@pockecom_love I understand. For now, PockEmul Desktop has no way to detect which packages you previously purchased. That’s why only an active subscription can unlock all packages. I’m still actively looking for an effective solution to offer PockEmul Desktop without a subscription.
Surprising contrast: HP’s 70s–80s internal docs are public and shared by former engineers, but not so for Sharp or Casio. Why wasn’t this knowledge preserved? A real loss for computing history.
Did you know the Sharp PC-1251 has a serial port on the 11 pins connector ?
The ROM instruction is able to load a BASIC program with a simple serial protocol on pins D_IN, D_OUT, ACK and BUSY.
Unfortunately, it seems that part of the MK-92 ROM is missing.
The section responsible for sending commands to the step motors is absent.
I won’t be able to include the MK-92 in the next release, at least until the full ROM is available or the missing part can be simulated.
