G80-S v1.0 Boards In Production

That’s right boys and girls! The first production run of G80-S v1.0 board has been ordered, confirmed, and are currently in production.

Some of you may be wondering what changes were made between the Beta run and the v1.0 boards. Well, to answer that question, not many. Firstly, and the most important aspect, the IEI line has been fitted with a resistor to VCC. This will allow SIO/DART interrupts if desired. It doesn’t affect current G80-S software. The other changes were simply cosmetic changes to the silkscreen layer. Everything should look pretty now.

Once the boards arrive I’ll get them checked for issues, but the layout hasn’t changed. So the only issues, if any, should be cosmetic at this point. (I had put quite a bit of thought into the board when designing it).

Also, I have designed and ordered a first batch of prototyping boards for anyone who wants to tinker with other hardware. This board will have breakouts for both the z80 bus as well as the PIO pins.  And will have a place for a Micro-SD card and a 1117 3.3v regulator. These changes will simplify modification for CP/M or testing with other hardware by allowing the user a way to expand the board while keeping the same footprint.  With stackable headers you could add quite a few items to the computer.  Just food for thought.

Happy Computing!
