It isn't working with my 5160. I had another version that was working... I am looking for it now.

I have been following for a long time. I sure would like to get one of my machines online (PET 4032, CBM 8032 and SuperPET).

11/08/82 BIOS from my 5160

I also use an IDE to SD, but am having some trouble configuring it to boot to DOS. There really are not good instructions out there for this. Just people saying, I DID THIS... but no directions to explain how.

Read it all... Still no easy to order 8 bit ISA 1.44mb floppy controller?

Is the chip AM2716DC interchangeable with AM2716-1DC? The original chip is AM2716DC. Can it be replaced with AM2716-1DC?

Ok, I will give it a try.

I'm glad it works on the 8032 and 4032.

Turns out I only have 2 that work. Pins are damaged on my 3rd chip. It's very old stuff so I doubt anyone can burn the v4 bin file anymore. Maybe some are on eBay. I will need 3 more.

Yes. This is what enabled PET 4016/4032 and CBM 8032 to run Waterloo BASIC. I have a few more chips to check out. Hopefully I will have 3 or 4 of these that work.

Some success. One of my 8032 with the chip works correctly.

I don't have an eeprom burner, or know how to do it. But the chips in UD12 look like they would work (already programmed).

Another strange thing is 3 of them have UD12 populated, but only 1 of the 3 have UD11 populated. No idea what that's about.

This is what I have in UD12 of my 4x CBM 8032s. From different purchases, but 3 were in schools. I would guess the white sticker could be a serial number issued by Watcom. Sadly, there is nothing in UD12 of my PET 4032s.

The 6502 only (not superpet) - PET 4016/4032 and CBM 8032, have a chip that fits into the empty memory socket. This enables Waterloo BASIC to run. I was guessing the socket is UD12, but I don't know - I could check mine to see which is empty. What I meant to ask you, is the file you linked...

If I understand, you are saying to try drive 0 to format a new/ blank disk and see if it reads the newly formatted disk. If drive 0 does read it, then it's out of alignment (therefore drive 1 won't read it because it's formatted with misalignment). But if it won't see the blank disk and format...

Thank you. I found one online to purchase, and successfully replaced it. There are no error lights, but drive 0 doesn't read. I suspect it is out of alignment, but I am not going to repair it - just selling it as it is with one side working properly. I have two of them like that.

Are these to be burned to a chip? Is this the cracked version (1.1), or is it the original version 1? From my understanding, Waterloo BASIC is on a chip (in UD12) which is normally an empty memory slot (PET 4016/4032/ CBM 8032), at memory address $9000. I haven't specifically checked my...

Waterloo BASIC runs on the PET 4032 and CBM 8032, however it requires a chip that goes into the empty memory slot. I am trying to find out what chip/program, and how to initiate it. I expect it's as you posted the Professor doing. From high school days, I'm pretty certain we did not have to...

Waterloo BASIC will run on a PET 4032 and CBM 8032, with a chip installed in the vacant RAM slot. All of the PET 4032 and CBM 8032 in my high school computer lab could run Waterloo (Structured) BASIC. I am trying to track down the correct chip/programing. I also have a SuperPET which runs...
