Here's the roundup of our posts for January. Comments welcome on this thread! Check the original posts on gplus for comments too. (See also our previous roundups and our profile page.)

2018-01-05 - the 6502 as a trusted compute platform, for nuclear weapons treaty verification.


2018-01-12 - a completely wireless (emulated) Apple I, on the tiny inexpensive ESP8266.


2018-01-19 - Stella at 20, the 1997 documentary and additional footage, featuring many Atari luminaries.


2018-01-26 - Pear and Orange, two Apple II clones from back in the day.

Thanks so much for posting these each month BigEd

You're welcome! I have to say, I've had a bit of a slack performance this month - I might be running out of steam.

I found more info on the Pear II here. It looks like it was a quite capable Apple ][ clone.

Edit: Here's the URL https://www.1000bit.it/scheda.asp?id=2542

And a couple more articles I found...

An interesting time, when various companies thought it might be fair game to copy Apple's machine - and the legalities weren't entirely settled as to what was and wasn't protected.

Here's the roundup of our posts for February. This month we mixed it up a bit - we started a #SixFiveOhTuesday hashtag and we posted several times in the Retro Computing community on G+.

2018-02-14 - Two 6502 workalikes in TTL running at 20MHz - one from the chess machine wars, the other from this very forum.



2018-02-18 - Dolo Miah's breadboard and high level language DFlat



2018-02-20 - Apple II and BBC B in TNMoC's Fibonacci Challenge



2018-02-23 - Java Grinder, for C64 and even for Atari 2600



2018-02-27 - The Ohio Scientific - another from 1977

A bit random that my build is mentioned with quite an old picture, but happy for the reference!

Happy to feature it! (The G+ interface isn't always very helpful at choosing which images are available - there were a couple of preferable ones for the Fibonacci challenge which weren't readily usable. But the breadboard image is colourful and attractive, which counts for a lot on social media.)

Yes good point, that picture does look more interesting than now as it's partially obscured by the keyboard and keyboard interface. Thanks again

That's great. That's really clever.

Here's the roundup of our posts for March - rather more than usual since the advent of #SixFiveOhTuesday. Comments welcome on this thread! Check the original posts on gplus for comments too. (See also our previous roundups and our profile page - or look here.)

2018-03-02 - The $130 PE6502 hobby computer kit, like an Apple 1 but slightly improved, and all through-hole.



2018-03-06 - a Sudoku puzzle solver for your Atari 8 bit, with heuristics and backtracking, and with source available.



2018-03-09 - the VIC-20 as seen in a press advert, featuring William Shatner.



2018-03-13 - David Schmenk's Apple II Pi project, which puts a Pi on an expansion card inside an Apple II, for multifarious purposes.



2018-03-18 - from 1979, the CLUSTER/ONE multi-computer network using a PET as a central server, and using IEEE-488 cables to string the various micros together.



2018-03-20 - a look at various disk sector editors for the C64



2018-03-23 - Steve Gray's roundup, with photos, of various graphics boards, colour boards, 80 column boards, mostly for the PET.



2018-03-27 - a look back at the UK's Computer Literacy Project, which brought us Acorn's BBC Microcomputer and gave Acorn a healthy shove forwards in credibility and market share, and annoyed Clive Sinclair quite a bit.



2018-03-30 - a VIC-II chip emulated with a microcontroller, not cycle accurate but an interesting approach.

(I've only rounded up the posts made by the mos6502 account - there are more #SixFiveOhTuesday contributions at the hashtag.)

Ah, the good old days, when computer hardware wasn't so opaque and difficult to understand.
