Tom if you’d want to let me test that prototype board in my 8800c I’d be more than happy :)
Also I’ve visited your site now — so much to see there! I’ll get back to you about it after I’ve consumed more. But I can already recommend http://www.virtualaltair.com to anyone who hasn’t seen it yet.
And to all, I’ve just completed this 88-VI(RTC) board from one of the bare reproduction boards available from JM Precision Components in the UK. Finding all the parts was like going on a journey, but not too bad at all and kind of fun.
I’m hoping to get Timesharing BASIC going with it.
