Retro Challenge 2017/04 Day 04

On My - Bad Caps.

I have the 2-pin style of VIC-20.  There is a large 4700uF cap that has leaked and corroded.  There are also two 100uF 16V caps and a 22uF 16V that also have gone bad. I was able to clean up the board and install all new caps.  There were 4 other caps (1uF 16V and 10uF 16V) that I changes that seemed to still be good.

I used the information form Console5 Tech Wiki.

The screws attaching the heat sink to the board were all loose so I tightened them as well.  The system seemed very clean with little to no bug evidence.  Obviously this system has been stored in doors and should provide many more years of use and enjoyment!

Well this is the inside.

Not to dirty inside.

RF cover removed.

Yep - Bad Cap.

I am sure the FCC was pleased.

Retro Challenge 2017/04 Day21-23 Time for a better monitor! My neck was taking a toll having the TV on top of my desk.  There is no room to have it lower so another option was needed.  I had an under the counter LCD TV/DVD in the kitchen that we no longer used so I re-purposed it to the computer room..  It is awesome!  The screen is sharp and clear.  The position is perfect!  I am very pleased with this change! The disk copying was not going well.  In desperation I tried changing my 1541 to the "UI-" setting and instantly unreadable disks were coming over without any issues!  The "UI-" speeds the drive up a bit to match a 1540 and it has made all the difference in the world!  Now I can copy over entire disks to the SD2IEC with virtually no errors.  The few files that seem to be problem files copy fine when I move them separately. I had to @0: save the files but there were only a few to copy. I was able to get through all the disks and now on the SD2IE

Retro Challenge 2017/04 Day 24 - FINAL DAY This is my finial entry for the 2017/04 Retro Cjallenge. My goal was to completely set up a working VIC-20 system and I have done that. My system includes a working VIC-20, MPS 803 printer, CN2 tape drive, 1541 floppy drive, 1541-II floppy drive, and a SD2IEC drive.   I recapped all the electrolytic caps in the VIC and 1541s. I worked out a great video display option.   I have retrieved all the files that were salvageable from 45 cassette tapes and 20 floppies. I am able to download files from the Internet and use them on the VIC-20 and I can run files from the VIC-20 on my home PC via VICE. I have leaned how to blog and share my experience. I am very happy I took on this challenge and look forward to years of reliving the past and discovering new uses in the future!

Retro Challenge 2017/04 Day 18 Oh My ... oh my ... OH MY! (Chatter chatter grind grind Thump Thump!) Well, my hope to be able to just COPY/ALL the floppies to the SD2IEC has faded away.  These floppies are old - 1984/85.  They have not been stored in the most ideal conditions for the past few decades.  The COPY/ALL or UNI-COPY works great when it is able to read a newly formatted floppy but time has taken its toll on my collection. Some files copied just fine but others caused the drive to chatter and reset.  When it was done with the copy process, there was no listing of what made it and what did not.  I can't trust that anything really copied error free so I will have to resort to a one-by-one LOAD-VERIFY-SAVE.  There are both custom files we created as well as magazines programs so I really want  to save these.  There are many. I will look into the VIC-WEDGE to see if that will cut down on the OPEN-PRINT# hoops.  Also, I need to get the printer ribbons installed so I
