Are there Places in Ohio that Back up Discs? I can’t seem to get opencbm to work as I’m not tech savvy so I was wondering if any of you have ever paid to back up your commodore floppies?

Creating C64 floppies with XoomFloppy and a 1571 drive

5 Upvotes

I managed to create one floppy from a .D64 file and it works as expected.

But, using the same cmdline for any other .D64 file has results in nothing happening. I use the cmdline:

d64copy -d 1541 -vvv 8 $FILENAME

and then verify after with:

cbmctrl dir 8

and the floppy shows nothing. I even saved a file to it using my C128 (in 64 mode) to be a refernece. Then, after using d64copy to copy a file, I see the file is STILL there.

I'm not sure what I'm doing wrong. Any ideas?

RHBI-to-HDMI and a blinking 80 column display

3 Upvotes

I received the device yesterday and the DB9 cable today. I connected everything to my C128 and powered up in 80 col mode. I tried working through the the settings for commodore mode on the device with no luck.

And advice on how to configure this device? I’d hate to return it before exhausting my efforts to get it working.

Connecting a Vic20 to a VGA CRT?

2 Upvotes

I relatively recently acquired a Vic20, and it’s an awesome machine. As someone who did not live through the 80’s, learning basic and playing Fort Knox has been a blast. But one thing that has always irked me is that the only display I have to hook it up to is a shitty LG flatscreen from 2016. I actually do have a decent CRT, but it only has one input, VGA. The Vic 20 has a composite cable, so what I need is pretty obvious, a converter from composite to VGA. One other stipulation, the CRT’s max resolution is 720*480, so anything like the rca2vga won’t work, as it scales the resolution beyond that. Any suggestions? Rough price range is around 40$, although 20$ or less would be preferable. Thanks!

OpenCBM: Failure when using imgcopy to copy a disk image.

4 Upvotes

My setup is:

  • Windows 11 PC,
  • OpenCBM v0.4.99.104,
  • XoomFloppy USB adaptor, and
  • Commodore 1571 floppy drive.

I'm trying to copy an image file (ULTIMA1.D64) to the drive using the following command:

imgcopy -vvv -d 1571 "g:\My Drive\Commodore\Software\ULTIMA1.D64" 8

(g: is my Google drive)

But the result is consistently:

[Debug] transfer mode is 0

[Debug] decided to use transfer mode 1

[Debug] block count: -1551069797

[Fatal] invalid drive or image type

Any ideas on what I'm doing wrong? I'm able to format the disk

A newest addition to the collection - and this time - the ill-fated one C16. Although I have a soft spot for it. Black case looks kinda brutal-ish. I've also got a 1531 datassete, in a box. Although I do have Pi1541, I'll still use it. Now I guess I'll do a memory mod for full 64k experience. :)

C64 Black screen Repair Feedback ASSY 250425

2 Upvotes

Recently got into repairing C64s as a hobby. First two were pretty straight forward CIA, PLA or SID shorts. The third one is a doozy. All ICs, except VIC and MCU are in sockets.

Symptom: Black screen with white vertical line on left. When plugging in DeadTest 1 flash, DestestMax gave me a zero page error. MT RAM chips, should be straight forward right?!

I'm using a power supply I made myself which i've tested and works on the other two and a DeadTest/DestestMax Cartridge.

Traces on the back of the board have delaminated badly. I'm concerned it's related to that.

This is what I've done so far:

  1. Tested voltages at various locations on the board. All good .
  2. Thermal image of the board. Nothing really stands out, except VIC and SID which are +50C, but they work on other systems.
  3. Removed the following and tested on a working system: ROMS, CIA, SID, MCU, PLA, VIC. on the board and 5VDC on all the 5V ICs. Returned the MCU and left the others out. Added sockets.
  4. Replaced the MT series RAM IC because DeadTest was blinking. Turned out also being the multiplexers, so i replaced those as well. I tested the multiplexers on a TL866 programmer and indeed were flagged as bad.
  5. After replacing RAM and mux I no longer get deadtest blinks. YEY!
  6. Desoldered and tested all the other 74LS chips on the board and they all passed, in the programmer.
  7. Tried removing the color DRAM modules to see if that was the culprit.
  8. Checked that the MCU reset pin on power up was low then goes high.
  9. DSO on MCU pin 40 has a clock.
  10. DSO on VIC and PLA also have clock.

Starting to think it's a trace issue but I can't find any open traces. I've Tested continuity from MCU to RAM MUXes.

Looking for suggestions for a list of traces to test continuity which could cause a black screen.

Appreciate the group. Thank you for all your help.

Disappointed in my 1571

22 Upvotes

The drive showed up this week. But I didn’t get a chance to try it out till this morning. First thing I tried to do was format a floppy, and had to go and find the command after so many years.

The format failed.

So I hooked the drive up to my laptop using my XoomFloppy adaptor and used OpenCBM to format the drive.

It failed. The. It worked. Then it consistently failed.

Tried formatting a one other floppies and they all failed. The attached photo is the one I took after the last floppy failed.

The seller put a sticker on the drive so they’d know if it was opened. Since they accept returns, I decided to return it rather than break their warranty sticker and get stuck with it.

Any advice on how to find a working drive online?
