Modified version of my SAA1099P Soundchip Interface for RC2014 and compatible systems. This has different addressing logic compared to the standard version.

Where possible I'm happy to customise hardware I make. In this instance it's a version of my SAA1099P Soundchip Interface for RC2014 & compatibles, modified for use in a 6502 system which simulates a Z80 bus for RC posts, although with only A0-A7 available for decoding as the 6502 logic uses a...

Yeah, decided to have custom stuff in a different colour to differentiate them. I’ll keep all the default versions in the usual black colour.

256 byte window in the processor's memory map to act as I/O address space on the simulated Z80 bus. In order for my SAA Interface to work I had to change the I/O port decoding to remove the requirement of A8 signal.

Some of my lpMUD world from the MUD I played/coded for back in 1993 when at university.

It should be relatively straight forward to get something running on a handful of SAM Coupes, starting off with just a few players moving between locations (which I can use rip my lpMUD code) and using "say" to talk to one another. It really only needs that very rare commodity of "time" to get done!

Networked Pac-Man on two SAM Coupe computers

writing a two player Pac-Man game to use the inbuilt networking years ago. For a MUD it'll be relatively simple as just need terminal style code on the other SAMs for the other players, with one SAM doing all the processing.

The Usborne computer books I still have from the 1980s.

Great books, still have some. Usborne have them online to read for free: usborne.com/gb/books/com...

I've never bothered much with single player adventures but was hooked on MUD at university in early 90s! Need to code a simple MUD to run on 2 or more networked SAM Coupes for retro shows / museums.

Probably far easier to write something from scratch in Z80 than attempt to modify/compile bits of C for SAM! Way back in 1993 or so I did start several adventure related things to rip the room descriptions and directions out of the world area I coded for the lpMUD I was on. Also got as far as...

Computer and coding books from Usborne | Usborne | Be Curious Usborne children's coding books for a new generation

I know the book you mean, I've still got my copy. The Usborne range was great and fantastic that they put them online to read for free. I wish I had bought the machine code for beginners book back in the 80s!

the MUD coding I had done. Still an idea smouldering to write a simple multi-SAM MUD (using the inbuilt networking) to have running at retro events / museums around the country.

In terms of adventures, I was never interested in them as a kid (with ZX Spectrum) but in 1992-93 I got hooked on a MUD at university, first playing then programming for. I started on several different adventure engines for the SAM back in 1993 too, including one to rip room descriptions etc from...

SAM in a CAN 2 - an original SAM Coupe motherboard in a new case, along with lots of additional hardware built in including the Trinity Ethernet Interface (+SD card storage) and Quazar Surround soundcard. A couple are under construction at the moment for people, and I've parts for a handful more.

There'll be an adventure section in the next issue of SAM Revival! As for pulling a SAM through into this universe, 2 options coming up! Original motherboard + extra peripherals in 'SAM in a CAN 2', then original custom chip used in a new SAM for which I currently have the codename 'Pandemonium'!

SAMCo's idea of publishing ZX Spectrum software to then encourage programmers to swap to SAM Coupe programming... I've occasionally thought of the reverse. With the SAM games I've coded and other SAM game IP I have porting them to Speccy (and other platforms) could be fun! Got as far as mock gfx...🤔

In SAM Revival 22 the commercial piracy of the SAM Coupe Manic Miner by the new Revelation is discussed.

(The fab SAM version of Manic Miner does appear with permission on the coverdisk with issue 9 of SAM Revival, the paper side was revamped last year. Grab it at www.samcoupe.com/quickshop.htm)

Only one ZX Spectrum title was published by the Revelation software arm of SAMCo - Astroball. Two months after this announcement of expanding SAMCo went bust. A new Revelation Software soon appeared, completely different owner, claiming to have old software rights but didn't pay some programmers...

Although it can get a bit confusing at times! 🤪

We've already got 6502/6510 emulation on the SAM Coupe for VIC-20 and partial C64 (.sid playing with my SID Soundchip Interface). How much of a stretch would it be to emulate the 6809? A topic to explore in a future issue of SAM Revival...

Unlimited Spirits - amazing #ZXSpectrum 128K music! Listened to this a lot while waiting for my SAM Coupe to arrive that month in 1993! I use this music to test ZXTT modules I make to clock AY chips on Ed Brindley's #RC2014 YM/AY soundcard at same frequency as Spec.

This was my life between 1983 and 1993 with a ZX Spectrum 48K, then +2. Finally moved to disks with the SAM Coupe in the spring of 1993!

Assembler was covered in the accompanying lab work for the processor module. I was told to just to skip the lab work after correcting the lecturer that IN (C) / OUT (C) used 16-bit I/O ports, not 8-bit...

It was utterly baffling! BASIC or C... I'd have expected one of those instead. Drawing in 3D was what I had chosen for my project that carried half of the grade for the module. Writing in Fortran 77 with a Xlib graphics library on a Sun Workstation was such a funky mixture!

Oh the fun of 3D! I wrote line vector code in Fortran 77 during my university days - a very odd choice of language for a physics/electronics module in 1995. Likewise the module on processors focused on the Z80, which I'd been coding for already.

PCs were much more fun back in those days!

That's putting it very politely! When the major diskmag changed editor the cliquey-ness (is that a word?!) vanished overnight, and he was more than happy to include my news and feature my adverts.

When I see Psyclapse and Bandersnatch mentioned I have to point people to the BBC's Commercial Breaks episode covering Imagine and Ocean, although as mentioned by Joffa a lot of the Ocean stuff was done purely for the cameras!
