Further 8bit Acorn goodness

Oh yes. A weekend of R&R at home prompted me to continue a couple of little projects that don’t take too much energy.

Namely, fitting an MMC interface to my BBC Micro, providing the little Beeb with a whopping 128MB of storage. All right, so it’s not quite that much, but it does give it access to 500+ virtual floppy discs which, if you don’t know, is plenty.

Whilst I was in its innards, I took the liberty of adding a 3.5mm headphone socket to it, just because I could.

I’d also dug out my old Microvitec Cub monitor out of the bottom of the wardrobe recently, and having finally cobbled together the relevent lead, plugged it in. A what do you know? It worked. Not bad for a 25+ year old monitor that hadn’t been used for the last 19 years…

So, in all it’s glory, I present to you my BBC Micro:

And my BBC Master:

The full specifications of these beauties are;

The Micro:
Issue 7 motherboard.
32K on board RAM.
1770 Floppy Disc Controller (with DDFS)
16k Sideways RAM expansion.
MMC Interface.

The Master:
128k on board RAM.
CF Card Interface.
6502 Internal Co-Processor.
Dual MOS (switchable).

Now, I’m pretty happy with these setups, however there is, of course, always more that could be done!
Am still sorely tempted with Retroclinic’s USB Upgrade for instance…
One day.

Retro Computing

I’m a bit of a lover for retro computing, by that I mean the heady days of 8bit computers! Being a kid in the 80′s I grew up around the likes of the Commodore 64, the Atari VCS and most importantly, the Acorn BBC Micro! The BBC Micro was my machine – I had one and it rocked! Ah, the memories!

Years later, one the world wide web had caught on, I discovered the joy of emulators and was able to play the likes of Repton, Elite and Exile once more!

Then, more recently I got my hands on my original BBC again, managed to coax it into life and hey-presto, I was transported back to being a kid in the 80s. Emulators are good, but you can’t beat the real thing!

I needed to scavenge a few parts of of Ebay and enlist a bit of help from some knowledgeable fellows, but i got it working!

Yes, that is an 80′s 8bit BBC Micro home computer connected to my 21st century plasma tv – deal with it!

Even more recently I laid my hands on the best thing ever*, A BBC Master Computer!

But that’s a topic for another post…
