The HP Integral PC was a portable 68000 UNIX based computer introduced in 1984. The computer included a floppy drive as mass storage and a printer was built in. The screen was a electroluminicent screen. The computer has a HPIB connector to attach to external devices. External disks can be attached through HPIB.

The computer has a two expansion slot where various peripherals can be installed. For example serial boards or memory expansion boards. It was also possible to install ROM boards. The software engineering ROM has 2Mbyte of ROM expansion and when installed appear as 8 disk devices in…

IPCMemoryExpansion: common questions

What microcontroller does the IPCMemoryExpansion use?

The IPCMemoryExpansion is built around the STM32F407ZETx, from the STM32 family.

How big is the IPCMemoryExpansion PCB?

The IPCMemoryExpansion measures 185 × 116 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the IPCMemoryExpansion?

112 components, from 37 distinct parts. The full bill of materials is listed on this page.

Where can I download the IPCMemoryExpansion design files?

From the MattisLind/IPCMemoryExpansion repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the IPCMemoryExpansion design in my own project?

Yes, under the terms of its MIT license, which MattisLind chose for the repository.

Can I test firmware for the IPCMemoryExpansion without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
