---- I have some tape controllers lacking documentation, and I was hoping someone out there could tell me what the options are on the following: 1) Archive SC400S - Need to know how to strap the address of this card. Address strap is a strip of 7 jumpers labeled A3-A9. 2) Everex Systems EV831 rev. F (aka Bell Tech 60MB tape controller). Need to know the meaning of the DIP switches. Many thanks... -- ken seefried iii "A sneer, a snarl, a whip that ken@dali.gatech.edu stings...these are a few of my favorite things..."

>1) Archive SC400S - Need to know how to strap the address of this > card. Address strap is a strip of 7 jumpers labeled A3-A9. I've forgotten the specifics, but there are two varieties of address decoding on the Archive cards. Basically, the address is in BINARY, where the An label means 2^n. On the older cards, you turned bits on by jumpering the straps (i.e. A8 gave you $200, A9 gave you $300, etc). On the newer cards, you turned bits on by REMOVING jumpers (e.g. all jumpered EXCEPT A9 gave you $300 ... etc). The "older" cards were full-length and mostly discrete logic. The "newer" cards (still made, I've heard) are half-length with more ASIC's on them than discrete. Hope this helps.

Address strap is a strip of 7 jumpers labeled A3-A9. I use 0x200 as the base address on my card, but shorting pins labeled A9. If you have a game card, it will conflict and you might try address 0x300 by shorting A9 and A8. In general, you can figure out the correspondance between addresses and jumper settings. If you let A9 be the value 1 when shorted or 0 when open, the base I/O address in binary is simply: A9 A8 A7 A6 A5 A4 A3 0 0 0 Other important settings are on jumpers near the edge connector for selecting the interrupt and DMA channels. I am using IRQ3 (the jumper labeled "234567" with jumper on position labeled "3") and DMA channel 1 (jumper labeld "123123" with jumpers on both positions labeld "1"). If you are using the Archive FASTAPE software, be sure to run the FTINSTAL program to configure the software and tell it your base I/O address, interrupt, and DMA channel.
