»That means by 1975, the number of components per integrated circuit for minimum cost will be 65.000. I believe that such a large circuit can be built on a single wafer.«

found a wonderful little game preservation site devoted to early IBM/Tandy booters and PCjr cartridge images. original disk images can be often difficult to track down, as people often upload dumps made from cracked diskettes.
🛠️🍏 Next week, our volunteer Andrés will begin assembling a museum replica of the Apple I computer. It's an "open lab," so feel free to get hands-on, as it will take place in the classroom on the 1st floor. All are welcome!
in which I play a very recently found piece of lost media
Escape for Colditz, a 1981 adventure by Sharpsoft that tries to be an adventure game and a strategy game at the same time, and fails, but it's still interesting what it tried to do
Interesting fault: After playing around with my childhood C64 breadbin from 1983, the screen suddenly lost all contrast and went very dark. #retrocomputing#commodore#c64 1/3
#CGAPrints update: Release Candidate 1? I took some time today to test-print a couple of colours that arrived this week, and they seem pretty close. This is the first time I've compared a full batch against colours on a real screen - what do you think?
All 16 colours are different brands and types of PLA, so given access to the complete palette, basically every printer should be capable of making some form or other of CGA pixel art.
Needs a clean but I'm told it works. Peering inside, no battery leakage and caps look okay - though there's lots of dust. Slight cracks on front cover but otherwise intact.
Finally found some time to work on my #AppleLisaClone – the clone CPU board seems to work in my original 2/10. However, the Lisa complains about I/O error 51 (parallel ports VIA) or I/O error 1 (undef'd) or hangs with the hourglass cursor. With the clone CPU, I cannot power down using the power button, this works with the original CPU. The floppy needs fixing and my clone parport board seems to have a problem (static on screen when it's inserted, see video) – lots of work ahead! #retrocomputing
I’ve been rebuilding a #RaspberryPi installation that supports my classic Mac habit 😄
I used to use the awesome #MacIPGW image which includes a ton of pre-configured software like #netatalk. But it hasn’t been updated in a while so I used it as excuse to start from scratch.
I used this Pi Zero W as my starting point. HDMI video stopped working on it for unknown reasons. I added an Ethernet/USB hub hat and a #TashTalk 2 hat for #LocalTalk devices.
As promised, I wrote a blog post about creating my own classic Mac support server using a Raspberry Pi Zero, a TashTalk 2 hat, netatalk, and a few other tools. It's very much like MacIPRpi with everything current.
