I think I saw this book in a bookstore many years ago, but now I got it in a second-hand bookstore. No one read it ever. I don't buy books so old (1974), but I found this one interesting because it has a listing of a sample operating system in assembler for IBM/360. #retro #os

Yesterday's catch. Retro books from La Cuev Retro, my booth card, a Japanese Pokemon coin (thanks @bitorquesta.bsky.social ), a beaten Atari Portfolio, a mysterious Aquarius cartridge, and I hope Huevo (aka Rata Inmunda) got good use of $300,000 pesos given by Huevito 🤭 #retro #retrogaming

The Small-c v2 source code in the Dec/1982 magazine. The original owner drew with red ink. Along you can see how women will love you if you get an Epson printer, and the prices of memories in 1982. Notice no 8kx8 RAM available and the 2114 is economical (used in Colecovision)

I've searched for Dr. Dobb's Journal May 1980 magazine for many years. The planets aligned at last, and I got it along the December 1982 issue. The first issue contains the very first appearance of the influential Small-C compiler, and the other the 2nd version. #retro #magazines

This past weekend, I had a cold, so I setup my Intellivision and the ECS, along my all-new BASIC interpreter, and I coded 9 games. #retro #retrogaming #intellivision #basic forums.atariage.com/topic/385238...

But I bought it for the printer, because it is compatible with the Mattel Intellivision ECS. I built the missing cable, and guess what? It worked on the first try with my all-new BASIC interpreter for ECS 😀✌️ #retro #retrogaming #intellivision

The Aquarius computer works. Unfortunately, only half of the keyboard works so you cannot enter to BASIC, but I was able to play Astrosmash and Tron with one or the controllers. The other doesn't work. #retro #retrogaming #aquarius

I didn't need an Aquarius computer. But can you guess why I bought this set? 😉 #retro #retrogaming #Mattel #aquarius

I ported a Reversi game from Tim Harnell's Giant Book of Computer Games. Only changed screen, and array access from bidimensional to single dimension. #retro #retrogaming #intellivision

The final milestone to make it an useful BASIC: LOAD, SAVE, and VERIFY. Tested with real hardware using a PC as recorder/player. Now my interpreter is way superior to the original Mattel BASIC. Send it back in time and watch C64 crumble JK 😂 #retro #retrogaming #intellivision
