I'm pleased to announce that the new revision of the MiniPerformer+ for the #macplus arrived, got assembled and worked at the first try!
No bodges or cuts in this one!
Will probably have some free time in the weekend to write some docs and release everything!
Anyone know what the CRT refresh rate on the original Mac / Fat Mac / Mac Plus is? 60Hz?
Got my BlueSCSI from @onegeekarmy today! Really happy with it. I can’t use it right now (the Mac is disassembled waiting for a cleaning session), but will soon.

hey #RetroComputing peeps! i've got a #MacPlus that i can't introduce my sons to, because we lost the mouse ball for it. there are lots of mouse balls on ebay - i bought some - only to find they are the wrong size! what is the diameter of a #m0100 mouse ball? and how do you make a mouse ball?

Rewired an Amiga mouse for the #MacPlus clone. Still can't type, but at least I can click around as much as I want now.
And confirm that all the 4,096K are detected!
So, another nice update on the #MacPlus clone.
Two updates, actually.
1st: I forgot that I had an "old" SCSI2SD around, pulled it out and the Mac was able to boot from it! Quite cumbersome as a setup, though.
2nd: The PLCC adapter for the 5380 works! Will release it soon-ish.
And now, thanks to @DosFox, the #MacPlus clone boots with 4x1MB banks, and it accepts banks with 4-bit Dreams just fine (well, actually it complained about some Samsung sticks, but I suspect them to be defective).
Where to go from here?
- I need to replace the 'LS253 with ones from the F family
- I need something to boot from. I do have SCSI adapters around, no idea if they play fine with Mac. I think I'll just go with a BlueSCSI, either bought or built.
- I need something to move the mouse, maybe adapting an Amiga mouse or using this https://github.com/Black-FX/RP2040_Mouse_KiCAD
- I need a keyboard adapter
The road is still a long one!
Hmmm crap. Seems I have loads of "2 chips" (+ parity) 1MB SIMM modules but just 3x 256K modules and just 2x 1MB "1bit ram" modules.
From what I gather around, the modules with 4-bit chips seems to be incompatible.
Can anyone confirm?
Otherwise I'll try to bring up the #MacPlus clone with either 2MB or 512K
More ICs in the #MacPlus clone, including the GALs, but I'm still missing 5x 74F253 (I have plenty of 'LS253, but I suspect the F ones are there for a reason) and 2x LS166.
I'm still searching between all my scrap.
That's enough ICs for today.
I don't trust that resurfaced SCSI IC, but I have old PLCC ones and I made an adapter. Can try those if needed.
I also lack the 'F253s (I have loads of 'LS253 though...), the '161 and '166. Will have to order them at the end of the month.
Tomorrow I'll have a look at the GALs I can use for the PLDs. #MacPlus
Finally, the SIMM sockets are soldered to the #MacPlus motherboard. They were the last thing that needed soldering.
Now, to start plugging things in...
