Looking on EBay the prices for the EPROM's are just a few pounds if M27C512-15 is the same thing, the 28 pin DIL socket less than a pound, the ROM codes Minerva & Toolkit II are freely available so other than getting the code burnt on to the EPROM I have everything or am I missing something?

Hi Lee, > So I need to look out for a Gc, SGC or Minerva conversion kit, > haven't seen those on eBay or sell my retro For Minerva ROM you could try 1. Get an M27C512 and a 28 pin DIL socket (wide, long pins) 2. Program lower 48 KB with Minerva, and upper 16 KB with extension ROM binary of your choice 3. Lift up pin 1, 20, 22. 4. Press M27C512 into an IC socket 5. Wire socket pin 20 to M27C512 pin 1 6. Wire socket pin 22 to M27C512 pin 20 7. Wire M27C512 pin 28 to M27C512 pin 22 8. Remove both QL ROMs from socket 9. Press in the M27C512 with it's socket into one of the QL sockets All the best Peter _______________________________________________ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm _______________________________________________ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
