Re: ROMable FORTHs in 4KB

Motorola 6805

I did port my 6502 implementation ( 32k RAM + 32k EPROM ) to the MC68HC05E0. The 68pin PLCC had no internal EPROM but a direct
( = non-multiplexd ) memory access to almost 64kbyte. So there
was an external 32k RAM and 32k EPROM.
FORTH + Assembler/Disassembler 68HC05 about 16kByte.
On the 68HC05 one cannot push/pop data on the CPU-stack.
Adapted my FORTH accordingly.
That board was used as a emulator for debugging assembler-programs
for the much smaller J1A, P6, C8 with 1k, 4k, 8k EPROM.
I had used a Motorola "low cost" 68HC05 emulator and found it
a rather inconvenient time/money-burner.
As soon as the 68HC08-Flash replaced the 68HC05-OTP everyone moved
on. I still use 68HC908 both for testequipment and small volume
production.
