IBM’s Frank King appeared on an October 1986 “Computer Chronicles” to demonstrate the IBM RT PC, a $10,000 RISC-based desktop computer with 4 MB of RAM, a 70 MB hard drive, and IBM’s proprietary UNIX, AIX, featuring the X Window System. https://www.computerchronicles.blog/computer-chronicles-revisited-065-ibm-rt-pc/ #retrocomputing #risc

hi, i'm ascetic ツ i run a small (but growing) self-hosted stack and make random things, mostly around retro computing, privacy, classic games and IRC. lately: pagerom, which turns any website or feed into an NES, SNES, or game boy cart you can actually playmodembin, which is pastebin but with real modem audio decoding to text and live modem chatan IRC server that bridges every possible protocol (even email, phone, obsidian) into one hubthis instance (which is just me) running snac on a tiny vpsbeen on the internet way too long. say hi, especially if you're still on IRC in 2026. the rest lives at https://system64.computer #Introduction #SelfHosting #RetroComputing #IRC #Privacy

@tiefling@bardicperspiration.club @DaimonRainbow@bardicperspiration.club I think that is why sites like Neocities exist (where op is hosting their blog, and this article).

Today we travel back to 1972 and run MYCIN, one of the first expert systems, on the Pentium 1. MYCIN was developed at Stanford University in the early 1970s to diagnose bacterial infections and recommend antibiotics. In 1979, it achieved a 90.9% agreement rate with Stanford experts. The system was built around roughly 450 production rules, each representing clinical decision criteria from infectious disease experts. So I got the code, installed CLISP on the Pentium 1 and started the consultation. There was one small compatibility issue: Peter Norvig's implementation uses two functions not defined in modern CLISP, requires and rest2. A short shim file fixed that and the inference engine came to life. The version available today is only a fragment of the original MYCIN. The implementation from Peter Norvig's book "Paradigms of AI Programming" contains the inference engine and just 6 rules for identifying organisms. The remaining rules for therapy, dosage and patient-specific recommendations are gone. The original MYCIN was written in Interlisp for a DEC PDP-10 running WAITS. It was never released as open source. What survives today is essentially the shell of the system, not the knowledge it contained. MYCIN is a monument to AI history. The way its source code was handled is both a memorial and a warning. ELIZA (1966) survived because Weizenbaum published the code. CLIPS (1985) survived because NASA released it as open source. MYCIN (1972) did not. Publicly funded research. Publicly funded code. Never released to the public. This is why publicly funded research should be open source.

I cannot recomend C64GUI highly enough. It's a basic GUI for the C64 which lets you: *Run programs and games with a simple double click *Manage files by cutting, copying, pasting, deleting, and renaming them *Format and rename disks *View files in text and hex mode *Create disk images and folders *etc... I make it my default cart! #retrocomputing #c64 #retrogaminghttps://github.com/WebFritzi/GUI64

@eri@plush.city beautiful finds in #retrocomputing

In this week's episode of Why Doesn't The Bloody Thing Work we'll take a look at this thing I just threw together on a whim from parts I had lying around. Well, TBH I had planned to build it sooner or later - it's the 1581 enhanced, a floppy disk drive for Commodore 8-bit machines using the 3.5 inch floppys we all know and love. What makes it special is that it can use normal wall wart for power, it doesn't need that special Commodore PSU with a DIN plug. The drive mech is a modified PC drive, and the case is 3D printed. I'm troubleshooting the freshly soldered mainboard here. Turns there was three reasons for it's nonfunctional state. #commodore #c1581 #retrocomputing

#commodore #c1581 #retrocomputing Reason number one was that it needs a ROM chip with the right stuff on it. In my befuddeled state I burned the EPROM, put it aside and made a label for it - and then grabbed another random EPROM lying around on my desk, put on the label on that one and tried using it. No luck with that. Turns out I had tried to use this hilariously fake 27c128 (or is that what it is?) - it's blank and the wrong kind. Took me an hour or so to figure that one out. I need to clean up my messy desk, I guess.

#commodore #c1581 #retrocomputing The next reason was not on me: The drive powered up all right, but when it was connected to my C128, I would never get a blinking cursor after the READY promt on the computer. It would simply hang. The C128 checks for a bootable disk when it starts, seemed like something failed during that process. After a bit of experimenting I found that the 74LS14s from this batch was the issue. All of them causes the same error. A desoldered 74LS14 from a scrap board fixed the issue right away. The funny thing is that these 74LS14s passes the logic IC test in my MiniPro. So it seems that they are 7414s of some kind, but I guess they're not LS parts...I think Noel from Noels Retro Lab on YouTube had a similiar issue with a logic chp in one of his videos. Seriously, what's the point of faking stuff like this?
