Retrocomputing is a lot of fun...

I'm having a blast hunting down my old programs and posting them on my site. I've also contacted Mike Harvey, the editor of Nibble, since I found my stash as well as John Romero when I realized one of my "uncategorized" Nibble programs was actually one of his.

I've started the slow process of placing some of my programs (nothing impressive, but the comments should prove interesting) on the web page. I haven't run out of web space, but with screen shots as well as the archive, that is a definate possibility!!

Now I just need to buckle down for my next exam as well as maybe finish one of the myriad of projects I start......

Out of date...

Wow, I just noticed that the May posts were still talking about trying to get software over to the IIGS.

For posterities sake, I seem to remember the Macintosh did work - but there was a lot of floppy copying. I finally got myself a Macintosh serial cable and a USB serial port (for the laptop). That gave me the ADB connection on the IIGS serial connector to a standard RS-232 connection. I then obtained a crossover cable which fortunately is DB-25 and DB-9 on each end so I can mix and match connections. That (finally) connected to the serial connector on the PC.

I could then use the terminal program on the PC to control the Apple IIGS via the serial connection. I got ahold of ADT 2004 and got a few disks shipped over that way. Once I had some communications programs, I could just use Xmodem, Ymodem, and finally Zmodem (with my own copy of ProTERM).

Very soon after getting all that working, I picked up a CFFA card from Rich Dreher, and he was kind enough to invite me over (ironically he lives within walking distance) and we chatted and got the card setup.

I've been developing with Merlin GS 4.12 and MD Basic. Not bad, probably ahead for their time, but nothing compared to what exists today!

To teach myself 65816 programming, I actually worked my way through the Programmer's Manual on the WDC web site. It has a number of errors, but there is enough information to identify them and the learn from it.

Project updates

Harry's Adventure is progressing, albiet slowly. I haven't done any actual development on it recently, but I have been working on a side project tangentially related to Harry's Adventure.

The Apple Image Encoder will take a modern image and convert it to some Apple II graphics modes. Right now it converts to super hires, lores, and double lores.

My intent is to be able to get Harry into the title page for his game. For the super hires mode, it shouldn't be much of a problem. The lores and double lores modes, however probably won't work. Hopefully someone can give me hints on how to handle dithering with a fixed 16 color palette to achieve what appears to be more than 16 colors, so I can create better images in the earlier Apple II graphics modes (lores, hires, double lores, double hires).
