Okay, I have it all dialed in now!
With that iffy memory board swapped out, the system works beautifully. I did have some trouble loading Altair BASIC but after looking at a video of someone running it I discovered an extra line that appeared to be in the Altair patch file and also a couple of memory addresses that were altered. Once I did that, the prompts came up and it let me enter a program! The only problem was for some reason Hyperterminal was cutting off a column or two - so instead of the OK prompt I had O. I figured that was probably just Hyperterminal, so I switched the system back to 110 baud, loaded Altair BASIC, and then switched to the CT-1024. It worked perfectly! Pretty magical being able to use this software I've only seen demonstrated in videos on vintage hardware! Can't wait for the day I have a real Altair and teletype. I'm going to hunt around for more S19 files. I'd also like to learn more about how to program this thing (I assume in assembly). And then another thing on my wish list would be to have both the MP-S and MP-C cards working together in a way that I could use one to load and save stuff off to my PC terminal and the other for actual terminal interface. Thanks again for the help and suggestions!! Brad
