Hi,

Do you know if this cart work on a C64 too?

Incompatible form factor, incompatible interface, incompatible firmware.

So, no.

Honestly, I have never heard of a VIC-20 cart that works on a C64 or a C64 cart that works on a VIC-20 so why should this one which includes IO capabilities?

I thought it was a User-Port cart, like the RS232 one.

Well, it isn't. As both of you should have guessed by now, the IEEE interface goes into the memory expansion port: the cartridge contains 2K firmware to extend the operating system by the necessary logic to "talk" to IEEE devices in the same way as with the devices on the serial IEC bus, furthermore two extra VIA chips and voltage shifters and other glue logic are put on the cart. It is nowhere as simple as the VICmodem.

You find further information about the VIC-1112 in the DenialWiki.

Without that premise, rgrocha's question looked more like a query to me, whether 5 1/4" disks could be used in a 3 1/2" drive ... :lol:

I should add, that there *are* also solutions for the C64 to use IEEE488 devices. They most often also use a cartridge that goes into the memory expansion port, sometimes accompanied by a KERNAL replacement (instead of external firmware).

Two things here:
1. On the C64, the Buscard II from Batteries Included is a nice IEEE-488 interface card
2. I have seen such cards selling along with the formidable SFD-1001 drive on Amibay and Yes, the VIC-1112 will allow you to use that drive on the VIC-20.

A very hard-to-find disk drive indeed. Also, CBM 4040, 8050, and the like are very attractive and show up on Ebay from time to time, but at very high prices, and often untested :(.
I'm waiting for my brand new VIC-1112 now, but currently don't have anything to test it with! Any suggestion about other IEE 488 devices to look for (printers and plotters included)?

@orion70
I have seen more SFD-1001 drives pop-up on Amibay in 6 months than I did on eBay in 6 years. That's not to say the price was any lower.

Also, it is relatively easy to turn a standard 1541 drive into a 2031lp by adding a small interface board and changing the ROMs. Total cost is usually under 50$US.

I managed to pick up a 4040 quite cheap on eBay. It is untested but looks like it was in use until recently so I'm hopeful it will work.

Non-Commodore GPIB devices seem to be either HP or other test instruments and are very expensive.

I happend to have a Sharp JX-450 11"x17" scanner that use this type of interface but AFAIK, other than Commodore made disk drives and printers, nothing will work on a Commodore PET GPIB or Buscard-II or VIC-1112.

My Tektronix TDS-1002 is also equipped with a GPIB connector. AFAIK, only specialized National Instruments cards can communicate with that.

Sidenote: I am in need of a cable for the scanner to get it up and running again. Anybody knows of a source for that?

OK guys, thanks for all info. So I should look for IEEE 488 Commodore devices, most of which (if not all) were made for the PET and CBM series.

Another drive you can look for is an MSD SD-1 or SD-2. They have both IEC and IEEE connectors on them. They are 1541 read/write compatible drives, and you can even get JiffyDOS for them...

These drives however, are prone to electrolytic capacitor leakage, that will render them inoperable until the capacitors have been replaced and any damage to the board has been repaired. I recently picked up an MSD that's I'm going to need to re-cap, but that's what I plan on using to test my cartridge when it arrives.

Wonder what which will be finished first... my re-capping the board, or this cartridge... Heh. Game-on!

You're perfectly right and I did have one of these drives about 10 years ago.

That makes it the only 3rd party drive/device I know of that's compatible with GPIB equipped PET, C64 and VIC-20.

However, they usually cost the same as an SFD-1001 drive with only a fraction the capacity.

I have a spare msd-sd1 for sale if someone needs it (I have 3, one is boxed)

http://bit.ly/1nqpHd1

The boxed on is not for sale :)

and here is some 2031 porn for you (not all the 2031s I have)
