Not that it has anything to do with anything in this video, but if anyone is interested in what can be done using TTL logic and a lot of PROMs, please consider looking at Professor Matt Regan's KZfaq channel. Here's a link to his TTL based (i.e. *NO* 6502 micro, but lots of PROMs and a bit of TTL) Apple II system: < kzfaq.info/get/bejne/nt51eMmExt-2fqM.html >

Everything you guys talked about in networking is part of the IEEE ethernet standard except for the Apple stuff, however AppleTalk protocol can run over ethernet.

For some reason, during the board game discussion when 'Turtles' was mentioned, I immediately thought of the programming teaching tool. Probably since I was unfamiliar with the video game.

FP! The Intellivision came out in 1979 and the Aquarius came out in 1983. I've never seen an Intelly overlay worn, dented, creased or lost but never worn. The art was on the inside...

I really should know better than to listen to the Roundtable's members inane prattle, but this video showed up in my KZfaq recommendations for some reason. FWIW, here are a few comments from someone who is familiar with Univac and TV teletype writers: First, WRT to Quinn's comments about Univac, it became part of the Sperry Corporation and so was referred to as "Sperry Univac" until the Company decided change its designation to "Univac, a division of the Sperry Corporation" and then simply "Sperry" to emphasize the Sperry name. Burroughs took over Sperry in 1986 and the result was renamed "Unisys". Unisys still exists today. Both predecessor companies made significant contributions to the history of computers and I find it annoying to hear someone who openly admits to not knowing much (if anything) about computers before the Apple II (most notably mainframes) taking pot shots at either of them for having been around back when computers used vacuum tubes ... as if that's where they stopped developing. And, no, the Apple IIGS did *NOT* do in the Univac or Sperry Univac or Sperry or even reel-to-reel tape drives. Again, Univac/Sperry Univac/Sperry continues on to this day in the form of Unisys, although the "mainframes" they "produce" are emulators that run on Intel servers. As for the tape drives, I recall shooting rubber bands at the buttons on the control panel of such drives (a U36N?) to get the window to slide up or down long after 1986. I used to be very good at it. And I would note for the young ones in the audience that the World is *STILL* reliant on "dusty deck" programs (often times written in COBOL) written to run on mainframes, especially in the banking industry. Second, WRT to Don Lancaster and his series of TV Teletypes (TVT), he made a series of TVTs, not just the one described in the book (which IIRC was the TYT-2). The last one IIR was the TVT-6 in which he replaced a lot of the logic with a 6502 which just happened to be a part of a KIM-1. You can still find the schematics and code (including the original "Popular Electronics" articles ... there were three IIRC) online. To the extent that he used old chips that you can't find today, about the only thing that might fall into that category is a character generator ROM chip which when fed in a scan line number would return a bit mask of the bits set in that line of a character. This can (relatively easily) be reproduced with a little programming and an EEPROM (and programmer) as Ben Eater pretty much did in his breadboard computer project. I *THINK* his TVT-2 was only TTL and CMOS (a couple of Lancaster's other books being "The TTL Cookbook" and "The CMOS Cookbook") except for the character generator chip or chips. Certainly, generating the signal chain for a TV signal can be done using just TTL chips as was shown by in the April 1977 issue of "Radio Electronics" which featured the construction of a single board micro based on the Signetics 2650 (not 6502 as is occasionally incorrectly stated elsewhere). Except for a roughly 14MHz crystal whose frequency might be odd today, there was nothing special about the chips in the signal generator. And since a VGA signal is relatively close to a TV signal, there's nothing particularly problematic about making a TVT today. If you want to save yourself some logic, you can probably get there from here using a Parallax Propeller chip which I'm pretty sure is still available at Digi-Key. OBTW, I think that the chip that Quinn is thinking of is the Motorola MC6845, not 6851, which was a popular *CRT Controller* chip. I don't recall it being at the heart of any of Don Lancaster's TVTs. I suspect that a TI TMS9918 would have been a better fit as it was supposedly intended for an NTSC display although it wasn't used either. As for the use of a TVT, yes, it could be useful to talk to a mainframe if you had an acoustic coupler, but even more important was to use it to talk to your homebrew micros which began to use a serial TTY-like terminal instead of switches and lights. It is simply fucking amazing to hear people who are supposedly into retro computing talk as if the beginning of (micro) computing sprang into existence with the Apple while apparently being completely ignoring the fact that there micros before the Apple II (e.g. the Mark-8 and Altair 8800 not to mention any number of homebrew systems) and not everyone had a Teletype 33 laying around to talk to them.

Sump pumps are also used for high water tables: the basement floor is lower than standing water in the ground. The water always exerts pressure on the basement floor until it finds a crack in the concrete. That under-the-floor drainage pipe to the sump pit just constantly drains the rising underground water, and the pump gets it out of the house. My last house in Illinois had a sump pump that ran consistently (5 minutes off, 30 seconds on) even in the driest of droughts.

It's editing backlog, it will be published. We've recorded a few more than have made it to the audio feed yet, but the hope is that we'll be caught up soon. Working on it! The next one for the feed is about 75% edited. We're planning to add to the backlog in a few days, but we're striving to have one or more of the already recorded ones hit the audio feed before that.

The talk about having two sector 0's on the same track, and it booting differently depending on which one passed under the head first reminds me of the multi-ending flexi-disc record that MAD magazine put out in the 1980 - "Super Spectacular Day", which I had back in the day. The first part of the song played the same, but the second part of the song was a random one from 7. Like the sector 0 you mentioned above, it had multiple paths the needle could follow, so which ending you heard depended on which groove the stylus landed on.

@retrocomputingroundtable44457 ай бұрын
I think if you subscribe to the channel it will notify you when we schedule a live broadcast. We often don't know ourselves whether we're going to record or not much in advance, but when we record it is always at Sunday around 3pm or 4pm, New York time. We usually manage to send the notifications a couple of hours ahead of when we start, and toot it out on Mastodon here: podcasts.social/@rcrpodcast - but, you're right, we should make that information more obvious somewhere. These really are conceptually the "behind the scenes-making of" documentary of the audio podcast product, rather than being a show in its own right. So you don't get the editing, nicer audio, ad breaks, but it does have the advantage of being real time, so you can help correct our errors as we go!

There is a Commodore IEC Fujinet that shares the same dev board with the Apple II. There is a partnership between the Meatloaf project & Fujinet to bring the Meatloaf functionality (in large part) to Fujinet. The Commodore Fujinet is still under development but it does (mostly) work. I think they're still ironing out some details around IEC timings.

And, in one of the opening screens of text it says "now, I wouldn't go shooting at a chest full of explosives....." which in my impatience I actually did a few times as I "shot down" the time on a chest.

Hi, thanks. I don't think we have much control over what Streamyard sends to YT when we record live. When the audio is edited down for the podcast stream, the individual speaker volumes get balanced pretty aggressively. So on the audio podcast feed it should sound fine. But thanks for alerting us to it anyway, next time we record, we can see if there's anything we can do to balance our volumes. My (Paul's) mic is fundamentally pretty quiet, I have it cranked up to max manually within Streamyard.
