This explains why my other 1541 started having read errors all of a sudden. After opening it up, it was clear that it was indeed the cause.
Now that us quite the groove on this floppy disk. Fortunately Track 18 was OK, so i was able to recover the majority of files off of it. I guess aging has caused the magnetic material to come loose on this one. This explains why my other 1541 started having read errors all of a sudden.

Today I have a new toy to play with. All the way from the UK. This is a modern full scale replica of a C64 like the C64Mini (which I got in 2018), however this baby has a working keyboard and also emulates the Vic-20. It also comes with some built in games, , however I can also play any of my own collection off of a USB stick. Pretty cool.
Rebuilt my 1702A EPROM programmer so that all those ugly "wall warts" are hidden in this case. Also built my latest revision of my Vintage EPROM reader for the Arduino.
Honey, someone shrunk the 64! Got this for Christmas from my wife. Not a bad little beasty. Some of the built-in games suck, but I can always use some of my collection.
I have been playing around with the Arduino Mega in order to use it as an EPROM reader. My ultimate goal is to use it to check old Commodore ROMs and PLA chips to see that they are working correctly. Also, with some modifications, I hope to be able to read some old 1702A EPROM chips from the 1970s. These early EPROMs need two voltages, +5V and -9V, which makes it a bit trickier. I have to make up a special personality board for that one.
So far I have been able to read the following EPROMs: 2716, 2732, 2764, 27128, 27256, & 27512.
Checked out this year's World of Commodore. Seen some neat stuff. Listened to some good talks too. Finally got around to checking out Toyratt in Milton. Excellent place for those of you who are into retro games, computers, ghetto blasters etc. The owner is quite a character. Very helpful and interesting to talk to. Definitely worth a stop, if you are in the area.
Today, I received a Pocket Modem for the Commodore 64 computer. Made by the Canadian firm Bot Engineering,in Campbellville, Ontario, this was the best modem money could buy back then. I used to own one of these when I was in high school and used to dial into places like NASA. Of course it was long distance so I had to wait until after 11 when the rates were 2/3rds off. Even then, I could not stay connected too long, or my mom would have not been pleased when she got the bill in a month's time!
By coincidence, when I was working for AECL, I visited Bot Engineering north of Hamilton, to witness acceptance testing of some radiation equipment we were buying. What a small world. |
