From Cop Car Data Terminal, To Retro Computer

It is possible that you will have lived your life without ever coming into contact with a Motorola MDT9100-T. The data terminal of choice for use in police cars across the globe was a computer with a full-sized QWERTY keyboard, a small CRT display, a mainboard sporting an Intel 386SX processor, and a custom version of Windows 3.1. [Trammell Hudson] and some friends from NYC Resistor scored some MDT9100s in an online auction and found them to be just too good an opportunity not to crack them open and see what could be done.

The custom Windows install could be …read more

Resurrecting An Amiga CD32

As an editor on Amiga magazines in a previous life, this is kind of bittersweet. [RetroManCave] was donated an Amiga CD32 games system, and it is trying to resurrect it. If you’ve not heard of it, the CD32 was a 1993 games console based on the Amiga home computer system. It was the last gasp for Commodore, the beleaguered company behind the Amiga. In this first video of a series, they take the system apart, take you through what’s inside and boot it up. The system boots, but there is some sort of problem with the video sync, and they …read more

Looking Back at Microsoft Bob

Every industry has at least one. Automobiles had the Edsel. PC Hardware had the IBM PCJr and the Microchannel bus. In the software world, there’s Bob. If you don’t remember him, Bob was Microsoft’s 1995 answer to why computers were so darn hard to use. [LGR] gives us a nostalgic look back at Bob and concludes that we hardly knew him.

Bob altered your desktop to be a house instead of a desk. He also had helpers including the infamous talking paper clip that suffered slings and arrows inside Microsoft Office long after Bob had been put to rest.

Microsoft …read more

Amiga Gets a PS/2 Keyboard Port

Name any retrocomputer — Apple II, Sinclair, even TRS-80s — and you’ll find a community that’s deeply committed to keeping it alive and kicking. It’s hard to say which platform has the most rabid fans, but we’d guess Commodore is right up there, and the Amiga aficionados seem particularly devoted. Which is where this Amiga PS/2 mouse port comes from.

The Amiga was a machine that was so far ahead of its time that people just didn’t get it. It was a true multimedia machine before multimedia was even a thing, capable of sound and graphics that hold up pretty …read more

This 6502 Computer Project Is A Work Of Art

If you were a home constructor in the 8-bit era, the chances are that if you built a microcomputer system you would have ended up with a bare printed circuit board and a terminal. If you were on a budget you might have had a piece of stripboard as well, or maybe even wire-wrap. Beautiful cases were out of reach, they came with expensive commercial computers that were not the preserve of impoverished hobbyists.

Constructing an 8-bit machine in 2017 is a much easier process, there are many more options at your disposal. There is no need to make a …read more

Almost An Amiga For Not A Lot

If you ask someone old enough to have been a computer user in the 16-bit era what machine they had, you’ll receive a variety of answers mentioning Commodore, Atari, Apple, or even PC brands. If your informant lay in the Commodore camp though, you’ll probably have an impassioned tale about their Amiga, its capabilities, and how it was a clearly superior platform whose potential was wasted. The Amiga was for a while one of the most capable commonly available computers, and became something of a cult within its own lifetime despite the truly dismal performance of the various companies that …read more

Hackaday Links: July 2, 2017

A few months ago, we had a Hack Chat with Chip Gracey, the guy behind Parallax, the Basic Stamp, the Propeller, and the upcoming Propeller II. Now we’ve finally got around to editing that transcript. There’s a lot of awesome stuff in here, from learning a Hardware Design Language to the actual costs of fabbing silicon.

Rigol, the manufacturers of every hackerspace’s favorite oscilloscope, announced a new chipset. The current lineup of Rigol scopes top out at around 1GHz. In a prototype scope based on this chipset, Rigol demonstrated 4GHz bandwidth and 20GS/s with one Billion point memory depth. What …read more

Z80 Based Raspberry Pi Look-alike

Homebrew computers are the ‘in thing’ these days and the Zilog Z80 is the most popular choice for making one on your own. We have seen some pretty awesome builds but [Martin K]’s Z-berry is the smallest on record yet. As the name suggests, the retrocomputer conforms to the Raspberry Pi form factor which includes the GPIO header.

The Z-berry is designed with a Z80 CPU running at 10 MHz (20 MHz possible) and comes with 32 kB ROM
and 512 kB RAM. In addition to the serial interface, the computer boasts an I2C bus, an SPI bus, and a …read more
