this to you all by the end of the month.

In other news, I'm terribly behind schedule today.

Finally, the #MiSCUSI is released!
https://codeberg.org/hkzlab/MiSCUSI_AppleII

For the newcomers, it's a rebuild of the Apple II #SCSI card, made with SMD components.

Tested it on my #Delta Apple //e clone with a #BlueSCSI

Thanks to #PCBWay for sponsoring this,and thanks to @DosFox for testing the PLD dumps on his card!

As usual, if you like my projects and have some credits to spare, you can throw me a few via Ko-Fi. It's not strictly necessary, but all go towards the next projects (instead of using what's left after I have fed and medicated the cat colony I inherited...).

*squeee*

Prototype external 4MB board for the #SamCoupé is marked as shipped from #PCBWay.

Now we play the "will #DHL deliver it before the weekend" watching game...

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!
If you want to support me, a few credits on https://ko-fi.com/hkzlab are always appreciated!

The trio of boards sponsored by #PCBWay arrived! It is now time to start soldering.

I'll begin with the GalDisk II, a Disk II controller using a GAL22V10 in place of the P6A PROM.
