We had a great turn out. We had 10 folks show up to chat about Apple II stuff. Here's proof!
Along the left side we have, Sharon Knoblock, Carl Knoblock and Greg Nelson. At the top o the table is Tom Ulrich then coming down the table we have Bill Malcom, Luke, Dain Neater, Roy Miler, Roger Quering, and Finaly, Ed Eastman.
The meeting started promptly as so many of us were on time. (How did that happen?) We greeted and sat down and ordered drinks.
Roger Quiring appeared shortly after. He is destined to be a new II user. He wants t have a 575 with a IIe card but will probably have a IIgs long before then. Ed is working with Roger to arrange this.
As for the items on the agenda:
1. Tom's Mac stuff: Tom got a bunch of Mac stuff at a University auction last month. I didn't any more detail than that.
2. Greg's oversampler software demo: There was no chance to get the hardware and software inplace to do a demo at the Perkins. But Roy thinks he may be able to get his Apple meeting room set back up reletively soon.
3. Ed's 20Mhz IIgs Project: Ed explained his theory of operation. Tap signals from the FPI chip, tap the CPU socket, make a DMA register and a Memory bank register on the card to avaois the CYA bottleneck. Add some SRam to avoid the DRam refresh complications and clock the IIgs at 20MHz against the ram. Of course that means we leave the door open for 20MHz DMA and a DMA against all banks of Ram, all 16 Meg, less Rom and Slow ram. The CPU will be clocked with the Main board clock whenever accessing I/O, Rom, or when the speed register is set to slow. THis should make it software compatible with most software. But it will eliminate the current ram cards as the CYA chip will not be used to control memory addressing. The memory slot will no longer function. However, all the slot cards should work normally. DMA at the slot will be limited to regulat main board speed, but consideration is being made to do DMA at accelerator speed for IDE or ethernet options that may become available.
4. The IDE card did not arive yet from Garber Street. Count on a review at the next meeting as it is supposed to me in the mail this week.
