Start BASIC3 without EPROM

There are BASIC3, Tiny BASIC, and Chuck's Super Monitor EPROM binaries on Lee Hart's The COSMAC ELF Membership Card http://www.sunrise-ev.com/membershipcard.htm website for his famous Membership Card. I have got some old 27C256 EPROMs but no programmer nor eraser.

But the MSC needs to have 64 KiB RAM, the standard 62256 RAM in the U2 socket and the CY7C199 (or IDT71256) soldered in U8.

Type only the bold text after the $ sign.

Get the binary from The COSMAC ELF Membership Card http://www.sunrise-ev.com/membershipcard.htm

pi@cosmac:~/elf/basic $ wget http://www.sunrise-ev.com/MembershipCard/MCSMP20J.bin

pi@cosmac:~/elf/basic $ 

Upload the EPROM binary to the Membership Card at starting address 0x8000:

pi@cosmac:~/elf/basic $ bin2elf -s 8000 MCSMP20J.bin
0x8000 bytes written

Get the binary for LBR 8000 from my site:

pi@cosmac:~/elf/basic $ wget http://spyr.ch/twiki/pub/Cosmac/RaspiElf/LBR_8000.bin
