Excellent YT series:

I bought a KIM Uno from Oscar at VCFMW years ago. I just retired and finally found the time to build it. I'm running his 1802 Pixie code with a SSD1315 OLED and find that the page displays are shifted up 4 rows with wrap-around. I added this kludge to the paintscreen() inner loop: uint8_t a =...

Someone ported subLOGIC's T80-FS1 to the Sorcerer but left the display as 16 lines, squashed in the lower half of the screen. I modified that port to use the full 30 lines on the Sorcerer. Two side benefits are corrected aspect ratio and double vertical resolution. No code was changed, just...

Have any of you used this? Is a disk image available?

The Wang 2200 was a popular minicomputer in the early 70s with built-in CRT, keyboard, cassette, and BASIC in ROM. Did its design have much influence on later microcomputers?

The question of the first commercially available personal computer has had several answers: Kenbak, Altair, Apple. One machine, offered in 1974 for $795, with 200 bytes of RAM, 4K bytes of ROM, a high level language with intuitive UI and floating point math library, including keyboard, display...

Forty years ago, before internet forums, there were user group newsletters. The TI programmable calculator hackers would write about their discoveries concerning internal workings of those little machines, particularly the SR-52, SR-56, TI-58, and TI-59. The TI-57 and lesser models were more...

Have a look at this Scarfe animation for Pink Floyd from 1975: https://www.youtube.com/watch?v=fBAtYWT7wEs Starting at 6:46 is a spherical maze sequence which has enough geometrical precision to look computer-generated. I'm not suggesting the film was CGI - it's obviously traditionally animated...

I just read Sol Libes' article in the July 1978 BYTE: THE FIRST TEN YEARS OF AMATEUR COMPUTING. https://archive.org/details/byte-magazine-1978-07 It mentioned the Amateur Computer Society, the original homebrewers. http://www.atarimagazines.com/creative/v10n11/6_The_early_days_of_persona.php...

BYTE covered a new kind of microcomputer they called "appliance computers". Here are some compilations: http://atariage.com/forums/topic/262195-40-years/

Haslett is near Lansing. The first computers I used were a Honeywell 200 and two Altair 8800a's. The first computers I owned were TI Programmable calculators and Atari 8-bits. I collect 70s programmable calculators, Atari 8-bits, Sinclair/Timex, Apple, and Exidy...

Untested, as is: 1 Everex ISA '386-20 with full DRAM and SRAM and '387, clean in original packing 1 ISA Am386-25 with no RAM with Cyrix FasMath '387-25 2 ISA '486DX-33 with full DRAM and SRAM Can post photos if you're interested.

I found the joy of computers in high school in 1975. The first one I owned was a TI SR-56 in 1977. Then Ataris and others. Here's my geek site. I have been on the AtariAge forums and the Museum of HP Calculators forum but would like to find one for TI programmable calculator enthusiasts. Could...

Are there any TI programmable calculator collectors or enthusiasts here? My first personal computer was a TI SR-56 in 1977. It had a whopping 0.3K RAM but it was fantastic then. Here's my collection site with links to several excellent sites.
