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 programmer of over 40 of them. I have fond memories of the ZX81 as it was my first substantial commercial home computer, though I'd fiddled with more primitive ones and some homebrew microprocessor circuit designs before then. I still vividly remember receiving the 16K expansion pack on the morning of the final exam for my first degree.
The ZX81 and subsequent machines were instrumental in boosting my grant through my postgrad years. On the ZX81 front I wrote an assembler (ACSembler) and monitor (ACS debug), both sold via a small company, ACS software, established by a colleague. I recently noticed on a ZX81 site that the ACS Software stuff is listed as missing in action. Having no copies myself I've made an attempt to recover them. Sadly my colleague dropped off the perch a couple of years ago but a member of his family will have a rummage through the parental loft in the near future, see whether any ACS titles have been stashed away there, and pass them onto me. There is therefore a slight possibility that everything is not lost and can be donated to whatever archive site is appropriate. Of course, if anyone on this board has any of the ACS titles I'd appreciate a copy. Thankfully the ACS programs for the Speccy (Ultraviolet and Infrared) are archived on the net.
I recently bought a doer-upper ZX81 from eBay and the doing has been well and truly upped. I've therefore been spending a pleasant time over the last few weeks writing cross-assembled machine code utilities for it. I'm hoping to get a ZXpand if and when they become available again (my name is on the list).

Welcome to our forum
If you do want help, please do ask.
Simon would no doubt love extra Zeddy software to add to his site
World of Spectrum also hosts Zeddy software New site (under construction), existing site.
Spectrum Computing also supports ZX81 software.
