First interrupt test on the #65c02 #homebrewcomputer passing. 🤓
The VIA Timer 1 has been setup to trigger interrupts every 65536 cycles, and at each timer interrupt a counter is increased and shown on the LEDs attached to PA and PB on the VIA.

Hey aksing for a friend does anyone have a use for and wants an Alphaserver4000 (+two external diskbays), HPVisualizeWS or a SunE250. We would send it to you for the shipping cost only if you like tinkering around with stuff like that.

A few photos from last Sat's @LpoolMakeFest event of our #TinyBASIC Computers display featuring @Sapphirewolf16 on stand!
The #PCBs were made for us by @PCBGOGOofficial
The colour system uses the 7" #LCD #wimaxit display by @Andycinegear as reviewed on our @YouTube channel.
