Re: Suggestions on Plus 4 problem?

Well all logic levels seemed good and since I could see real characters on screen during RESET, and I know that the KERNAL ROM also contains the character data, I figured it must be good. I started doubting the DRAM, they do go bad, usually they get quite hot but none were running hot. However the b...

Re: 28 pin DIP EEPROMs

Thanks, I'll look into it. I finally ordered a device programmer to handle old chips so as soon as I get it, I can try to read my Plus 4's BASIC and KERNAL.

Re: What's a fair price for a 1581 drive

Yup, those things are like talismans or something these days. I also have a 1571 in box, a guy at work 20 years ago asked me if I liked "old crap" I said "sure" next day he brings me the 1571 in box -- free. :mrgreen:

Re: What's a fair price for a 1581 drive

ooooh and I forgot: you can set the device number with easily-accessed switches on the 1581, as on the 1571 and 1541-II.

It doesn't head knock when formatting. It works great with a Super Snapshot. etc...

Re: What's a fair price for a 1581 drive

Well besides the greater storage space it is also smaller, quieter, cooler, and more reliable. Plus it looks so cool. Well for a nerd like me. Indeed on a 128 it is also faster since the 128 has improved serial transfer built-in. This also works with the 1571. I might be wrong but 3.5" media is more...

Re: What's a fair price for a 1581 drive

Check sold items on eBay. You can ask 200-300$ US apparently and they're not even good-looking or with the box! And to think I have a complete one in-box...
They are definitely a coveted item.
"fair" is a nebulous concept. Fair for me or fair for my neighbor are two things.

Re: Please support the Mechboard64 C64 keyboard project.

Seems like a solution in search of a problem. The breadbin keyboard sits high and is not very comfortable for longer periods of time. A SX or C128 keyboard is much better, and the 64C is pretty good too.

Also, I'm not sure what "HeadOverHeals" is supposed to mean, perhaps you meant "heels"?

Re: Suggestions on Plus 4 problem?

I looked at U21 which is part of the special address decoding of the +4. In typical cheap-ass Commodore fashion they use unbuffered outputs from U21 directly to the expansion ports. Not even a 10R resistor in series. Joyful. If anything goes wrong on the expansion port it can destroy U21 but it seem...
