[Dirk] posted a video (you’ll see beneath) titled, “Mystery Retro Project Start.” That grew to become out to be the primary of a multipart sequence on his Altair 8800 Again simulator. The entrance panel seems to be laser lower and in some long term video episodes, we predict to peer him simulate the CPU with a Teensy.
There had been various 8800 clones starting from initiatives that recreate the unique PCBs, to those who simply run a Raspberry Pi inside of. The heart floor will use an Arduino or another small CPU to simulate the 8080 CPU.
The switches are multiplexed which isn’t unusual. However, the LEDs are in reality an addressable LED strip. We’ve constructed a equivalent panel with discrete LEDs and we will attest that the usage of the strip goes to be more straightforward. Besides that, it lets you alternate the LED colour to fit your decor, one thing the previous 8800 may now not do and not using a soldering iron.
The drawback, in fact, is that you’ll replace the LEDs at precisely the similar time. For maximum issues that’s most probably now not going to subject a lot, however it’s nonetheless somewhat little bit of a departure from the unique pc.
Even with out emulation, this may be a excellent get started for a panel to hook up with SIMH working on a PC. The use of the LED strips and the laser cutter make this so much more straightforward than maximum different builds we’ve noticed.
We at all times take into accounts the Altair across the finish of the 12 months for the reason that unique confirmed up within the(which might be on newsstands in December).
If you don’t have the persistence to construct a complete entrance panel, you’llas a substitute. In truth, we’d be tempted to construct a sequence of PCBs to mount at the back of the panel. We’ve noticed that way .
