Successful upgrade of my SC140 to RomWBW 3.5.1 😃 #8bit #RetroComputing #z80 #z180 #cpm

Successful upgrade of my SC126 to RomWBW 3.5.1 😃 next one on the bench is the SC140. #8bit #RetroComputing #z80 #z180 #cpm

My Commodore 64C just got a lot more fun to use 😃 by adding the brilliant Pi1541 Zero cartridge! What an upgrade from the datasette 📼 #8bit #RetroComputing #c64

Slightly more retro than usual 😀 but fun! And kudos to those 17th and 18th century engineers for figuring this out …

Intel's 386 processor (1985) moved the x86 architecture to 32 bits, but it needed to be backward compatible with earlier 16 and 8-bit processors. As a result, it needed complicated circuitry for its internal registers: six different circuits for 30 registers. Let's look at the silicon circuits. 1/N

A die photo of the Intel 386 processor under the microscope. The die has complex patterns that make up the different parts of the chip. The various blocks are roughly rectangular with different textures.
The main functional blocks are labeled, including the paging unit, bus interface unit, prefetch unit, segment unit, instruction decode unit, protection test unit, data unit, and control unit. The register file, the subject of this thread, is in the lower left corner, highlighted by a red rectangle. This die photo image has a purple tint.

My C64 just got the best digital video output I could ever dream of. The VIC-II-Dizer and an RGB2HDMI bought from c0pperdragon. This is definitely a 5-star rated solution. Excellent. (unfortunately the photo of the screen doesn't really capture how good the picture is) #c64 #8bit #retrocomputing

This is so much better than PDF files 😃 got this original handbook today! The book is from 1980 but in good condition. #hp41cv

I am happy that I managed to revive this HP-41CV which I picked up very cheap because of heavy leakage from the batteries. Thorough cleaning and a new battery/port bay and screw mounts made the difference! Have to mention this HP-41CV is 41 years old 😃 #RetroComputing #vintagecalculators #hp #hp41c

"Fly me to the moon" - the Apollo Guidance Computer was basically build on this resistor-transistor NOR gate, each IC containing 3 or 6 transistors, forming either a single 3-input NOR chip, or a double 3-input NOR chip. #RetroComputing #Apollo #AGC

I really needed this one in my Linux bash. Maybe I do a little too much CP/M stuff 😀 alias era='rm' #RetroComputing #cpm #z80

XMAS light time! NAND gate lights up when one or both inputs are low. No light when both inputs are high. #RetroComputing #digital #logic

Test run of Spectrum Forth on The Spectrum, seems to run as expected 😀 #RetroComputing #thespectrum #forth #zxspectrum

Amazon delivered some interesting reads for me, at quite different levels of abstraction 😀 #RetroComputing #z80 #thespectrum #zxspectrum

Got this 1982 HP-10C today in very good condition 😃 I didn't have one in my "Voyager" collection so happy to find such a good one 💎 #RetroComputing #hp #vintagecalculators

I love being a "full-stack developer" in retrocomputing 😂 #RetroComputing #basic

Latest firmware update 1.0.2 installed in The Spectrum. It was a very easy task 😀 #RetroComputing #thespectrum #zxspectrum #z80

Mogens B @mogensb.bsky.social · 26/11/2024

The Spectrum is loaded with some real ROM images 😃 I am happy to find out this is a feature! I am getting more and more impressed by this machine. #RetroComputing #thespectrum #zxspectrum

I recently saw an amazing Navajo rug at the National Gallery of Art. It looks abstract at first, but it is a detailed representation of the Intel Pentium processor. Called "Replica of a Chip", it was created in 1994 by Marilou Schultz, a Navajo/Diné weaver and math teacher. 1/n

A Navajo rug with a complex pattern with muted reds, pinks and blues. The pattern consists of various vertical and horizontal rectangles with stripes. Around the border are small alternating black and colored rectangles. The weaving is mounted in a wooden frame and hanging on the museum wall.

Just loaded Zeus assembler on my new speccy. Looks good, hdmi is slightly better than rf modulation 😂 I actually used a 12" B/W TV with my 16k ZX Spectrum back in the days #RetroComputing #thespectrum

Even the weight of The Spectrum is close to the original. 510 gram versus roughly 570 for the Sinclair ZX Spectrum. #RetroComputing

First run on The Spectrum 😃 I am impressed by the physical appearance, it is a very accurate replica, including the keyboard! It's a long time since I touched the original ZX Spectrum but this is really good and feels the way I remember. #RetroComputing

It's hard to think of a better way to start the weekend, I am really excited to unbox, setup and relive some very good memories from the '80s with The Spectrum computer. I learned so much about programming from my 16K ZX Spectrum back then. #8bit #RetroComputing #Z80 #ZXSpectrum #TheSpectrum

Here's a favorite of mine 😃 the simple but nevertheless very capable SC114 Z80 system running CP/M. Design and kit by Steve Cousins. #RetroComputing #Z80 #CPM

I hope this will be my future platform for posting and reading all kinds of retrocomputing stuff! #8bit #RetroComputing #z80
