|  SVS did you have these?
Ran across this in old correspondence with Christian (Solder)
Hello Jim,
Stereo-SID. Wich adresses for the 2nd sid? Maybe $fd40 and $fe80 as adress? This
is the simplest way because it's easiely to reprogram the GAL with the new
adress. I hope so because I made a lot of other hardware and I doesn't want,
that different hardwares use the same adresses. So I send you a list of all
known hardware in I/O-Area:
$fd00-$fd0f ACIA
$fd10(-fd1f)Userport 6529B
$fd11/$fd12 Internal Printerport (by me)
$fd13/$fd14 OS96 low/high-Switching (by me)
$fd15 CSORY-256kb-expansion (CSORY and me)
$fd16 Hannes-256kb-expansion (Hannes and me)
$fd17 EPROM-/sRAM-expansion (Hannes and me)
$fd18-$fd1f free if decoded, otherwise Userport
$fd20-$fd2f decoded by PLA-Chip, free, but used by different hardware
$fd30-$fd3f keyboard 6529B
$fd40-$fd5f SID-Card (me)
$fd5e/$fd5f Digiblaster (stolen from SID-Card, because unused by SID-Chip)
$fd60-$fd7f max. 4 further userports, developed by me (new!!!)
$fd80-$fd8f joyport at SID-card (bad decoded, I know)
$fd90-$fdcd free
$fdd0-$fddf ROM-banking
$fde0-$fde1 MIDI-Interface (by me)
$fde2-$fde3 Real Time Clock but I think never released by me.
$fde4-$fdfe free
$fdff Control register at external sRAM-card (by me)
$fe00-$fe7f free (good for a RAM-expansion with 128byte-window-mapping...)
$fe80-$fe9f SID-Card (only for compatibility with hungarian programs or stereo
sid) (by me)
$fe9e/$fe9f Digi-Blaster (stolen from SID)
$fea0-$feff Floppy 1551
ok, thats all. Best wishes from Christian (Solder from Synergy and Thunderbirds
Team.)
