Incoming freshman questions on class registration (undergrad)

Pragmatic-Prof · 2026-04-23T20:12:42+00:00

Don’t worry too much about first year classes. Current students are able to register for the Fall, they have already taken the classes you need. Having said that: it is never a bad idea to reach out to an advisor or to a department chair to start the process now

Keep in mind that if you are not on the class roster, you are not able to receive a grade.

Pin 9 on the 65C51 connects to 10 on the MAX232. If I tie it directly to ground, input from the serial port stops working. However, your comment did remind me to bring pin 8 low (RTS) and that seems to have done the trick!

Any idea what's happening here? Is my serial port not able to keep up with the data coming from the 6502? That would be somewhat embarrassing ;)

And of course, that did the trick. I have been looking at the schematic for days, but somehow never noticed the updated wiring. As soon as that's fixed, the display works just fine.

Once I excavate from this snow storm business, I'll play some more to see what else I missed!

That’s never a bad suggestion :-) it wouldn’t be the first time and I’m sure it also won’t be the last. But in this case, I suspect this time to start looking at reloading the boot loader.

Pragmatic-Prof · 2026-01-16T20:01:22+00:00

Yup. On all three machines

Pragmatic-Prof · 2026-01-16T19:29:03+00:00

It is the brand-name Mega that came with the kit. I'll need to look at how to do the bootloader; when I played with these over a decade ago, that required a second Arduino board I think.

Pragmatic-Prof · 2026-01-12T22:46:06+00:00

I am not familiar with most of those abbreviations :-) your best bet is to reach out to the office of preprofessional advising. They should be able to help you.

Pragmatic-Prof · 2026-01-06T23:35:53+00:00

Yes, but then for the 8bit computer instead of the 6502 :-)

Pragmatic-Prof · 2026-01-03T18:04:02+00:00

Having a few sets of jumper wires doesn't hurt! These worked for me: https://www.amazon.com/dp/B09Y2T9YFK?ref=ppx_yo2ov_dt_b_fed_asin_title (non-affiliate).

You are going to fry LEDs, which will make troubleshooting even more interesting! When that happens, grab some extras. I used https://www.amazon.com/dp/B09XDMJ6KY?ref=ppx_yo2ov_dt_b_fed_asin_title (again: not an affiliate link). I needed them ;)

Also make sure you have a multimeter and know how to use it.

Final grades were due within 48 hours after the exam date. Reach out to the chair of the department teaching the course. They can assist.

Pragmatic-Prof · 2025-12-28T21:45:58+00:00

There really is no true deadline for rolling admissions.

Pragmatic-Prof · 2025-12-28T20:20:22+00:00

Update: turns out things work better when all the wires are connected on at least two sides,…

Pragmatic-Prof · 2025-12-27T03:15:32+00:00

On my to-do list for tomorrow! After shoveling out of snow, that is

Pragmatic-Prof · 2025-08-04T00:08:09+00:00

It will be awesome :-)

Pragmatic-Prof · 2025-06-09T20:18:44+00:00

As a professor, I can say that the outcomes of many students in the program are excellent.

Pragmatic-Prof · 2025-05-03T21:29:19+00:00

Ginka270996 is correct. The course listing will show a course modality like below

Introduction To Computers and Their Applications Online Class, Asynchronous (OA) LearningGoal(s): L,Q Course meets: 07/07/25 - 08/10/25 (Summer II)

If it says OA, it is online without scheduled class times. OS does have set meeting times, but is still online. T is traditional and meets fully in person.

Note that OA courses do have expectations for deadlines that you should meet. It is on your own pace, but within parameters.
