Using a SNES Controller for Petscii Robots on the PET Chuck Hutchins 2022-01-26 | Using the Petscii Robots SNES adapter and the Hyperkin Scout SNES controller on a real PET.Note: This is an updated revision of a video I posted two days ago. I wanted to update the video after I figured out what was wrong.The PET user port does not provide power for the adapter, so I needed to tap power from the cassette port. It turns out, the Hyperkin controller doesn't work well with the PET but I found a solution.The Scout controller feels well built and the controls are responsive. I'm sure it's a great controller with a SNES or Hyperkin console, and it worked fine on my C128, it just didn't work on the PET.Index00:00 Intro and Connecting the adapter01:24 Loading from floppy disk03:39 PET user port vs C64 user port04:11 Connecting power from the cassette port05:27 Testing SNES controller07:12 Problems with SNES controls08:40 Comparing controls with the C128 version11:25 Testing on other PETs13:39 Checking voltages, user port vs cassette port16:10 Explaining the problem and the solution18:57 Testing the solution20:12 Gameplay and outroYou can find the SNES Test Program here ...http://www.zimmers.net/anonftp/pub/cbm/documents/projects/interfaces/index.htmland other games that use the SNES controller here ...http://www.zimmers.net/anonftp/pub/cbm/pet/games/english/snes/index.htmland of course Attack of the Petscii Robots by David Murray here ...the8bitguy.com/product-category/musicMy Twitter: twitter.com/HutchCAMy Blog: blog.hutchins1.net

The polypropylene containers must be transparent to UV. The magnesium tablet solution probably blocked the UV so no sun-brightening happened there.Any number of other factors, including the keys themselves, may have made hydrogen peroxide reaction slower than I was expecting.Perifractic’s Video on Sun Brightening: youtu.be/8P1OVj0IcqYMr. Gigabytes' "13 month Speedeebrite Experiment": youtu.be/WOi6lBVIYOEMy Blog: blog.hutchins1.netMy Twitter: twitter.com/HutchCA

StarTech S-Video to VGA converter Chuck Hutchins 2021-01-25 | A review of the StarTech VID2VGATV2, S-Video to VGA converter.Converts Composite or S-Video (NTSC or PAL) to VGA (or Component)For simple stand-alone composite or s-video to VGA conversion it works exceptionally well for me.With the Cloner Alliance Box Pro, it allows me to record S-Video sources with pretty good quality.For the price though, you may be better off getting an OSSC or RetroTink instead.Index00:00 Intro00:53 StarTech VID2VGA overview03:44 Cloner Alliance Box Pro overview04:22 Direct video capture comparison05:54 Component video mode06:34 Video tape conversion08:00 VGA vs HDMI08:22 Outro08:41 Home videosI've never noticed any lag and haven't done any lag testing.I'm using a new lavalier microphone for the first time.

How to copy a cartridge game in 1983 Chuck Hutchins 2020-09-26 | Back in the 80's, all I had was a cassette tape drive and it's not easy to copy a cartridge to tape.We used a long forgotten little program called "ROMSAVE" to copy cartridges, but it required a bit of hardware hacking to allow the VIC to save the contents of a cartridge ROM.Thanks to Robin at 8-Bit Show And Tell for his generous help.youtube.com/8BitShowAndTell/featuredLink to ROMSave program: bit.ly/3j5YLNcIndexIntro: 0:00Hardware: 1:20Saving to Disk: 2:23Saving to Tape: 4:39Loading a saved cartridge: 8:47Write protecting a RAM cartridge: 10:13Summary and End: 11:13My Twitter: twitter.com/HutchCAMy Blog: blog.hutchins1.net
Trash to Treasure. PET 2001-32N restoration. Chuck Hutchins 2020-08-26 | Restoring a salvaged 2001-N that was beyond repair. I tried to sell the empty shell for a while but found no takers so I decided to have it re-coated.Probably not accurate to call it a restoration since it's not being restored to any previous condition.I had the case sandblasted and re-powder coated with a brighter white semi-gloss. I also replaced any parts I could with new parts, so it doesn't look anything like it did when it was new.I replaced the power cord, power switch, fuse holder, case badge and logic board with all new parts.I replaced the monitor PCB, yoke and keyboard with vintage parts from Ebay.Powder coating by Vaider Powder Coating, Rohnert Park, CAReproduction case badge from retromedics.comRubber feet: SF10T-TPR73-BPhotos: photos.app.goo.gl/qhKeXL8xM9wMV7AX7Eventually I may replace the keyboard with a new mechanical keyboard. There's one PCB available and one in the works but it may be difficult to attach those on the mounting rails in this 2001.I may also replace the monitor tube with a 10" LCD screen someday.IndexIntro: 0:00Disassembly: 1:13New Parts: 2:23Electrical: 5:38Top Shell: 9:13Monitor: 10:29Case badge: 11:29Final checks and testing: 12:12Results: 14:40

The audio recorder version of the Commodore PET integrated cassette drive Chuck Hutchins 2019-06-27 | A comparison between the tape drive from the Commodore PET 2001 and one of the commercial audio recorder equivalents.It seems this cassette recorder was an OEM device made for and sold by many different brands. Many have a model number or part number of CT-1020. Some say made in Taiwan and some say made in Japan, but they are externally identical apart from the colors and branding.The Commodore PET Integrated Cassette Driveblog.hutchins1.net/2020/03/commodore-integrated-cassette.htmlHigh Res Photosimgur.com/t/vintage_computing/RZ0ImF6Commodore Tape Recordersoldcomputr.com/commodore-tape-recordersMUSASHINOhttp://www.musashinocorp.com/en/profile/history.htmlCT-1020 , CT-1030 , C2N , Datasette , Datassette , Commodore , Precor C-1800 R , White Keys ,
