Hi guys! Today I finally received the two old C64 IEEE-488 interface modules that I ordered a few weeks ago. After opening them, I guess they look pretty interesting. Before I got the pack, I thought I should receive two standard C= IEEE interfaces with the well known circuitry (based on a 6525? or something similarly rare MOS chip). But no. The interfaces were manufactured by Novotrade Fotoelektronik Gt. (a well-known Hungarian C= hardware support company in the middle '80s). Inside, I see a 6821 PIA, a 2732 EPROM, a 74ls04 and a 74ls139. Anyone ever seen such thingy?... ...Maybe I'm just naive :-( My personal opinion is BTW that they should be just slightly "economized" variants of the original C= IEEE-488 interface. ...Will have to dump out the EPROMs, but for that, I should desolder them :-/ (...or check the board and see if I can read them with the C64 itself). L. Message was sent through the cbm-hackers mailing list
