XU1541 USB Adaptor

rhurst · Post by **rhurst** » Mon Sep 21, 2009 6:12 pm

I never knew there was a USB adaptor: XU1541 USB Adapter. I've purchased their serial versions, dumb and smart, and had a lot of success using both Star Commander and OpenCBM. This looks pretty good to have. Any personal reviews?[/url]

Mmmm... That would interest me. Do you think it will work with a "modern" netbook? If so, which program(s) should I use to load .prg and/or .d64 files into the VIC memory?

Sorry for this naive questions

XU-1541 works fine with modern Laptop or PC.

It is for connecting a commodore drive to a PC. You can use OpenCBM for transfer D64 images from/to disk drive

So, no way to actually load programs from the PC (i.e., use the PC connected via USB as a virtual disk drive)?

Via USB no, via LPT yes.

But we work on a SD2IEC with USB connector, which has optionally IEEE-488 (SD2IEEE). So maybe in a few month ...

I'll patiently wait for that.

A normal SD2IEC or a FE3 (with integrated SD2IEC) is no solution for you?

You can simply write D64 or PRG from PC to SD Card and load from VIC.

Yes. I already use MMC64 with my C64, and a similar solution would be OK also for the VIC.
Unfortunately, I have to wait for Jim Brain to produce a new batch of SD2IEC, which is temporary out of stock.

Furthermore, MMC64 won't allow multiple load from a d64 image- can you tell me if SD2IEC has the same limitation?

PET newbie question: Does that mean compatibility with PET computers?

Why not a FE3?

It has a full SD2IEC + 512KB Sram + 512KB flash memory.

SD2IEC also can mount 1 d64 image. It isn't possible to appear as 2 floppy devices (9 and

. Either as device 8 or 9 (10, 11).

Yes!

But not only. Nils will produce a new card in near future: XS-1541-SD

Which combines thre projects:

+ SD2IEC (SD floppy for VIC or C-64)

+ XS-1541 (Floppys connected to a PC by USB)

+ SD2IEEE (SD Floppy for IEEE-488 (PET, CBM-4xxx, CBM-8xxx)

SD2IEC and SD2IEEE: only one system same time. Either connected to a IEC controller (VIC, C64) or connected to a IEEE controller (PET, CBM, CBM-II)

Wow, sounds like a Mega-Floppy to me!

Sounds like it's too much for me - I only want to play Infocom text adventures, VICtoria and some other stuff on a real VIC

.

I didn't mean this. What I meant to say was: will it be possible to load multiple prgs from a single-mounted d64 (like e.g. playing VICtoria)?

This is way beyond my expectations... computers will take power if we go on like that (at least, this is what we thought in the 1980s

).

Yes of course you can load multiple programs from one D64. After mounting a D64 it is like a normal 1541 Floppy device. Except of executing mashine code on floppy (M-E) all commands are supported.

Not for VIC but on C-64 some games consists of more than one diskette. SD2IEc solves this problem by two keys (next/previous diskette).

Great! Basing on this discussion, and being a little less ignorant about this matter, I guess all I need is:

- The SD2IEC
- Its daughter board

The daughter board can be assembled by the seller upon request, as I read in the SD2IEC thread:

The SD2IEC daughterboard can be assembled by NKCElectronics.com if you ask.

Correct? Or do I need also some specific software?

[sorry for posting these questions here, but the SD2IEC thread is quite confusing

. I'll drop these questions now, because they're OT here.]

Yes you need a 5V supply. Either from cassette port or from a adapter.

Firmware should be flashed by NKC. My NKC was flashed.

Otherwise you can flash SD2IEc by a file on your SD card. Also updates can be flashed later.
