- At one time I had this unit working, but neither I nor the person
- I got it from can remember the startup Sys address. Does anyone know
- it?
- I have tried a lot of even boundary addresses without any luck.
-
- For those unfamiliar (and interested), C64-Link is a small (2-
- 3/4"x2-3/4"x7/8") interface box which plugs into the cartridge port of
- a C-64 computer on one side, and connects to an CBM 8250 disk drive,
- and parallel IEEE printer, on the other side. C64-Link makes Basic 4
- commands and parallel IEEE hardware available to the C-64 to emulate a
- CBM 8032 business computer.
- This unit is serial #502558 and for some reason it works exactly
- right only with the older brown C-64's. (I'd like to use it with a C-
- 128 eventually but I guess that's unlikely.)
- Inside it has three IC's: a 40-pin, a 14-pin, and a 24-pin with a
- covered window which is obviously an eprom. The eprom is Hitachi
- HN462532G. The others are unmarked. Also (5) 10K resistors, (1) 1.8K
- resistor and a .001uF capacitor; that's it.
- It was made by RTC (Richvale Telecommunications) of Ontario,
- dated 1982.
-
- Any help would be appreciated. If you post, please send me an
- email copy since I'm concerned that I might miss the answer. Thanks.
