Matt EvansDon’t like the moon? Then read my new project post, especially if you like microcontrollers, emulators, and old Macintosh stuff. Zero moon chat here, guaranteed!
gadgetoid@Mattmos a Pico-based board with HDMI out and an integrated keyboard could make this *quite fun*! It’s a shame nobody is working on anything like that. 👀🤐
@gadgetoid 😁 or add TFT and BlackBerry form factor! But VGA-res LCDs are more expensive and then you may as well add RAM and then use one of the better FPGA Macs…wait I featurecreeped your idea 😬
@Mattmos ooof the BB Q20 (Solder Party) keyboard would be perfect!
Could try a cursor following magnify setup on a 320x240 display, but that would probably ruin the appeal.
@gadgetoid nice! And you could try one of those 3.5” VGA panels… (The PIO code is almost ready for LCDs, just needs the FIXMEs fixed to drive DE)
@Mattmos argh must not get nerd sniped. I'll just casually mention it to @Daft_Freak instead 😆

Jonathan ‘theJPster’ Pallant@gadgetoid @Mattmos how do you feel about an ATX form factor Pico board in a PC case?
I’m wondering how hard it would be to port from a 1 bit “DAC” to my 12 bit DAC.
@thejpster @gadgetoid eyyy there’s nowt analog about the lord’s 1bpp colour depth, aye.
(It’d need some hacking of the PIO code, looking at the Neotron pinout; it was a bit of a struggle getting out/set/sideset pins lined up but then also wanted to support clk/DE. If we replaced the flexible version with an inflexible version, it’ll work. :) just not OOTB.)

Gus@Mattmos Nice one! I see its doing the rounds on various sites as well. 😃
@projectgus 🙏 Thank you! Just woke up, reading 🤩
alphabetter@Mattmos how do you reckon the performance compares to a real Mac128? I played around with the BBC Micro emulator on the RP2040 and it was struggling. http://lushprojects.com/beebemulation/ Fun but not particularly usable.
@alphabetter Nice; I’ll take a look at the Beeb emulator, thanks. I think it’s about the same, maybe a little faster. I didn’t research a benchmark that runs on the 128K, there must be one though. Argh now I’m curious…. Will have to try benchmarking 🫠 It’ll be biased by the profile I measured to optimise it, ie a set of “popular” 68K instructions measured from running a few apps.

Great project, love that concept 👍
If you can port .dsk files at some point, I think it would be more appealing to geeks to make it compatible with SD cards. If there is a level shifter and few capacitors for the SD card slot, I think it will be fine.
@KayKoba Hey! Nice idea, SD fits the (very subjective!) threshold of cheapness and hackiness. And also of not being too much soldering or coding. :D
I think I can help you with designing the PCB. I liked your design concept. I think your unique kit will lower the barrier for users.
