Sinclair ZX80 / ZX81 / Z88 Forums

It felt wrong, having written a replacement for ACSembler, not to write one for the missing-in-action ACS Software disassembler DIS-ACSEM. So, here is DISACS. disacs.zip In some ways, although most disassemblers look pretty much the same, the link here is a little more tenuous given that, in this ca...

Here is a recent rewrite of the MIA assembler, Acsembler, I wrote in the infancy of the ZX81 - and which was marketed by ACS Software, hence the odd-looking name. acsem.zip I mentioned the ACS Software stuff a couple of years ago when I joined this forum, and was hoping some of the titles might have...

I built the SDHC interface using a PIC18F25K40 which is on my main PCB along with all the other standard ACE chips. The interface relies on there being a ROM between e000-ffff to contain the low level code for communication between the Z80 CPU and the PIC, plus the new FORTH words which use that cod...

That looks like a lovely neat idea. I did a similar thing last year for my ARV1 (Ace Revamped) design but in a much bigger case - a dk'tronics keyboard one. That has the Jupiter Ace circuit with the following changes. a) ROMs are AT28C64-15 - one at 0-1FFF is essentially the ACE ROMs in one chip, th...

I don't get it :?: It does appear rather out of context with the original exchange having been a while ago, and likely exacerbated by my no-smiley policy. Explaining humour is generally a very bad idea though. As for smileys, opinions differ and one should certainly not be militant about such thing...

Ah, yes, quite right, my mistake. I forgot your distinction. I believe you. Honestly.

Congratulations! Keep up that paranoia.

Thanks all, and especially to Mark for the useful archive information.

Good morning. Having recently wandered across from stardot, C64 forums and others, subscribed under the same username, I see many familiar names here (1024mak, sirmorris, lardo etc) so at the risk of boring them with my life history once more... I'm a FORTRAN programmer for a few years and a C progr...

Argh! Missed out again! These things go faster than hot cakes. If it's any consolation I was looking at the sellmyretro entry last night and this morning. From the 8 made available there were still four left when I hit the sack and at 06.00 today there were still two. So at least you've not got muc...
