Do you have the papertapes for this?Edusystem 5 Basic
Edusystem 10 Basic
Focal Amity
I appear to have a functioning copy (as well as a couple of less functional ones) of Amity Focal on my site. It's decus-focal8-136:Do you have the papertapes for this?
An inspection of the disassembly suggests that 0200 is indeed the correct starting address. There is a check, however to see that the switches are non-zero. If they are zero, the HLT at 4006 is taken, otherwise it is skipped. Not sure what that's about.I don't have write-up or source. From observation, starting at 00200 will halt at 04006 for some reason, and if you continue the introductory dialogue begins. (What is the correct starting procedure?)
The computer history museum's website says the have Edusystem 10 in their paper tape library.
Maybe there is a way to get a binary copy.

There's a copy of decus-8-213 here:4K ALGOL too!
There are software emulators, and they aren't even that large, but in 4K you may not want to spend the memory.Thank you both for the pointers. EAE-dependency, twice, understandable given limited memory, but unfortunate just the same. Has anyone designed/built a replacement for the venerable EAE (KE8-E)? Maybe needs a separate thread if there is a yabut, etc.
If it's just for the multiply/divide and/or extra registers, it wouldn't be too difficult to modify - but it would increase the memory requirements and reduce performance.Thank you both for the pointers.
