Well started examination on the P-500 again, dumped the ROMs and am writing down numbers... Here are some details for those interested: The Motherboard's Assembly Number is: 4256046 The 3 8k (HN482764) EPROMs are C= part numbers: 901234-02, 901235-02, and 901236-02 There is another chip marked FPLA #1 0906114-02 There is a second chip next to it with it's part label removed (dried spooge on the top), the chip ID is: N82S100N 8235 (I haven't searched the net to determine what the chip is, one day I may study electronics more....) I'll get the bianaries up to FUNET once I get my null-modem connect to the Mac re-established... :) If anyone has any questions regardng the P-500 fire away, I can digitize any part of it you may want to see. - - - - - - - - - Those who have seen the web page know the P-500 wasn't in fully functional order, I was just going to give you guys a run down but it seems to be running ok now (yippe!) I guess the ROM pulling and re-seating did the trick. --------- Also read-ROMS recently an a PET 2001 32k. Which had upgrade ROMs labeled: C000 - 901465-01 D000 - 901465-02 E000 - 901447-24 F000 - 901465-03 Char: 901447-10 Any need for these on FUNET? Will have a Wordpro 3 ROM (WITH matching program) once I jury rig a missing pin, and if I can find my chips case (a cassette tape box...somewhere) I have a toolkit or two and a diskless Visicalc ROM. --------- Next computer to be read and examined will be an Origianl ROM PET. -- -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- Larry Anderson - Sysop of Silicon Realms BBS (300-2400bd) (209) 754-1363 Visit my Commodore 8-Bit web page at: http://www.goldrush.com/~foxnhare/commodore.html -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- - This message was sent through the cbm-hackers mailing list.
