ROM programmer
ZXNet echo conference «hardware.zx»
Hello, All
I decided in my spare time to build myself a programmer for 27С512 - 27С040
Looking through the diagrams of computer programmers, I remembered that once on
A programmer circuit specifically for ZX flew through the radio market. True, corresponding
There was no software then, and the scheme was thrown away.
Does anyone have a schematic for the subject with the corresponding software? IMHO, flash ROMs for
Spec is still more fun on Spec itself :)
Hello caro
to caro:
Thank you, downloaded, enjoy!
Hello jtn
I don't argue, flush is better. True, I didn’t compare the cost...
But the problem of the programmer has not yet disappeared :)
Hello, ewgeny7
As an option, you can propose a rather ancient and ineffective circuit based on
580ВВ55. But you can use it, although it is inconvenient. The circuit and software flew in
magazine "Black Crow", it seems N2 (N3, N4?). Connects to signals
processor, “sews” 16Kb pages (selecting pages using jumpers), feeding
The programming voltage occurs, in my opinion, in manual mode.
Hello, ewgeny7
why do you need 27xxxx. Shay flash! I have my own programmer for Finnish ports
(1f, 3f, 5f, 7f), but it’s raw... they say it was a software and atm thing.
turbo.
as an option - you look for old, dead motherboards, where they are suitable for BIOS
both under tqfp and under deep, you cut out, solder the pins and socket under tqfp,
you take a 5 volt m/c of Beavis and that’s it!
