Last #SAMCoupe related #Halloween post!

"The Monster Mash", 8 to 1 ADPCM compressed sample playing through the Quazar Surround soundcard - my first hardware release back in 1995 for the SAM, and still available - latest 2024 edition: https://www.samcoupe.com

I developed this ADCPM 16-bit decompression code for the SAM Coupe in 1997. In this example with a playback rate of 11KHz ~490K of memory gives 3 minutes of audio. Updated routines gave higher playback rates and oversampling.

"The Witching Hour" is upon us for #Halloween! Grab this fab SAM Coupe graphic adventure game by John Vincent that features on the cover disk with issue 24 of SAM Revival magazine.

Great to see the SAA1099P Soundchip Interface (for #RC2014 and compatibles) in use playing some fantastic music!

Here @noisetank has the track by DJM/DTA from the #SAMCoupe demo 'Slow Motion' playing on the #ZXSpectrum with the SAA1099P Interface connected via the ZX-RC Bus Adapter.

I've got the SAA1099P Interfaces in stock, ready to ship out!

Finished implementing a very simple line editor for DX-BBS. Sure, there's much room for improvement but at least the core functionality is now in there and works.

Time for a cuppa ...

Did I ever mention RC-BOX BBS - the world's first and (currently) only RC2014 based bulletin board system?!

Running on a real RC2014, powered by a Z80, CP/M 2.2 and a highly customized fork of RBBS4 this single-user system offers you the 1985 online experience.

Text games available on the CP/M command shell !!

P.S.: connection info is in the ALT-text or in my profile info.

Morning all. I've been building up the next batch of my SAA1099P Soundchip Interfaces for #RC2014 and compatibles, so these are ready to ship! More information / ordering at my https://2014.samcoupe.com website. I've updated the community links with more of the videos/demos that have been appearing using it, plus resources for creating SAA1099P music online (Borik's SAA Tracker) which can export #Z80 code. This tracker appears to be heavily based on E-Tracker from the #SAMCoupe with a couple of expansions.

I'm also updating the PCB style of my popular SID Soundchip Interface for RC2014 and compatibles to match the style of my newer SAA interface, so it includes a little PCB computer of the #C64 where the SID is from! I've made the little C64 PCBs available as a pin badge too! (Badge: https://www.samcoupe.com/quickshop.htm)

I've three of the original style SID Ints left so I'm offering £10 off the original style. (Private Message and I can arrange this discount)

Hardware: Tatung Einstein TC-01

Although the Einstein wasn’t a popular machine it was responsible for quite a lot of the classic computer era games on 8 bit micros.

I just spent a hefty chunk of money buying this beaty, an ABC80 homecomputer. A Swedish classic. And it comes with a dual-floppy unit and a bunch of discs. How could I pass on this one?

But now my husband is a bit annoyed that I bought yet another 50 year old computer, and he told me I'd better get him a Philips NMS 8220 MSX 2 machine.

Only trouble is, they're a bit hard to find. So please help me save my marriage and let me know if you find one for sale :)

Une nouvelle occupation grâce à @altomare
C'est une carte CPU #heathkit H88 (#z80) , état inconnu !
Si tout fonctionne cette carte ira dans mon terminal Heathkit H19, mais tout d'abord il va falloir la faire marcher.
#retrocomputing

Has anyone written a Fediverse client for CP/M on the Heath Z80 yet?

Because it seems like someone in here would do that.

Would it be interesting to add ez80 support to the zenas assembler?

In my first attempt when I wrote the (still incomplete) assembler callled zxa, I had already implemented the entire Z80 instruction set, and also the Spectrum Next's-specific Z80N extensions. That didn't work too well, but at least I learnt what not to do, or how not to do it.

I'm trying to think what would be the better way to support different variants and extensions.

Some Z80 variants also existed in the world of MSX when various Japanese chipmakers produced their own, improved and extended versions of the Z80.

The question to me is not so much whether ez80 and Z80N support should be implemented, but HOW as in what's a clean way to support them. Via directives?
With pragmas or ifdefs?
Via command line switches?

What do you think?
