In my never ending quest to burn bipolar proms I have acquired a pin-master 48.
I have an rs232 interface cable to connect it to my windows 98 pc but can't get it to communicate because it says I'm missing the mqpport.vxd driver.
I have installed the promdriver software from the mpq site but...
After waiting a long time for the memory chips to turn up I finally got my mk14 replica working but with one strange thing.
I get the 0000 and then there should be two spaces and then 00 but in the second space I get a reverse C.I've only messed around with the mem and term buttons to test...
Progress!
Nascom still not booting but thanks to that neat idea of using an eeprom in place of the prom I can confirm I've now got data going to and from the rom/ram chips.
The reason it's still not booting is either the eeprom is too slow (It's a 27C040) I've got the wiring slightly wrong or...
I'm currently fixing a Nascom 2 (http://www.vcfed.org/forum/showthread.php?57307-Nascom-2-Troubleshooting)and need to replace a prom that I think does some sort of decoding.
Looking here:http://www.nascomhomepage.com/pdf/nas2proms.pdf it's a IM5600CPE the equivalents of which I put into the...
Just got one of my grails.a Nascom2.
Got it powered up but just getting a screen of random characters.
Not tried much diagnostics yet but have noticed 2 LEDs on the motherboard but can't seem to find out what they indicate.
Anyone know their function?

Unfortunately I can't find a good copy.The manuals here:http://www.microtan.ukpc.net/ doesn't have the listing
and this...
I am now trying to do this composite mod for my TI99/4A:
http://www.ti99.com/ti99r1.htm
I have followed the directions and tested and insulated all my connections but on two T.V.'s (both lcd) I get a barley visible grey screen that is like a poorly tuned in aerial signal.If I use the aerial...
So I've got the expansion interface working with my video genie and it came with a matching dual disk drive but unfortunately the second drive isn't spinning.
It's a TEAC FD-50A and I presume it's the motor that spins the disk that has failed.It's marked as a TEAC 05279 and I'm wondering if any...
I have just acquired a EG-3014 expansion interface for my video genie (same as the x-4020 expander) that worked for a while but has now died.I have traced the fault to the 15v transformer in the PSU.
I have sourced a similar transformer but it's rated at 6A and I can't find out if that's too...
So I got my nanopeb and have it working but it seems like unless I have an extended basic cart I won't be able to run much.It there a way to load extended basic into ram or am I stuffed till I can find an extended basic cart somewhere (they seem pretty rare).
I'm in the UK-Would an American EB...
