The CBM 610 PLA is now available as
<URL:http://www.funet.fi/pub/cbm/firmware/computers/b/pla.zip>.  According
to the service manual (314010-06, page 4), the 82S100 should have the part
number 906114-04.  The C64 has 906114-01.

Hello Marko,

thanks for forwarding my inquiry to the proper place - I already have some 
feedback to pursue :-).

Attached come the files for replacing the PLA (Commodore Part#906114) with a 
standard PAL16L8:

* 906114.PLD source, equations and testvectors
* 906114.JED compilation for PAL programming device
* 906114.PIN pinout
* 906114.FMP fuse map

I'm almost sure that everything is correct, but I'd like to have someone 
review the stuff and give me some feedback. I currently work on an 
EAGLE-Layout for the adaptor socket. How shall I provide the layout? 
EAGLE-Source (BoaRD-File), PostScript or Gerber would be possible.

Best regards from Braunschweig (former home of CBM Germany!)
