Re: Attic 81's - My collection and attempts to repair

I know its not Programs but there are very convient results using ZXWESPI from the german ZX-Team.
It's very easy to install (only 4 wires to zeddy) and cheap and powerful.
Maybe thats better than involving x86 based conversions....

Re: CLKFREQ.P benchmark on 2K ZX81

As a hint for easy remembering:
Zeddy isn't clever enough to insert waitstates if a chip isn't fast enough. In this case it just does what it's it's supposed to do: it fails ;)

Re: 2 Oldies from under the dust. Can we fix them??

Gold plated sockets are ideal for gold plated devices. If the pins of your devices are golden then go for gold plated sockets.

Pokemon's ZX8CCB (or whatever they're called) are simply the best!

Re: Attic 81's - My collection and attempts to repair

I’m going to blow a chip with the latest version of the BASIC ROM later this month. When I do, I will document it in a new topic. I’ve not decided which chip to use yet, other than it will be a 32k byte type (so either a OTP 27C256 or a 28C256). Mark Hi Mark, I use Winbond W27C256. They are EEproms...

Re: Hello

Hello and welcome from me as well.
Per incident I drove through Belgium twice today on my way from Aachen to Trier and back home again ;)
With ZX81 hardware I might be able to assist.
Kind regards Paul
