This might be a 2nd thread. I haven't seen my previous one show up yet.
Step by step I'm trying to bring more items back to life on the CompuPro 8/16
system I recently obtained. My system configuration is an 8085/88 cpu, System Support I, Interfacer 4, RAM22 256k, 2 x M-Drive 512k and a DISK1 connected to a NEC1165 DSDD 8". So far I can boot cp/m 2.2LD and cp/m86 1.1PD which also creates a 1024k M: ram drive. I also received a DISK3 controller which I have soldered in 3 x 7805 regulators to use in this earlier version chassis. I have had a Quantum Q540 hard drive for years which has had very little use. I verified it is good by connecting it to a WD1002 MFM controller in my IBM PC then formatted and installed
MSDOS so I know the hard drive and cables are good. So I connected it to the DISK3 controller in the CompuPro but have the hard drive externally powered by the
IBM PC. Not sure if this is good but only way I have to externally power the Quantum. I have the Quantum jumpered as DS1 (the choices are DS1-4). My hard drive cable is straight thru, not twisted. I notice when I power on the CompuPro that the Hard drive LED comes on and stays on always. Not sure if that is normal? (In the PC it only lights when selected). I have an original DISK3 formatter disk. I booted cp/m 86 and ran DISK3 Q540 ALL command. It shows the drive parameters, then asks confirmation. When I press Y it just hangs. Anyone still around familiar with this? It's interesting I can use this same disk image in Altairz80 emulation and the disk3 program runs just fine. I'm pretty sure my solder job is ok. I read 5v out of each of the regulators I put in. I have an S100 extender card, voltmeter, oscilloscope but no experience / knowledge in S100 technology or waveforms so I'm "flying by the seat of my pants" as they say. Any help appreciated.
