Building your own ZX80 (and ZX81)
In case you're missing the wonders of mighty Blighty's original low cost 8-bit computing device, as conceived by Sir Clive Sinclair in 1980 – or never had a chance to get your hands on one in the first place – there is a modern clone board, so that we may get a second chance to experience the venerable ZX80 (as in "zed ex"), or even use it with the ROM of its popular successor, the ZX81. The board in question is the Minstrel by Tynemouth Software, available for just $20 (https://www.tindie.com/products/tynemouthsw/minstrel-zx80-clone/) and we had it already covered in a previous post: https://plus.google.com/109623937140604533680/posts/FZRwpYKFYmW

Now there's a nice YouTube video explaining the PCB and the modifications made to the original machine, showing the assembly and how to insert it into the case of a defunced ZX81 (with appropriate ornamentation). Moreover, the video description includes a parts list and where to find them, and even links to circuit diagrams and schematics, as well as layouts for decals ready to print.

How Apple made their way into (US) education - which was surely a great strategy for increasing their mindshare and then their market share. It's not all about VisiCalc!

AT&T Blit Terminal
Here's a nice, recently restored Blit terminal by AT&T: https://imgur.com/gallery/fWL5i (related reddit-feed: https://www.reddit.com/r/retrobattlestations/comments/6ydm2k/recent_restore_att_3b2_unix_minicomputer_w_early/). Blit, short for Bell Labs Intelligent Terminal, was an early GUI environment and bitmapped graphics terminal for Unix by Bell Labs, which was eventually commercialized for use with teletype terminals.
(Compare https://en.wikipedia.org/wiki/Blit_%28computer_terminal%29)

Is there anyone with first-hand experience with this system?

4 lessons for modern software developers from 1970s mainframe programming

Is 8 GB RAM cramping your style? Try writing headless programs that run in an 8 MB virtual machine, where it costs a fortune each time a program has a non-terminating loop. Current programmers should adopt several attitudes that early mainframe developers considered an essential part of their skillsets.

A wonderful minicomputer which very nearly saw the light of day, among other inventions of this interesting character: Jacek Karpiński. (Actually, it sounds like a few tens of prototypes might have escaped into the world.)

Many retrocomputer systems, old and new, from today's visit to The +Centre for Computing History in Cambridge. It seems I missed the C65 that was there. Among others I did see: Apple I, Apple III, SCELBI, ELF, Pied Piper, PDP8, PDP11, Jupiter ACE. Also a couple of interesting FPGA projects: Neal Crook with a 6809-based system, running a BCPL compiler on Fuzix, and Ken Boak with the BlackIce board running several systems (BBC Micro, Jupiter ACE, Z80 CP/M system.) Also also the RC2014 mini backplane and mini mini single board computer, which takes a Z80 by default but can be adapted to take a 6502.

Today and tomorrow, the Retro Computer Festival 2017 at +The Centre for Computing History in Cambridge UK - will you be there? I'll be there Sunday (tomorrow.) This is the final event of the CCH's Summer of Computer Love which ran over the school holidays. Lots of exhibitors, including James Newman demonstrating his MegaProcessor, the machine seen here.

This was very much my dream: Basic, and high resolution graphics. This is what computers can do! And you could have your own!
