Teletype on ebay

https://www.ebay.com/itm/225037349724 looks to be a ASR-35 (Heavy duty ASCII) The outside is so dirty that I can't read the keyboard markings, to eliminate it being a model 28 , but it looks good on the inside. The reader seems to be 8 bits wide which would make it an ASR-35. only 2 days left with no bid , I would hate to see it be junked. -- DuaneCraps sdɐɹɔ ǝuɐnp

Need help with audio processing from VCF West 6 (2003)
by Jeffrey Brace 22 Jun '22

22 Jun '22

Kay Savetz was able to successfully recover most of the talks from VCF 6 2003 with the help of Clay Cowgill. There are still some talks that are troublesome, so we are looking someone who is an expert at magically transforming audio issues. The issue as described to me is as follows: The audio is in WAV format, recorded poorly. Needs filtering, EQ, and magic. Audio levels range from normal to extremely low. Some of the audio levels seem to fade in and out even within the same sentence. Noise includes a 60hZ hum, and sometimes buzzy static — sometimes the static is significantly louder than the voice. Speaker sometimes too far away from the microphone. In summary, the audio ranges from “not bad, but I wish that buzzing would go away” to “what? what did they say?” If you know of someone that can help, then please let me know.

VCF East 2022 Videos coming soon
by Jeffrey Brace 22 Jun '22

22 Jun '22

Just keeping everyone updated. It's taking me longer than expected to review all the videos from the show. Ethan O'Toole and crew did a great job of recording it and Kay Savetz has done a great job editing and processing all of them. Life, work and other VCF activities have delayed for me. I'm reviewing the last video, then I will be making an intro that will be appended to each video. Something like 15 seconds long. I hope to have the videos released on YouTube by Independence Day. Take care everyone! ========================================= Jeff Brace VCF National Board Member Chairman & Vice President Vintage Computer Festival East Showrunner Vintage Computer Federation is a 501c3 charity https://vcfed.org/ <http://www.vcfed.org/> jeffrey(a)vcfed.org

Old "beige boxes" free to a good home
by William Dudley 20 Jun '22

20 Jun '22

They're not all beige, but most of them are. These are "too new" for the museum, but I figure some of you are fixing up 1990's boxes so you can demo Windows 3.0 or Desqview or Linux installed from floppies. These are mostly early Pentium boxes (one Athlon). Some are empty cases, most have motherboards. Most have no hard disk. The item numbers match the numbers on the units in the photo. I'm happy to supply better photos or more information. Floppy drives are 3.5" except box 10 which has a 5" floppy. All the units are in Jackson, NJ. Shipping OK at your cost, or I can deliver to central NJ. Take one, take all, the rest will be scrapped, as much as I hate to see things go to landfill. Note that No. 11 has monochrome video and includes an amber monochrome monitor. It was my home router for many years, hence the 3 Ethernet cards. It used to boot Linux Router Project off the floppy. It runs the BIOS code successfully, but it won't boot because the cmos battery is flat. (NIC == ethernet) I don't want to start breaking these units and sending people things like floppy drives; If you want a floppy, take the whole box and deal with the rest of it. (That is my position at present.) 1. mini tower: 1 GHz cpu, 2 HD, floppy, CDRW, NIC, sound, video 2. mid tower w/DVDRW, otherwise EMPTY. Transparent side panel, built in handle on the top; apparently for the "gamer" market. 3. mid tower Pentium II, NIC, sound, video. Has HD in a removable carrier, plus a second empty carrier. (I need to find one of those stupid little barrel keys so I can unlock the carrier that has a drive in it.) 4. Dell mid tower: silver front, Celeron, no RAM, has DVDRW, HD, Vista license sticker 5. "Athlon 64 3000+" 2GB RAM 3" floppy SCSI CDROM mid tower 6. Acer "1120SX", but replaced original mother board with 386 motherboard (no HD/CD) floppy, NIC, video; small desktop form factor 7. Packard Bell pizza box: 200M Pentium CDR floppy 850M HD 8. Compaq mid tower: Pentium RAM floppy video 9. "Comtrade" mid tower: AMD K6 233 sound, NIC, Tseng video, 192k RAM ASUS MB (if the post-it note is to be believed). 10. Gateway 2000 tower: DVDRW 5" floppy, otherwise EMPTY 11. "IMAGE" desktop: 386 3 NICs, 3 1/2" floppy, monochrome video card, w/ amber monitor Bill Dudley Jackson, NJ

Hello all, I dedicated this episode of my Youtube channel to Dave’s memory:https://www.youtube.com/watch?v=Wo-mPpnD0K0&list=PLOW4_Hp8_912j1Tzu-… <https://www.youtube.com/watch?v=Wo-mPpnD0K0&list=PLOW4_Hp8_912j1Tzu-zN40mpz…> Feel free to share the playlist with anyone you think may be interested in the content. I make it primarily for myself, to get ideas out of my head and practice video editing skills. The global chip shortage has made it difficult for retro hardware makers to source working programmable sound generator chips such as the AY series, and continue supplying modern versions of legacy hardware. Modern replacements often do not give 100% functional compatibility with features of the older chips, which were exploited in interesting ways by developers to achieve desired effects. Thanks, Eric

passing of MIDI developer
by Herb Johnson 16 Jun '22

16 Jun '22

https://www.nytimes.com/2022/06/08/arts/music/dave-smith-dead.html Tonight I had a taste for some MIDI music. In searching the Web for it, I came across this obituary of Dave Smith, who passed a week ago. Known as a synthesizer designer of the late 70's, turns out he collaborated with Roland to create the MIDI specification. This is a little out of my interests; but MIDI is really familiar to anyone who did personal computing and digital audio instruments in the 80's. Maybe arcade games too, that's how they sounded. MIDI is both a simple cabling and serial interface to connect digital audio instruments to a computer; and a specification for codes to represent instruments, tones and duration. Something between sheet music and a piano roll. The instrument renditions are pretty simple: square and triangular waveforms with envelopes. Not a hard program to write in 8-bit assembler, a simple D/A, even a 1-bit R/C network. It's incredibly data-compact to represent a song by notes and instruments. That mattered with 70's and 80's computers and later with consumer electronic piano keyboards, drumsets, etc. But to this day, a Web browser and most audio playback programs can play a MIDI file. So I thought I'd give a shout-out as I'm listening to a MIDI theme from Duke Nukem. MIDI piano works pretty well too, there's lots of piano-roll to MIDI out there. So a Scott Joplin tune from 1902, realized in MIDI, sounds alright. Or Gershwin! 89K bytes: https://www.midis101.com/free_midi/68230/Gershwin__Medley_From_An_American_… regards, Herb -- Herbert R.
