I need one TDA1022 Chip to repair a piece of equipment I'm working on. Please LMK what you have. Yes, I'm aware of eBay offerings. Thanks in advance!

Steve, Hey, thank you for your fine work! Guys like you make the F/OSS world go 'round. I've not installed one on my own PET 4016, as I really have no use for 80col software, but others seem to really like your boards. I've probably sent out 25 or so to various places in USA & Canadia...

I have a few more boards arriving in about two weeks. There are currently (3) pcs that remain unsold. VCFED price is $5/ea including shipping to the USA. Canada is possible but slightly more, you hosers

No. It's nothing as common as Jupiter Lander, nor is there a "gravity" or other physics element in the gameplay. And it came on cassette..

Nah, it's a navigate-the-maze game.. fairly static, a test of nerve kind of thing. And it was almost certainly on cassette, as I never had a 1540/1 with my VIC.

Hey folks, Trying to recall the name of a game, from my earliest times as a VIC owner. This would have been ca. 1982.. It was a maze game, you could say, where you piloted a ship around the screen, avoiding walls & obstacles, scoring points (I believe..) and attempting to clear the screen...

@DeltaDon Thanks for finding that, though it's a typically info-poor YT video. Really, all points of interest could have been covered in about 20-30 seconds - and he never bothers to tell us WHICH WIRE IS WHICH, though this seems to be critically important. From the first schematic, it seems...

That's what I was thinking, FWIW. But no t knowing what it expects is bugging me. So do I just ignore the 'extra' conductor, or tie it to +/-?

Btw, I believe the original plug had a 3 conductor design: Outer cylinder, inner cylinder and center pin. So it seems all 3 conductors were being brought into the laptop case

I'd like to reuse a 19.5V Dell laptop PSU, but ran into something confusing.. The low-voltage cable (plugs into laptop case) turns out to be a "triaxial" design.. that is, starting at the outer jacket and working inward I find: Outer jacket > shield 1 > inner jacket 1 > shield 2 > inner jacket...

I have 6pc. PCB sets for the modular version of the RC6502 Apple 1 replica / work-alike project. The following boards are included in the set: - Backplane (5-slot) - CPU board - RAM / ROM board - ROM board - Serial board (uses Arduino Nano 3 or compatible) - Clock board All boards are of the...

Hi ee, Sorry about this, I didn't see an email from you nor have I been on VCFED recently. I'm really not sure what you mean by "true" 40-columns on the 8032. I've sold a number of these boards without complaint, so I can only assume that they do what's expected of them. But I'm simply not an...

As Chuck said, it's an interface which connects a physical Commodore floppy drive (1540, 1541, 1541-II, etc) to a computet running Windows, Linux, FreeBSD or MacOS. This allows you to read & write floppy discs for use with vintage machines like the C-64 / 128, VIC-20 and so on. It will make a...

Seems like almost no one wants to build a kit today, but the pre-built units are selling.. M So I'm now offering built & tested units for just $5.00 more: Only $39.95 shipped to the USA! I'm producing a small run of complete XUM-1541 II USB (PC & Mac) to CBM 1540, 1541, 1541-II, 1571, 1581...

A XUM-1541 in parallel mode is a bit more than 2X the speed in serial only mode. Altogether it takes about a minute, roughly, to read-in and write-out a standard .d64 image.

As I understand it, the XUM can be connected to an IEEE-488 drive, but you need an IEC to IEEE adapter. That said, if you have access to a 1541 (etc) drive, I believe you can make discs that can be read & written in an IEEE system. Someone in the Commodore forum will have better info on this...

I'm producing a small run of complete parts kits for the XUM-1541 II USB (PC & Mac) to CBM 1540, 1541, 1541-II, 1571, 1581 drive adapter. These kits also include the VIA (6522) adapter & cable for operating the 1540 / 1541 / 1541-II drives in parallel mode for even faster transfers. Complete...

Parts kits are currently available to ship. I have two ready to go out the door right now. Final cost is $35.00 - includes shipping to the USA. These units sell on eBay for over $50 + $$$ ship from Europe.. and they only take about an hour to assemble. I think this parts set offers a great...

A diode in series with the erase head might explain my inability to obtain a reading - but it doesn't explain the lack of a CT connection, unless it too has a series diode. The meter I'm using is my kept-handy RS 22-811. I like these meters - fairly rugged, cheap, really good feature set (for...

Hi Bob, thanks for stepping up. The MC3470 IC is present, and there are 4-5 transistors in the same area. I don't recognize the case style, but they're not the typical TO-92 - they're smaller and Iack the semi-cylinder shape. I was not aware that the head coils were fine enough to be fried...
