Hello,
It's time to start another Apple replica project – this time, a Lisa. It's a bit of a wild ride compared to the Apple 1 and Apple II, but I'll give it a try. I'll try to post photos of the work in progress. I ordered all the boards from Gerber, available online (many thanks to their authors).
The thread title is not accidental. There will probably be a separate thread about trying to get this thing to work :)
PCB Description:
1. Breakout board from https://github.com/RolandJuno/Lisa_Breakout

3. CPU card from https://github.com/warmech/lisa-hardware
4. I/O card from https://github.com/alexthecat123/Lisa-PCBs
5. 2MB RAM card from https://github.com/warmech/lisa-hardware
6. 2Port Parallel Card from https://github.com/alexthecat123/Lisa-PCBs
7. COP402 to COP421 adapter from http://john.ccac.rwth-aachen.de:8000/patrick/COPSreader.htm
8. 6309 to 27C512 adapter from https://github.com/RolandJuno/Lisa-PROM
Looks amazing to me, the cost you expect for it to be complete?
Hey, All the boards (5pcs of each) cost $310 (including shipping). I estimate the cost of the electronic parts to be an additional $300. I had most of it

Wow, you still can get PCB at an affordable price. Since the U.S. tariffs on Chinese goods, there is no way for us to get cheap PCBs for our hobby anymore. No way to build a 'Lisa' or any other clone. A lot of my own projects for the Apple-1 and Apple II hobbyist scene had to be put on the back burner due to the tariffs. Waiting for better times where it becomes feasable again to get reasonably priced PCBs.
Only for very small PCBs, not larger than an Altoids tin box, U.S. based, tariff free sources like OSHPARK make sense. The naked PCB for my YAAK keyboard - which from JLCPCB pre tariff did cost $6 each - if made by OSHPARK would cost $110 each. Makes no sense to do that. From this example I'd estimate (area wise) that a set of Lisa clone PCBs from OSHPARK would cost more than $500 per set.
Outrageous. Nobody would want to build a Lisa clone if the PCBs cost that much.
